ABSTRACT:

This dataset contains event-level hydroclimatic and hydrological variables for 209 rainfall–runoff events observed in four forest headwater catchments spanning contrasting ecoregions: Fuirosos and Font del Regàs in northeastern Spain, Upper Rappbode in Germany, and Krycklan C2 in Sweden. Each row represents one event and includes precipitation characteristics, antecedent hydroclimatic conditions, stream-discharge responses, riparian groundwater-table responses, runoff coefficients, and metrics describing the slope and hysteresis of the riparian groundwater–stream discharge relationship. The variables were derived from sub-daily monitoring records and were used in the statistical analyses and figures of the associated manuscript, “Contrasting drivers of riparian–stream hydrological dynamics during rainfall events across forest headwater ecoregions.” The accompanying README provides variable definitions, units, catchment codes, calculation details, and interpretation guidance. The dataset supports comparative analyses of rainfall–runoff generation, riparian–stream hydrological connectivity, and their variation across semiarid Mediterranean, subhumid Mediterranean, temperate, and boreal forest headwaters.

ABSTRACT:

This dataset presents daily values of stream discharge, stream dissolved organic carbon (DOC) and nitrate (N-NO3-) concentrations, riparian groundwater tables, and riparian soil water DOC and N-NO3- concentrations at three catchments (Rappbode - 2.58 km2, Font del Regàs - 13.0 km2, and Fuirosos - 9.94 km2) for different periods within 2013 to 2023.

ABSTRACT:

This dataset presents daily time series of dissolved organic carbon (DOC) and nitrate (NO3-) concentrations at three locations along the Font del Regàs stream for the period September 2010 to August 2012. The sub-humid, Mediterranean Font del Regàs catchment is located in northeastern Spain (total drainage area = 15.5 km2).

ABSTRACT:

This dataset presents 10-min resolution time series of stream water (Sw) and near-stream groundwater (Gw) levels for the period September 2018 to March 2020 at two Mediterranean catchments located in northeastern Spain: the sub-humid Font del Regàs (total drainage area = 15.5 km2, drainage area of the measurement location = 14.2 km2), and the semi-arid Fuirosos (total drainage area = 16.5 km2, drainage area of the measurement location = 9.9 km2).

ABSTRACT:

This dataset presents daily precipitation, temperature, stream flow, and riparian groundwater table time series for the period September 2010 to August 2012 at the sub-humid, Mediterranean Font del Regàs catchment, located in northeastern Spain (total drainage area = 15.5 km2). The dataset also includes biweekly measurements of groundwater tables at seven extra locations within a confined riparian area, and chemical data characterizing a riparian soil profile.
