It is important to measure the seepage flow behavior in the river levee caused by heavy rainfall and flood for estimating the safety factor of the river levee related to seepage. In this paper, the long term continuous field observations of soil water content and water level have been carried out in the back slope of the leaking river levee. Soil water contents at the different depths with in the soil profile were measured by using several intrusive soil moisture probes. Observed soil water contents with time were used to estimate the movement of two dimensional soil water content profiles of the back slope of the river levee. Changes in pore water pressure at the local scale in the river levee and the permeable base layer were measured by using several driven piezometers to confirm the existence of seepage flow line or water level. Through the observed variations in soil water contents and pore water pressure, the specific features of the seepage behavior in the leaking river levee are investigated.
