A cofferdam has been built to protect homes in a floodplain until a major channel project can be completed. The cofferdam was built for the 97-yr flood event. The channel project will require 3 yr to complete. What are the probabilities that the cofferdam will not be overtopped during the 3 year (the reliability)? (Please enter the answer with 2 decimals)

Concept explainers

Concepts of Flood Control

Flooding is a temporary overflow of water that submerges or covers the the usually dry land. It can also be defined as the overflow of the excess amount of water that covers a huge area of land which is normally dry.

Question

A cofferdam has been built to protect homes
in a floodplain until a major channel project
can be completed. The cofferdam was built
for the 97-yr flood event. The channel project
will require 3 yr to complete. What are the
probabilities that the cofferdam will not be
overtopped during the 3 year (the reliability)?

WATER RESOURCES ENGINEERING A 6-hour storm event occured in the study basin. You were able to measure precipitiation and infiltration data, but not streamflow. Using the precipitation and and infiltration data and the unit hydrograph, estimate the total streamflow during and after this storm event. Calculate stream flow for each time step until the total streamflow is equal to the baseflow of 35 m3/s. Please refer to attached images of data tables:

As shown in the Google Maps, a 12-inch PVC pipeline (f = 0.019) will be constructed to provide water from the Pomona Water Reclamation Plant (PWRP) to Cal Poly Pomona campus. The pipeline is meant to deliver 2550 gal/min to the proposed development. The total length of this pipeline is 2.34 miles. The elevations at the beginning point and the ending point are 348 feet and 365 feet, respectively. At PWRP, there is a half-open gate valve for water supply shortly after the flow enters the pipeline through the entrance (r/d = 0). Along the pipeline, smooth bends (with vanes, r/d = 8) were utilized to alter flow direction. At each fire hydrant (FH) location, a tee is installed to create a lateral to the fire hydrant. How much residual pressure should be there at the beginning point to ensure the minimum residual pressure of 30 psi at the ending point of this pipeline? Assume a = 1.0 at all locations; temperature is 15°C. Hint: Compute the pipeline velocity, unit head loss, and the residual…
