Precipitation

Precipitation forms the basis of the water cycle on the Earth. The air is packed with water molecules in the form of moisture or water vapor. This water vapor usually rises to the atmosphere due to density differences. Precipitation represents any form of water, in liquid form or frozen form that forms in the earth's atmosphere. The water vapor up in the atmosphere condenses due to low temperature and it leads to the formation of clouds. The water vapor that forms clouds on account of condensation, is preferably known as cloud droplet. These cloud droplets when become heavy and can no longer sustain the weight of condensed water droplets, they come to the Earth in the form of rain, snow, ice pellets, and hail. Precipitation patterns, evaporation, and condensation are the three parameters that decide the global water cycle, climate change, and weather. Additionally, smoke and dust particles are equally important parameters for precipitation, as they provide the surface area for the water vapors to get condensed and to form water droplets. So they are known as condensation nuclei. The presence of other pollutants in the air also serves as condensation nuclei. Precipitation always results in the pure water supply to earth, as the salt from the seawater does not evaporate with the water.

A rainfall hyetograph is provided for a 6-hour storm event, which occurred over a watershed with an area of 2100-acres (Ac). If the Phi-index is 0.71 in/hr, calculate the volume of runoff (VRO) from the storm (in Ac-ft). Report your answer to the nearest tenths (0.1) place. HINT...the answer should be around the 500-1,500 Ac-ft range (yes, it is a big range if you need to guess). Intensity (in/hr) 2.5 2.0 1.5 1.0 0.5 0.0 0 1 2 3 4 Time (hr) 5 6 7 2

Problem 2. A storm had 3 successive 6-hr intervals of rainfall magnitude of 3.0, 5.0 and 4.0 cm, respectively.

Plot the resulting DRH due to 3 rainfall events, assuming a phi-index of 0.20 cm/hr. • Recall that the phi-index represents the rate of infiltration. • The hydrograph plots RUNOFF rates, where runoff = precipitation - losses. Note that the rainfall magnitude is reported as total rainfall depth in 6 hrs, so convert infiltration as a total for every 6 hr period. b. Assuming a baseflow of 30 m3/s, what are the ordinates of the storm hydrograph?
