{"product_id":"9780784409930","title":"Standard Guideline for Fitting Saturated Hydraulic Conductivity Using Probability Density Function; Standard Guideline for Calculating the Effective Saturated Hydraulic Conductivity","description":"\u003cp\u003eTwo standards are combined that explain the critical factor of saturated hydraulic conductivity to effectively and accurately measure groundwater flow and transport of contaminants. All saturated hydraulic conductivity measurements are subject to variability—even in the most geologically homogeneous aquifers—caused by local fluctuations in an aquifer's textural characteristics. Averages of these fluctuations constitute a set of values that can be subsumed into a more general probabilistic description of the sample by means of a probability density function. Applying probabilistic procedures to the saturated hydraulic conductivity produces effective hydraulic conductivity, which can be used to estimate average specific discharge, average linear velocity, and other key variables in groundwater flow. \u003c\/p\u003e\u003cp\u003eANSI\/ASCE\/EWRI Standard 50-08(R2016) provides current guidelines for fitting saturated hydraulic conductivity using probability density functions.
