TLDR
In this article, a portion of the Gambier plain underlain by an unconfined aquifer with readily definable hydrologic boundaries has been divided into a number of areas within which soil types have similar hydrological properties, and mean annual recharge has been estimated for each area using both the tritium concentration and the chloride concentration of water within the soil profile.Abstract:
A portion of the Gambier Plain underlain by an unconfined aquifer with readily definable hydrologic boundaries has been divided into a number of areas within which soil types have similar hydrologic properties. Mean annual recharge has been estimated for each area using both the tritium concentration and the chloride concentration of water within the soil profile. Good agreement was obtained between the two methods with local recharge varying between 50 and 250 mm year-1. Total mean annual recharge for the area has been estimated to be 2.4 ± 0.3 x 108 m3 year-1, and this compares favourably with an estimated discharge of 2.5 ± 0.3 x 108 m3 year-1.read more

Chloride balance of some farmed and forested catchments in southwestern Australia
A. J. Peck,D. H. Hurle +1 more
TL;DR: In this paper, the authors estimate that removal of forest vegetation from forested catchments has increased groundwater discharge of whole catchments by amounts ranging from about 1 to 13 cm3/cm2yr, and the characteristic times for equilibrium of chloride input and loss on farmed catchments are estimated to range from 30 to 400 years.
