Thermal pollution of the waters of Mosul and Haditha dams and its environmental effects(comparative study)

Abstract

Temperatures plays especially the daily and seasonal ones, play an important role in changing the spatial pattern of the aquatic ecosystems of dams, and large dams contribute to changing their water temperatures by releasing cold or warm non-seasonal water, which leads to reducing the daily fluctuations of temperatures, and it is known The scales that can measure water temperatures are few and rare, and remote sensing data has provided a new approach to monitoring thermal pollution downstream of rivers or dams.

This study used a modern geographic information system program (Arc GIS.v.10.8) based on Landsat satellite visual data (Land Sat.8.ETM+) and for several observations, where the thermal pollution caused by the Mosul and Haditha dams and its environmental effects was monitored and evaluated. On water, biological diversity and plant life, reducing the dissolved oxygen content in water and conducting chemical reactions, after these pollutants were detected in converting the digital values ​​of satellite images into spectral radioactive values ​​by the thermal sensors within the thermal range (11) of the moon Industrial Landsat (8).
