Abstract: Flood is always occur in Makassar in almost every rain season without exception in 2013. Flood prevention requires effective drainage design with environmental concept, to accommodate and flow water from the road body to the water absorption media to the soil layer beneath. Laboratory research is required to find out: dimension, width ratio, material and pore holes depth that effective in absorbing water from drainage tunnel body to lower soil layer. The research was conducted with experimental study using pore drainage model. The test should be performed in two stages which are static and dynamic flow. The research is the initial test which was observed with 3 variations of hole diameter, 3 variations of soil textures and 3 variation of water surface height in the tunnel. From the observation and laboratory test, it is expected to gain ideal pore holes dimension according to soil condition of the drainage tunnel.
