Water resource planning and optimizing it using vensim model

Regarding development in human population as well as the advances of industries and agriculture in the modern world increasingly need for water supply is unavoidable.
Furthermore, restrictions in water resources and sustainable water management have made it almost impossible for us to fulfill all the needs for water demand. Thus toprovide and highly ensure water supply in terms of priorities such as domestic,
agricultural rights, environment, industry and agricultural development, we need a precise and careful planning. In order to optimize the planning, in this study we tried to
model the Finesk proposed dam and its watershed by using VENSIM casual model.
VENSIM is visual model that can depict, simulate, analyze and optimize a system's dynamic models. In this regard first, stream flow regime and existed water resources inupstream and downstream was determined. Then demands and consumptions were evaluated and finally according to physical dimension of Finesk propose dam, the
casual model in VENSIM was created. With considering Ten different plans, the result showed that the optimum condition to satisfy demands, in term of priorities in downstream can be provided by allocating ٨__٧ MCM for domestic purposes, ٣___
MCM for environment aims and ٠_٨١٢ MCM for agricultural rights.
