Summary
Target user 1: software provider/DSS-provider
Target user 2: water authority Ouagadougou
Pre-condition: Software provider has Mike11-NAM and SOBEK-CF model available. Surrounding catchments of the White Volta are modelled with NAM, the river with SOBEK-CF.
Target: the authority wants a tailored decision support system to change the land use in the catchments and assess the impact on peak flow.
Success scenario = happy water authority
- start DSS-application and open Ouagadougou project file
- system shows the background map
- on top of the map the following model features are shown: river stretch (as modelled in SOBEK-CF), catchments (as delineated in NAM), gauging stations (as available in SOBEK-CF)
- the user selects the Ouagadougou gauging station to look at a graph of the peak flow as modelled in the base reference
- the user is unhappy (peak flow is too high) and opens a graph with the longitudinal profile view to understand how the flow builds up along the river
- after analysing the profile, the user has decide where he wants to change land use in order to reducte the peak flow
- the user creates a new scenario and
- modifies land use parameters
- right-click catchment and modify land use parameters
- rerun the models
- saves the modifications and the results
- modifies land use parameters
- the user opens the graph display to look at the peak flow at Ouagadougou gauging station
- the user opens the longitudinal profile display to look at an animation of the flow building up along the river
