This study investigates the relationship between hydrological
factors and waterlogged regions, emphasizing the critical role
of robust urban drainage systems in reducing urban flood
risks and improving urban health. Using satellite data and
GIS technologies, the study revealed a strong positive correlation
(r = 0.65, p < 0.01) between the Topographic Wetness
Index (TWI), Land Surface Temperature (LST), and turbidity.
Additionally, the Normalised Difference Water Index (NDWI)
exhibited an upward trend from 2015 to 2022, indicating a
15 % increase in stagnant water. Notably, waterlogged areas
were most vulnerable to environmental stress between
October and December. The research highlights that areas
with high TWI values have a statistically significant association
(p < 0.05) with increased disease transmission risk due to
stagnant water. The findings underscore the impact of landuse
changes and precipitation patterns on urban hydrology
and emphasize the necessity for efficient urban drainage
systems to safeguard public health.
