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.
It can also be caused by heavy snow melt and ice jams. The damage from a river flood can be widespread as the overflow affects smaller rivers downstream, often causing dams and dikes to break and swamp nearby areas. There are two main types of riverine flooding: Overbank flooding occurs when water rises overflows over the edges of a river or stream. This is the most common and can occur in any size channel â from small streams to huge rivers.
