An absorbing dynamometer acts as a load that is driven by the prime mover that is under test (e.g. Pelton wheel). The dynamometer must be able to operate at any speed and load to any level of torque that the test requires.
Other factors which may contribute to flooding include: 1  volume, spatial distribution, intensity and duration of rainfall over a catchment; 2  the capacity of the watercourse or stream network to convey runoff; 3  catchment and weather conditions prior to a rainfall event; 4  ground cover; 5  topography; and. 6  tidal influences.
Human Causes of Floods 1.Deforestation Large areas of forests near the rivers have been cleared. The lands are used to make room for settlement, roads and farmland. Less vegetation protects the soil, the soil is quickly lost to rivers and the sea.This raises the river bed, so the river overflows its banks easily.
