Under the SS Credit, how would one achieve points under the Rainwater Management strategy?

H.W: Design a sedimentation tank to be treat 0.10 m³/sec

Please interpret the following scenario and concisely answer the question at the end: Overland flow, also known as Vegetated Natural Buffer, is an effective water quality treatment best management practice for airside areas at airports. Why is this BMP desirable in this circumstance and what is the primary water quality treatment mechanism?

A lateral sewer is to be designed to receive flow from 30 acres of a city in an area wherethe population density is 150 people per acre. If the average per capita flow rate is assumedto be 100 gpcd, what should be the design flow rate of the lateral, in gpm and cfs?

You are in a 240-acre watershed and receive 7 inches of rain to fall in a 24-hour period, what is the Volmne? You are in a 240-acre watershed and receive 7 inches of rain to fall in a 24-hour period, what is the Surface Water? In the same scenario as questions 26 and 27 with the ground being 60% permeable, what is the the infiltraion? In the same scenario as questions 26 and 27 with the ground being 60% permeable, what is the the Run-off? In the same scenario as questions 26 and 27 with the ground being 30% permeable, what is the the infiltraion? In the same scenario as questions 26 and 27 with the ground being 30% permeable, what is the the Run-off?

A watershed with an area of 4.0 ha has a composite runoff coefficient of 0.60, find the peak rateof runoff for the 5-, 10-, and 20-yr storms. Assume a time of concentration of 15 minutes. Use MTO IDFCurves Finder to find IDF parameters for McMaster University Location

Qoastion 2 Which of the options below best describe the changes to stormwater runoff after an area is developed? Select all that apply increase in peak rate of the runoff O Increase in the velocity of runoff O Increased pollution O Increase in runoff volume increased infiltration increased vegetated cover OIncreased impermeable surfaces Question 3

Runoff data have been collected for a 4-hour storm over a 120 acre watershed as indicated in the table. If the total volume of water infiltrated during the storm was 3.0 Ac-ft and the Phi Index is 0.1 in/hr, sketch the rainfall hyetograph with EVERYTHING labeled appropriately. Also, report the depth and volume of precipitation (in inches and Ac-ft, respectively) for each 1-hour period.

Question 8. [2 Points] Create a 60-minute hydrograph for a 10-acre flat lawn covered with yellow bluestem grass on clayey loam soil and the time of concentration = 20 minutes. A 10-year storm frequency is to be considered. Calculate the volume of the storm runoff.
