Regional Versus Physically-Based Methods For Flood Inundation Modelling In Data Scarce Areas: An Application To The Blue Nile, Kun Yan, Florian Pappenberger, Yakob M. Umer, Dimitri P. Solomatine, Giuliano Di Baldassarre
Regional Versus Physically-Based Methods For Flood Inundation Modelling In Data Scarce Areas: An Application To The Blue Nile, Kun Yan, Florian Pappenberger, Yakob M. Umer, Dimitri P. Solomatine, Giuliano Di Baldassarre
International Conference on Hydroinformatics
One of the main obstacles in mapping flood hazard in data scarce areas is the difficulty in estimating the design flood, i.e. river discharge corresponding to a given return period. This exercise can be carried out using regionalization techniques, which are based on flood data of regions with similar hydro-climatic conditions, or employing physically based model cascades. In this context, we compared the flood extents maps derived for a river reach of the Blue Nile following two alternative methods: i) regional envelope curve (REC), whereby design floods (e.g. 1-in-20 and 1-in-100 year flood peaks) are derived from African envelope curves …

Numerical Modeling Of Flow And Sediment Transport Within The Lower Reaches Of The Athabasca River: A Case Study, Shalini Kashyap, Ahmad Shakibaei, Ali Oveisy, Yonas Dibike, Terry Prowse, Droppo Ian
International Conference on Hydroinformatics
This study investigates flow and sediment transport patterns within the lower reaches of the Athabasca River (~250 km) in Alberta, Canada, which are characterized by complex bathymetry, regions of high tortuosity, and variable discharges and bed slopes. Sediment within this reach is primarily sand and gravel, but there is also a high percentage (>10%) of cohesive clay with unique settling properties. A combination of 1D and 2D regional numerical modeling is used here to predict hydrodynamics of the flow and transport of suspended sediment. Bathymetry measurements were obtained from a combination of high resolution 3D Geoswath and ADCP surveys, …

Statistically Downscaled North American Precipitation Using Support Vector Regression And The Big Brother Approach., Carlos F. Gaitan, Keith W. Dixon, Venkatramani Balaji, Renee Mcpherson
International Conference on Hydroinformatics
We implemented a hybrid downscaling model using classification and regression trees and support vector regression with evolutionary strategies to statistically downscale precipitation occurrences and amounts from 16 points across North America. All the selected points belong to different climate regions. In addition, to evaluate the downscaling model’s historical and future performances we used daily precipitation outputs (from a high resolution ~25km grid spacing global atmospheric model) as predictands, and coarsened versions of the same high-resolution outputs from the nearest nine gridpoints (interpolated to a ~100km grid), as predictors. This experimental setup, known as “Big-Brother” allows us to use the high-resolution …
Does The Risk Of Groundwater Depletion Drive Tube-Well Technology Adoption: A Case Of Pakistan, Arif Watto, Amin Mugera
Does The Risk Of Groundwater Depletion Drive Tube-Well Technology Adoption: A Case Of Pakistan, Arif Watto, Amin Mugera
International Conference on Hydroinformatics
We employ a moment-based approach to empirically analyse farmer’s decisions about adoption of tube-well technology under depleting groundwater resources using a farm level data from 200 farming households in the Punjab province, Pakistan. The results indicate that the higher the expected profit the greater the probability of adoption. Similarly, with increasing variance the probability of adopting tube-well increases significantly indicating that farmers choose to adopt tube-well technology in order to hedge against production risks. Statistical non-significant the third moment i.e., skewness indicates that farmer generally do not consider downside yield risk when decide to adopt tube-well technology whereas highly significant …

Model Configuration And Data Management In The Short-Term Water Information Forecasting Tools, Jean-Michel Perraud, James Bennett, David Robertson, Phil Ward
International Conference on Hydroinformatics
The Short-term Water Information and Forecasting Tools (SWIFT) is a suite of tools for flood and short-term streamflow forecasting, consisting of a collection of hydrologic model components and utilities. Catchments are modeled using conceptual subareas and a node-link structure for channel routing. The tools comprise modules for calibration, model state updating, output error correction, ensemble runs and data assimilation. Given the combinatorial nature of the modelling experiments and the sub-daily time steps typically used for simulations, the volume of model configurations and time series data is substantial and its management is not trivial. SWIFT is currently used mostly for research …

