Description
Direction and depths of hyporheic exchange fluxes at the groundwater ‐ surface water interface are drivers of biogeochemical processes influencing nutrient cycling and water quality. Model concepts on the dynamic relationship between hyporheic exchange fluxes and exchange depth are typically based on the assumption of a linear relationship between both measures. Here, we quantify seasonal and episodic variations of hyporheic exchange fluxes and hyporheic exchange depths with methods of heat tracing. Numerically (FLUX‐BOT) and analytically (VFLUX; method based on temperature amplitude dampening developed by Hatch et al., 2006, https://doi.org/10.1029/2005wr004787) working program scripts were used to solve the one‐dimensional conduction‐advection‐dispersion equation and compute hyporheic flux rates from three vertical sediment water temperature profiles recorded continuously in a …
