Diversion construction (DC) technology is one the structural solutions using stones with slope and tan 30 to slow the water flow and to deposits the carried materials with water to allow water to pass throw the inlet (gate) to the fields that need to be irrigated without damaged mainly vines and qat crops. The site of DC must be built in direction of water flow to direct it to pass to the fields need to be irrigated to get a benefit from this water harvested the height of the DC should be equalled to the height of the cultivated land which ranges between 2-4 meter and the width is 1.5 meter and the length is ranged between 40-60 meter based on the width of wadi bed. The DC should not built totally in one time but should be gradually and by the time as a result of deposit be come at the same level of fields need to irrigated. Finally when the height of DC become equally to level of the field need to irrigated the gate should be determined according to water requirement of cultivated crops. After that distribution channels should built at 1-2 wide, 0.5- 0.8 height and 10-100 length. Such as this type of technology is considered a long term process in the past due to lack of equipments and implements. However now it can be done in short time if all requirement provided especially funds and equipments.
