Problem 4.3. By rational method, determine the design peak runoff for a 50-year return period. The watershed consists of 50-ha (120-ac), one third in rotation meadow and the remainder on row crops on the contour. The hydrologic soil group is B and the time of concentration is 30 min. The watershed is at your present location.
Subject: Hydrology Give me right solution Determine the 10-year period peak runoff for 80 hectare watershed having a runoff coefficient of 0.4. The maximum length of flow of water is 610 meters and the fall along this path is 6.0 meters. The rainfall intensity for that return period is 101.25 mm/hr having duration equal to the time of concentration.
a) Calculate the peak runoff rate of the watershed whose area is 600 ha & the rainfall intensity is given 2.5cm/hr. Take Runoff coefficient C = 0.18
Q7: A discharge of 0.15 cumecs is supplied into a canal at the head and 0.1 cumecs is delivered to field having an area of 1.5 hac. The Irrigation is started at a moisture extraction level of 60% of the available moisture and then extends for 10 hours. Determine the following efficiencies: water conveyance, water application, water storage, and water distribution. The following information are known: effective depth of r.z. = 1.7 m, runoff loss in the field = 425 m', water penetration depth varies linearly from 1.7 m at the head end of the field to 1.1 m at the tail end, W.H.C. = 25cm/m depth of soil.
