Fig. 6.13 Map of study area in K ā r ū n River

This graph shows inequality between the inlet and output TDS. The inlet TDS is
usually more than the outlet TDS (Badrghasemi 2002 ).
This study indicates that a TDS buildup is to be expected in the Kharkheh
reservoir in the coming years and that this will limit the use of the water for
irrigation purposes. Thus, we concluded that the implementation of TDS accu-
mulation prevention strategies is necessary to ensure long-term usage of the
reservoir.

6.4.2 Second Case Study

The K in River is the most important river in the south of Iran. However, it

receives various wastewaters from a wide range of sources, including domestic,
agricultural and industrial. Thus, analyzing the effects of pollutants on the water
quality of the K

ā r ū

ā ū

in River is inevitable. Studies have been conducted in other parts
of this river, or similar rivers in Iran but a lack of analysis on this lake persists.
The study area is the region upstream of the Gotvand Dam on the K

r

n River
which is 32,425 km 2 to well beyond Gotvand Dam and two main cities following it.
The Gotvand Dam is located in the south west part of Iran in the Khuzestan
province between 48

In this case study the QUAL2K was applied, a numerical hydrodynamic and
water quality model provided by the U.S. EPA, to analyze the effects of pollutants on
the water quality of the K

River is located in South West of Iran and many dams are constructed and are being
constructed on this river for the generation of electricity and water consumption. At
