An elementary tool for Ecological Reserve monitoring in high-value conservation catchments in South Africa was developed.

To use a variety of data sources to compile a framework of change at temporal and spatial scales of relevance to river ecosystems, and to correlate these with known, and measured, changes in river ecosystem condition with the aim of identifying the long-term: (1) natural cycles; (2) non-flow related impacts and (3) flow related impacts on components of the rivers.

Quantifying the links between patterns of riparian vegetation and flow on South African rivers. Current knowledge, existing data from Reserve studies, and empirical evidence was synthesized to propose a naming convention, methods of identification and a description of the characteristics of lateral zonation patterns in riparian vegetation communities.

Development of Decision Support System (DSS) software to automate the process for Environmental Flow Assessments.  The software is different from current DSSs in the field in that it fully incorporates the ecological, social and socio-economic aspects of management options to the same level of detail and sensitivity as the economic and engineering aspects.  The DSS is based on advances made in the DRIFT methodology through its application in Southern and East Africa.

Project Leader and Editor:  Multi-authored book on the history of the management of Cape Town’s rivers, including options of future planning and management.

Researcher. Research Project aimed at: The development of predictive tools and indices to assess the impact (or risk of impact) of groundwater abstraction on the environment; improved understanding of groundwater dependent ecosystems (GDEs) in the Table Mountain Group (TMG), development of innovative techniques to determine the impacts of groundwater abstraction on the environment; development of indicators to monitor the effect of abstraction; and improved understanding of the impact of changing low flows on freshwater ecology and the relationship between surface flow, event discharge from high-lying TMG unconfined aquifers and deep confined-aquifers in maintaining wetlands or seeps.

Author: Detailed manual for the biophysical components of the DRIFT method, including user-guides to the DRIFT database and DRIFT Hydrological software.

Documentation and further development of the DRIFT method, a scenario-based methodology for Environmental Flow Assessments, which was developed for use in the Lesotho Highland Water Project.  DRIFT has subsequently been used in seven countries on numerous projects.
