Short Summary

This study presents a continental-scale statistical characterization of high-flow volumes at the outlets of 2,115 subbasins across the conterminous United States to support managed aquifer recharge planning. The results indicate that high-flow availability is highest in wetter regions and lowest in arid and semiarid areas.

Objective

• Investigate the spatial distribution of high-flow volumes (HFV) suitable for Flood-MAR planning at ungaged locations across the conterminous United States

Study Configuration

• Spatial Scale: Continental-scale, covering 2,115 subbasins across the conterminous United States
• Temporal Scale: Daily streamflow time series over a period of record (not specified)

Methodology and Data

• Models used: Four prediction in ungaged basins (PUB) methods: [list not provided]
• Data sources: Stream gage data from 701 locations, satellite and observation data for validation

Main Results

• Estimated daily streamflow time series using PUB methods with varying degrees of accuracy
• HFV quantiles estimated as weighted averages of PUB methods, along with associated uncertainties
• Spatial distribution of HFV availability and uncertainty across the conterminous United States

Contributions

• Provides a consistent, continental-scale foundation for Flood-MAR siting and screening
• Offers insights into the relationship between regional hydrology and managed aquifer recharge potential
