(Hydrology)List the type of precipitation received in your area for different seasons. Explain why one type of precipitation is predominant in a given season?Subject: ( Hydology and water Resources management ) Question no 1 What are different forms of precipitation? Which of them are of significance to a civil engineer ? Explain : (i) a method for estimating the missing rainfall data at a station in a basin. (ii) Define 'rain-gauge density' and explain how you would determine the optimum number of rain-gauges to be erected in a basin.
- According to the rainfall records for a city, we have obtained the probabilities of receiving more than 500 mm of rain in four seasons (see the table below). If a seasonal recorded rainfall depth is found to be more than 500 mm, what are the probabilities of this rainfall record for four seasons? Comment benefit of using this observed rainfall record.
