Baseflow definition

Baseflow means the portion of streamflow that is not due to storm runoff but is the result of groundwater discharge or discharge from lakes or similar permanent impoundments of water.

Baseflow. " means the means the flowrate of water through the facility that does not include stormwater runoff.
View Source
Baseflow means ongoing small flows in rivers and creeks being principally supplied from groundwater (rather than immediately running off from rainfall). Usually insignificant when peak flows are being evaluated, but can be significant in evaluating the final shutdown of dam releases at the conclusion of the Flood Event;

More Definitions of Baseflow

Baseflow means a sustained low flow in rivers during dry or fair-weather conditions and includes contribution from delayed interflow and groundwater discharge;
View Source
Baseflow means that quantity of streamflow contributed by ground water sources. It is estimated by employing a hydrograph separation method whereby long-term streamflow records are reconstructed so that the majority of stormwater flows are subtracted from those records to theoretically arrive at the ground water contribution to the stream, or through other methods approved by the Department.

  • Flowgate means a representative modeling of facilities or groups of facilities that may act as potential constraint points.

  • Best available control technology (BACT) means an emissions limitation (including a visible emission standard) based on the maximum degree of reduction for each pollutant subject to regulation under CAA which would be emitted from any proposed major stationary source or major modification which the Department, on a case-by-case basis, takes into account energy, environmental, and economic impacts and other costs, determines is achievable for such source or modification through application of production processes or available methods, systems, and techniques, including fuel cleaning or treatment or innovative fuel combustion techniques for control of such pollutant. In no event shall application of best available control technology result in emissions of any pollutant which would exceed the emissions allowed by any applicable standard under 7 DE Admin. Code 1120 and 1121. If the Department determines that technological or economic limitations on the application of measurement methodology to a particular emissions unit would make the imposition of an emissions standard infeasible, a design, equipment, work practice, operational standard, or combination thereof, may be prescribed instead to satisfy the requirement for the application of best available control technology. Such standard shall, to the degree possible, set forth the emissions reduction achievable by implementation of such design, equipment, work practice or operation, and shall provide for compliance by means which achieve equivalent results.

  • Best available control technology means best available control technology as defined in section 169 of subpart I of part C of title I of the clean air act, chapter 360, 91 stat. 740, 42 U.S.C. 7479.
