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.
Flash flooding â a flood that occurs within 6 hours of excessive rainfall and that poses a threat to life and/or property. Ice jams and dam failures can also cause flash floods. River flooding â any high water flow, overflow, or inundation event which is threatening lives and property along main stem rivers.
