Young Water Fractions in a Mediterranean Mountain Catchment Over 58 Months

58 months of oxygen-18 isotope data from soil, ground, and stream waters in the 0.56 km² Can Vila catchment. The dataset includes 1,529 determinations used to investigate young water fractions and their sensitivity to precipitation and sampling frequency. It was authored by Francesc Gallart and is available via Open Access.

Use Cases

• Modeling young water fraction (Fyw) dynamics based on water table and discharge variations described in the study.
• Assessing the impact of sampling frequency on water age estimations using the simulated virtual thorough sampling (F**yw) method.
• Comparing catchment water age metrics using flow-averaged (F*yw) and time-averaged young water fractions.
• Analyzing the relationship between precipitation forcing and young water fractions across different hydrological compartments.

Strengths

• Contains 1,529 oxygen-18 isotope determinations providing a substantial basis for analysis.
• Covers 58 months of sampling across multiple water sources (rain, soil mobile water, groundwater, stream water).
• Employs dynamic sampling strategies for stream water, adapting intervals from 30 minutes to 1 week based on flow.

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• Row count is unknown, which may limit suitability assessment.
• Last update date is unknown; freshness unverified.
