Mosul Dam is one of the important dams
in Iraq, it suffers like other dams from the problem of sediment accumulation
in the lake. The daily surface runoff was estimated from seven main valleys in
the left bank of the lake during the period (1/1/1988-31/8/2016) by applying SWAT
model. The model performance was assessed using the statistical criteria R2,
IOA, NSE and T-Test, the results were good. The averages annual surface runoff from
the main valleys to the lake ranged between 3.3*106 m3 to
42.1*106 m3. The daily sediment load was estimated by
four methods, Bagnold method was used in SWAT sediments transport simulation,
while Yang, Toffaletti methods and Excess Shear Theory were programed by
MATLAB, The performance of sediments transport simulation using Bagnlod, Yang
and Excess Shear Theory methods was
assessed using the same four statistical criteria and the results were good, The averages annual sediment load from the
main valleys to the lake were (5.78*103 - 68.62*103),
(1.49*104 - 42.13*104), (8.46*103 - 160.77*103)
and (4.26*104 - 78.6*104) tons for Bagnold, Yang, Excess
Shear Theory and Toffaletti methods, respectively. The valley Jardiam is the
main supplier of sediments to the left side of the dam lake with 56%.
