The Two-Streams catchment located in the KwaZulu-Natal Midlands, South Africa has been used as an experimental catchment over the past decade to investigate the impacts of Acacia mearnsii stands on hydrological processes. As part of the ongoing study, the hydrogeology of the catchment was investigated and characterized to understand the impacts of Acacia Mearnsii plantations on groundwater. The hydrological, hydrogeological, hydrochemical and environmental isotope methods were employed in characterizing the hydrogeology of the catchment.

The main purpose of this paper is to present a case study where soil moisture and rainfall data were evaluated for engineered tree plantations, to understand the potential impact on vertical groundwater recharge. Soil moisture for probes within the tree plantation root zones and reference sites within the same soil types were evaluated, in context to site rainfall patterns. Water transfer from shallow to deeper soil zones for a dataset of 2 years are presented.
