| description | Water cool Islands (WCIs) are a key strategy for mitigating Surface Urban
Heat Islands (SUHIs) despite the characteristic limitations of water bodies.
This paper reports an analysis of the spatial and temporal variation in
Surface Urban Heat Island (SUHI) intensity in the Mila region of Algeria,
with a focus on evaluating Water Cool Island's (WCI) effectiveness of the
country's largest and most substantial hydraulic infrastructure, the
Beni-Haroun Dam. Landsat 5TM and Landsat 8 OLI/TIR imagery from 1991 to
2022 were required and analyzed during the hottest and driest periods.
Additionally, a comprehensive assessment of the Weighted Normalized
Difference Water Index (WNDWI) was conducted, followed by classification and
mapping using ArcGIS 10.8. The findings demonstrate a significant
correlation between the water index and SUHI, with the WNDWI showing the
lowest surface temperature values. This resulted a global cooling intensity
(WCI= −1.39°C), translating to a temperature reduction of 1.39°C across
study area, with a notable substantial cooling effect observed in the urban
areas surrounding the dam. This study underscores the crucial role of water
surfaces in mitigating heat islands, offering valuable in-sights for urban
planners seeking to enhance urban climates by modifying existing water
surfaces or designing new ones. |
