Gis-Based Site Selection For Agricultural Irrigation With Reclaimed Water, Natalia Sardinha, Antonio Albuquerque, Flora Silva, Paulo Scalize
International Conference on Hydroinformatics
The reclaimed water produced in an urban wastewater treatment plants (WWTP ) seems to be suitable for agricultural irrigation. The selection of agricultural parcels for its application requires the collection and analysis of complex information (e.g. characteristics of the reclaimed water, soils characteristics, type of crop production and maximum needs of water and nutrients, land use, environmental and legal restrictions) and GIS tools for georeferentiation complex information and multi-criteria analysis. The main objective of the study was to identify the suitable agricultural parcels for irrigation with reclaimed water, taking into account its characteristics, the type and needs of the dominant …
Modeling Of District Metered Areas With Relatively High Leakage Rate. The Case Study Of Kalipoli’S Dma, Antonios Bakogiannis, Athanasios Tzamtzis
Modeling Of District Metered Areas With Relatively High Leakage Rate. The Case Study Of Kalipoli’S Dma, Antonios Bakogiannis, Athanasios Tzamtzis
International Conference on Hydroinformatics
The article reviews the modelling of District Metered Areas (DMAs) with relatively high leakage rate. As a generally recognised approach in modelling of leakage does not exist, modelling of leakage by enginners and other researchers usually takes place by dividing the whole leakage rate evenly to all available nodes of the model. In this article, a new methodology is proposed to determine the nodal leakage by using a hydraulic model. The proposed methodology takes into consideration the IWA water balance methodology, the Minimum Night Flow (MNF) analysis, the number of connections related to each node and the marerial of pipes. …

Reliability Of Simulated Discharges For Different Gauge Locations In A Semi Distributed Rainfall Runoff Model, Johannes Bellinger, Stefan Achleitner, Johannes Schöber, Friedrich Schöberl
International Conference on Hydroinformatics
In terms of flood forecasting in alpine environments, predictions at different gauges as well as sites with exposed infrastructure within the catchment are required. The used semi-distributed hydrological model HQsim combines runoff formation and surface runoff routines with an implemented channel routing for river reaches. This allows the estimation of discharges at selected channel segments. As a case study a large alpine catchment with a size of 890 km² is used. The uncertainty in the discharge prediction is investigated at three discharge gauges located along the main river. The basis of our experimental set-up are 15,000 samples describing the prior …
Distribution Of Hydrological Losses For Varying Rainfall And Antecedent Wetness Conditions, Sithara H P Walpita Gamage, Guna Hewa, Simon Beecham
Distribution Of Hydrological Losses For Varying Rainfall And Antecedent Wetness Conditions, Sithara H P Walpita Gamage, Guna Hewa, Simon Beecham
International Conference on Hydroinformatics
Hydrological loss is a vital component in many hydrological models, which are usedin forecasting floods and evaluating water resources for both surface and subsurface flows. Due to the complex and random nature of the rainfall runoff process, hydrological losses are not yet fully understood. Consequently, practitioners often use representative values of the losses for design applications such as rainfall-runoff modelling which has led to inaccurate quantification of water quantities in the resulting applications. The existing hydrological loss models must be revisited and modellers should be encouraged to utilise other available data sets. This study is based on three unregulated catchments …
Improving Sediment Transport Modelling By A Combination Of Field Data And Sensitivity Analysis, Tom Vanwalleghem, Juan Pablo Garcia, Juan Vicente Giráldez
Improving Sediment Transport Modelling By A Combination Of Field Data And Sensitivity Analysis, Tom Vanwalleghem, Juan Pablo Garcia, Juan Vicente Giráldez
International Conference on Hydroinformatics
Traditionally, the relationship between flow rate and sediment concentration in rivers has been estimated empirically. However, the problem of empirical data collection is that it is often difficult to cover the entire range of flow rates. Especially higher flow rates are often undersampled, which might lead to an underestimation of modelled sediment transport as flood events are often associated with important erosion events. In order to overcome this limitation, the introduction of the transport capacity concept can establish a safe upper bound of this sediment transport relationship. Nevertheless, given the number of implied variables in this equation, there is a …

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 …

Simulation Of Shoreline Changes Along Muthalapozhy Harbour, India, Dhyan Singh Arya, Santosh Kori, A M. Vaidya
International Conference on Hydroinformatics
A study of Muthalapozhy fishing harbour, located in south India, was conducted for simulating shoreline changes using LITPACK modelling tool. The analysis shows that the estimated advancement in shoreline is of the order of 45 m/year initially, which gradually reduces to 25 m/year. It was also found that the coastline advances more during the south-west monsoon (i.e. June to September) season. Simulation of breakwaters shows that the length of the breakwater should be increased by 200 m for south breakwater and 70 m for north breakwater to keep the channel operational without dredging till 2016. The results of the simulated …

