Water Balance Calculation Based on Hydrodynamics in Reservoir Operation

Reservoir operation plays an important role in reservoir management. In operation, water balance calculation is a very step. At present, one of the main challenges that inflow cannot be calculated accurately due to jacking reservoir, which produced by downstream after original course river has changed. Another reason capacity influence dynamic storage capacity. order overcome these problems, this report shows land zone front dam can used calculate capacity, since it serve as boundary for hydrodynamic model, then improve accuracy. The Three Gorges Dam was selected case study. results show compared with measured data, RMSE (root mean square error) proposed model 8.5%, whereas traditional 25.9%. contributions and novelty paper are: (a) combines make more accurate; (b) (c) method provides new way balance, short-term operation. application indicate study provide technical support fine reservoirs.