Bayesian Model Averaging Approach For Reducing Urban Flooding Damage Estimation Uncertainty, Vincenza Notaro, Chiara Maria Fontanazza, Gabriele Freni
International Conference on Hydroinformatics
Uncertainty analysis is useful to define the level of reliability of a modelling application, but operational methods are needed to identify the best modelling structure for a specific problem based on uncertainty reduction criteria. One interesting example is given by flood damage estimation problem where different possible modelling solution and flood damage estimation can be used depending on the case study. Past literature showed that several modelling structures may be equally reliable in terms of calibration ability but they may produce different uncertainty levels. The use of the Bayesian approach for uncertainty analysis has been stimulated by its rigorous theoretical …

Parameterization And Sampling Design For Water Distribution Networks Demand Calibration Using The Singular Value Decomposition: Application To A Real Network, Gerard Sanz, Ramon Perez
Parameterization And Sampling Design For Water Distribution Networks Demand Calibration Using The Singular Value Decomposition: Application To A Real Network, Gerard Sanz, Ramon Perez
International Conference on Hydroinformatics
The availability of a good hydraulic model increases the reliability of the results of methodologies using it. Thus the calibration of the model is a previous step that has to be done. The most uncertain parameters of the model are demands due to their constant variability. However, calibrating these demands requires a high computational cost that can be reduced by redefining the unknown parameters from demands to demand patterns. Besides, the number and location of the used sensors is highly correlated with the definition of such patterns. This paper presents a methodology for parameterizing and selecting sensors using the information …

Publishing And Federating Global Water Data And Maps Via Web Services, David K. Arctur, David R. Maidment
International Conference on Hydroinformatics
Finding and accessing data in most countries of the world about local, regional and national water resources (streamflow discharge, gauge depth, soil moisture, etc.) has been complicated by a number of issues, from concerns of local and national security, to lack of suitable conventions and standards for data exchange that could be reasonably implemented and enforced at the national and international levels. These issues are now starting to be addressed, thanks to recently adopted standards for hydrologic data exchange, and growing acceptance of community standards for web services to perform such data exchange. This presentation reviews recent work in this …

On The Modeling And Real-Time Control Of Urban Drainage Systems: A Survey, Luis Antonio Garcia Gutierrez, Eduardo Escobar, Duvan Téllez, Julian Barreiro Gómez, Nicanor Quijano Silva, Carlos Ocampo-Martinez
International Conference on Hydroinformatics
Drainage network are complex systems composed by several processes including recollection, transport, storing, wastewater and/or rain treatment, and return of the water to a receiving environment. Urban drainage systems (UDS) involve most of these processes inside cities and can be either separate or combined systems, depending on how wastewater and rainwater are managed. The way UDS manage the wastewater is through the convenient handling of active elements such as gates (redirection and/or retention), storing tanks and pumping stations, when needed. Therefore, the modeling and control of UDS basically consists in knowing and representing the (dynamical) behavior of those elements and …

Evaluating Climate Change Scenarios For Regional Hydrological Management In Mountainous Semi-Arid Environments, Agustín Millares, Javier Herrero, Cristina Aguilar, María José Polo
Evaluating Climate Change Scenarios For Regional Hydrological Management In Mountainous Semi-Arid Environments, Agustín Millares, Javier Herrero, Cristina Aguilar, María José Polo
International Conference on Hydroinformatics
Snow processes play a relevant role in semi-arid mountainous basins where snowmelt dynamics conditions the availability of water resources. In such environments, many rivers flow during the dry season due to the water storage in the snow cover while heavy rainfall events sporadically trigger severe flood events. These particularities confer to these areas special interest due to their high sensitivity in the hydrological response against changes in the meteorological conditions. This issue could be critical in many regions of the world linked to semi-arid mountain areas (e.g., the Atlas Mountains, Andean Cordillera,…) and presents a real challenge for future modifications …

Levels Of Data Interoperability In The Emerging North American Groundwater Data Network, Boyan Brodaric, Nate Booth, Eric Boisvert, Jessica Lucido
International Conference on Hydroinformatics
The Canadian Groundwater Information Network (GIN) and the US National Ground-Water Monitoring Network (NGWMN) connect data from a variety of sources including states, provinces and federal agencies. Data heterogeneity is a major challenge faced by these networks, one that must be overcome at five distinct levels: systems, syntax, structure, semantics, and pragmatics. This paper discusses approaches taken at each of the five levels to ensure interoperability between the Canadian and American networks. The result is an emerging North American Groundwater Data Network, which enables users to access data transparently and uniformly on either side of the shared border.
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
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 …

