Access the URL http://waterdata.usgs.gov/pa/nwis/inventory/?site_ no¼01447500 and download the historical series of mean daily discharges and the reduced series of annual peak discharges, of the Lehigh River at Stoddartsville, both for the period of record. Extract from the downloaded daily flows the reduced series of annual maximum mean daily discharges, on the water-year basis. Plot on the same chart the two reduced series of annual peak discharges and annual maximum mean daily discharges, against time. Explain what causes their values to be different. Describe the possible disadvantages and drawbacks of using the reduced series of annual maximum mean daily discharges for designing flood control hydraulic structures?
