| Abstract | Proper allocation of water among several competing users becomes necessary if the available water is scarce. In such cases it is very difficult to express the water management goals of a complex situation as a single objective when the available resources are scarce compared to the demand. In such cases proper sharing of water among competing users becomes necessary. The present study attempts to develop an integrated water allocation model (IWAM), which can assist decision makers and operators in optimally allocating limited water supply from a source (such as storage reservoir) to different user sectors taking into consideration the socio-economic, environmental and technical aspects. The IWAM, a deterministic user-friendly interactive model is developed using Microsoft Excel in the Windows operating system using the Visual Basic language. IWAM comprises a reservoir operation model and a water allocation model, which is based on the multiobjective decision making approach. Industry, hydropower, agriculture, domestic, environment and recreation are the six different water use sectors considered in the model. The model considers two objectives functions for optimizing the allocation of water: maximization of the satisfaction among various water use sectors (rational utilization of the resources) and maximization of the net economic benefit. The model satisfies the constraints such as minimum downstream flow requirement, minimum hydropower demand, controls flood, and others as defined by the model user. The model utilizes various data to find out the net economic benefit of the unit volume of water in different sectors needed for allocation. Weighting Technique (WT) and Simultaneous Compromise Constraint (SICCON) Technique have been used to optimize the allocation of the resources. The applicability of the IWAM model is demonstrated using a hypothetical case considering six different water use sectors with several possible scenarios and situations. |
