Determining groundwater-surface water exchange from temperature-time series: Combining a local polynomial method with a maximum likelihood estimator Vrije Universiteit Brussel Universiteit Antwerpen Universiteit Gent
The use of temperature-time series measured in streambed sediments as input to coupled water flow and heat transport models has become standard when quantifying vertical groundwater-surface water exchange fluxes. We develop a novel methodology, called LPML, to estimate the parameters for 1-D water flow and heat transport by combining a local polynomial (LP) signal processing technique with a maximum likelihood (ML) estimator. The LP method is ...
