Abstract


In our country the freshwater resources for everybody is severe shortage.Recent years freshwater resources was polluted and pure freshwater resources was getting less. thus we should find an efficient way to manage and schedule water resources. Reservoir is an useful engineering facilities for water resources management. Reservoir capacity curve is an important basis for reservoir’s management and scheduling.and its accuracy has effect on flood control,irrigation and power generation.Because of the limited condition of surveying at that time and sedimentation for years, capacity curves of many reservoirs were not accurate. However, there were large quantities and restrictive conditions for topographic survey on the spot. To calculate capacity curves of all the reservoirs will cost many time and work. Recent years owing to the development of satellite that makes monitoring of small area waters come true. This paper takes Tongrenqiao reservoir for example, doing some research on satellite images determination method of reservoir capacity curve in order to find convenient, operational and reliable way on the spor.In this peper many satellite images of Tongrenqiao reservoir were taked and dealt with.The water area at different water level was obtained according to the satellite image data, and the function relationship between the water level and area was built. Then the Reservoir capacity curve was derivate by calculus. Compare with the water balance method, the result was within the bounds of allowable deviation. It was demonstrated that the accuracy of satellite images determination method meets the actual operation and management demand. Satellite images determination method can provide reliable basis data for reservoir management and water resources schedule, and it will have good application prospects.
