Suitability for Water Harvesting : Micro - Catchment system Contour ridges, field crops

The systems evaluated include 13 micro-catchment systems, based on combinations of 6 techniques and 3 crop groups, and one generalized macro-catchment system. The environmental criteria for suitability were based on expert guidelines for selecting water-harvesting techniques in the drier environments. They included precipitation, slope, soil depth, texture, and salinity, as well as land use/land cover and geological substratum. The dataset included interpolated surfaces of mean annual precipitation, a high-resolution digital elevation model, a soil map of Syria, a land use/land cover map of Syria, and a geological map of Syria. Contour ridges are bunds or ridge...

Description

The systems evaluated include 13 micro-catchment systems, based on combinations of 6 techniques and 3 crop groups, and one generalized macro-catchment system. The environmental criteria for suitability were based on expert guidelines for selecting water-harvesting techniques in the drier environments. They included precipitation, slope, soil depth, texture, and salinity, as well as land use/land cover and geological substratum. The dataset included interpolated surfaces of mean annual precipitation, a high-resolution digital elevation model, a soil map of Syria, a land use/land cover map of Syria, and a geological map of Syria. Contour ridges are bunds or ridges constructed along the contour lines, usually spaced between 5 and 20 m apart. The first 1-2 m upstream of the ridge is used for cultivation, whereas the rest is used as a catchment. The height of each ridge varies according to the slope's gradient and the expected depth of the runoff water retained behind it. Bunds may be reinforced by stones if necessary. Contour ridges are one of the most important techniques for supporting the regeneration and new plantations of forages, grasses and hardy trees on gentle to steep slopes in the steppe. In the semi-arid tropics, they are used for arable crops such as sorghum, millet, cowpeas and beans.
