Abstract:
Accurate water management decisions and policies are vital to ensuring the reversal of groundwater depletion and saltwater intrusion in the aquifers underlying the coastal plain of Maryland, Virginia, and North Carolina. Current methods offer data for the area on a limited, inconsistent basis, leading to an incomplete assessment of coastal aquifer conditions. By analyzing the area using remotely sensed data, water consumption behavior can be understood on a larger scale, contributing to better-informed water management policies. Regional analysis of evapotranspiration using Landsat 8 has been shown to be a useful tool in understanding water consumption behavior. These data, combined with groundwater storage information acquired using Gravity Recovery and Climate Experiment (GRACE) data, can help establish a water budget for the area, allowing for better-informed water management decisions. Establishing a means to calculate evapotranspiration in the area using the Mapping EvapoTranspiration at High Resolution and Internalized Calibration (METRIC) model is a useful, accessible tool for water resource monitoring for both state agencies and Digital Harvest, a precision agriculture company using Unmanned Aerial Vehicle (UAV) collected data to analyze crops. METRIC outputs will enhance all parties’ understandings of water usage and stress in the vegetated areas studied. Furthermore, calculating groundwater storage trends over the past decade will better inform water resource policy for state agencies. Utilizing remote sensing data in the area will contribute to a large-scale, more complete understanding of the water consumption behavior in the area.
