Water Purification System using Artificial Lagoon

Abstract

The water quality in an inner part of a gulf encircled big cities is chronically bad, because the pollution load is very high. It is known that the so-called UTSURO, an artifitial lagoon using rubble-mounted breakwater, has water purification functions for such an enclosed sea area. In this research, the mathematical model is constructed using ecosystem models. The result of numerical simulation shows good agreement with measured values, and also shows the system is effective for purification of water quality.
