9751/PRELIMS/JC2/MJC/2017 2 Section A Theme 4 – Geographical Investigation 1 Your class of 8 H2 Geography students were tasked to undertake an investigation on two contrasting river channels to ascertain the flood risk in these locations associated with the nature of the channels at each site. The class was divided into teams of four to measure river velocity and wetted perimeter of each river. One site (River A) was along a river in a nature reserve. The other site was along River B, a managed river channel next to an urban expressway. Discharge is calculated by multiplying the cross sectional area of the channel by the velocity of the water. Your team took measurements on two consecutive Tuesdays in September and were given four hours between 10 a.m. and 2 p.m. at each site to complete the river velocity and wetted perimeter measurements. Teams were each given the following equipment to gather the primary data on river velocity: • Tennis balls (floating object) • Tape measure • Stop watch The time taken for the floating object to cover a pre-determined distance defined by the position of the two students standing by the side of the river was recorded. At river A,
