Watershed Hydrology

By Prof. Rajendra Singh | IIT Kharagpur

Learners enrolled: 1070 | Exam registration: 225

ABOUT THE COURSE:
Watershed Hydrology is the branch that focuses on studying water flow and storage on the Earth's surface, such as in rivers, lakes, and wetlands. It involves analysing various processes that influence surface water, including precipitation, evaporation, infiltration, and runoff. Understanding watershed hydrology is essential for managing water resources, assessing flood risks, and maintaining water quality for human consumption and environmental preservation. Hydrologists can develop models to predict and mitigate the impacts of floods, droughts, and environmental changes on water availability and ecosystems by analysing the interactions between various landforms, soils, vegetation, and climate within a watershed. Hydrologists use various tools and techniques to monitor and model the movement of surface water, allowing for informed decision-making and sustainable water management practices.

INTENDED AUDIENCE: Students studying Agricultural Engineering, Environmental Science, Hydrology, Civil Engineering, or related disciplines at the undergraduate or early graduate level. Professionals in water resources management, environmental consulting, or government agencies are involved in water management and conservation.

INDUSTRY SUPPORT: Water Resource Management Agencies, Environmental Consulting Firms,Civil Engineering and Infrastructure Companies, Agriculture and Irrigation Industries, Environmental NGOs, Urban Planning and Development Firms
