Life and property losses because of disasters such as flood and landslide are getting dramatic increases for past years. Frequent extreme weather events have even worsened the damages globally. Given sufficient information in advance, disaster preparedness and management can be well-settled. The damages and losses can be mitigated and even prevented. An early disaster warning system with enough leadtimes is essential for decision-makers to take prevented measures and execute cautions. This study proposed a prototype of an early disaster warning system which issues warnings for rainfall related disasters such as flood and landslide. Using ensemble quantitative precipitation forecasts, the system …

International Conference on Hydroinformatics
Currently, basin-wide flood monitoring and warning systems are being implemented sequentially in river basins of the Philippines, which suffer from severe floods. The Cagayan River basin is among them draining the area of 27,280km2, where five rainfall and water level gauges are installed for the purpose of flood monitoring and warning. Despite the installed monitoring system, an operational flood forecasting model based on physical processes has not been performed for this basin. IFAS, a distributed hydrological model developed by ICHARM, was applied to the Cagayan River basin as a flood forecasting model. One of its notable functions is the capability …

Automatic Frequency-Based Flood Forecast From Numerical Weather Prediction Using A Service-Oriented Architecture, Ang Zhang, Tiejian Li, Haiyun Shi, Wang Fu, Jiaye Li
International Conference on Hydroinformatics
Destructive floods occurred more frequently in mountainous regions in China in recent years. However, the meteorological and hydrological station network in such regions is usually poor, and no long-series observations are available. Therefore, it is difficult to determine the hydrological parameters for flood discharge and stage forecast. This paper aims to propose an automatic frequency-based flood forecast framework from numerical weather prediction (NWP) using a Service Oriented Architecture (SOA). The proposed framework has 4 main steps. First, historical flood discharge is simulated by using a distributed hydrological model and satellite-derived rainfall dataset (e.g., the CMORPH and the TRMM), and the …

International Conference on Hydroinformatics
A regional flood warning system based on a combination of data processing, modelling and communication tools is proposed. The system is founded on a common framework MIKE CUSTOMISED, giving great flexibility in tailoring solutions as needed. Where more conventional flood warning systems focus mainly on discharge predictions in the main rivers the proposed system considers the whole catchment area – flood plain, as well as tributaries. Local floods on smaller streams and tributaries may cause high damages, particular in urban areas. Such cases require timely reasonably accurate forecasts for proper decision making. The MIKE SHE modelling system is used to …

The Contribution Of Fine Scale Atmospheric Numerical Models In Improving The Quality Of Hydraulic Modelling Outputs, Rabia Merrouchi, Dalila Loudyi, Mohamed Chagdali
International Conference on Hydroinformatics
The atmospheric numerical models have known great advances with the ongoing development of numerical weather prediction and computing resources. The spatial and temporal resolution of the global atmospheric models has improved and therefore, the accuracy and reliability of their results have substantially increased. Emphasis was made on the improvement of models dynamics and physical aspects, but also on data assimilation and input data diversification using new numerical schemes and new physical parameterizations that better assess the small-scale weather phenomena. However, these models were not able to overcome their physical limitations and therefore, some small-scale processes are far from being thoroughly …

International Conference on Hydroinformatics
As a highly urbanized and flood prone region, Flanders has experienced multiple floods causing significant damage in the past. In response to the floods of 1998 and 2002 the Flemish Environment Agency, responsible for managing 1 400 km of unnavigable rivers, started setting up a real time flood forecasting system in 2003. Currently the system covers almost 2 000 km of unnavigable rivers, for which flood forecasts are accessible online (www.waterinfo.be). The forecasting system comprises more than 1 000 hydrologic and 50 hydrodynamic models which are supplied with radar rainfall, rainfall forecasts and on-site observations. Forecasts for the next 2 …

Hydrological Ensemble Forecasting And Data Assimilation With An Integrated Hydrological Modelling System, Henrik Madsen, Diana Lucatero, Marc Ridler, Donghua Zhang, Jens Christian Refsgaard, Karsten Høgh Jensen
International Conference on Hydroinformatics
Hydrological forecasting is an important instrument for more effective water management, such as warning and protection against water-related hazards, real-time operation of water infrastructure, improved water allocation, and environmental monitoring. Recent advances within radar rainfall estimation and nowcasting, ensemble-based numerical weather prediction (NWP), in-situ and satellite monitoring, and hydrological data assimilation are opening up new opportunities in real-time hydrological forecasting. NWP ensemble products can be used as input to hydrological forecast models to produce probabilistic forecasts and estimation of forecast uncertainty of the hydrological variables of interest. In this regard, key scientific challenges are understanding, quantification, and propagation of the …

Floodalert: A Simplified Radar-Based Ews For Urban Flood Warning, Xavier Llort, Rafael Sánchez-Diezma, Alvaro Rodríguez, David Sancho, Marc Berenguer, Daniel Sempere-Torres
International Conference on Hydroinformatics
Urban floods can be caused by intense rainfall accumulations in short time periods that eventually exceed the capacity of the sewer networks. Despite the efforts made in the last years in all cities to increase the sewer’s capacity many cities are still exposed to these heavy rainfall events. In this work, we present a simplified flood Early Warning System, called FloodAlert, based on the use of radar observations to issue local flood warnings. Although precipitation accumulation estimates based on radar observations may suffer from different sources of error, they may also be the quickest way to obtain a reliable estimate …

