Decision Support Systems in Water Resources Management

The reservoir water level is controlled by dam gates. If water comes to a reservoir in huge quantity more than its full capacity then the gates are required to be opened. But if water is less then gates are closed to store water for future use. Some questions are always there in front of decision makers and dam engineers such as how to decide whether to open or close the dam gates. A solution of above problems needs a dedicated program based on Intelligent Decision Support System (DSS) using latest IT tools to decide that how much quantity of water is reaching to the reservoir in advance in the event of rainfall upstream and in what period, so accordingly Dam gates could be managed. In an absence of such type of program, floods are damaging the property year after year. For management of dam efficiently, it requires taking fast and precise decisions after analyzing available data and making predictions so that flood situation can be avoided. It should be flexible enough and able to handle water level in the reservoir and Gate management efficiently.

The decision support system (DSS) for water resources planning and management is the tool to have better understanding on the nature of water resources circumstances in association with the intentions set up for the best possible benefit of human and for sustainable environment. The decision support tool would provide the decision-makers with interactively exploratory mechanism for designing and analysing the interrelated decision situations to be able to formulate the best possible choices. In general, the decision support system consists of three most important components. These are database, computer model, and user interface method (windows and geographic information system). In more specific application, the DSS for water resources planning and management are frequently categorized into a number of classifications. These are among others: DSS for water allocation and distribution; flood mitigation; water quality and environment management; rivers and river infrastructure maintenance; spatial planning; programming and budgeting; and for research and development implementation. This paper presents an overview decision support system for water resources planning and management in Indonesia, concepts and its implementation in several projects and agencies in Indonesia. The approach employed is based on the analysis of the data and information requirement and incorporating them with the fundamental procedures for making use of the decision support system. Considering the present status, issues, problems and constraints of water resources in Indonesia, it is considerably realistic to recommend the application of the concept of DSS for water resources planning and management. These include the comprehensive identification of the current status and state of affairs of water resources, as well as availability of database, technical models and the subsequent application of research and development measures to improve the decision support system on self-reliance human resources basis.

We describe our work in developing decision support tools to manage large international rivers. This is a complex environmental decision making problem due to the presence of multiple objectives stemming from multiple uses of the reservoirs (energy production, irrigation, flood protection,

According to the European Water Framework Directive 2000/60/EC, all member states must formulate and implement Integrated River Basin Management (IRBM) strategies. Water resources management is not a straightforward task not only due to computational limits in modelling, but also due to the multiple interdependent processes (physical, biochemical, ecological, social, legal and political) that govern the behaviour of water resource systems. These processes are affected by uncertainties and by the unpredictable actions of multiple individuals and institutions involved in the management and operation of such systems. The Decision Support Systems (DSS) for River Basin Management (RBM) enable the comparison of water strategies for different scenarios based on the effects of multiple objectives. They can be used to support the planning and implementation of measures, as well as the communication between public authorities and other public or private stakeholders. The present paper aims to...

The paper describes recent results achieved in the project AQUIN which purpose is to investigate possibilities of controlling certain complex water management situations. The research has been initiated by a practical problem related to water consumption from the river Uhlava in the Western part of the Czech Republic. On the river, there is a reservoir Nyrsko situated 95 km upstream from the consumption place in the town Plzen. It is a multipurpose drinking-water reservoir, especially used for compensation and also for energy production. Until now, flow deficiency in the consumption place was solved by over quantity of water discharge experimentally. A knowledge-based decision support system, which is being developed recently in the scope of the project, will be able to find really suitable and economically endurable manipulations in Nyrsko reservoir to reduce unused river-flows in water consumption place Plzen during dry periods. The paper is devoted to a brief presentation of the problem solved, followed by a description of the solution, which is being developed in the scope of the AQUIN project. An analysis of information and knowledge sources about the river Uhlava and its characteristics has been performed and the suitable knowledge has been codified, organized and stored in an appropriate knowledge repository. This repository serves as a basis for a knowledge-based part of the decision support system, helping the river basin operators and dispatchers to create as accurate decisions as possible. The draft architecture of the system and some details about its implementation will be presented.

Abstract: Decision Support Systems (DSS) comprise a wide-range of computer-enabled applications that are based on some form of analytical model, commonly linked to a database. Coupled with the visualization and spatial analysis facilities provided by a Geographic Information System (GIS), a unifying framework can be developed to promote the uptake of advanced decision support technology across a wide range of stakeholders. This paper describes an architecture for a Decision Support Workbench to facilitate the ...

The GESREAU project (GEStion des Ressources en EAU) aims to define a new relevant concept for global and integrated water management adapted to administrations. This globalized approach intends to handle problems at various scales in its geographical context, to understand the dynamics of the system, and to go beyond the traditional administrative approach, which is very sectorrelated. The integrated proposal requires better communication between the various water management specialists concerned by flood, drought and resources, quality and fauna preservation, and the public domain of the river network. These two aims demand the use of data processing and analysis systems such as Database Management Systems, Geographic Information Systems, simulation models, etc that are gathered in a Decision Support System. The components of the DSS have to suit the responsibilities and the capabilities of the administration, as well as the different levels of land documentation.

The new Brazilian water resource policy brought an innovation in the management, organizing and planning of water use in river basins, especially the instruments provided for its implementation, as the water right. During the decision process, the water manager may select the best alternative for a use or effluent discharge, so he must access information related to water resources and environmental issues, which are usually scattered among the environmental public services. Gathering such knowledge becomes a complex task that often does not allow the access to complete data. Thus, it is important to design a computational tool that can aggregate all necessary information to the water manager during the decision process, such as the issue of authorization. This paper presents a generic decision support system for water resource management called SAD-RH, developed in Delphi programming language. The system has layers containing relevant factors, such as: hydrographs, vegetation, conse...
