Volume of water passing a fixed reference point per unit time. This is a volumetric variable and is expressed cubic meters/sec or cubic feet/sec.
Dams - Flood impoundment dams are kept empty most of the time. These can mitigate the
effects of flash floods. These dams trap sediment behind dam preventing it from reaching the shoreline for natural beach nourishment (displaced problem). Dams are not especially effective in preventing large, downstream flooding, such as 1993 Mississippi Flood. Actually may cause controversy for residents above and below dam. Dams have a negative impact on the river/fluvial ecosystem both upstream and downstream from the dam site. Those Damned Dams!
The height of the water surface above the gage datum (zero point). Stream stage is the height of the water surface in a stream measured in feel or meters relative to an arbitrary fixed reference elevation point.
