All concepts →Following statements are made with respect to the mass curve of rainfall: (I) Slope at a point on the curve can be positive. (II) Slope at a point on the curve can be zero. Which o...
The mean rainfall over a catchment has to be estimated. The data for four rain gauges located in and around the catchment is listed in the table. Which one of the following stateme...
A 12-hour storm occurs over a catchment and results in a direct runoff depth of 100 mm. The time-distribution of the rainfall intensity is shown in the figure (not to scale). The $...
A two-hour duration storm event with uniform excess rainfall of 3 cm occurred on a watershed. The ordinates of streamflow hydrograph resulting from this event are given in the tabl...
The hyetograph in the figure corresponds to a rainfall event of 3 cm. If the rainfall event has produced a direct runoff of 1.6 cm, the φ-index of the event (in mm/hour, round off...
The annual average rainfall in a tropical city is 1000 mm. On a particular rainy day (24-hour period), the cumulative rainfall experienced by the city is shown in the graph. Over t...
During a storm event in a certain period, the rainfall intensity is 3.5 cm/hour and the Φ-index is 1.5 cm/hour. The intensity of effective rainfall (in cm/hour, up to one decimal p...
The total rainfall in a catchment of area 1000 km², during a 6 h storm, is 19 cm. The surface runoff due to this storm computed from triangular direct runoff hydrograph is 1×10⁸ m³...
Rainfall depth over a watershed is monitored through six number of well distributed rain gauges. Gauged data are given below Rain Gauge Number 1 2 3 4 5 6 Rainfall Depth (mm) 470 4...
A 1-hour rainfall of 10 cm has a return period of 50 years. The probability that 1 hour of rainfall 10 cm or more will occur in each of two successive years is
An isohyet is a line joining points of
During a 6-hour storm the rainfall intensity was 0.8 cm/hr on a catchment of area 8.6 km 2 . The measured runoff volume during this period was 2,56,000 m 3 . The total rainfall was...
