3D Temperature Simulation by IMJA-3D
• Projecting annual temperature distribution in the region
• The use of ALOS Image from JAXA for preparing boundary conditions
• Early warning of Melting of ICE.
Technologies for GLOF
• Early Warning System using JAXA Image, Local Monitoring and Modeling
• Technique to Reduce the Amount of Volume of Water through engineering solution by– Bypass water channel– Protecting unstable moraine wall
• Sediment Control– Protect against Debris Flow
