| dc.description.abstract | Hydrological modelling and urban floods have a strong
relationship as flood management is based on hydrological
calculation. GIS assists this relation by providing an easy
environment to carry out difficult and time-consuming steps of
hydrological calculations. However, when developing automated
GIS tools for the above process, there are no guidelines available
to manage the software project easily. Then developing a
comprehensive guideline requires to clearly understand of the
role of GIS in the urban flood and hydrological modelling
relation. The present work carried out an in- depth study on;
flood, land management, hydrological modelling and GIS
assistance to hydrological modelling to understand the role of
hydro GIS tools in urban flood management. It used the semisystematic
literature review method to review the gathered
knowledge. Through the analysis, it found a close relationship
between flood and land management, specially in urban areas.
Further, it found that now GIS is assisting in performing the major
functions of hydrological models than the inception, and the
HydroGIS term has been introduced to identify the software tools
that assist flood management through hydrology modelling.
Further, it has been understood that HydroGIS tools are
employed in local-level flood management activities and utilised
by non-technical decision-makers for day-to-day activities. Hence
the HydroGIS tools can be introduced to the local level
authorities as an interface to perform complex hydrological
processes when land management decision-making. | en_US |