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 …

International Conference on Hydroinformatics
Accurate simulation of the sediment processes at the vicinity of the sediment bed/water interface is still very difficult because of the multi-physic character of the problem. A soil is a continuum and porous media having solid properties such as elasticity and plasticity. It is usually considered as impermeable boundary which could evolve through erosion and deposition fluxes. Flow characteristics close to the liquid-bed interface are poorly described by soil mechanics and rheological characteristics of the soil are usually neglected by fluid mechanics. In order to account for the flow domain as a whole, extending from the substratum up to the …

Application Of Data Mining For Reverse Osmosis Process In Seawater Desalination, Jaewuk Koo, Yonghyun Shin, Sangho Lee, Juneseok Choi
International Conference on Hydroinformatics
Reverse osmosis (RO) membrane process has been considered a promising technology for water treatment and desalination. However, it is difficult to predict the performance of pilot- or full-scale RO systems because numerous factors are involved in RO performance, including variations in feed water (quantity, quality, temperature, etc), membrane fouling, and time-dependent changes (deteriorations). Accordingly, this study intended to develop a practical approach for the analysis of operation data in pilot-scale reverse osmosis (RO) processes. Novel techniques such as artificial neural network (ANN) and genetic programming (GP) technique were applied to correlate key operating parameters and RO permeability statistically. The ANN …

A Cascade Of Models To Guide Reservoir Operations: Application On The Deadwood River System, Idaho, Usa, Andrew W. Tranmer, Daniele Tonina, Peter Goodwin, Rohan Benjankar, Matthew G. Tiedemann, Paul Woods
International Conference on Hydroinformatics
Adaptive management strategies are increasingly being used by resource managers to optimize complex water delivery systems at the scale of entire watersheds. A variety of models have been proposed to evaluate systems in a piecemeal approach that often times operate at different spatial and temporal scales and prove difficult to integrate with associated field data. In the Deadwood River system of Central Idaho, a series of cascading models was utilized to examine potential impacts of reservoir operations on endangered resident bull trout. Results from integrating limnologic, temperature, nutrient, hyporheic, and hydraulic models show that reservoir operations must remain dynamic depending …

Evaluating Alternative Water Allocation Policies Among Competing Users In Bow River Basin, Alberta, Canada, Wei Xu, Nader Khoshroo, Henning Bjornlund
International Conference on Hydroinformatics
Demand for water from rivers and aquifers for consumptive use has grown greatly due to population and economic growth and changing lifestyle and dietary habits. Consequently, aquatic ecosystems, especially in semi-arid and arid regions across the world, suffer adverse environmental impacts of over-extraction. Historically, Alberta’s water allocation system has been based on the first-in-time-first-in-right (FITFIR) system, granting the preference to the licensees based on the seniority of their licenses. In recent years, scientists, policy makers, and water users have raised questions whether FITFIR will continue to be the most appropriate allocation system to manage increasing scarce water resources in Alberta. …

International Conference on Hydroinformatics
This paper describes a hydroinformatic model for generating a Pareto set of LNG terminal layouts that are subject to uncertainty using a multi-objective genetic algorithm. The NSGAII is used to select parameters that propagate through a bespoke LNG terminal design algorithm which includes a Monte Carlo simulator to estimate the uncertainty in each concept. This allows the trade-off between cost and risk to be explored at the earliest stage of design. The results of a case study indicate that nearshore terminals typically have lower capital costs but higher maintenance costs and more uncertainty. The paper concludes that in the example …

Effects Of 2d And 1d Modeling On Mapping Aquatic Habitat Quality, Rohan Benjankar, Daniele Tonina, Jim Mckean
International Conference on Hydroinformatics
The distribution of aquatic habitat at the organism scale, i.e. 1 by 1m or smaller is typically predicted from local physical characteristics of stream flow, bed, banks and sediment characteristics and a set of biological preference curves. The flow properties are typically predicted with numerical modeling whereas stream bed and bank characteristics defined from interpolated DEM generated by topographical surveys and field observations. Information on the effects of flow properties and streambed morphology due to numerical modeling dimensionality on aquatic habitat modeling is limited. Two-dimensional (2D) modeling is becoming the most popular method to map micro-habitat but its application is …

Many hydrologic modelers around the world use Soil Water Assessment and Tool (SWAT) to simulate hydrologic processes, water quality loadings and testing agricultural management scenarios. Once these tasks are complete including publication of results, the models generally are not published or made available to the public for further use and improvement. Although publication or sharing of models is not required for journal publications, sharing of models may open doors for new collaborations, and avoids duplication of efforts if other researchers are interested in simulating a particular watershed for which a model already exists. For researchers, who are interested in sharing …
