Outline of Final Research Achievements

A monitoring system was developed for a river mouth where environmental degradation is crucial. The system was composed of quick aerial photography and a X-band radar system. The use of UAV, Unmanned Radio-controlled Helicopter, was introduced to replace the originally planned kite aerial photography technique. The smart photography technique by UAV was combined with a continuously operated X-band radar system to develop a unique and adaptive monitoring system of environmental change due to sudden events around a river mouth.
