Flood Forecasting And Reguration Research Of HuangLongTan Reservoir

Flood forecasting model is the technology which occures with the application and development of computer technology, simulates the hydrological process which happened in the watershed., and simulate the natural hydrologic processes through a series of mathmatical equations. According to the priority of hydraulic tasks and application rules of regulations, resorting the storage capacity of reservoir, and on the condition of guranteeing the dam safety, the reservoir regulation is a kind of controlled reservoir application technique regulating the inlet process entering reservoir, insuring flood safety downstream of the dam, generating more electricity, and improving the integral utilization efficiency.Anti-flood forecasting regulation is according to some degree of precision and predicting period of flood forecasting of reservoir, before the coming of flood to make room for the coming flood, to have the function to improve the anti-flood capacity. In order to study the regulation of forecasting and flood discharge capacity, one should make careful research and assessment of precision, predicting period, current regulation pattern of flood forecasting of reservoir, throught integrated analysis, to obtain the methodology of the forecasting and flood discharge capacity.The primary study of this paper is through the combined study of both watershed hydrological characters of HuangLongTan Reservoir and structural characters, in combination of the current meteorological and hydrological forecasting techniques, to develop hydrological forecasting model which fits the reservoir, to establish the scenarios of flood forecasting of the reservoir, to improve the precision of flood forecasting and predicting period of the reservoir, to provide reliable safeguard to anti-flood and electricity generation. To study the flood forecasting under extreme storm, and the different flood generation under different storm levels. Study the flood regulation under current conditions of HuangLongTan reservoir, explore under the condition of insuring reservoir construction safety, if the HuangLongTan Reservoir can adopt effective safe forecasting and flood fore-discharge regulation in theory. And how to make use of the flood forecasting of the reservoir to make effective and safe forecasting and flood fore-discharge regulation, and to establish different flood fore-discharge regulation scenarios. To solve the conflict between anti-flood of the reservoir and anti-flood task of downstream, and the conflict between reservoir anti-flood and beneficial use.
