Geomorphometric analysis of Alfdhay Valley basin using geomatics techniques and the possibility of investing it for water harvesting

Abstract

The study aims to analyze the morphometric characteristics of the Alfdhay Valley basin in northern Iraq, as it is one of the important and promising mountain basins for investment in water harvesting projects through the use of geomatical techniques and their use in morphometric analysis. The deep structure constitutes 48.08% of the total area of the area, and geological formations predominate, most of which go back to the third and fourth times. The morphometric ratio was (0.6) elongation and roundness reached (0.4), while the gradient ratio was (9.8). All morphometric coefficients indicate the basin’s youth, the regularity of its water drainage, and the lack of its sedimentary output
