Study on Water Level Prediction in the Ganjiang Valley

摘要

This paper was based on the Ganjiang Valley's 50a rainfall data (1959～2010) and the WRF numerical weather prediction model rainfall to establish a new mathematical model for water level prediction in the valley through the excellent performance technique - Muskingum model parameters optimal estimation, which realized the quantification of water level forecast. In the last of this paper the rainfall data in April 2012 of this valley was used to test the new model and the experimental results show the error between the model and the observed data is varied in -15 cm to 15 cm, it is very small.
