- Company Profile:
A detailed graphic delineation (representation) of natural and man-made features of a region with particular emphasis on relative position and elevation.
Industry:Energy
A gate on the crest of a spillway to control the discharge or reservoir water level.
Industry:Energy
A method in which the chance of occurrence of the variable involved is ignored and the method or model used is considered to follow a definite law of certainty, and not probability.
Industry:Energy
The magnitude of an earthquake measured as the common logarithm of the resultant of the maximum mutually perpendicular horizontal displacement amplitudes, in microns, of the 20-second period surface waves.
Industry:Energy
The water immediately downstream from a dam. The water surface elevation varies due to fluctuations in the outflow from the structures of a dam and due to downstream influences of other dams or structures. Tailwater monitoring is an important consideration because a failure of a dam will cause a rapid rise in the level of the tailwater.
Industry:Energy
A measure of the likelihood and severity of adverse consequences (National Research Council 1983). Risk is estimated by the mathematical expectation of the consequences of an adverse event occurring, i.e., the product of the probability of occurrence and the consequence, or alternatively, by the triplet of scenario, probability of occurrence, and the consequence.
Industry:Energy
Hydraulic flow routing based on the solution of the St. -Venant Equation(s) to compute the changes of discharge and stage with respect to time at various locations along a stream.
Industry:Energy
A federally established network of commercial radio stations that voluntarily provide official emergency instructions or directions to the public during an emergency.
Industry:Energy
The magnitude of an earthquake measured as the common logarithm of the maximum displacement amplitude (microns) and period (seconds) of the body waves.
