In order to prove the feasibility of the separation of flood and tidal waves,three tests are conducted by using the approaches of the ideal models to analyze the assumption,stability,rationality and validity of the BSM.

Hydrodynamic model for flood routing in a floodplain river;

Radial basis function-neural network model for channel flood routing;

Consideration of weir control in flood routing;

This paper summarizes the current status and development of the method for flood regulating calculation of reservoir,reviews some current typical methods and takes case study as example based on computational efficiency.

Improvement of Muskingum flood calculation model and it s parameter estimation using ant colony algorithm;

Based on river flood calculations principle,the mathematical calculations model was established for conforming river hydraulic characteristic and its law of change.

For the parameter estimation problem of flood calculation of Muskingum model,first,it is summed up as a non-linear parameter optimization problem,and then solved by adaptive accelerating differential evolution(AADE).
