Characterizing Seasonal Residential Water Use In The Khan Younis Governorate Using Landsat 8 - Derived Land Surface Temperature

Urbanization increases land surface temperature (LST) due to urban surfaces radiating heat, which is influenced by variations in building materials, heights and spacing, and street geometry amongst other natural and manmade factors [1]. LST increases water consumption especially in summer, due to human behavior such as increased showering, drinking, entertainment and cooling. This research aims to use thermal remote sensing data and GIS tools to quantify the impact of LST on water consumption (WC) for the different seasons in Khan Younis Governorate, Palestine. Correlation was studied between water meter data for 2017 (28,000 houses) and the corresponding LST data of Landsat 8 at 100 m resolution. This study shows the potential of remotely sensed LST datasets for estimating WC under various seasonal climatic conditions, which has the potential to be a valuable tool for the management of water resources in urban areas.
