Estimate the amount of rain storage (in inches) in a 6-acre parking lot using the following rainfall and runoff data for one hour period. Rainfall = 0.48 inches, evaporation = 0.31, rainfall excess = 6 ft3/s measured at the outlet of the parking lot.
a storm of 3 hours duration has rainfall intensities of 30 mm/h for the first hour, 50 mm/h for the second hour, and 20 mm/h for the final hour. the initial infiltration rate, f0, and the terminal infiltration rate, fc, are 22 mm/h and 5 mm/h respectively. if the excess rain is equal to 70% of the total rain, calculate the value of the decay constant, k, in the hortons's model shown below:
To determine the daily evaporation at Taal lake, a USWB Class A evaporation pan is maintained. The water level in the pan is 200mm at the beginning and is observed every day. Water is added if the water falls to about 17.5cm to the same depth during the first day. Estimate the daily pan evaporation for the 14-day period for which readings are summarized in the following table.

Please provide an explanation for evry formula and solution. And be clear with your answer. In 1997, Upper Grand watershed near Maputi, Bukidnon with an area of 4350 sq.km received 77.7 cm of precipitation. The average rate of flow measured in the Grand River, which drained the watershed, was 39.6 cu.m/s. Infiltration was estimated to occur at an average rate of 9.2 x 10-7 cm/s. Evapotranspiration was estimated to be 45 cm/yr. What is the change in storage in the watershed in cm/yr. Also, calculate the runoff coefficient for this watershed.
