Anti-Scour Measures for Nakagawa River
River / Dams / Coast and Oceans / Water Management
Tokushima Pref. Japan 2004-2007
Located in Tokushima Prefecture, the 125 kilometer-long Nakagawa River naturally changes course drastically from one side to the other, and the location and shape of its banks changes every time the river overflows or a flood occurs. This constant change in the sand banks has made implementation of effective anti-flood measures for the river difficult.
When designing river channeling projects or anti-scouring projects for a river it is necessary to predict how the river course and bank are going to change. CTI has developed a two-dimensional river course prediction model that enables projection of how the sand banks are going to change. Combined with live information this data, provides a clear image of where to implement necessary measures and locates the emergent areas that need attention.
