| source_abstract | The watershed contains forty-one watersheds delineated within five river basins in Afghanistan, five of them are non-drainage areas. The size of the watersheds was limited in order to retain meso-units suitable for hydrological and agricultural/agro-meteorological monitoring and analysis and watershed management activities. Upper Hilmand is the largest watershed in Afghanistan, covering 46,882 sq. km, while the smallest watershed is Dasht-i Nawur, which covers 1,618 sq. km. With the water catchments classification for Afghanistan prepared by FAO, GIS desk work was conducted at AIMS office in Kabul and Mazar-i Sharif to delineate the actual boundaries of the defined watershed and river basins. An initial water catchment maps (river basins and watershed) was produced in early 2003. The boundaries were drawn manually on computer screen using as screen background a DTED elevation model at 500 meters elevation. The work was operated on Arc-View 3.2 software. These initial coarse maps were taken in the field for field verification during extensive agriculture field surveys organized by FAO in 2003. Revisions and fine-tuning of the maps were made based on field observations and with the availability in late 2003 of a DTED elevation model at 3 arc degree intervals (100 meters elevation). Also, a number of other available digitized maps and satellite images of Afghanistan were used to fine tune the boundaries. Similar method of delineating boundaries was retained. Purpose: Afghanistan is mostly a agrarian country with a huge scarcity of fresh water during the summer. Agricultural development is one of the key priority of the Afghan government. Presently very little information available for a comprehensive agriculture planning. Watershed classification and mapping was done to provide a framework for planning. Information was for each watershed, so better planning can be done. Designations and boundaries: The designations employed and the presentation of material in this electronic product do not imply the expression of any opinion whatsoever on the part of the United Nations Development Programme (UNDP) concerning the legal status of any country, territory, city or area or of its authorities or concerning the delimitation of its frontiers or boundaries. |
