COMPUTATION SHEET <br /> PROJECT TITLE: Corral Hollow Sanitary Landfill PROJECT NO. 0939-003.16 <br /> DESCRIPTION: Average Groundwater Flow Velocity SHEET 3 OF 3 <br /> PREP. BY: M Capps DATE: 3/23/93 CHKD BY: DATE: `0W53 <br /> Groundwater flow SB-1 and MW-4 is toward the northwest. Bidirectional flow has been <br /> observed during previous quarters, with southeastward flow between SB-1 and MW-4. <br /> IDarcy's Law was used to calculate the groundwater flow velocity <br /> V = Ki/n <br /> Where: V = Average linear velocity <br /> K = Hydraulic conductivity <br /> i = Hydraulic gradient <br /> n = Porosity <br /> The values used to solve the equation are as follows: <br /> * K = 0.00008 Centimeters per second <br /> i = difference in elevation between wells/ horizontal distance between wells <br /> ** n = 0.3 <br /> * K value based on slug test conducted in MW-4 <br /> ** n value based on published porosity values <br /> The groundwater flow velocity was calculated between water levels in SB-1 and MW-4 as follows: <br /> water levels: 234.37 <br /> 234.21 <br /> Difference in elevation <br /> between wells: 0.16 <br /> Horizontal distance between well: 540 <br /> i = 0.0003 <br /> V = 8E-08 centimeters per second <br /> V = 0.08 feet per year <br /> for northwest flow between SB-1 and MW-4 <br /> h:velocity.xls <br />
