Harmonized Database of Western U.S. Water Rights (HarDWR)

In the arid and semi-arid Western U.S., access to water is regulated through a legal system of water rights. Individuals, companies, organizations, municipalities, and tribal entities have documents that declare their water rights. State water regulatory agencies collate and maintain these records, which can be used in legal disputes over access to water. While these records are publicly available data in all Western U.S. states, the data have not yet been readily available in digital form from all states. Furthermore, there are many differences in data format, terminology, and definitions between state water regulatory agencies. Here, we have collected water rights data from 11 Western U.S. state agencies, harmonized terminology and use definitions, formatted them for consistency, and tied them to a Western U.S.-wide shapefile of water administrative boundaries.

MERIT-Plus Dataset: Delineation of endorheic basins in 5 and 15 min upscaled river networks

The MERIT-Plus river network datasets in 5 and 15 arc minute resolution add value to the original upscaled IHU MERIT data with the main purpose of this work to identify the endorheic and exorheic basin types that are missing in the source datasets. Merging (cleanup) of small endorheic basins introduced few local changes in flow direction and basin identification data but made the datasets more suitable for a broader range of hydrological modeling applications that simulate water balance and accumulation in the endorheic lakes or land depressions.

A Gridded Price-Adjusted Quantity Index for Total Production of Crops for Irrigated and Rainfed Farms for the Contiguous U.S.

A price-adjusted quantity index is introduced for the total production of crops for irrigated and rainfed farms for the Contiguous U.S. (without crop details) at 5 arc-min resolution. Here, the production of all crops in each grid cell is aggregated into two crop composites: irrigated (QCROP_irr) and rainfed (QCROP_rfd). Each composite may have a slightly different mix of crops with different prices. To consider price differences, a “corn-equivalent” index is generated for production. The dataset also represents the cropland area for irrigated (QLAND_irr) and rainfed (QLAND_rfd) around the year 2010 provided in NetCDF, GeoTIFF, CSV, and HAR file formats.

A Gridded Dataset for Groundwater Sustainability Restriction Policy Scenarios for the Contiguous U.S.

Three scenarios of “low”, “medium”, and “high” levels of restriction on groundwater are developed. This dataset includes likely groundwater sustainability restriction policies (GSPs) considering 2010 levels of groundwater withdrawals in the United States. Groundwater sustainability is defined in a rather simplified way assuming the groundwater extraction should not exceed the average recharge rates. The data is provided in NetCDF, GeoTIFF, CSV, and HAR file formats.

GAEZ+ 2015 Monthly Cropland Data

An update to global gridded monthly crop datasets. This new dataset uses the crop categories established by the Global Agro-Ecological Zones (GAEZ) Version 3 model, which is based on the Food and Agricultural Organization of the United Nations (FAO) crop production data. We used publicly available data from the GAEZ+_2015 Annual global gridded dataset (Frolking et al., 2000) along with data from the MIRCA2000 dataset (Portmann et al. 2008) on crop rotations, cropping intensity, and planting and harvest dates to generate c.2015 monthly crop physical area by crop production system (irrigated and rainfed) for 26 crops and crop categories globally at 5-minute resolution. Each crop category can have up to 5 subcrop categories to represent crop rotations, resulting in a total of 93 individual crop/subcrop/production system combinations (93 files total). These data are in standard georeferenced gridded format (netCDF files), and can be used by any global hydrology, land surface, or other earth system model that requires gridded annual or monthly crop data inputs.

Hydrologically Consistent Dams Database

To accurately represent the routing and storage of water through terrestrial river networks, macro-scale hydrologic models require accurate representations of impounded water-bodies throughout the model domain. The Hydrologically-Consistent Dams (HydroConDams) dataset provides a critical compilation and correction of available datasets for the Conterminous United States (CONUS). HydroConDams provides locations for the single major point of outflow of reservoirs, maximum capacity information, inundated surface area, upstream catchment area, dam construction year, and primary dam purpose. These data are considered appropriate for representing the routing and storage effects of impounded waterbodies along river networks for meso- to macro-scale models of terrestrial hydrology and the land-surface (pixel-sizes from 100’s m to 100’s km).

Model code for: Quantifying the Impacts of Compound Extremes on Agriculture and Irrigation Water Demand

This Stata code estimates a model to investigate the impacts of compound extremes, water stress, and heat stress on crop yields. It requires "soilMoistureData.dta", which can be found in the data product cited above, Haqiqi et al 2020 (DOI:10.4231/0M14-EY38). The code will estimate 1) the marginal impacts of heat stress on crop yields; 2) the marginal impact of daily soil moisture extremes on crop yields, and 3) the conditional marginal impact of heat and soil moisture on crop yields. This code can be used for studying the impacts of compound extremes on agriculture. The code generates figures and tables too.

FLOPIT (FLOod Probability Interpolation Tool)

Code for interpolating inundation return periods for parcels of land between the 10 year and 500 year FEMA flood water surface elevations. The code's goal is to improve flood risk communication and understanding by interpolating flood probabilities from existing FEMA flood maps and data. This analysis focuses on two locations: a model testing case in the Sims Bayou, Houston, TX. and an application case at the town of Muncy, PA.

SIMPLE-G model

SIMPLE-on-a-Grid (SIMPLE-G) is a multi-region, partial equilibrium model of gridded cropland use, crop production, consumption and trade. It is an extension of the SIMPLE model that has been applied to study long run sustainability issues in the global food-water-environment nexus. Rather than looking at regions or country aggregates, SIMPLE-G divides the world into georeferenced grid-cell units. This allows SIMPLE-G to explicitly incorporate local environmental constraints in its projections, account for sub-national heterogeneity of global drivers such as climate change and water scarcity, and assess local land and water use given future trends the global farm and food system. In SIMPLE, the world is split into sixteen economic regions. Regional consumption is disaggregated into four commodities (crops, livestock, processed foods and biofuels). Regional demand is driven by population, per capita income, and biofuel mandates (all exogenous in the model) as well as prices (endogenous to the model). SIMPLE-G extends the existing SIMPLE model by disaggregating rainfed and irrigated production and modeling these processes at the individual grid-cell level. Regional crop output is obtained by aggregating across the grid cells (30 arc-min resolution) within each region. Crop production follows a nested constant elasticity of substitution (CES) function. Water is an explicit input used by the irrigated sector only. Water consumption is computed as the product of gridded irrigated cropland area and a grid cell-specific consumptive water use parameter in m3/ha. By aggregating water use across grid cells within a sub-basin (defined below), we obtain total irrigation consumption. Water availability at each grid cell is exogenous in SIMPLE-on-a-Grid, and is obtained from the hydrological model.
