Short Summary

This study examines the correlation between remote sensing indices and soil infiltration dynamics of treated wastewater in a restored wetland to optimize irrigation and monitor recycled water fate.

Objective

• To determine the relationship between measured soil moisture and remote sensing indices (GNDVI and NMDI) to evaluate the movement of treated wastewater through soil and plants in a restored wetland ecosystem.

Study Configuration

• Spatial Scale: Local site (Thomas Dairy restored wetland, Tigard, Oregon).
• Temporal Scale: Not specified.

Methodology and Data

• Models used: Comparative analysis of vegetation and moisture indices (GNDVI and NMDI).
• Data sources:
  • Field sensors (TEROS and ATMOS devices).
  • UAS (Unmanned Aircraft System) true color and multispectral imagery.
  • Sentinel-2 satellite imagery.

Main Results

• Remote sensing indices (GNDVI and NMDI) provide a viable geospatial tool for assessing soil moisture and plant health.
• The integration of UAS and satellite data allows for the monitoring of treated wastewater infiltration and the tailoring of irrigation practices to the specific needs of the native plant community.

Contributions

• Establishes a geospatial framework for monitoring the fate of recycled water in restored wetlands.
• Provides a tool for ensuring regulatory compliance regarding recycled water use.
• Offers a method to quantify the agronomic rate of native plant communities to optimize irrigation management.

Funding

• Not specified.
