The computation approach for water environmental capacity in tidal river network *

Considering that the conventional systematical optimized method and the trail-and-error method are not efficient in computing water environment capacity of tidal river network, a new analytical computation approach to water environment capacity of tidal river network was presented. Furthermore, this new method was applied to estimate the water environment capacity of river network in Chongming Island after establishing hydrodynamic and water quality model, which shows the newly developed analytical computation approach efficient and reliable both in theory and in practice.
