Officially launched in 2015 by the National Aeronautics and Space Administration (NASA), the SMAP mission is an orbiting satellite that measures the amount of wetness in the top layer of soil incrementally every 2-3 days. These Soil Moisture Active Passive (SMAP) measurements rely on radiation frequencies that point to different levels of moisture on the surface of  earth’s soil and are useful for scientists because it allows them to construct maps indicating the level of soil moisture globally.

Flood hazard assessments are essential to design land-use ordinances or norms that minimize the exposure of future critical infrastructure and potential new settlements to such floods. Flood hazard assessments rely on flood modelling, which can be conducted using flood modelling software.

Flood modelling in Guatemala using different digital elevation models

The Coyolate river is one of several rivers that originates in the highlands of Guatemala and in the foothills of the Fuego and Acatenango volcanoes. Its lower basin, in the Pacific coastal plains, experiences floods triggered by intense precipitation and is affected by massive sedimentation as a result of the transport of volcanic material from the cone of the active Fuego volcano during the rainy season.
