Abstract:
Over the last 2 years we have pursued the investigation of control rules to govern abstraction and an 18 month salinity modelling investigation with Birmingham University. This work was aimed at developing the existing distributed model to model historic salinity changes and predict potential salinity changes resulting from alternative abstraction strategies. This contract ends in December 1992. The work has produced some improvements to the model, however difficulty has been experienced in being able to represent the historical fluctuations in chloride, notably the fact that Tioxide and Ciba Geigy are very close and have vastly different chloride levels. Various management scenarios, to include removal of industrial abstractors and abstraction under control rules are being examined and compared with history. Ideally, NRA would like to be in the position where a final report on alternative management options and there consequences is available before presenting a final case for management of abstraction. However, the indications point to using the control rules set out below, as our preferred management of the aquifer. We anticipate that when we have the salinity investigation final report the way forward will not significantly differ to that which is set out in the preferred control rule below.
