EVALUATION FOR THE TRANSPORT OF CORBICULA JAPONICA AFTER THEIR SETTLEMENT IN LAKE SHINJI

Abstract

 In order to know the transport process of Corbicula japonica in Lake Shinji, we conducted wave flume tests and field survey around the shore. The laboratory tests reavealed that we could apply sediment transport theory to the transport of Corbicula japonica with some adjustment depending on their sizes. Field data showed that their transport was mainly driven by wave actions in the manner of not suspended load but bed load transport. Moreover, a wave model of SWAN could evaluate the possible their transport area and revealed that more than 10 mm size could hardly be transported.
