Research On Watershed Simulation System Based On Simulator Technology

Watershed is an enormous system with extremely complex interior operation mechanism, in which the key factor is the water system. Description and analysis of water cycling system becomes the key content in watershed issues, such as flood controlling, environment impacting, water resources planning, soil and water conservancy etc. One of main outputs of those researches is the water cycling simulation model. With the developement of simulation technology, there are many higher requirements advanced which mainly concentrated in three aspects: reliability, efficiency and capability. The key to meet these requirements is to improve the reusability of the model software. Based on the modern simulation theory, this paper analyzed characteristics of watershed system and disassembled the watershed into functional components. Then, using the newest reusable component technology , describe and design each of them as basic watershed modules, namely watershed simulators. Further more, in accordance with the topological theory and flexible system technology, a flexible construction method was presented and used to assemble those simulators into a watershed simulation system. This flexible simulators-based watershed simulation environment provides tools with well applicability, expansibility, integration capability which can make the development of watershed simulation system simply and efficiently.
