The Impacts of Land Use Changes in Urban Hydrology, Runoff and Flooding: A Review ()
ABSTRACT
The
issue of Land Use (LU) change has received considerable critical attention because it is one of the most significant factors caused by
human activities worldwide. Recent critical changes in this direction have
affected urban hydrology. LU change affects water resources and hydrological
characteristics such as runoff and urban flooding. The development of LU causes
a rapid increase in impermeable surfaces, increasing the flooding rate. LU also
plays a vital role in extending water drainage, groundwater intrusion, and
flooding during and after rainfall. This
paper aims to investigate LU change impacts on runoff and urban
flooding. This review focused on most articles, conference papers, and book chapters published in SCOPUS, including Google Scholar.
The study was limitation to the last published from 2017-2021 and also extended
some published theories for different years published. In addition, in the
short and long term, the development of LU affects the environment, and most
factors are involved at a catchment level. However, there is a strong
relationship between human activities at the catchment level and runoff. The study concluded that LU strongly influences
topography and the landscape in arid, semi-arid, and humid zones. This
is why runoff and water distribution happen in urban areas. Furthermore, this
study found that built-up area is a critical factor that increases
urban flood risk, especially in lowlands along floodplains. It is common for the frequency of
floods to become more severe due to a rapid increase in impervious surfaces
brought on by urbanisation, increasing
runoff. The review concludes that runoff affects by catchment size and
its condition. Finally, humans can be reduced runoff and flood risk with a
sensibility strategy.
