Ressi experimental catchment: Ecohydrological research in the Italian pre‐Alps


Zuecco, Giulia; Marchina, Chiara; Gelmini, Ylenia; Amin, Anam; van Meerveld, H J; Penna, Daniele; Borga, Marco (2021). Ressi experimental catchment: Ecohydrological research in the Italian pre‐Alps. Hydrological Processes, 35(3):e14095.

Abstract

Ressi is a small (2.4 ha) forested catchment located in the Italian pre‐Alps. The site became an experimental catchment to investigate the water fluxes in the soil–plant–atmosphere continuum and the impact of vegetation on runoff generation in 2012. The elevation of the catchment ranges from 598 to 721 m a.s.l. and the climate is humid temperate. The bedrock consists of rhyolites and dacites; the soil is a Cambisol. The catchment is covered by a dense forest, dominated by beech, chestnut, maple, and hazel trees. The field set up includes measurements of the rainfall in an open area, streamflow at the outlet, soil moisture at various depths and locations, and depth to water table in six piezometers at a 5‐ or 10‐min interval. Samples of precipitation, stream water, shallow groundwater and soil water are collected monthly for tracer analysis (stable isotopes ($^{2}$H and $^{18}$O), electrical conductivity and major ions), and during selected rainfall–runoff events to determine the contribution of the various sources to runoff. Since 2017, soil and plant water samples have been collected to determine the sources of tree transpiration. Data collected in the period 2012–2016 are publicly available. Data collection is ongoing, and the data set is expected to be updated on an annual basis to include the most recent measurements.
