High‐frequency monitoring of hydrological and biogeochemical fluxes in forested catchments of southern Chile

Abstract: The variability of rainfall-dependent streamflow at catchment scale modulates many ecosystem processes in wet temperate forests. Runoff in small mountain catchments is characterized by a quick response to rainfall pulses which affects biogeochemical fluxes to all downstream systems. In wet-temperate climates, water erosion is the most important natural factor driving downstream soil and nutrient losses from upland ecosystems.Most hydrochemical studies have focused on water flux measurements at hourly scales, a… Show more

“…Increasing dissolved nitrogen load in river water and the degradation of water quality are closely related to anthropogenic activities and ecological conditions. About 63% of the global rivers no longer flow freely due to river damming, leading to retention and removal dynamics of the dissolved nitrogen in rivers. Heavy rainfall events disproportionately increase in the dissolved nitrogen species of river water, resulting in algal blooms and hypoxia within the estuaries. Meanwhile, increasing river runoff caused by heavy rainfall forces dams to regulate water levels to prevent flooding, further obscuring the cycling path of dissolved nitrogen in rivers . From another perspective, the accumulation of riverine dissolved nitrogen has potential ecological risks: dissolved organic nitrogen (DON) is a potential contributing factor of eutrophication in estuaries, and ammonia nitrogen in dissolved inorganic nitrogen (DIN) exhibits exposure toxicity to aquatic organisms and human beings .…”
