SUSTAINABLE RIVER STABILIZATION
I value finding solutions for degraded, transformed and unstable rivers, using a minimum of hard engineered interventions and maximizing the use of natural vegetation where possible. My solutions are based on sound engineering principles while at the same time creating areas where natural river processes may be restored.
As many projects I work on are in rural areas, I value planning projects in such a way as to create employment opportunities for those so in need of support and a future.

· Planning of river rehabilitation projects (erosion control and sediment management with engineered structures such as weirs and groynes, as well as re-introduction of displaced indigenous river plant species)
· Drawing up tender documents, managing tender process, and supervision of construction of river stabilization projects.
· Provision of specialist hydrologist service (peak storm run-off determination, flood hydraulics modeling using HECRAS 1D and 2D.
· Planning of minor dam spillways, road culverts, and low level river crossings.
· Planning of general sustainable resource management projects such as minor erosion control structures, surface drainage (including road drainage), and subsurface drainage, in agricultural environments.
· Production and presentation of engineer training programs, as well as offering a mentorship service.
· Project monitoring using drone fixed point imagery
Western Cape Department of Agriculture (1989- 2019) : Soil Conservation Engineer
· Planned river rehabilitation projects (erosion control and sediment management with engineered structures such as weirs and groynes, as well as re-introduction of displaced indigenous river plant species)
· Developed the use of groyne structures for river bank erosion control as a more environmentally acceptable alternative to longitudinal retaining walls
· Assisted with the drafting of the National Soil Conservation Structure Design Manuals
· Established improved norms for the design of sub-surface drainage of agricultural land in the Western Cape (sub-surface pipe networks)
· Established improved norms for the design of surface drainage of agricultural land in the Western Cape (contour banks and concrete lined waterways)
· Supervised technical standard of engineering design for soil conservation structures done by LandCare officials (erosion control weirs, stock watering systems, sub-surface drainage, surface drainage)
· Presented soil conservation structure training courses to LandCare officials
· Managed the payment of subsidies to farmers for soil conservation works under the Soil Conservation Act (Act 80 of 1980)
Clifford Harris Pty Ltd (1984-1989) : Civil Engineer
· Designed concrete formwork, temporary reinforced concrete as well as temporary steel structures for the construction site (Palmiet Pumped Storage Scheme)
· Re-detailed concrete reinforcement to suit contractor’s construction program (Palmiet Pumped Storage Scheme).
· Produced contractor’s method statements for all work areas including tunneling, blasting, concrete works and structural steelwork (Palmiet Pumped Storage Scheme).
· Assisted with setting up claims for extra work at end of project (Palmiet Pumped Storage Scheme).
