English Abstract

The present thesis takes advantage of the possibilities of GIS and remote sensing systems in the analysis of satellite images to derive the storage capacity of the Hamren Dam.

located in Diyala province in Iraq.

The reservoir has an area of 340 km2 when operating at 104 m and with a storage capacity of 2.60 billion m3.

Area – volume of the dam was derived using a digital elevation model DEM based on data from 37 satellite images of the Landsat satellites group during the period 2008 through 2016.

In this study a new method is developed to extract the water body of the dam.

using the Normalized Difference Water Index (NDWI) to establish the surface area and the exterior boundary of the lake.

The images were used to obtain a three- dimensional terrain model of the bottom of the lake.

These 3D results were used to calculate the surface area and storage of the lake at every level.

Relationships were established between: 1- elevation and storage capacity; 2- elevation and surface area.

and 3- the surface area and storage capacity.

These relations were represented graphically and were compared with those of actual design figures.

which were prepared at the designing stage of the dam.

The 3D terrain models obtained from the 37 images were used to derive the volume of sediments accumulated behind the dam during the period 1981 through 2008 when the lake almost dried out completely in 2008 Results show that the average volume of sediments reaching the lake was around 9 million m3 annually.

Thus.

the lake volume decreased by 243 million m3 during the operation period 1981 through 2008.
