Small ponds in headwater catchments
WebSolute concentrations in headwater streams vary with discharge due to changing flow paths through the catchment during precipitation events. A comparison of stream chemistry across three headwater catchments reveals that solute heterogeneity across each landscape controls how different solutes respond to increasing discharge. WebNov 29, 2024 · The sampled lakes and ponds cover a range of sizes from below 1 ha in West River to the larger downstream West and East lakes ( ∼ 140–160 ha). 3 Methods 3.1 Field methods and hydrochemistry To explore downstream changes in DOM across regions, we used a transect approach in this study.
