Abstract:
A conceptual model of the regional hydrogeology of the White Peak, considered fundamental to the understanding of the local (Wye) catchment has been presented. Specific to the local catchment, an investigation of the karst hydrogeology has been carried out in the context of its geological setting using results from: tracer experiments, chemical analyses of spring water, and hydrograph analyses; alongside detailed consideration of speleogenetic processes and terrain evaluation. Derived from these studies, a conceptual model has been developed, which represents the catchment hydrogeology in a number of hydrogeological units. Their attribution reflects the lithological differences and material responses to both stress and mineralization that have exerted significant influence on speleogenetic processes in the catchment. The units exhibit different recharge, through-flow and resurgence characteristics. Speleogenetic processes in some of the bedrock units support the inception horizon hypothesis. Flow paths typically pass through more than one hydrogeological unit. Lead-zinc-fluorite-baryte mineralization is associated with the dominant hydrogeological unit on the eastern side of the catchment. The mineral deposits were subject to several phases of exploitation facilitated by dewatering via drainage adits (soughs). Records pertaining to the soughs have been used to contribute to an understanding of the changes in groundwater levels as a consequence of mineral exploitation. A case study focused on Lathkill Dale has been used to test the catchment model and further explore human impacts on the hydrogeology. The major contribution of this work is in furthering the understanding of the hydrogeology and speleogenetic processes operating in the catchment. This is supplemented by additional contributions to the understanding of the distribution of superficial deposits within the catchment. Speculation regarding mineralizing processes; geomorphology; functioning of karst aquifers; seasonality of the groundwater chemistry; climate change, and the engineering properties of the bedrock may encourage further research in these areas.
