Drainage and groundwater pumping works (Richard George and Kevin Jones) Notes prepared by Richard George and Rosemary Nott (APPENDIX 2) KEY OUTCOMES: • Emphasis on drains and flood management in the Belka Valley • Effectiveness was shown by photos and points of discussion (Dept of Agriculture monitoring was less able to show the full effects, but the photos showed where seepage from a sandplain had been intercepted by downslope drains. Kevin Jones noted areas at risk were still developing up-valley.) • The Belka example highlights the issues of design. Drains with major floodways installed would have their life expectation greatly increased. MERREDIN “Townsite Salinity” Notes prepared by Richard George and Jay Matta (APPENDIX 3)
