Delineation of water flow paths in a tropical intermittent stream system under changing land use: Isotopic and geochemical assessment

Abstract:

Intermittent streams strongly depend on hydro-climatological conditions. Interest in the ecology and hydrology of these streams has recently increased worldwide because they influence biological processes, determine water availability to humans, and are highly vulnerable to impacts of global drivers of change. However, most research on hydrological intermittence has been carried out on temperate environments, while knowledge of intermittent streams in tropical settings remains limited. To fill this knowledge gap, the Cube River Ecohydrological Observatory situated in Choco bioregion was established in late 2020 in the Pacific lowlands of Northwestern Ecuador. The CREO exhibits a variety of land uses ranging from tropical rain forest to highly deforested areas used for intensive agriculture and cattle grazing. Using a combined dataset of hydrological and tracer (isotopic and geochemical) observations …
