Spatial and Temporal Water Allocation in the Kissimmee

In many areas of the country, there is strong project area change. To improve the system of water competition among agricultural, municipal, industrial management so it could better satisfy various users of and other users of water. Water managers are faced the system, the Flood Control District undertook a with the problem of allocating available water among research and development approach to adapt mathealternative uses. matical modeling techniques to its system [15]. Their The study [11] upon which this paper is based goal has been to develop: (1) a physical systems was a cooperative effort with the Central and model, (2) rainfall prediction model and (3) allocaSouthern Florida Control District which is typical of tion model. The District's efforts in physical system many water management districts making decisions modeling and rainfall prediction models have been regarding allocation of a limited amount of water reported elsewhere [12, 13, 14]. The study upon among uses and users. When the District was formed, which this paper is based was directed toward the it was developed with emphasis on facilities to development of allocation models. provide relief from flooding.
