The water balance

Factors affecting river discharge: the storm hydrograph

The long profile – changing processes: types of erosion, transportation and deposition, types of load; the Hjulstrom curve.

Valley profiles – long profile and changing cross profile downstream, graded profile, potential and kinetic energy.

Changing channel characteristics – cross profile, wetted perimeter, hydraulic radius, roughness, efficiency, and links to velocity and discharge.

Landforms of fluvial erosion and deposition – potholes, rapids, waterfalls, gorges, meanders, braiding, levees, flood plains and deltas.

Process and impact of rejuvenation – knick points, waterfalls, river terraces and incised meanders.

Magnitude-frequency analysis of flood risk.

Physical and human causes of flooding – two case studies of recent flooding events should be undertaken from contrasting areas of the world.

Impact of flooding – two case studies of recent flooding events should be undertaken from contrasting areas of the world.

Flood management strategies – to include hard engineering – dams, straightening, building up of levees, diversion spillways, and soft engineering – forecasts and warnings, land use management on floodplain, wetland and river bank conservation and river restoration.
