Reducing Water Level (-5m)

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
