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.

WATER RESOURCES ENGINEERING A 6-hour storm event occured in the study basin. You were able to measure precipitiation and infiltration data, but not streamflow. Using the precipitation and and infiltration data and the unit hydrograph, estimate the total streamflow during and after this storm event. Calculate stream flow for each time step until the total streamflow is equal to the baseflow of 35 m3/s. Please refer to attached images of data tables:

Q1) During a storm , the hourly rainfall data was as follows: 0 1 2 3 4 5 6 7 8 9 Time (hrs) Rainfall (mm/hr) | 0 | 20 | 25 45 30 10 10 | 15 10 0 1) plot the hyetograph 2) calculate and plot Mass Curve Ordinate.
A double-mass curve is a graph of the cumulative catch at the rain gage of interest versus the cumulative catch of one or more gages in the regions that have been subjected to similar meteorological occurrences and are known to be consistent. The annual rainfalls of gage A,B, C and D are given in table below. Gage D was permanently relocated after a period of 3 years (at the end of 1988). Adjust the recorded values from 1986 through 1988 of gage D using double mass curve with the assumption that the other gages are consistent. Give your answers for the adjusted data in order (1986, 1987, 1988). Give your answers rounded off to the nearest hundredths. Submit your solution and the double - mass curve for both on the folder provided.
