Intergrated system for daily streamflow prediction and management method using the same

摘要

The present invention relates to an integrated system for predicting a watershed daily outflow amount and a management method thereof and, more specifically, to a system which predicts an outflow amount generated in a watershed in a daily unit by precipitation (rain and snow) for the water management of a river watershed. The integrated system includes: a storage means which includes data about watershed information, precipitation, and weather; a watershed daily outflow amount calculation processing means which selects at least one of a plurality of daily outflow prediction algorithms which is a conceptual hydrological model by using watershed information, precipitation, and weather data, and calculates a watershed daily outflow amount of each watershed; an input means which is to input information stored in the storage means; an output means which displays content inputted by the input means and a result calculated by the watershed daily outflow amount calculation processing means; and a parameter correction processing means which corrects at least any one of parameters of each daily outflow amount prediction algorithm included in the watershed daily outflow amount calculation processing means based on measured river outflow amount data. An integrated information processing system having control and management functions is proposed inside and outside a country to build a daily outflow amount prediction algorithm, which is being utilized independently, as an integrated system, controls and manages parameters and increases user convenience by manually and automatically correcting parameters of each outflow prediction method when a measured outflow amount exists.
