THE CORRELATION BETWEEN DESERT PLUGGINGS & GROUND TREASURES IS ECONOMIC NECESSITY

Abstract

ABSTRACT In this study the specific data of twenty two desert plugging are gathered . some of the plugging were built , one of them is under construction , and the others are completely in design stage.The surface water area which is exposed to the air in each plugging calculated from the volume and dimension measurements . According to the atlas of Iraq climate, the average value of rainfall were calculated for the data of twenty years ago, the infiltration and evaporation loss value is of about 191575108.8 m3 / year. which equal to 75.89% of all plugging water. According to new irrigation system . using Surge irrigation , the value loss will sufficient for 278382.58 d . for Wheat crop and 589364.58 d. for Barley crop .in addition to human accumulation, This leads us to say ; that 14966 families can be worked in the suggested area , supposing each family works in 20 d for Wheat crop and also, 31686 families worked in Barley crop. In the trees field state, and according to (PRD)system the value of water loss sufficient for 40181518 Olive trees and 52247756 Grape trees .86411 and 112360 families can be worked in Olive and Grape field, respectively , when 500 trees were planted by each family. Any agricultural project may failure in two sequence water deficit periods, but in the periods of water surplus(wet store) the reserved water in ground treasurers can be used for irrigation along twenty aridity years in the following :19720.08 of wheat crop39073.83 of Barley crop2 846380 of Olive trees3 701129 of Grape trees To avoid the large loss caused by evaporation and infiltration mechanisms and to create work chances for people, this study which deals with water storage in ground treasurers.Water recommended to build agricultural villages for investment, finally study includes the consumption of water for human use at every years for every family .
