Abstract

Streambed vertical hydraulic conductivity (Kv) plays an important role in understanding the water exchange and contaminant transport system between river streams and groundwater flows. The tests were conducted at 464 test points of 10 test sites to measure the vertical hydraulic conductivity (Kv) for the streambed by using the falling-head standpipe permeameter. The traditional statistics and geostatistics methods were applied to determine the spatial variability of hydraulic conductivity. The Kv values range from 0.01 to 61.32 m/d with the mean value of 4.62 m/d, the thermal method shows higher discharge rates about in 48cm~51cm depth. In the winter test groundwater recharge was more frequently than in the summer test. The Kv values of streambed sediment decreases with increasing depth, different sediment particle size is mainly influence factors. At the same test site, the difference in flux can be explained by different characters of sediment.
