Overview
Hydrological Modeling plays a vital role in understanding the water cycle and predicting key hydrological processes such as rainfallrunoff, evapotranspiration, and groundwater flow. This becomes
increasingly important in the face of growing challenges associated
with large scale land use changes and climate change impacts. Free
and Open-source Hydrological modeling tools such as HEC-HMS and
SWAT, along with GIS software like QGIS and programming
language like Python, have democratized access to tools for water
resources planning, management and conducting research. These
free tools are not only offer cost-effective solutions but also allow
for customization, enabling users to extend their functionality.
Further, they come with community support for troubleshooting
assistance and accessing valuable learning resources.
