Freshwater specialist and advisor: A Feasibility Study and Pilot Project into the viability of the TMG Aquifer for bulk water supply to Cape Town, more particularly the deep confined portions of the Peninsula Formation.  Duties included evaluation of proposed well-field sites, design of a monitoring programme to assess future possible impacts of abstraction from the TMG aquifer on rivers and wetlands in the area and review of the subsequent monitoring activities, which have been outsourced.  This project is likely to continue into the future, to encompass establishment of pilot well-field and adaptive management of large-scale water abstraction for supply to Cape Town.

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.

EF Team Leader and Advisor:  An assessment of the relationship between the current flow regime in the river and the EFR recommended by the Desktop Model was examined, and appropriate changes be made to the recommended flows.  The results of these analyses were incorporated into the systems modelling for planning purposes.  Thereafter a ToR for a Comprehensive (reactive) EF assessment for the Orange River and its estuary was compiled.

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.

IFR Process Co-ordinator, Habitat Integrity Specialist and Group Leader: Determination of the Instream Flow Requirements of the Senqu, Matsoku and Malibamatso and Senqunyane Rivers, as part of the Feasibility studies for all four phases of the proposed Lesotho Highlands Water Project: Co-leader of all pre-project activities including project design, production of the project proposal and negotiations with the client.  Responsibilities include: co-ordination of an IFR Team of international scientists, co-ordination of all IFR activities, Habitat Integrity Assessment of the Senqu, Matsoku and Malibamatso and Senqunyane Rivers within the study area, report writing and compilation of all major reports.  This project led to the development of DRIFT and several other major projects with LHDA. Joint Venture with SMEC International.
