Short Summary

This study applies an integrated, data-driven framework to analyze hydroclimatic shifts in the Navasota River Watershed, revealing an accelerating wetting tendency and a statistically significant increase in annual peak streamflow, indicating heightened flood risk.

Objective

• To explore emerging hydroclimatic shifts in the Navasota River Watershed of east-central Texas by analyzing long-term precipitation and streamflow records in conjunction with reservoir operations.

Study Configuration

• Spatial Scale: Navasota River Watershed, east-central Texas.
• Temporal Scale: Over 100 years of precipitation and streamflow records; post-1978 reservoir operations.

Methodology and Data

• Models used: Autocorrelation analysis, Mann–Kendall trend test, modified Mann–Kendall trend test, Pettitt’s change-point detection.
• Data sources: Historical precipitation records, historical streamflow records, reservoir operations data.

Main Results

• An accelerating wetting tendency was observed, particularly in decadal rolling averages and early-summer precipitation.
• A statistically significant increase in 10-year moving averages of annual peak streamflow was detected.
• Abrupt hydroclimatic regime shifts were not identified.
• Subtle but persistent changes indicate evolving watershed memory and increased flood risk in the post-dam era.

Contributions

• Reframes rainfall and streamflow trend analysis as a dynamic tool for anticipating hydrologic regime shifts.
• Highlights the urgent need for adaptive water infrastructure and flood management strategies in rapidly urbanizing and climate-sensitive watersheds.
• Provides an integrated, data-driven framework for analyzing complex hydroclimatic shifts influenced by climate, land-use, and human infrastructure.
