UNDERSTAND AND
IMPLEMENT IWRM TO
CATCHMENT 177
WFM 6303:
Integrated Water Resources Management
Course Project

2. Integrated water resources management
(IWRM)■ Sustainable development
■ Allocation of water resource use
■ Monitoring of water resource use
■ In the context of social, economic and environmental objectives
Objective
■ Situation analysis
■ Assess the degree to which IWRM principles are currently applied
■ Develop/improve upon a Water Management Plan by incorporating IWRM
principles
