Development Of A Decision Support System (Elmaadss) For The Integrated Water Management Of Mediterranean Phosphate Mining Areas, Soulis Konstantinos, Nicholas Dercas, Bru Kathy, Graveline Nina, Angeliki Stefopoulou
International Congress on Environmental Modelling and Software
The phosphate industry is a major contributor to the economy of many South Mediterranean countries. Large volumes of water are required by the mining industry in areas where water resources are scarce. The integrated management of water in the influence zone of phosphate mines with due respect to other sectors of the economy and populations is a way to further develop these regions. To achieve this objective, the implementation of a Decision Support System constitutes an innovative tool, which offers an integral view of water management in the phosphate mining areas and gives an overview of the interconnections and interactions …

Development Of A Dss For The Generation Of Wwtp Configuration Alternatives, M. Garrido, A. Riu, Xavier Flores-Alsina, Ignasi Rodríguez-Roda, Manel Poch
International Congress on Environmental Modelling and Software
The objective of this paper is to present the development of a decision support system (DSS) that generates flow diagrams in wastewater treatment plants (WWTP). The proposed DSS is based on a hierarchical decision approach that breaks down a complex design problem into a series of issues easier to analyze and to evaluate. For each one of these issues, three levels of abstraction are defined (units, submeta-units and meta-units) modifying their degree of engineering detail and thus facilitating the decision maker being focused at each design step. The generation of the flow diagrams is carried out by means of the …

International Congress on Environmental Modelling and Software
China’s gross installed hydropower generating capacity has surged 500% since 1980 and exceeded 100 GW in 2004, making up one quarter of gross installed electric power capacity and providing about e 20 percent of the country’s total electric power. China’s hydropower system, after nearly 20 years development, has formed a trans-basin, large-scale hydropower stations operation system, with complex scheduling relations and requiring a variety of methods and techniques to solve. One of the biggest challenges facing power grids of China today is how to construct a large scale operation hydropower system which is scientific, efficient, convenient, and available for practical …
Intercomparison Of Generic Simulation Models For Water Resource Systems, Giovanni M. Sechi, Andrea Sulis
Intercomparison Of Generic Simulation Models For Water Resource Systems, Giovanni M. Sechi, Andrea Sulis
International Congress on Environmental Modelling and Software
Particularly in water resource systems that frequently experience severe droughtevents, generic simulation models provide useful information for the definition of droughtmitigation measures. Among them, AQUATOOL (Valencia Polytechnic University),MODSIM (Colorado State University), RIBASIM (DELTARES), WARGI-SIM(University of Cagliari) and WEAP (Stockholm Environmental Institute) are hereconsidered for the preliminary analysis of alternative plans and policies. This paper is aboutmodelling in practice more than in theory: the emphasis is on the application of thesesimulation models to a multireservoir and multiuse water system in Southern Italy wherefrequent droughts in the last two decades have required the adoption of unsustainabletemporary user-supply restrictions. While each model has …

Simulating The Thames Water Resource System Using Iras-2010, Evgenii S. Matrosov, Julien J. Harou
International Congress on Environmental Modelling and Software
The Interactive River-Aquifer Simulation 2010 (IRAS-2010) is a computationally efficient open-source water resource management simulation computer program. Given hydrological inflows, evaporation rates, water allocation and reservoir release rules, consumptive water demands and minimum flows, IRAS-2010 estimates flows and storages throughout the node-link water resource network at each time period. The program is an updated version of a code originally developed at Cornell University. It now links to a generic customizable user-interface for water models called HydroPlatform. This paper briefly describes IRAS-2010 then describes an application of IRAS-2010 to the Thames river system (UK). The system is simulated weekly over an …
Integration Of Mathematical Models In A Decision Support System For Control Of Priority Pollutants In Urban Catchments, Natasa Atanasova, Matej Cerk, Primoz Banovec, Mateja Skerjanec, Webbey De Keyser, Lorenzo Benedetti
Integration Of Mathematical Models In A Decision Support System For Control Of Priority Pollutants In Urban Catchments, Natasa Atanasova, Matej Cerk, Primoz Banovec, Mateja Skerjanec, Webbey De Keyser, Lorenzo Benedetti
International Congress on Environmental Modelling and Software
A decision support system (DSS) for systematic control of priority pollutants (PP) sources, based on economic activities and production (release) processes in urban catchments was recently developed. One of the crucial functionalities of the DSS is evaluation of source control measures, which is based on mathematical models, used for simulating the fate of the PPs in urban catchments under different conditions. This work presents a methodology for efficiently building and integrating dynamic mathematical models into the DSS. A combination of two modelling approaches is proposed: empirical or data-driven and mechanistic or knowledge-driven. Data-driven methods, particularly those from the area of …

