Abstract
The Mississippi River Valley Alluvial Aquifer (MRVA) has been the primary source of irrigation water in Northeastern Arkansas since the early 1900s. Over time the MRVA water level has declined due to over-pumping of farm wells and water restrictive geology. The aquifer is expected to continue declining but with water conservation strategies in place, this vital resource could be preserved for future farmers. This thesis investigated using remotely sensed data to assess landforms associated with agricultural water conservation across Northeastern Arkansas. The remotely sensed data proved to be useful at creating temporal assessments of pre-existing irrigation reservoirs, identifying new irrigation reservoirs, and identifying precision graded fields. Using known spatial characteristics of irrigation reservoirs and precision graded fields, autonomous models were created through ArcGIS Pro ModelBuilder to assess the irrigation landforms regionally. The models were demonstrated to be accurate and can provide regular inventories of agricultural water resources across the region.
