Simulation of leakage inspection of dams based on flow field method

With the rapid development of water conservancy and hydropower in our country, the construction of dykes has also developed rapidly. However, since some DAMS have been built for a long time and have been damaged by river water immersion, rain corrosion, natural weathering, and other special hydrological environments for long time, dam leakage or dam break will always occur in every flood season. The flow field method is to detect the flow direction of water according to the distribution of current field potential. Emission electrodes are placed on both sides of the DAMS. Due to the existence of leakage, the resistivity of the leakage site is lower than that of the non-leakage site, and the leakage site will become the main channel through which the current flows. The simulation results of LABVIEW demonstrate the feasibility of the flow field method in dam leakage.