International Congress on Environmental Modelling and Software
The objective of the paper is to evaluate the applied non-standardised Model Requirement Analysis (MRA). Using the presented methods and results of the MRA, we discuss the suitability for appropriate ways to improve applied methods using the example of the Sustainability Impact Assessment Tools (SIAT). Special focus is given to the prerequisites of project design to assure model use towards model outcome. The applied methods of the MRA consist of evolutionary prototyping, which provides a way to structure the subsequent group discussions with end-users. The results first summarise the conducted interactions with potential end-users and evaluate the usefulness of conducting …

An Approach To Water Supply Clusters By Semi-Supervised Learning, M. Herrera, S. Canu, A. Karatzoglou, Rafael Pérez-García, Joaquín Izquierdo
International Congress on Environmental Modelling and Software
The rational distribution of water in a water supply network (WSN) is a complex problem, especially for systems of large scale. Its complexity is continually increasing from the point of view of technical management. The division of WSN into hydraulic zones is a partition of the supply network into subsystems with controlled inputs and outputs, building smaller independent networks. This solution is a strategic option used in many cities worldwide to control and operate their systems seeking to improve the WSN management, working with each part as a whole. Looking for leaks, detecting water distribution anomalies or carrying out rehabilitation …

International Congress on Environmental Modelling and Software
Water management models that lack a user interface, data management, reporting and visualization capabilities are less likely to make an impact on real world water systems. Model platforms can improve this situation; they allow researchers and model developers to link model codes to a generic user interface and data management system. We present an open-source model platform for network-based models called HydroPlatform. The platform links users and their data to water management models through generic import/export functions or custom add-ins. This paper focuses on export functionality, and specifically on a link to the Generalized Algebraic Modeling System (GAMS). HydroPlatform is …

The USDA-ARS Agricultural Systems Research Unit (ASRU), in a collaborative effort with Colorado State University (CSU), developed the Great Plains Framework for Agricultural Resource Management (GPFARM) DSS. The general purpose of GPFARM is to serve as a whole-farm/ranch DSS for strategic agroecosystem sustainability evaluation across the U.S. Great Plains. Despite a reasonable level of producer involvement in the requirements analysis, development, and evaluation phases of GPFARM, it can be argued that the rate of adoption has been slow compared with the rate predicted at the initial development stage. In this paper, we provide a brief overview of the GPFARM DSS. …

International Congress on Environmental Modelling and Software
Nowadays there is new and stronger evidence that sea level rise, increased storminess and coastal erosion as a consequence of global warming are likely to have profound impacts on coastal communities and ecosystems. Regional Risk Assessment (RRA) is an interdisciplinary approach to evaluate and rank potential impacts, targets and areas at risk from climate change hazards. Within the Euro-Mediterranean Centre for Climate Change (CMCC) a RRA methodology was developed to assess impacts of climate change at the regional scale and to assist coastal communities in planning adaptation measures. The proposed methodology integrates the output of downscaled climate, circulation, morphodynamic and …

Development And Validation Of A Decision Support System For The Integrated Operation Of Membrane Bioreactors, Joaquim Comas, Hèctor Monclús, Giuliana Ferrero, Ignasi Rodríguez-Roda, Luis Sancho, Eduardo Ayesa
International Congress on Environmental Modelling and Software
Membrane bioreactor technology in wastewater treatment and re-use is currently challenging traditional wastewater methods. However, although this technology presents many advantages as in most membrane filtration processes the permeate flux and permeability declines during filtration due to membrane fouling. Therefore controlling membrane fouling is the key issue in MBR operation. Nevertheless, membrane fouling is a very complicated phenomenon that results from multiple causes. Thus an intelligent Decision Support System for the integrated operation of membrane bioreactors has been developed. This Decision Support System, based on empiric and heuristic knowledge, gathers on-line and off-line information about both the biological and physical …
