Monitoring of Water Surface Change of Haditha Dam’s Lake Using Satellite Data Technique

Abstract

Water bodies in Iraq and other countries are considered the essential key for human life as they play a large and influential role in the country’s economy. Thus, the strategic plans of water management must be developed according to the need for future requirements. The current study aims to monitor the change in the water surface area of Haditha Dam Lake by calculating the surface area of the lake over a sequential time (1985-2019). GIS and Satellite imagery techniques were used to achieve the goal of the study. Landsat Space Archive was used with its fifth, seventh and eighth categories according to Path 170 / Row 36. The results showed that the lake generated from the dam was tested by three main stages. The first stage (1985-1988), the second stage (1988-2000) and third stage (2000-2019). The study presented that the average area of the Haditha dam Lak for the period 2001-2016 was 313 km2, compared to the average area of 418 km2 for the period 1988-2000, which means that the difference in the average surface area decreased by 25%. The Maximum and minimum water surface areas were about 427 km2 and 148 km2 for 2014 and 2015 respectively throughout the period time of 1988 to 2019. The declination behaviour of the surface area was observed from 1988 t0 2019 for the general trend line with a slope of 11.8.

Karstification Problems in the Haditha Dam, West Iraq

“…They concluded that understanding the effects of running hydropower plant turbines on the dam body is one of the major safety concerns for the earthfill dam, besides other safety concerns such as karstification. Sissakian et al (2018) described the general geology of Haditha Dam, and Hason et al (2020) conducted change detections study over the impounded area of Haditha Dam reservoir for many years, see Figure 1. The main aim of the current study is to elucidate and discuss the influence of the karstified rocks at the dam site and reservoir on the design and especially the length of the dam and the need for side extensions.…”

Using GPS and Run-Off Rates Data to Study the Close Monitoring Networks for Dams – Al-Kut Barrages as a Case Study

“…Therefore, deformation measurements and analysis require high-precision surveying equipment and analysis of the data to identify and avoid hazards. In addition to studying, the sediments collected at upstream of the barrage over time and understanding the eff ect of sediments on the effi ciency of the barrage gates [Abedalrahman and Mnaty, 2021;Hason et al, 2020].…”
