Abstract

Currently, the Ethiopian government has launched an extensive irrigation system in the country and is constructing various small earthen dams in each woreda. But there is a gap between the water potential that we have and the water needs for the command area that has not been adequately studied. To solve this problem, these researchers are trying to compare the potential of the existing dams and the water needs of the exiting command areas using a CROPWAT model. The main crops cultivated are tefe, wheat, corn, paper, cabbage, corn, etc. However, for this work, the researcher only admitted that the whole area was suitable for wheat because of suitability, need, ease of irrigation and agricultural practice as well of the dominant irrigation type of the community should be used. The gross area of the project area covers a total of 6,456 hectares. Of this, only 4,566 hectares of the command area has been used for agricultural purposes by the villagers of the study area, while 286 hectares of the command area is currently irrigated by Abrajit dams. From the CROPWAT software model analysis consequence we have agreed that the total artificial application of water request for the existing command area in the region at seventeen percent (70%) effectiveness is 179.5 millimeter and a net irrigation requirement of 123.1 millimeter of water. Currently, the irrigation system taking place in the study area is 77.4% of the dam's capacity. There is additional irrigation capacity in the study area that will allow 22.6% of the earth dams to be irrigated in the future without having to build an additional dam.
