Thiem equation 1906

WebThe Thiem's equilibrium equation for steady flow in confined aquifer is used to determine piezometric head at any point at a radial distance r from the center of the well and is represented as Q sf = 2* pi * K * H *(h 2-h 1)/ ln (r 2 / r 1) or Steady Flow in a Confined Aquifer = 2* pi * Coefficient of Permeability * Width of aquifer *(Piezometric Head at Radial … Web18 May 2024 · Hydraulic conductivity values were obtained using Eq. (1) (Thiem, 1906), taking the saturated thickness to be equal to 329 m (the depth of the well minus the depth of the static level) and considering a radius of influence of 950 m once the quasi-steady …
