Application of remote sensing techniques for designing small reservoirs in Duhok governorate

Abstract EN

The reservoirs and ponds are repositories to store flood water from the rain use for a variety of purposes, including to control the flood waters and to minimize its negative effects on soil erosion and degradation , as well as taken advantage of stored water to irrigate crops and watering animals and other activities to ensure the sustenance farmer, particularly in the period of the decline of the rain and the lack of water sources, that the use of Technology remote Sensing supported by maps of geographic information systems and digital elevation model (DEM) in the design of water tanks facilitates the process of saving money, effort and provides surveys are costly and cumbersome on the ground, in addition to providing a lot of information pertaining to river basins and water parks (watershed).

Including elevations and the length of inclination (x) and inclination angle (s), the results of a survey of reservoirs under study showed, both field and subsidies modern technology that there are obvious errors in the designs of those watershed particular with regard to the size or capacity of the reservoir and the choice of location and extent of benefit from its construction as well as measuring the extensions catchment as a body obstructive or through spills and freeboard where we found that the basin Galbook (1) has half the possibility of storage runoff and the rest is wasted without interest, there is no objectives clear from the establishment of some reservoirs , such as Barebohar and Bablo where the latter close very public highway and road to Duhok – Amedia; spillway for the Barebohar is small and not enough to discharge the excess a forth of water in maximum peak runoff.

All measures for safety freeboard except for Bablo are less than the standard measurements.
