List of activities by avatars

List of activities which could be performed by avatars (students)

NrActivityRole
1Measuring levels island and water.
Draw a cross-section of the island
2Measuring a cross-section at a channel , ditch or river. Based on this information the student can calculate : wetted area and hydraulic radius.
3Measuring the velocity at cross-section at a channel , ditch or river. Combined with the area, the discharge can be calculated
4Calculate the Energylevel based on water level and velocity at cross-section at a channel , ditch or river
5Decide on the roughness coefficient (manning) based on the structure (vegetation) at a channel , ditch or river
6Calculate (at cross-section at a channel , ditch or river) the slope of the energyline based on manning. Info needed : velocity, roughness coefficient and hydraulic radius.
7Schietend of Stromend water (froude)
9Turbulente of laminaire stroming (reynolds)
8Measuring waterlevels in the length of a channel , ditch or river. Calculate velocity based on energy slope, hydraulic radius and roughness coefficient
9Advanced. In a cross-section at a channel , ditch or river the velocity is different, depending on the distance to the “wall”. Student measures at different locations in the cross section and calculates the average velocity.
10At a short crested weir in a channel , ditch or river. Measure waterlevel upstreams and downstreams. Measure velocity upstreams. Measure crestlevel. Decide (based on calculation) if crest is submerged or freeflow.
11At a short crested weir in a channel , ditch or river. Measure crestlevel, width crest, waterlevel upstream and downstream, velocity upstream. Decide on crestcoefficient. Calculate discharge at weir.
12At a long crested weir.
13
