Aquaculture and Irrigation Water Use Model (AIWUM) 2.0 input and output datasets

Published by U.S. Geological Survey | Department of the Interior | Metadata Last Checked: January 27, 2026 | Last Modified: 2024-01-23T00:00:00Z
The Aquaculture and Irrigation Water Use Model (AIWUM) 2.0 employs remote sensing data sets and Distributed Random Forests (DRF), an ensemble machine learning algorithm, to predict annual groundwater use associated with irrigation and aquaculture from 2014 to 2020 in the Mississippi Alluvial Plain (MAP) and Mississippi embayment regions at 1-kilometer and 100-meter resolution (Majumdar and others, 2023). The response variable for the model are groundwater withdrawal rates from flowmeters in the Mississippi delta region associated with the Delta Voluntary Metering Program (DVMP). Explanatory variables include a variety of climate, remote sensing, and GIS data. Annual predictions of groundwater use from the DRF are disaggregated to monthly groundwater use using crop-specific groundwater withdrawal data from existing flowmeters across the MAP. This data release provides input and output datasets associated with AIWUM 2.0. Processing steps for attributing explanatory variables to groundwater withdrawal rates at flow-meters are available in metadata for the Inputs found in this data release and at the companion software release (https://code.usgs.gov/map/wu/aiwum-2.0-hydromap_ml-mirror).
