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.
What Causes Flooding? There are many reasons why floods occur, these can be divided into categories of causes. These are flash floods, storm surge, and dam and levee failures. Flash Floods These types of flood occur with little or no warning. Flash floods can be deadly due to the rapid rise in water levels and the high flow-velocities of the water. There are factors which contribute to the occurrence of flash floods: rainfall intensity, duration, surface condition and topography.
