- Description:
- A procedure for estimating potential changes in the hydraulic conductivity of a silt layer in a canal was developed following McNeal's method for predicting the hydraulic conductivity of soils in the presence of mixed-salt solutions. The reason for using this method was to analyze the effect on seepage from the canal. A series of experiments on soil columns was conducted in order to determine the surface sealing effect by fine sediments and metabolic products of micro-organisms activity. Similar tests were conducted using sterile soil and water. A comparison of predicted and measured conductivities was made. Physical dispersion is perhaps the primary factor in causing changes in seepage rate with time. For the case studied, the reduction in conductivity that could be attributed to soil-water chemical reaction is minor in magnitude as is also the effect of microbial action. Silting effect due to settlement of soil particles carried in canal water appears to have only a minor effect on conductivity change also.
