Gce Model Questions Vol1 2023 Geography Question 34
Practice objective / multiple choice question 34 from the 2023 Gce Model Questions Vol1 Geography examination.
A catchment area of \(25\ \text{km}^2\) receives a uniform rainfall of \(30\ \text{mm}\) in one hour. The runoff coefficient for the basin is \(0.6\). (i) Calculate the total volume of runoff (in cubic metres). (ii) Using the rational method \(Q = C I A\), where \(I\) is the rainfall intensity in metres per second and \(A\) the catchment area in square metres, determine the peak discharge \(Q\) (in \(\text{m}^3\text{s}^{-1}\)). (iii) If a discharge of \(150\ \text{m}^3\text{s}^{-1}\) would cause severe flooding, assess the flood risk for this storm.
