Technical notes : hyporheic zone sampling procedures

This report describes sampling apparatus that we produced as part of the Abandoned Mine Project, under the Groundwater Science programme. The report introduces the concepts of the overall study and identifies the need for sampling apparatus that can be installed within the riverbed. The report describes the development of three types of hyporheic zone sampling apparatus including:  Hyporheic zone multilevel sampler  Hyporheic zone DGT (diffusive gradients in thin films) disc sampler  Hyporheic zone DGT strip sampler The report explains the design, installation, monitoring and removal of the devices and discusses their successful implementation at a field site..
