WebUse the Bouwer and Rice partially penetrating well equation to determine the radius through which the change in hydraulic head is dissipated during the slug test (Re). First solve for the ln(Re/R) then solve purely for Re. Hint: Solve for Re by using Equation 2. Note how you move the natural log term over to the other side of the equation. http://www.pointstar.com/Aquifer/SuperSlug.aspx
