The second of five Early Warning System components consisting of the processes and facilities necessary to translate incoming data about the threatening event into decisions to alert or warn the population at risk.
Industry:Engineering
Water removed from the ground or diverted from a surface-water source for use. The process of taking water from a source and conveying it to a place for a particular type of use.
Industry:Engineering
A flood which follows within a few hours of heavy or excessive rainfall. A flood of short duration with a relatively high peak rate of flow, usually resulting from a high intensity rainfall over a small area.
Industry:Engineering
The highest level of a contaminant that is allowed in drinking water. MCL's are set as close to the Maximum Contaminant Level Goal as feasible using the best available treatment technology.
Industry:Engineering
Reservoir volume above active conservation capacity and joint use capacity that is reserved for flood runoff and then evacuated as soon as possible to keep that volume in readiness for the next flood.
Industry:Engineering
Rate of flow of water expressed in feet per second or miles per hour. The time rate of displacement of a fluid particle from one point to another. Velocity is a vector quantity that has magnitude and direction.
Industry:Engineering
Adsorptive particles or granules of carbon usually obtained by heating carbon (such as wood). These particles or granules have a high capacity to selectively remove certain trace and soluble materials from water.
Industry:Engineering
The maximum angle with the horizontal at which a sloped bank of soil or rock of given height will stand unsupported. That slope which will sustain a given discharge at uniform critical depth in a given channel.
Industry:Engineering
Computed as the ratio of the flood control pool depth to the depth below the pool, multiplied by the percent of time the reservoir water surface will be within the flood control pool.
Industry:Engineering
An embankment dam composed of zones of selected materials where the permeability of the material increases to the upstream or downstream face from the relatively impermeable core material.