Wibasin: Basin Management Through An Integrated Platform, Xavier Llort, Rafael Sánchez-Diezma, David Sancho, Alvaro Rodríguez, Marc Berenguer, Daniel Sempere-Torres
International Conference on Hydroinformatics
A key issue in basin and dam management is the correct estimation of accumulated rainfall (observed as well as forecasted) over the catchment (over the characteristic concentration time for critical short-term management, and over longer time periods to anticipate rainfall situations). In this work we present a platform for basin and dam management, called WiBasin, which integrates different sources of precipitation (both observed and forecasted) in a continuous time series of hourly rainfall accumulation fields, having the best precipitation estimation available at each time step. Optimal rainfall estimates used for the past time steps are based on a geostatistical approach …

Hidromet: A Cloud-Based Ews Platform For Real Time Urban Flood Warning, Alvaro Rodríguez, Xavier Llort, David Sancho, Rafael Sánchez-Diezma, Ramon Bella, Vicente Gomez
International Conference on Hydroinformatics
Urban real time flood’s Early Warning Systems have been traditionally based on the use of punctual precipitation observations (raingauges) to model the sewer network’s behaviour by means of hydraulic models. Since a key issue in the EWS is the leadtime in detecting potential risks, Hidromet takes advantage of radar nowcasting techniques to feed a hydraulic model, not only with observed precipitation by raingauges, but also with forecasted precipitation for the following few hours. Radar nowcasting techniques allow forecasting the precipitation with a high degree of accuracy. This fact, together with the rapid update of the forecasts (typically around 10 minutes), …

Water Resources Policy Development Using Hydrologic And Systems Dynamics Modeling – A Case Study For East Africa, Lauren Gies, Buyung Agusdinata, Venkatesh Merwade
International Conference on Hydroinformatics
Drought is a natural disaster that affects millions of people across the globe. Lack of rainfall reduces crop yields and livestock productivity and in turn, food availability and income. In developing countries, these effects are even more detrimental. As droughts become more frequent, adaptation is a fundamental concern for countries and their policy makers. Hydrologic and system dynamics models were developed for a region in East Africa, focused on the Horn of Africa (ie. a region bordering Kenya, Somalia, and Ethiopia), an area well-known for frequent droughts due to unpredictable rainfall and high temperatures. The models simulate the interdependencies between …

Model Predictive Control For Real Time Operation Of Hydraulic Structures For Draining The Operational Area Of The Dutch Water Authority Noorderzijlvest, Jan Talsma, Dirk Schwanenberg, Jan Gooijer, Klaas-Jan Van Heeringen, Bernhard P. J. Becker
International Conference on Hydroinformatics
A pilot project in 2012 for the Dutch regional water authority Noorderzijlvest has shown that the application of Model Predictive Control (MPC) can increase the safety level of the water system during flood events by an anticipatory pre-release of water. Furthermore, energy costs of pumps can be reduced by making tactical use of the water storage and shifting pump activities during normal operating conditions to off-peak hours. In this paper, the extension of the pilot to a real time decision support system is presented. It supports the daily operation of 34 aggregated structures both in wet and dry periods by …

An Artificial Neural Network-Based Rainfall Runoff Model For Improved Drainage Network Modelling, David Walker, Edward C. Keedwell, Dragan A. Savić, Richard Kellagher
An Artificial Neural Network-Based Rainfall Runoff Model For Improved Drainage Network Modelling, David Walker, Edward C. Keedwell, Dragan A. Savić, Richard Kellagher
International Conference on Hydroinformatics
Modelling rainfall-runoff processes enables hydrologists to plan their response to flooding events. Urban drainage catchment modelling requires rainfall-runoff models as a prerequisite. In the UK, one of the main software tools used for drainage modelling is InfoWorks CS, based on relatively simple methods which are relatively robust in predicting runoff. This paper presents an alternative approach to modelling runoff that will allow for the complex inter-relation of runoff that occurs from impermeable areas, permeable areas, local surface storage and variation in rainfall induced infiltration. Apart from the uncertainties associated with the measurement of connected surfaces to the drainage system, the …
Reducing The Risk Of Floods In Urban Areas With Combined Inland-River System, Young-Il Moon, Jong-Suk Kim
Reducing The Risk Of Floods In Urban Areas With Combined Inland-River System, Young-Il Moon, Jong-Suk Kim
International Conference on Hydroinformatics
With the change of the water environment in accordance with climate change, the loss of lives and properties has increased due to urban flood. Although the importance of urban floods has been highlighted quickly, the construction of advancement technology of an urban drainage system combined with inland-river water and its relevant research has not been emphasized in Korea. In addition, without operation in consideration of combined inland-river water, it is difficult to prevent urban flooding effectively. This study, therefore, develops the uncertainty quantification technology of the risk-based water level and the assessment technology of a flood-risk region through a flooding …

