18-Year Watershed Experiment Data on Large Wood Restoration and Geomorphic Response

An 18-year Intensively Monitored Watershed experiment tested low-tech, process-based wood additions in three tributaries to Asotin Creek, Washington. The dataset, authored by Stephen N. Bennett and last updated in 2026, includes results from installing 654 large wood structures and monitoring their effects on wood frequency, jam formation, and channel morphology. Adaptive management actions, maintenance, and responses to fire and high flows are documented.

Use Cases

• Modeling geomorphic unit changes based on reported increases in bar and pool area.
• Analyzing wood transport and storage dynamics based on reported structure movement and wood accumulation.
• Evaluating the effectiveness of adaptive management strategies based on described adjustments like building beaver dam analogs and felling key pieces.
• Assessing floodplain connectivity based on reported increases in perennial side-channels.

Strengths

• 18-year longitudinal study providing long-term ecological and geomorphic data.
• Detailed quantitative results including specific percentage changes in wood frequency, jam formation, and geomorphic unit areas.
• Describes a clear adaptive management framework with specific interventions like building 25 beaver dam analogs.

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• Row count is unknown, which may limit suitability assessment.
• The 6.4 MB file size suggests a relatively small dataset.
