Prediction of flood risk

Posted on Dr. Sat Kumar TomerPosted in agri, disaster, env, gis, math, satellite, urban, water

The flood depends upon the intensity of rainfall and the infiltration (absorption) capacity of soil which is related to soil moisture. The satellite soil moisture provides information on the soil infiltration capacity. A combination of real-time precipitation availability and satellite soil moisture can predict the floods. Based on precipitation forecast and soil moisture data, the […]

Monitor agricultural drought using satellite data in near real time

Posted on Dr. Sat Kumar TomerPosted in agri, disaster, env, geo, gis, math, satellite, water

A deficit in the available soil moisture for agriculture is termed as drought which results in the lack of crop growth and production. Microwave satellite provides information about the available soil moisture in near real time which is useful for drought early warning. The conventional method of monitoring drought based on crop variables e.g. NDVI […]
