The exfiltrating groundwater was captured in in-stream reservoirs constructed in the ditch. We physically separated tube drain effluent from groundwater discharge before it entered a ditch in an agricultural field. We developed an experimental field set-up to study the dynamics in Fe(II) oxidation and mechanisms of P immobilization at the groundwater-surface water interface in an agricultural experimental catchment of a small lowland river. The mechanisms and rates of the iron oxidation process with associated binding of phosphate during exfiltration of anaerobic Fe(II) bearing groundwater are among the key unknowns in P retention processes in surface waters in delta areas where the shallow groundwater is typically pH-neutral to slightly acid, anoxic, iron-rich. The availability of P in surface waters is controlled strongly by biogeochemical nutrient cycling processes at the soil- water interface. Fluxes of non-point P sources to surface waters originate from surface runoff and flow from soil water and groundwater into surface water.

Use website settings to switch between units and 7 different languages at any time. These units are often used by sailors, kiters, surfers, windsurfers and paragliders. We use knots and degrees Celsius as our default units.
