The IWRM impact assessment tools have been and are being applied for following sectors:

Powerplant operation rules, powerplant turbine optimization, reservoir design, dam security, sediment trapping & flushing management, upstream - downstream hydrological analysis, water quality impacts

Nuclear and coal power plants
Coolant intake optimization, coolant impacts, (radioactive) contaminant dispersion, climate change impacts on including plant efficiency

Infrastructure (roads, bridges, dykes, navigational channels, buildings)
Feasibility, design parameter optimization, risk management, environmental impact analysis, climate change proofing

Disaster management – flood & drought
Flood damage assessment, design floods (e.g. 5y/ 10y/ 20y / 50y / 100y), cost & flood benefit analysis, design and operations for reservoirs and detention areas, climate adaptation, early warning systems

Hydrological analysis, irrigation optimization, reservoir design, crop calendars, climate change analysis

Farming systems
Crop calendar optimization, crop suitability, impact analysis of agricultural production on food security, farmer income optimization, climate change adaptation. Utilization of integrated FAO AquaCrop physiological crop model.
