The geographical context of the research is the Fitamaria, Fisakana and Sahanamby sub-watersheds, in the Fandriana district, Amoron'i Mania Region, Madagascar. Each sub-catchment has these physical and morphometric characteristics: surface area A, compactness index and slope index. A secondary character, such as the overall slope index, and intermediate calculation characters: perimeter P, total vertical drop D, length of equivalent rectangle L, confluence ratio, length ratio and drainage density. At present, GIS can automatically calculate all the morphometric parameters of a sub-catchment, as well as topography and elevation. According to the analysis of various researchers, soils are grouped into different well-defined classes, with solid constituents comprising mineral and organic constituents, and liquid and gaseous constituents.","brand":"Our Knowledge Publishing","offers":[{"title":"Default Title","offer_id":53703755694422,"sku":null,"price":0.0,"currency_code":"EUR","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0925\/5829\/5382\/files\/product_image_9786208922399_1.jpg?v=1778867498","url":"https:\/\/www.momoxbooks.com\/products\/archid-razafimahefa-volasoa-general-framework-for-soil-and-water-resource-management-9786208922399","provider":"momoxbooks","version":"1.0","type":"link"}
