A small water shed consists of 1.5 km2 of cultivated area (c=0.20), 2.5 km² under forest (c = 0.10) and 1.0 km² under gross cover (c= 0.35). There is a fall of 22 m in a water course of length 1.8 km. The intensity frequency duration relation for area is given by 8070.2 I= (t+13)0.46 Where I is in cms/hr, T, in years and t is in minimum. Estimate the peak rate of run off for a 25 year frequency.

Situation 01. On June 1, 2015, a reservoir had a water elevation located at Sta 0 + 114.43 in reference to a benchmark set at 0 meters. The area of the reservoir is 5120.23 ha. Given the data below, Inflow 6.20 cms per day Outflow 6.63 cms per day Infiltration Loss 0.01 mm Evaporation 6.12 cm Rainfall 152.20 mm Compute the station of the water elevation at the end of that month.
Compute the diameter (cm) of the outfall required to drain storm water from the watershed described in figure below. Use rainfall intensity = 4 cm/hr. Average velocity of flow is 1 m/s. Other data are for: Area 1: C=0.5, area=0.005 km2. Area 2: C=0.4, area =0.01 km2. Area 3: C=0.7, area=0.015 km2.

A lake data is as follow: the discharge into lake is 1.5m /s the out flow discharge is 3. 1.25m /s, evaporation rate is 23.3 cm/month and the total precipitation was 29.4 cm/month. The average depth in the lake on 1 June was 19m, the average depth on June 30th was 20 m. The surface area of the lake approximately is a. 49 ha b. 59 ha .C 89ha d. 69 ha
uestion No.3 catchment has a net area of 90 ha. After one vear, groundwater table is nonitored, and a sie change is detected. During this year, the average monthly precipitation and evapotranspiration were 20mm and 5mm respectively.

Solve the following questions of hydrology analyze properly and show complete solution.
Q.2 A catchment having an area of 150 km2 has the ø index 0.3 cm/hr. The base flow at the 3 outlet is 10m³/s. One hour unit hydrograph of the catchment area is triangular in shape with a time base of 20 hours. The peak ordinate occurs at 8 hours. If a rainfall of 4.5 cm occurs in 1 hour, then the peak ordinate of the flood hydrograph will be:

9.4. A small farm reservoir behaves as two identical CFSTRs in series. Flow into the reservoir consists of runoff from pasture land having an average BOD, of 50 g/m³ and an average flow rate of 0.5 m³/s. Volume of the reservoir is 2.16 x 106 m³. If k = 0.2 d-¹ and k, = 0.35 d-¹ at 20°C, determine the dissolved-oxygen concentration if the water temperature is 20°C, the inflow is anaerobic, and steady-state conditions exist.
15mm of precipitation fell in Akkaya reservoir in July. At the beginning of July (30 days), the surface area of the lakewas measured as 3 km². There is 9000000 m³ water in the lake before precipitation in July. At the beginning of August, the water volume in the lake was 8500000 m³. During July, Q=100 lt/s of water emerged from the reservoir. The water leaking from the ground is Q=36 lt/s throughout July. The water leaking in the same month is Q=48 lt/s. In July, 30 lt/s of water was drawn from the reservoir for 15 days to i dilate the campus area. However, in the same month, 1/3 of this water leaked and returned to the lake. During this month, the amount of water evaporating in the lake was determined as 110 mm/ m² .Calculate the flow of water coming into the reservoir as lt/s or m³/s.
