Develop a spreadsheet using the Modified Puls method to route runoff through the specified pond configuration: Storage - At a stage of 0 ft (brim full), the pond has an area of 1 acre. From a stage of 0 ft to a stage of 3 ft, the pond increases to an area of1.5 acres. From a stage of 3 to 5 ft, the pond increases to an area of 2.25 acres. The stage should not increase above 5 ft Hint: develop an equation for this stage-area relationship for use in spreadsheet Hint: After areas are calculated for each stage, they must be converted to storage iven, see attached spreadsheet The pond has an outlet structure with a 6 inch orifice with the invert set at a stage of 0 The pond has a weir set at a stage of 2 that is 6 feet long Change int5 min Deliverables a) Draw a cross section of the pond showing the changes in pond size as the stage increases. Include a cross section of the outlet structure showing the two outlets set at the correct stage b) Develop a stage / storage relationship for the pond from a stage of 0 to 5 ft. c) Develop a stage / discharge relationship for the pond from a stage of 0 to 5 ft d) Develop a graph showing the relationship between outflow and 2S*/dt + O+ e) Use the attached table as a guide to route the given inflow hydrograph through the system (note, continue the routing until outflow stops or recedes to a very lovw eve f) Graph the inflow and outflow hydrographs on top of one another *provide items b, c, d, e and f as tables or graphs as appropriate
