What is the worst case scenario result of stormwater runoff? (Page 217) - ANSWERThe worst case for stormwater runoff would be pollution and loss of life. What is a dry well? (Page 230) - ANSWERA dry well is an underground structure that disposes unwanted water such stormwater by recharging an aquifer. What is meant by the term: flow attenuation? (Page 230) - ANSWERWhat is meant by the term flow

What is the primary consequence of surface changes? - ANSWERdeveloped sites lose much of their natural storm water storage capacity. The loss of vegetation, organic litter, and changes in surface characteristics, such as roughness and perviousness, result in the rapid conversion of rainfall to storm water runoff. All storm water management practices must be what (3) things? - ANSWER- site specific - region specific - climate specific Define subsurface runoff - ANSWERis storm water that i...

What are the three criteria to consider when determining if storm water discharge coverage is needed under the National Pollutants Discharge Elimination System (NPDES) industrial storm water permits? - ANSWER1. The industry is identified in the federal storm water regulations by SIC code or narrative description 2. There is a point source discharge of storm water to surface waters of the state 3. There is a potential for exposure of industrial materials or activities to storm water runoff T...

National Electrical Code metric units of measurement are provided in accordance with which system standard? Select one - ANSWER The horsepower rating of a controller should be which of the following? - ANSWER Which factor would increase the inductance in an AC circuit if all other factors were held constant? - ANSWER A 2-Ohm resistor and a 5-Ohm resistor are wired in series. If the 2-Ohm resistor is losing 18 watts of power, how much electrical current is flowing through the 5-Ohm resi...
