Potential Rainwater Harvesting Improvement Using Advanced Remote Sensing Applications

Abstract EN

The amount of water on earth is the same and only the distribution and the reallocation of water forms are altered in both time and space.

To improve the rainwater harvesting a better understanding of the hydrological cycle is mandatory.

Clouds are major component of the hydrological cycle; therefore, clouds distribution is the keystone of better rainwater harvesting.

Remote sensing technology has shown robust capabilities in resolving challenges of water resource management in arid environments.

Soil moisture content and cloud average distribution are essential remote sensing applications in extracting information of geophysical, geomorphological, and meteorological interest from satellite images.

Current research study aimed to map the soil moisture content using recent Landsat 8 images and to map cloud average distribution of the corresponding area using 59 MERIS satellite imageries collected from January 2006 to October 2011.

Cloud average distribution map shows specific location in the study area where it is always cloudy all the year and the site corresponding soil moisture content map came in agreement with cloud distribution.

The overlay of the two previously mentioned maps over the geological map of the study area shows potential locations for better rainwater harvesting.
