A laboratory column study was carried out to determine the clogging mechanisms prevailing when Ellen Brook water was to be used to recharge an unconfined aquifer north of Perth, employing recharge basins.

The laboratory study showed that clogging took place at the surface of the soil, and was caused by the suspended solids contained in the water filling in the interstitial spaces between the soil grains at the water soil interface, and thereafter acting as a filter. The reduction in infiltration rate as a function of time, following the theory of filtration, confirmed the experimental observation.
