The amount of rainfall recorded for one of the years is given below: Rain gauge station | || ||| IV V Annual rainfall in cm 100 120 190 95 125 Find the required optimum number of non-recording and recording rain gauges for this watershed. Assume an error of 10% in the estimation of mean rainfall.Working on discharge and peak flow for hydrology. I did some data analysis and need to know what is going on with these rivers. I am confused by Average depth of runoff produced across the basin (meters/yr) vs How many times bigger a typical flood is than baseflow, a measure of flashiness and what is going on
- A rainfall hyetograph shows a) the total volume of rainfall for a storm event; b) the cumulative volume of rainfall with time over the duration of a storm event; c) the variation of rainfall event over a watershed; d) the intensity of volume of rainfall as a function of time; e) none of the aboveRunoff 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.The hyetograph in the figure corresponds to a rainfall event of 3 cm.
