Concept explainers

Unit Hydrograph

Hydrology is the science which deals with the study of water on the earth’s surface. The word Hydrograph is derived from the word hydro which means water. Hydrograph is basically a graph in which the discharge is plotted against the time interval at a specific point in a river or other channel. In a hydrograph, the discharge is plotted along the y-axis and time interval is plotted along the x-axis. Hydrograph is used to estimate the runoff. The variations in discharges with the change in time is shown by a hydrograph. It was revealed that the total discharge at an outlet increases with time by a kinematic wave model.

i) Based on the unit hydrograph in Table Q4b, construct its S-Curve and develop a 1-hour Unit hydrograph. ii) Based on the unit hydrograph in Table Q4b, construct a new natural hydrograph that can be produced by a series of effective rainfall of 2.5cm, 1.1cm, and 0.3cm that occurred at one-hour intervals between one event and another.
11- The design storm of water shed has the depths of rainfall of 4.9 and 3.9 cm for the consecutive 1-hr periods. The 1-hr unit hydrograph can be approximated by a triangle of base 6hr with a peak of 50 m³/s occurring after 2 hr from the beginning. Compute the flood hydrograph assuming an average loss rate of 9 mm/hr and constant base flow of 10 m³/s. What are the areas of water shed and its coefficient of runoff?
Need ASAP! Thank you!
An effective rainfall of 2 hour duration produced a flood hydrograph peak of 200 m³/s. The flood hygrograph has a base flow of 20 m³/s. If the spatial average rainfall in the watershed for the duration of storm is 2 cm and the average loss rate is 0.4 cm/hour, the peak of 2-hour unit hygrograph (in m³/s-cm up to one decimal place) is
A 20-minute rainfall event occurred at a small catchment (without any base flow), which has 2 branch rivers (or tributaries) with individual sub-catchments. This storm generated a triangular runoff hydrograph with peak flow of 139 L/s at the catchment outlet. Base of the triangular hydrograph was 1 hr 12 minutes. The rainfall distribution and other relevant data is given in Table 1. Assume that the rainfall was uniform over the subcatchments. Calculate the followings: i) Total rainfall volume fallen on the catchment. ii) Total runoff volume generated from the catchment during this rainfall event. iii) Average runoff coefficient for the whole catchment for that particular rainfall event.
