Abstract
There are complicated phenomena such as a red tide and a blue tide that cause serious problems and food chain at a coastal zone. It is extremely difficult to clarify interaction processes among those phenomena only by using experimental approaches. We focus on a flow in a shallow water area and we develop a finite element analysis code with a shallow water long wave equation for solving the problem. In this research, we especially implement a function of considering monitored wind flow precisely in the simulation. To validate fundamental reliability of the simulation, it is applied to sea water flow in Tokyo bay.
