Question

Environmental Engineering Problems: The following prolems ar engineering and risk assessment. Read each problem carefully and show information needed to solve the problems is provided in each supplemental information section at the end of the exam. To receive full credit, please clearly state your rationale and assumptions; include diagrams where appropriate. related to water resources I your work. The statement and in the problem と points) Use a hydrologic mass balance to solve the following: A small watershed is approximately 75 km2. In a given year, the average monthly inflow was 3.5 m'ls and the monthly average outflow was 2.15 m'/s, mainly as the result of runoff. The total precipitation in the watershed was 246 cm and the total evaporation was 98.A cm for that year. The infiltration was estimated to be 16.2 cm for the same year. (10) Estimate the change in storage (in cm) for that year (10) If you are planning to design a small reservoir in the watershed, what is the maximum amount of water that you can withdraw from the watershed in a year to maintain steady state conditions assuming similar conditions (G.e. same inflow, outflow, precipitation, infiltration, and evaporation) prevail for that year? a. b.
