2 Section A Theme 4 – Geographical Investigation Answer one question from this section. 1 A group of 6 students observed that a section of the Bukit Batok Canal in the western part of Singapore was refurbished with rain gardens as part of the Public Utilities Board’s (PUB) ‘Active, Beautiful and Clean’ (ABC) Waters Programme. Rain gardens help to manage surface runoff in urban areas in a more sustainable manner, by controlling the quantity and quality of surface runoff to prevent pluvial flooding, through natural filtration and encouraging subsurface conveyance of water into catchments. The students wanted to study the effectiveness of the rain garden project in Bukit Batok by measuring infiltration rates of surfaces adjacent to the canal. Breaking into 2 teams, each team of 3 students concurrently took readings from 10 randomly sampled sites along the segment that underwent refurbishment (as seen in Photograph ‘A’), and 10 randomly sampled sites along the segment that remained unchanged (as seen in Photograph ‘B’). The infiltration readings were taken on two separate occasions over a period of 2 days owing to inclement weather interrupting the fieldwork after readings from 5 sites were sampled. Equipment used for each team: • Double-ring Infiltrometer • Stopwatch • Bottles of water • Printed recording sheets and writing materials • Large scale map of the study area The infiltration readings were plotted into infiltration rate graphs.
