CE 451 Water Resource Engineering 03/29/2010 Home Work #7 7.6. The mass curve of available water during the critical dry period at a given storage reservoir is as shown in the following figure. (a) What continuous constant yield (in acre- feet per year) is possible with a reservoir having storage capacity of 500 acre-ft? (b) What storage capacity (in acre- feet per year) is required for a constant yield rate of 140gpm? 7.10. The following table gives monthly flows, pan evaporation, rainfall, and demand rates for a critical 12-month period at a proposed reservoir site. Prior water rights require the release of natural flow or 8 cfs, whichever is least. Assume that the average reservoir area is 1500 acres and that the runoff coefficient for the land that will be flooded is 0.3.

Unformatted text preview: what reservoir capacity is required? If the previous year was substantially similar to one given in the table, is there sufficient water to meet the demand? 7.17. The suspended sediment, in tons per day, conveyed by a certain stream to the flow rate, in cubic feet per second, by Eq.(7.2) with k=0.004 and n=3. Compute an estimate of the amount of suspended sediment passing the gaging station during the rising limb of the hydrograph shown in the following figure. 7.27. Analysis of westerly winds at a given point reveals the following relation between wind speed and duration: Determine the significant wave heights for westerly winds with fetches of 1,2,3,5, and 7 km....
