A study of the climate change impacts on Al Shuwaija Marsh - Wasit province using satellite remote sensing

Abstract

A study was described and analyzed using the Landsat series of images to detect flood waters in Al shuwayja marsh for the period 1972 to 2019, monitor the spatial scale and spread of flooding. The images were first classified in two ways unsupervised and supervised. Subsequently, QGIS was applied to extract the area of submerged areas from the Landsat images. These spaces were analyzed to determine the nature of the spatial scale and duration of the flood and to show how the flood spread over time. This study demonstrates that it can use satellite images with geographic information systems to effectively monitor and analyze the spread of flood waters in an area prone to flooding. Therefore, the results of this study will help to take an initiative to reduce the impact of flood risks and increase flexibility in flood management.
