Izzard formula for the time of concentration in minutes for the plots having no channels, is (where Lo is the length of overland flow in metres and Kp rainfall intensity in cm/hour)
A unit hydrograph is a hydrograph of a rain storm of a specified duration resulting from a run-off of
Pick up the correct statement from the following :
The best unit period of a unit hydrograph, is equal to basin lag divided by
If total run off of a basin of 50 hectares is 0.8 cm, the ordinate of Bernard's distribution graph, may be calculated by the formula (where Q is the discharge in cumecs at the given time)
Pick up the correct statement from the following :
The equation 
which is used for determining the velocity of ground water flow in metres per day is known as
Pick up the correct statement from the following :
While determining the yield of a gravity well by pumping, the depth of water table in two tests wells at distances r1 and r2 from the centre of the main well were found to be s1 and s2 respectively. Assuming the coefficient of transmissibility of the soil as T, the discharge Q may be given by
According to Thiem, the permeability of an aquifer may be obtained from the equation
A well is sunk in an unconfined aquifer having a saturated depth of 100 m. Assuming the equilibrium flow conditions and a homogeneous aquifer and radius of influence to be same, the ratio of discharges at 20 m and 40 m draw downs, is
Phytometer method is generally used for the measurement of
In the estimate of design flood, Dickens assumes that high flood in cumecs, is proportional to catchment area raised to the power
For high flood estimates the average value of the constant C in Dicken's formula Q = CA3/4, is
Pettis formula Q = C (P.B)5/4 cumecs, is based upon
Boston society of Civil Engineer's formula 
in cumecs/square km is based upon
For predicting floods of a given frequency, the best reliable method is
The earthen embankments constructed parallel to the river banks at some suitable distance for flood control, are known as
