Reconstruction of Long-Series Runoff Data Based on Hydrological Simulation and Quantile Mapping

A long series of runoff data is the basis for water conservancy project planning, resource management, and so on. When in short supply, it needs to be extended reconstructed. Taking Zhiyan Reservoir Qiantanglong Lanxi City as research objects, based on Water balance model with double parameters (WBM-DP) Quantile Mapping (QM) methods, monthly income two reservoirs 59 years from 1960 2018 was analyzed. The library sequence refactored. constructed WBM-DP has good calibration results, extending inflow Reservoir. After QM method used correct deviation, error between simulated measured value significantly reduced. this paper can provide reference reconstruction data.
