This presentation will detail two new statistical tools for shallow hydrogeology, both of which will soon be freely available. The first tool is for time-series modelling of unconfined groundwater hydrographs. It allows the decomposition of a hydrograph to individual drivers, such as pumping and climate, under non-stationary climate conditions while also providing insights into observed […]

Calculations of groundwater inflows to streams, assuming that groundwater and surface runoff are the two major reservoirs, using environmental tracers (e.g., Cl or Rn) and physical techniques based on analysing stream hydrographs commonly yield different results. In general, geochemical techniques produce lower estimates of baseflow than physical techniques and, even within the suite of geochemical […]
