Urbanization strongly correlates with land use cover (LULC) dynamics, which further links to changes in surface temperature (LST) & urban heat island (UHI) intensity. Each LULC type influences UHI differently changing climate, therefore knowing this impact connection is critical. To understand such relations, long temporal studies using remote sensing data play promising role by analysing the trend continuity over vast area. Therefore, study aimed at machine learning centred spatio-temporal analysis of LST and indices identify their intra-urban interaction during 1991-2021 (summer) Imola city (specifically representing small environment) Landsat-5/8 imageries. It was found that 2021 increased 38.36% from 1991, whereas average Normalised Difference Built-up Index (NDBI) 43.75%, associating thermal stress area evaluated ecological evaluation index. Major transformations included green into agricultural arable-land built-up. Finally, modelled output shows built-up vegetation index have impacted LST. This study, help relative land-use dynamics on level specifically respect settings. Further assisting designing regenerating contexts stable configuration, considering sustainability liveable for benefit health public fragile population particular.

Global Digital Elevation Models (GDEMs) have been increasingly used to assess the risk of flooding worldwide. However, their effectiveness and performance flood models in areas with complex terrain, such as Jeddah, Saudi Arabia, not comprehensively studied. This study aims compare five distinct − 30-m SRTM, ASTER, 90-m MERIT, 10 m Sentinel-1 DEM, 12.5 ALOSPALSAR - estimating inundation extent depth Jeddah watershed, including three dams. Both hydrological hydraulic modeling approaches were utilized achieve this objective. The findings revealed that all produced similar watershed boundaries mountain area (Wadi Qaws), except for ALOS-PALSAR, which generated a different boundary from previous reports studies. GDEMs failed accurately delineate drainage one dams, SRTM ALOS-PALSAR. Moreover, ASTER products provided closest estimates ground observations, producing peak discharges 114.1 m3/s 110 m3/s, respectively. For entire encompassing mountain, urban, coastal areas, demonstrated significant differences boundary, streams, outlet location, discharge at outlet. In addition, each GDEM's map was significantly distinct. Overall, results suggest outperformed other area.
