Hydraulic conductivity is a \nmeasure of how much water flows through a unit section of an aquifer, under a unit gradient in \na specified amount of time.  Specific yield is a measure of how much water will drain from the \naquifer by gravity. Both of these properties are important to develop a hydrogeologic framework \nfor an aquifer and to gain an understanding of how water flows through the aquifer.\n\t\t\nIncluded in this metadata document are the attribute definitions of all tables related to the feature \nclass pts_K_Sy_TWA, including tbl_K_Sy_RawDataMaster a table of well point lithology records \nthat terminate at the base of the aquifer. This document also includes the attribute definitions of \nthe table of subsurface material, called tbl_Material that contains texture, grain-size, and sorting \nproperties of the aquifer material, and the attribute definitions of the table of multipliers called \ntbl_Multiplier, which, based on certain subsurface materials, would reduce the computed values \nof these properties. The two tables, tbl_Material and tbl_Multiplier are used in the Geoparm \nmacro to compute the K and Sy values at the wells in the pts_K_Sy_TWA feature class.  \nAttribute definitions for tbl_K_Sy are also included in this metadata document; tbl_K_Sy is the \noutput table created by the Geoparm macro.  The thickness weighted averages of K and Sy are \ncomputed by queries in this table after the macro is run. The thickness weighted averages were \nthen transferred to the point feature class.
