This dataset contains monthly crop irrigation requirement (CIR) values from 1938 through 2014 for six canal service units used in the Lower Rio Grande Basin groundwater flow model (SSPA, 2007). CIR values from 1938 through 2010 were extracted from the New Mexico Office of the State Engineer’s (NMOSE’s) Canal spreadsheet, version 11.2 (Barroll, P., NMOSE, written commun., 2011). CIR values from 2011 through 2014 were copied from a year within the 1938 through 2010 dataset with a similar total annual precipitation as recorded at the State University, NM US station, part of the National Oceanic and Atmospheric Administration (NOAA) National Climatic Data Center (NCDC) Global Historical Climatology Network (GHCND) (NCDC, 2016a, b). CIR values are presented in units of acre-feet per acre.

This dataset contains annual Rio Grande Project surface-water allotments and diversion allocations from 1940 through 2014 to lands within New Mexico, Texas, and Mexico. Allotment and allocation values were extracted from the Allocation spreadsheet (Ferguson, I., Bureau of Reclamation, written commun., 2016). Allotment values are presented in units of acre-feet per acre. Allocation values are presented in units of acre-feet.

This line vector dataset represents tributary segments simulated with the Streamflow-Routing (SFR) Package for MODFLOW-One-Water Hydrologic Flow Model in the Rio Grande Transboundary Integrated Hydrologic Model (RGTIHM).

This dataset contains the model-simulated area of 57 water-balance subregions (WBS) in the Rio Grande Transboundary Integrated Hydrologic Model (RGTIHM) within the six canal service units used in the Lower Rio Grande Basin groundwater flow model (SSPA, 2007), as well as the fraction of the area of each WBS with irrigation-water supplied by a combination of groundwater and surface-water relative to the total area within the service unit containing the WBS with irrigation-water supplied by a combination of groundwater and surface-water. Area values are presented in units of acres.

This tabular dataset represents groundwater-level elevation measurements used as head and drawdown observations for the Rio Grande Transboundary Integrated Hydrologic Model (RGTIHM).

This point vector dataset represents tributary pour points used as model boundary inflow locations to the tributary Streamflow-Routing (SFR) Package network for recharge and runoff simulated by the Transboundary Rio Grande Watershed Model (TRGWM) for the Rio Grande transboundary integrated hydrologic model and water-availability analysis, New Mexico and Texas, United States, and Northern Chihuahua, Mexico (Hanson and others, 2018).

This point vector dataset represents the location of wells and contains construction information of wells used for groundwater head and head-difference observations for the Rio Grande transboundary integrated hydrologic model and water-availability analysis, New Mexico and Texas, United States, and Northern Chihuahua, Mexico.

This tabular dataset represents monthly flow at 61 surface-water points of diversion used to route flow in the Streamflow-Routing (SFR) Package for MODFLOW-One-Water Hydrologic Flow Model in the Rio Grande Transboundary Integrated Hydrologic Model (RGTIHM). Thirty-one of the 61 diversion points represent surface-water deliveries to combined groundwater and surface-water water balance subregions (WBS), and the remaining 30 diversion points represent diversions to canals and laterals along the surface-water conveyance network. Flow in this tabular dataset is specified monthly at each diversion point as either a rate (volume per time) in cubic feet per day, or as a fractional split from the simulated flow in the upstream segment. See the Div_ID attribute in the RGTIHM_SFR_Diversion_Pts and RGTIHM_SFR_Segments feature classes for the location of the points of diversion and the downstream segment to which the flow was routed, respectively.

This tabular dataset represents the source of monthly flow at 18 surface-water inflow points used as input into the Streamflow-Routing (SFR) Package for MODFLOW-One-Water Hydrologic Flow Model in the Rio Grande Transboundary Integrated Hydrologic Model (RGTIHM). Fourteen of the inflow points represent wastewater treatment plant (WWTP)/water reclamation plant outfalls, two of the inflow points represent electric plant outfalls, and the remaining two inflow points represent gaged Rio Grande below Caballo Reservoir and Bonita Lateral flows near the beginning of the SFR network within the RGTIHM. See the Inflow_ID attribute in the RGTIHM_SFR_Inflow_Pts and Inflw_ID attribute in the RGTIHM_SFR_Segments feature classes for the location of the points of inflow and the segment to which the flow was applied, respectively.

This point vector dataset represents 1,874 municipal and industrial well locations and attributes used as input data for the Rio Grande Transboundary Integrated Hydrologic Model (RGTIHM). Attributes include well construction information, historic water use information, and flags indicating assumptions made for modeling purposes. Data were compiled from various sources; see Supplemental Information for details.
