ONCOMELANIA'S TRANSPORT IN RIVER AND ITS CONTROL

摘要

Schistosomiasis is a parasitic disease mostly found in areas along the ChangJiang River of China, The disease spreads solely through an intermediary named oncomelania, so the spread of schistosomiasis can be controlled by properly design water intakes that prevent oncomelania from entering farming land or residential areas. This paper reports a successful design process and a new oncomelania-free intake device. The design of the new intake is based on a sound research program in which extensive experimental studies were carried out to gain knowledge of oncomelania eco-hydraulic behavior and detailed flow field information through CFD simulation.