Flooding in urban areas due to heavy rainfall coupled with high tides is a major concern affecting development of coastal cities all over the world. There is a spectrum of models such as 2D distributed flood models to simplified storage cell models using analytical expressions. All such models demand a high level of skill to handle geospatial data making it difficult for decision makers. Thus development of web GIS based hydrological application becomes essential. Traditionally, most web GIS based applications have used conceptual model because of low data requirements and parameter calibrations. In this paper web GIS based integrated flood …

Improvement Of The National Flood Early Warning System In Norway – Flood Level Warnings And Uncertainties, Péter Borsányi, Byman Hamududu, Sivachandran Navaratnam, Elin Langsholt
International Conference on Hydroinformatics
This work describes the methods and procedures applied to improve the national flood warning system in Norway by including water level forecasts at non-gauged but important locations and information on the corresponding uncertainty. In this approach, only a subset of model variables (inputs) and parameters are treated as uncertain. It is found that visualization of the forecasts is challenging, and therefore a number of experimental solutions are discussed.
Study On Optimization Of The Integrated Operation Of Dams Using Ensemble Prediction, Satoru Oishi, Hiroko Masuda
Study On Optimization Of The Integrated Operation Of Dams Using Ensemble Prediction, Satoru Oishi, Hiroko Masuda
International Conference on Hydroinformatics
Flood control is one of the most important issues of reservoir operation. Rivers in island countries like Japan, Philippines and Indonesia that have smaller reservoirs than continental countries needs short term reservoir operation for flood control. In Japan, typhoons give dominant amount of water to reservoirs. Pre-release of water which makes effective use of the capacity of a reservoir requires the rainfall amount forecast (hyetograph). Therefore, weather forecast of typhoons is indispensable for flood control. Masuda and Oishi (2013) developed the reservoir control operation model using stochastic dynamic programming with one week ensemble weather forecast. One week ensemble forecast consists …

This study proposes an alternative network relatively simple and inexpensive that can be used for maintaining communications capabilities during major natural disasters and other emergency situations by introducing a system that utilizes Short Message Service(SMS) over Wireless Mesh Sensor Networks(WMSNs). To create this WMSN we propose a system using the water level sensors widely used in rivers throughout the world. Nowadays, most of the communication systems and their applications require a network infrastructure like cellular network or the Internet for communications between users. This communication links can become unavailable during a major disaster due to damaged infrastructure and power outages. …

Flash floods often occurred suddenly and they also usually induce the occurrence of landslides and debris flows. The work of flash flood defense is full of challenge because of the complex process of flash flood formation. Disasters caused by flash flood occurred frequently and have an increasing trend in China with huge casualty. Therefore the Chinese government increased more inputs on the study of flash flood defense. After some endeavors in recent years, a set of non-structural measures on flash flood defense has been established featuring Chinese characteristics. In these measures, monitoring and warning system is a core. This paper …

Flood Alert System For Early Warning In Mountainous Coastal Watersheds: Coupling Data-Driven And Physically Based Hydrological Models, Javier Herrero, Zacarías Gulliver, María José Polo
International Conference on Hydroinformatics
Early warning systems are an essential tool for preventing flood risks and managing alert situations from real time data-driven outputs. In Mediterranean coastal regions, the response time is usually a constraint for decision-making since many watersheds have travel times of just a few hours from head sources to the floodplain in the valleys. In such situations, the anticipation of the alert situation in terms of probability occurrence is a key fact for managing alert conditions and mitigate flood consequences. Coupling data-driven forecasting with hydrological models may constitute a robust tool for alert assessment, provided that sound calibrations are available. This …
Comparison Of Ensemble Kalman Filtering And Particle Filtering On Short-Term Streamflow Forecasting Using A Distributed Hydrologic Model, Seong Jin Noh
International Conference on Hydroinformatics
Floods are the most common and widespread disasters in the world and are responsible for a greater number of damaging events than any other type of natural event. However, due to various uncertainties that originate from simulation models, observations, and forcing data, it is still insufficient to obtain accurate flood forecasting results with the required lead times. Recently, ensemble forecasting techniques based on data assimilation (DA) have become increasingly popular, due to their potential ability to explicitly handle the various sources of uncertainty in operational hydrological models. Difficulty lies in DA for flood forecasting because nonlinearity increases sharply during flood …

High-Resolution Flash Flood Forecasting For Large Urban Areas – Sensitivity To Scale Of Precipitation Input And Model Resolution, Dong-Jun Seo, Arezoo Rafieei Nasab, Behzad Nazari, Amir Norouzi, Thomas Mathew, Haonan Chen, V. Chandrasekar, Piraporn Jangyodsuk
International Conference on Hydroinformatics
Urban flash flooding is a serious problem in large, highly populated areas such as the Dallas-Fort Worth Metroplex (DFW). Being able to monitor and predict flash flooding at a high spatiotemporal resolution is critical to mitigating its threat and cost-effective emergency management. In general, the higher the resolution of the model and the precipitation input is, the better the spatiotemporal specificity of the model output is. Due to the errors in the precipitation input, model parameters and model itself, however, there are practical limits to the resolution of modeling. In this work, we assess the dependence of accuracy in streamflow …
