A Water Resource Allocation And Management Information Platform Based On Rainfall Runoff Simulation

Water resource is the water which located in the earth’s surface and could be used by human livings. When the waste and pollution problems of water resource is becoming more and more serious and could not be ignored, the importance and precious of water resources is self-evident. In this background, our government is putting forward the severest water resources management policy. The core concept of the policy is to hold the three red line,which including the red line of the development and utilization of water resources, the red line of water efficiency control, the red line of water pollutant limits in a water function area. According the core concept, the techniques in subtly information collection, data processing, the accurate prediction, dynamic simulation and optimization have become necessary conditions for implementing the severest water resource management. However, the implementation of these refinement technical means, should be supported by management information system, at the same time, must also introduced the geographic information system, as the distribution of water resources is closely related to the spatial position. In addition, the hydrology and water resources allocation model must be introduced into the integrated information platform, because the surface hydrological process or the optimal allocation of water resources can not realize just only rely on the management information system or geographic information systems. The function and technology which used to realize the water resources management gathered together to form a comprehensive information platform, according to the concept, the topic of this article is intended to be research and development of the integrated information platform which oriented the severest water resource management.Hutubi irrigation area is located in the southern margin of the Junggar basin which is a northwest inland area in of our country, and its northern is neighbor to Gurbantunggut Desert. The evaporation of Hutubi irrigation area is nearly 4 times of rainfall, and means it is a typical inland arid area. However, there are large demand on water resource, including the daily water, agricultural water and ecological water consumption, as there are a large number of residents, livestock and arable land in the irrigation area. Which made Hutubi irrigation area become the important research area in to implement the severest water resources management is the contradiction between natural condition and social. We take the the Hutubi irrigation area as examples to research and develop the topic concept, and in the support of a public welfare projects which named the key technology research of implement the severest water resources management policy by inland arid area which is approved by the Ministry of water resources of China.In the stage of theoretical research, based on the research direction and the research area, this paper illustrated that the most important supporting technology of the implementation of the most strict water resources management is GIS integrating a hydrological model, and studied four kinds of integration between hydrological model and GIS, and raised the specific way of various ways. Then, in the case of the mainstream models are not easy to achieve the integration, we according to the total amount of rainfall water balance principle is put forward in the irrigation area rainfall runoff computation scheme, and the scheme of the design of the I/O and the work flow design, making it can realize simple hydrological model for runoff forecasting, and finally the model code in the implementation of integrated information platform. In basic geographic information system function and prediction of hydrological model with based on the conditions for the realization of the proposed water resources allocation model based on the extreme drought, drought, usually, rich and extreme rich of five different scenarios and six different decision-making inclination and the scheme were I/O design and work flow design, and eventually the allocation model code implementation in integrated information platform.In the stage of practice, this paper made the user demand analysis, overall design, and the detail design of database, Raised the idea of the logic of the system can be divided into four levels, at the same time the function design of integrated information platform could be divided into the four modules. Then, we used the Microsoft Visual Studio 2010 and the SuperMap iObjects.NET 7C to design and develop a comprehensive information platform, and used the SuperMap iObjects database engine as data management interface, the C# as the programming language to coding, debugging and distributed deployment.In summary, this paper take the water resources allocation and management as the core and Hutubi irrigated area as the research area, researched and practiced the combination of GIS and hydrological model used in management of irrigation water resources, finally achieved the purpose and target of the integrated information platform which oriented the water resource allocation and management.
