Statement of Purpose of Investigation
The purpose of this study is to measure the infiltration rate of four (4) sites which were visited on our field trip to Cedros. Site 1 being the environment disturbed by man, soil compacted by actions of man and animals. Site 2 being the environment waterlogged, because of the mangrove present. Site 3 being the environment undisturbed by man, with vegetation present.
Methodology 1. 61’S geography class attended a field trip to Columbus Bay, Cedros to carry out investigations on the infiltration rate at the four (4) sites. 2. A piece of PVC with a diameter of 5 inches was cut to a length of 15 inches. This PVC was prepared offsite. 3. The PVC was then hammered approximately 5 inches into the ground using a piece of 2x4 wood and a hammer. The wood was placed across the PVC and hammered to prevent the PVC from breaking. 4. After hammering the PVC, a 30cm ruler was placed inside the PVC pipe. 5. A bucket was filled with water. The PVC was then filled with water up to the 20cm mark. 6. A stop watch was then used to record the time after the water being filled to the 20cm marking. 7. The PVC was topped up every 2 minutes by aid of the stopwatch. 8. The water level went down gradually and was observed and recorded. Data was collected and placed into a table.
