This modeling was carried out to see the characteristics of water infiltrated through two different media types by considering the characteristics of the infiltration ability of each media. The media in the first layer is pervious concrete, while the media in the second layer is clay silt. The model is made to represent the application of pervious concrete as a channel base. Pervious concrete is generally used for road pavement. In developing the effectiveness of the application of pervious concrete, water infiltration characteristic was observed using a modeling box which has an area of 80×20 cm, with a thickness of 7 cm of the pervious concrete plate and a soil layer of 20 cm thickness underneath. The discharge in the modeling is based on 10 years of rainfall. The flow of water is regulated by a flow meter within two hours of observation. The description of soil conditions, as well as contours and cross-sectional characteristics of the channel, was taken based on the condition of one of the existing drainages located at Bandung State Polytechnic. The average infiltration rate obtained from modeling is 0.026 cm/second and is used as the basis for a numerical approach using the Geostudio SEEP/W software. The results of the infiltration test which are simulated show that the higher pore water pressure in the soil underneath the groundwater table, the greater the volume of water absorbed by the soil. The addition of water pressure occurs along with the flow of water in the drainage channel. Water will seep in the porous concrete and soil, moving downhill following the direction of gravity. Once there is no flow in the drainage channel, the water will press in all directions to fill the gaps in the surrounding pores.
