Dissolved material transport—the flushing effect in surface and subsurface flow

The study deals with the relationship between specific conductance and water flow in a small catchment. Three flow types were studied: (a) channel flow; (b) overland flow; (c) subsurface flow. The study of the three flow types demonstrates the important role of the flushing effect in small basins. The flushing effect is seen as an increase in water conductivity in the early stage of an event. Flushing is probably a function of accumulation in the basin. Accumulation is best defined as a function of time elapsing since the last heavy rain. The study has been carried out in the School of Geography at Leeds University, Leeds LS2 9JT, England.
