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.
Floods cause disasters, but they can also be beneficial. Whenever a river overflows its banks, it dumps sand, silt and debris that it has carried downstream onto the surrounding land. After the flood waters move away, the soil is more fertile, because of the organic matter and minerals in this material.
