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

The flow ordinates of a 1- hr UH are as follows:

Calculate the DRH for a two hour Strom in which 4" of excess rain occurs at a constant rate. Also find the area of the basin

A rainfall hyetograph is provided for a 6-hour storm event, which occurred over a watershed with an area of 2100-acres (Ac). If the Phi-index is 0.71 in/hr, calculate the volume of runoff (VRO) from the storm (in Ac-ft). Report your answer to the nearest tenths (0.1) place. HINT...the answer should be around the 500-1,500 Ac-ft range (yes, it is a big range if you need to guess). Intensity (in/hr) 2.5 2.0 1.5 1.0 0.5 0.0 0 1 2 3 4 Time (hr) 5 6 7 2

11- The design storm of water shed has the depths of rainfall of 4.9 and 3.9 cm for the consecutive 1-hr periods. The 1-hr unit hydrograph can be approximated by a triangle of base 6hr with a peak of 50 m³/s occurring after 2 hr from the beginning. Compute the flood hydrograph assuming an average loss rate of 9 mm/hr and constant base flow of 10 m³/s. What are the areas of water shed and its coefficient of runoff?
An effective rainfall of 2 hour duration produced a flood hydrograph peak of 200 m³/s. The flood hygrograph has a base flow of 20 m³/s. If the spatial average rainfall in the watershed for the duration of storm is 2 cm and the average loss rate is 0.4 cm/hour, the peak of 2-hour unit hygrograph (in m³/s-cm up to one decimal place) is
