Abstract:As for the local sour-and-fill problem around pier-type water intakes in the water supply and
drainage project of large-scale coastal power plant, the theoretical formula of sour-and-fill intensity is gained for a
single water intake, according to the potential theory and seabed change formula under cylindrical coordinate
system. In addition, finite difference method is used to disperse seabed change formula under Cartesian coordinate
system. The convenient sour-and-fill numerical simulation method is put forward too. The wa
