Abstract

        The study of lakes and how they are represented spatially is important and has a key role in the construction and development of any country and this depends on the main location of the lake and the possibility of investing its water in agriculture, tourism, electricity generation and others after water scarcity and low level of placements, which led us to study Lake Talker through the use of the model of digital height and topographic maps to reach the possibility of improving this model to reach an academic study that can be used in other scientific fields Lake Al-Tharthar is located 120 km northwest of Baghdad between the Tigris and Euphrates rivers, with an area of 2,710 km2.
 
The highest storage level is 65 meters above sea level and the volume of water storage at this level is 85.89 billion m3. The lake is one of the largest natural depressions in Iraq, where it was established in 1956 to store excess water from the Tigris River, so that adequate amounts of irrigation water can be returned to the two rivers whenever needed.1 Lakes and dams have been established and developed mainly to avoid floods that feed Iraq's rivers from time to time.
Two methods of completion were thus used: the Radail Basin Function method and the
Empirical Bayesian Kriging and we were able to note that the Payson Road is the best in spatial fulfilment to reach the representation of the 3D shape of the lake.
Based on the above, the research has reached a number of results, namely, the possibility of developing improved digital altitude models for different regions of Iraq with local specifications that form the basis of similar studies and research.
