An assessment of possible factors contributing to well level fluctuations in holderness boulder clay, East Yorkshire

Abstract

It was found from an analysis of Holderness boulder clay well fluctuations that their responses were not in agreement with the normal mechanism associated with ground-water recharge i.e. a function of soil moisture content, depth to water table and pore size distribution of the material in the unsaturated zone. On the contrary there was an unusually short time lag between a water surplus producing rainfall and the initial well hydrograph response. Subsequent discussion tends to favour inseepage into the well from a perched water table located in the A soil horizon.
