WebA spillway must remain unobstructed to maintain its flow capacity. Obstructions such as fish screens, walkways, vegetation, and bridge piers should be cleared from the spillway inlet. Loss of flow capacity could cause the dam to overtop and fail. WebNov 21, 2016 · An LED is a diode, and all diodes have reverse current. At the most fundamental level, this is explained in Shockley-Reid-Hall theory - the states that allow carrier recombination also cause carrier generation (the inverse process). In reverse bias, the carriers separate and are seen as current on the external terminals.
