WebThe resulting cumulative particle size distributions were used to estimate saturated hydraulic conductivity using empirical methods available in the hydrology and soil science literature [32,33]. Two of the most commonly used are the Hazen and Kozeny–Carman equations [10,34,35], which have the general form: Webpiezometers. The Thiem equation [e.g., Fetter, 1995] provides an estimate of the transmissivity T through measurement of the pumping rate Q and the steady state hydraulic head h (r) at two piezometers which are at distances r• and r 2 from the pump- ing well. The Thiem equation, when applied for r• < r 2 < R,
