Michael has also served as an external examiner at the University of the Witwatersrand. What Michael enjoys most is being with his family as well as walking, cycling, gardening and spending time outdoors. Chris Brooker Pr Eng Member Chris is the owner of cba Specialist Engineers which was founded in 2001. He joins or assembles teams for specific river re-naturalisation, wetland rehabilitation and stormwater or flood management projects. Chris is an Honorary Senior Lecturer in the School of Civil and Environmental Engineering at the University of the Witwatersrand and holds a BSc and MSc in engineering from the university. Among the more recent environmental projects that Chris has been involved in are the rehabilitation of Bruma Lake and the re-naturalisation of streams in Paterson Park and the Killarney Golf Course. He has a special interest in stormwater modelling for catchment management and the mitigation of the negative im- pacts that urban development has on the ecology and morphology of the receiving rivers. In this field Chris has recently worked on the catchment management modelling for Modderfontein, assisted with the catchment management plan for the Jukskei River, and worked on the City of Johannesburg’s Stormwater Management Manual. Chris gets great pleasure from spending time in the bush where photography and bird watching compete with “just sitting”. Lansea Loubser Member Lansea completed her BSc in civil engineering from the University of Cape Town as well as her BEng (hons) in environmental engineering from the University of Pretoria. Lansea works as a civil engineer at Jones & Wagener Engineering and Environmental Consultants and has four years of experience in the design and surveillance of tailings storage facilities as well as experience in water quality and environmental monitoring. Lansea has been involved in the pre-feasibility, feasibility and detailed design stages of tailings storage facilities and has also done surveillance and design work on facilities in both South Africa and Ghana. Her area of expertise includes geotechnical engineering with an emphasis on the design and operation of tailings facilities. Her design skills range from geometric design of waste rock embankments, to access roads and ramps, stormwater management, emergency spillways, stream diversions, canals and stilling basins. She has also gained significant experience with detailed investigations of water quality. Johann le Roux Pr Tech Eng Member Johann le Roux is a professional engi- neering technologist with over 10 years’ experience in the management, design and implementation of a wide range of environmental engineering projects. Johann has general and specialised engineering skills in the field of envi- ronmental engineering which include the development of water balances, integrated waste management plans, concept and detail design of general and mine waste facili- ties, mine rehabilitation planning, closure, costing and construc- tion monitoring of large capital projects. He has also participated in all phases of project management for projects, which vary from specialised one-offs to turnkey and EPCM projects. As a director at MineLock Environmental Engineers, Johann thrives under pressure and approaches problem solving in a calm, logical and analytical manner. He has a strong work ethic and is actively involved in supporting his team to meet deadlines and client requirements.
