2 8813/1/2017/Preliminary Examinations/QP Section A Theme 3: Geographical Investigation 1 You and a group of classmates were tasked with undertaking a fieldwork investigation at two contrasting river channels to ascertain the flood risk at the sites shown in Resource 1. River A is located in a forest reserve. River B is a managed river channel. The group was divided up into teams of four to measure river velocity and wetted perimeter of each river. 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 March and were given 4 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: • Oranges • Tape measure • Stop watch The time taken for the floating object to cover a pre-determined distance, defined by the position of 2 students standing by the side of the river, was recorded. At River A, the group found that the floating object was often obstructed by fallen trees or debris in the river. The data collected was recorded using a data collecti
