List of activities which could be performed by avatars (students)
| Nr | Activity | Role |
| 1 | Measuring levels island and water. Draw a cross-section of the island | |
| 2 | Measuring a cross-section at a channel , ditch or river. Based on this information the student can calculate : wetted area and hydraulic radius. | |
| 3 | Measuring the velocity at cross-section at a channel , ditch or river. Combined with the area, the discharge can be calculated | |
| 4 | Calculate the Energylevel based on water level and velocity at cross-section at a channel , ditch or river | |
| 5 | Decide on the roughness coefficient (manning) based on the structure (vegetation) at a channel , ditch or river | |
| 6 | Calculate (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. | |
| 7 | Schietend of Stromend water (froude) | |
| 9 | Turbulente of laminaire stroming (reynolds) | |
| 8 | Measuring waterlevels in the length of a channel , ditch or river. Calculate velocity based on energy slope, hydraulic radius and roughness coefficient | |
| 9 | Advanced. 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. | |
| 10 | At 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. | |
| 11 | At 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. | |
| 12 | At a long crested weir. | |
| 13 |
Calculate pressure on a object below surface (pascal)
