Abstract: For river-lake system, the riverbed topography and flow
boundary are very complex. And it must meet small-scale and high-precision
research requirement of navigable conditions. A plane 2D flow mathematical
model is established for small-scale and large-range river-lake waterway
system based on Mike21 software. It is validated by measured hydrological
data. Then it is used to study the influence of the lake-control project on
navigation conditions of the Dongting Lake. The results provide a scientific
reference for the analysis of navigation benefits of the lake-control
project.
