Abstract

Infiltration basin is constructed to capture and store the excess water while it infiltrates through the basin's floor and sides. The infiltration basins are storm water control measures (SCMs) widely employed for urban storm water management. For this study performance of Infiltration Basin, the dimension of infiltration basin constructed is 1 m width and lm long (Imxlm). The infiltration basin is enclosed with the Perspex to ensure the area is undisturbed. Infiltration can be defined as the rate of water entering into the soil because of the act of the gravity and capillary action. The unit used to measure the infiltration rate is cm/hr. The method to determine the infiltration rate are by using double ring infiltrometer and by direct method. The location has been selected as the study area is near the Hydraulic Laboratory Faculty of Engineering UPM. Before starting the infiltration rate test, soil samples have been gathered and analysed in laboratory using the sieve analysis test. The type of soil sample underlying play very important part in the performance of infiltration rate. The infiltration rate test is tested under two condition which is under natural soil condition and under modified soil condition with and without surface cover. Under modified soil condition, the natural soil is remove and fill with the three types of soil composition which is gravel, filler and natural soil in a certain depth. The analysis indicated that, the rate of infiltration is high at the beginning. Then, it decreases rapidly in the initial stages and slowly till it approaches a nearly constant rate depending upon the type of the soil. The rate of infiltration with the surface cover is higher compare with the rate of infiltration without surface cover. Besides that, the rate of infiltration under modified soil condition is higher compared to rate of infiltration under natural soil composition.
