Abstract
Currently, more and more arid and semi-arid areas in Northwestern China are facing with severe water problems. The Shiyanghe River basin is in the east of Hexi Corridor in Gansu Province with little rainfall and fragile ecological environment. As water pollution and water waste exist with water shortage, a serious conflict of water supply and demand is arising, accompanied with a series of water ecological problem. Thus, we must take measures to ensure the water resources to be used properly for long-term sustainable development. Water resources operation is taken reasonably which can achieve the overall regulation of basin water resources and which is an important method to achieve sustainable development. Taking the Shiyanghe River Basin as the research object, based on the basin data, this paper built the runoff forecasting model, water demand prediction model, water resources operation model and groundwater simulation model. Therefore, an information system platform for water resources operation in Shiyanghe River Basin is built based on GIS with an integrated data and computational models.
Highlights
With the rapid development of global economy and population, water usage is increasing continuously, and water shortage has become the primary contradiction of water resources
The information system platform for water resources operation in Shiyanghe River Basin is a GIS-based water resources management decision support system developed with C# language, MSF and GAMS modeling tools based on model base and database
The following pictures show some functional interferes of the information system platform for water resources operation in Shiyanghe River Basin
Summary
With the rapid development of global economy and population, water usage is increasing continuously, and water shortage has become the primary contradiction of water resources. The current development and utilization of water resources is increasingly affected by human activities, so a lot of conflicts have occurred in the time-spatial distribution of water resources and the demand for industrial and ecological water. All of these have greatly constrained the sustainable development of economy, society and ecological environment [1]. Through the combination of runoff forecasting and demand prediction, regulating water in the area of a basin, can make the maximum usage of existing water resources and solve the contradiction between uneven distribution and huge demand of water resources.
