In present study, the remote sensing ( techniques and geographic information system ( were used to develop the topographic map for calculation the volumes of earth work depending on Shuttle Radar Topographic Mission ( which data cover aboutabout80 of the earth The above data was used to develop the topographic data for Al Gaara dam in the Iraqi western desert, and the compression between the earth work volumes that calculated by this method with which was calculated by surveying Also, the hydrologic properties of the catchment area area, length of main stream, slope etc) were determined to calculate the storage volume and maximum flow according to unit hydrograph theory The results of present study, refer to a good accuracy to calculate the earth work volumes, as well as, the RS and GIS save time and moneymoney.
