3 Section A Theme 4: Geographical Investigations 1 You are part of a group of classmates that was tasked to investigate the influence of land use on infiltration rate s in Singapore. The group was divided up into 2 teams of four to measure the infiltration rate at 2 locations simultaneously. In planning the geographical investigati on, the teams ident ified the land use areas by first looking at the land use map of Singapore. For practicality reasons, the teams chose to conduct their study at two sites of different land use - Site A which is a nature park l and within Bukit Timah Nature Reserve and Site B, a built-up residential area in the Dairy Farm Estate. The teams chose to collect data on infi ltration within the different land use areas they had identified. The study was conducted at one accessible point within each survey site. The investi gation was conducted on the Saturday morning of 30 June 2018. The infiltration rate is measured by us ing a set of infiltration rings and by timing the speed at which the water level in the ring falls. The following equipment and materials were used to m easure infiltration rate at the two different land use sites: • Dual-ring infiltrometer co mprising two tin cans, the first about 30 cm tall with a diameter of 15 cm and the se cond smaller tin can about 25 cm tall and with a smaller diameter of 9 cm. Both tin cans have both ends of it removed. • Plentiful supply of water • A ruler • Hammer • Wooden plank • Stopwat
