Abstract: A general method is presented for predicting the subsurface lateral inflow hydrograph from large unconfined aquifers into adjacent streams. It is based on grouping the pertinent variables into dimensionless parameters. The relationships between these parameters were obtained experimentally. Use was made of the analogy between the flow of water through a saturated porous medium and the flow of a viscous fluid in a Hele-Shaw model. The experimental results verified the applicability of the proposed method. Field problems with similar boundary conditions may be solved through the use of simple transformation equations. A comparison is presented between the experimental results and some of the approximate solutions available in the literature.