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
Estuaries play an important role in exchanging water and providing a navigational pathway for ships. These zones are very sensitive and vulnerable to any interventions in coastal dynamics. Almost major of these inlets experience coastal problems such as severe erosion, and accretion. Rosetta promontory is an example of this environment. It suffers from many coastal problems as erosion problem along the coastline and siltation problem inside the inlet. It is due to lack of water and sediment resources as a side effect of constructing the Aswan High dam. The shoaling of the inlet leads to hindering the navigation process of …

Integration Of Trmm Rainfall In Numerical Model For Pesticide Prediction In Subtropical Climate, Manika Gupta, N.K. Garg, Prashant K. Srivastava, Tanvir Islam
International Conference on Hydroinformatics
Rain gauge data in developing countries are usually very limited, which constrains most of the hydrological modelling applications. The satellite based rainfall estimates could be a promising choice and hence can be used as a surrogate to ground-based rainfall. However, the usefulness of these products needs to be evaluated for hydrological application such as for pesticide predictions. The present study compares the contaminant transport simulation with the utilization of Tropical Rainfall Measuring Mission (TRMM) rainfall compared with rain gauge data from the field site. Through this study, transport trends of the pesticide, Thiram, a dithiocarbamate, at different time and depth …

Eco-Hydrological Process Simulations Within An Integrated Surface Water-Groundwater Model, Michael Brian Butts, Maria Loinaz, Roberta Serena Blasone, Peter Bauer-Gottwein, Flemming Thorbjørm Hansen, Birgitte Von Christierson, Jannick Kolbjoern Jensen, Jane Bang Poulsen
International Conference on Hydroinformatics
There are several key modelling challenges in addressing the complementary requirements of the Water Framework Directive and the Groundwater Directive. The first is to consider groundwater, surface water, water quality and ecosystems as an integrated system and develop modelling tools capable of representing these interactions. For example, the restoration of wetlands often requires an understanding of the interaction of surface water and groundwater quantity and quality. Secondly while static indicator-based or statistical approaches are widely used for overall management, the actual ecosystem is highly dynamic and both the actual response to different threats and impact of measures will also be …

Numerical Modeling Of Otec Thermal Discharges In Coastal Waters, Jongkyu Kim, Hyeon-Ju Kim
International Conference on Hydroinformatics
Thermal discharge from industrial outfalls is categorized into two major classes based on their density. First class is the effluent that has a higher density than that of the ambient water body. The second class is the effluent that has a lower density than that of the ambient water body. Due to the effect of several factors such as tides, waves, winds, river discharges, thermal effluents etc., the mixing characteristics of OTEC (Ocean Thermal Energy Conversion) thermal plume is much complicated. In this study we try to identify the mixing and dispersion characteristics of coastal waters to consider their physical …

Meteomap: Generation Of Meteorological Variables For Distributed Physically-Based Hydrological Modeling, Cristina Aguilar, Javier Herrero, Agustín Millares, Miguel A. Losada, María José Polo
International Conference on Hydroinformatics
Distributed energy and water balance models require time-series surfaces of the meteorological variables involved in hydrological processes. Most of the hydrological GIS-based models apply simple interpolation techniques to extrapolate the point scale values registered at weather stations at a watershed scale. In mountainous areas, where the monitoring network ineffectively covers the complex terrain heterogeneity, simple geostatistical methods for spatial interpolation are not always representative enough, and algorithms that explicitly or implicitly account for the features creating strong local gradients in the meteorological variables must be applied. Originally developed as a meteorological pre-processing tool for a complete hydrological model (WiMMed), MeteoMap …

Modelling Of Thermal Energy Balance In Sewer Systems, Jan Hofman, Martin Bloemendal, Bas Wols, Claudia Agudelo-Vera, Jorge Elias Maxil, Pascal Boderie, Mark Nijman, Jan Peter Van Der Hoek
International Conference on Hydroinformatics
Warm water is an important factor in the water and energy nexus. The energy used to produce warm tap water is often 10 times higher than the operational energy to produce and distribute drinking water and to collect and treat wastewater together. Once used in a shower, bath or laundry machine, the hot water is disposed into the sewer system. For modern homes in The Netherlands this is 30-50 % of the total heat loss. Heat recovery from sewer systems may therefore be an interesting option to reduce water use related energy. In this study a model was developed to …

Development Of A Stormwater Low Impact Development Planning Tool For The Province Of Ontario, Canada, James Li, Zhi Zheng
International Conference on Hydroinformatics
Stormwater low impact development practices (LID) are lot-level measures which reduce runoff from lots and roads. Although there are many LID planning tools available (ranging from watershed, city, and site levels), it is not easy to find one that is appropriate for development of a LID site plan in Ontario. In particular, the Province of Ontario’s LID performance requirements are based on long-term average annual runoff and pollutant loading reduction. After a review of 16 LID planning tools in North America, it was found that 70% of these tools are site or city level and outputs from these tools include …
