Problem 1. A pine forest is to be cleared for a development in which all the trees on the site will be removed. The IDF curve for the area is given by { = 2819 t+20 Where i is the average rainfall intensity in mm/h and t is the duration in minutes. The storage capacity of the trees in the forest is estimated as 5 mm, the leaf area index is 6, and the evaporation rate during the storm is estimated as 0.3 mm/h. Determine the increase in precipitation reaching the ground during a 30- min storm that will result from cleaning the site.

4-Calculate the amount of rain falling (storm water) on a water shed area, if you know the following: 1- Inlet time of flow = 6 min. 2- Travel (flow) time =7 min. 3- Runoff coefficient = 0.40 4- Water shed area = 10 ha.
Runoff data have been collected for a 4-hour storm over a 120 acre watershed as indicated in the table. If the total volume of water infiltrated during the storm was 3.0 Ac-ft and the Phi Index is 0.1 in/hr, sketch the rainfall hyetograph with EVERYTHING labeled appropriately. Also, report the depth and volume of precipitation (in inches and Ac-ft, respectively) for each 1-hour period.

A Palm Spring golf course has requested a permit to install a 40000 ft2 pond to enhance the beauty of its facilities. Since the evaporation rates are very high in Palm Springs, it is likely they will need to pump a lot of groundwater to keep the pond full. The city has hired you (a water resources engineer) to determine how much water needs to be pumped per year in order to keep the pond filled. There is a small creek that discharges an average of 0.25 m3/s into the pond. The outlet valve from the pond releases an average rate of 0.30 m3/s (to keep the pond from getting stagnant). Precipitation on the pond is 260 mm/year, and the annual evaporation is estimated to be 105 inches/year. The pond will be lined with concrete to prevent any drainage or seepage from the bottom. Using a water balance, what volume (on average) of groundwater (in cubic meters) must be added to the lake each year to keep the pond at a constant level? Draw a schematic of the problem to identify the control volume…

Estimate the total storage requirements assuming 1200 inhabitants and a daily basic water requirement of 90 litre per person. There are a total of 400 houses and a community centre/church, with roof areas 30 m² and 295 m² per building, respectively. For safety, how much additional water should be supplied from other sources during a drought year?
A catchment is idealized as a 25 km × 25 km square. It has five rain gauges, one at each corner and one at the centre, as shown in the figure. G₂ G₁ O G5 GA G3 During a month the precipitation at these gauges is measured as G₁ = 300 mm. G₂ = 285 mm, G₂ = 272 mm, G₂ = 290 mm and G5 = 288 mm. The average precipitation (in mm up to one decimal place) over the catchment during this month by using the Thiessen polygon method is
A drainage basin has a area of 7322 km2. The average annual precipitation for this area is 909 mm. The average surface water flow at the outlet of the catchment is 21.4 x 108 m3/year and the average groundwater flow out of the basin is 94.6 mm/year. Assume trailing zeros are significant if present. Determine the annual average evaporation in mm/year. (give your answer to one decimal place)
A reservoir had a water surface elevation of 110 m above the datum at the beginning of the month. In the same month, the reservoir received an average inflow of 7.5 cms (m3/s) from surface runoff sources. For the same period, the outflow from the reservoir had an average value of 5 cms. Further, in the same month, the reservoir received a rainfall of 180 mm and losses due to evaporation of 5 cm. Assume the area of the lake is 50 km2 acres and assume no contribution from groundwater storage. What is the water surface elevation of the reservoir after the month?
