  • Title: Travel time to a well pumping an unconfined aquifer without recharge.
    Author: Chapuis RP, Chesnaux R.
    Journal: Ground Water; 2006; 44(4):600-3. PubMed ID: 16857038.
    Abstract:
    A solution is given for the travel time to a well pumping an ideal, horizontal unconfined aquifer, under steady-state conditions, when recharge from infiltration is negligible. Three forms of the solution are provided: a closed-form solution, an integral to be calculated in a worksheet, and a simple equation. The three forms of the solution give travel times nearly identical to those obtained using a finite-element code for saturated and unsaturated flow and particle tracking.
