A PhD thesis at the College of Engineering at the University of Basrah discussing (Modeling sediment transport at the back of the Al-Amarah Dam in southern Iraq)

The thesis presented by the student Abbas Jabbar Ismail dealt with four parts: The first part deals with the field and laboratory aspect, where

The field side included the distribution of 20 cross-sections along the study area of ​​about 5 km, to obtain

On the field data represented by readings of flow velocities and sediment samples at the specified points and depths

As for the laboratory aspect, it included obtaining both the grain gradient curve, and the weight values qualitative river bed samples 

The second part is the theoretical part, using two numerical models, one of which is a three-dimensional model

It's called SSIIM and the other two-dimensional one is called Mike 21 Flow Model FM.

The third part included the development of a new mathematical formula for calculating suspended sediment load based on

The principle of dimensional analysis and multiple linear regression techniques implemented by the statistical software

The fourth part involved the creation of sediment classification curves. The results of these curves gave several relationships

The thesis aims to analyze and simulate both the movement of sediments and the flow of water to the selected study area, which is located at the back of the embankment of architecture.

The thesis concluded that a graphical representation of each of the flow velocities and concentrations was obtained

Suspended sediments in three dimensions

And satisfactory results were obtained through comparison with field data

Depending on the coefficients of selection

The results of this formula also gave good agreement through comparison with the observed data based on the coefficient of determination

And also based on the values ​​of the statistical coefficients that were also used to evaluate the accuracy of the results of the new formula

A good agreement was also obtained in comparison with the observed values ​​based on the determination coefficients
