Shewah Soor Earth Dam

Client: General Directorate for Dams and Water Reservoirs -Erbil
Project Description:
The proposed earth dam is to be located in the Shewasoor Valley, in the Kurdistan Region of Iraq. The dam receives rainfall from a catchment area of approximately 104 km2 with total live capacity equals to 6.7 million m3 (MCM) and dead capacity of 0.75 MCM over a useful life of 390 years.
he maximum spillway discharge for this proposed dam is 157.5m3/s. The total height of the dam is 34 m at its highest level and 10 m width for the crest. The down- stream side is of slope 1: 2.75, while the up-stream side of dam is of slope 1: 3.0 protected with concrete blocks.
The core is extended to rock layer as a cutoff, while 1.5m thick blanket of same core materials is placed at upstream side of the dam to length of about 250m into reservoir.
