Slovakian River Flow Data for Multi-Season Drought Persistence Analysis

Supplementary file 2 from a study by Igor Leščešen provides data for analyzing hydrological drought persistence in Slovakia. The dataset is based on daily discharge records from 17 gauging stations in Carpathian headwaters and lowland reaches, aggregated into winter and summer seasons. It was last updated on 2026-05-22 and is licensed under CC-BY-4.0.

Use Cases

• Modeling drought persistence probabilities based on seasonal dry/wet state transitions.
• Simulating long-term drought spell lengths using Markov-chain methods.
• Assessing regional drought risk over 5- and 10-year horizons based on river flow anomalies.
• Comparing drought characteristics between alpine headwater and lowland river basins.

Strengths

• Includes data from 17 gauging stations with long near-natural discharge records.
• Analysis covers distinct physiographic regions from Carpathian headwaters to lowland reaches.
• Methodology is detailed, including Markov-chain fitting and generation of long synthetic series for 100-year event estimation.

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• The dataset is a 71.6 KB PDF, which is a very small supplementary file; the underlying raw data may not be directly included.
• Row count is unknown, which may limit suitability assessment.
