REALTIME RAINFALL/WATER LEVEL/FLOODING OBSERVATION SYSTEM IN RADIO DEAD ZONE AND TRIAL IN THE HABIU RIVER BASIN

Abstract

 Small and medium-sized rivers, managed by local governments, have the problem that they do not have observation and real-time data transmission facilities. In this study, we discussed a system of observation facilities driven by a solar system and LPWA communication in radio dead zone and verified the feasibility and problems. In addition, by combining the observed water surface level with the results of flood analysis (conducted in advance), expecting to improve disaster prevention capabilities in radio dead zones.
