Water Resources Policy Development Using Hydrologic And Systems Dynamics Modeling – A Case Study For East Africa, Lauren Gies, Buyung Agusdinata, Venkatesh Merwade Aug 2014

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 …

Developing A Hydrologic Information System: Towards Promoting Sustainable Standardization, Abbas Fayad, Ibrahim Alameddine, Majdi Abou Najm, Mutasem El-Fadel

International Conference on Hydroinformatics

Water quantity and quality monitoring plays a key role towards the development of a sustainable water sector. The required infrastructure needed to monitor and manage surface and groundwater systems are often lacking particularly in developing countries. When available, water quantity and quality data are invariably fragmented, intermittent, not shared, with deficient metadata, and stored in formats that hinder establishing seamless coupling with hydrological models. Most data are saved locally with little attention placed on defining and maintaining metadata on the collection protocols, geographic referencing, measurement accuracy, resolution, detection limits, and data censorship. These limitations present serious challenges in reaching sound …

Rediscovering Manning’S Equation Using Genetic Programming, Carlos F. Gaitan Aug 2014

Rediscovering Manning’S Equation Using Genetic Programming, Carlos F. Gaitan

International Conference on Hydroinformatics

Open-channel hydraulics’ (OCH) research traditionally links empirical formulas to observational data. One of the most common equations in OCH is Manning’s formula for open channel flow (Q) driven by gravity (also known as the Gauckler-Manning-Strickler formula). The formula relates the cross-sectional average velocity (V=Q/A), the hydraulic radius (R), and the slope of the water surface (S) with a friction coefficient n, characteristic of the channel’s surface. Here we show a practical example where Genetic Programming (GP), a technique derived from Bioinformatics, can be used to derive an empirical relationship based on different synthetic datasets of the aforementioned parameters. Specifically, we …

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 …

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 …

Monitoring Snow Cover Area In Semiarid Regions Using Terrestrial Photography, Rafael Pimentel, María José Pérez-Palazón, Javier Herrero, María José Polo

International Conference on Hydroinformatics

The heterogeneous distribution of snow in mountain regions often constitutes a great problem for an adequate modeling of snow dynamics. Remote sensing is usually used for the detection of snow distribution, but the fixed spatiotemporal resolution of these sources greatly reduces their efficiency, especially when the significant scale of the process under study is smaller than the sensor resolution. This is the case of the snow in semiarid areas, where rapid snow melting on sunny and warm days may substantially change the snow cover within just a few days, or where small snow patches (O~1 m) usually persist during many …

Wrap Your Model!, Hauke Sonnenberg, Michael Rustler, Victor Philippon, Nicolas Caradot, Andreas Matzinger

International Conference on Hydroinformatics

Introduction Environmental models are often provided in the form of software solutions, with different levels of complexity. The simplest form is an executable file reading the model setup and boundary conditions from input files, doing the calculations and generating output files with model results. Preparing input files and reading output files requires to know and respect model specifics such as file formats and calling conventions. This "user-unfriendliness" may discourage the usage of models in this simplest form. However, these models may offer great opportunities since they are often freely available and contain the pure model "core" being fast in execution. …
