Central Valley Hydrologic Model version 2 (CVHM2): Drain Flow Observations The original Central Valley Hydrologic Model (CVHM) did not simulate tile drain discharge in the west side of the San Joaquin Valley. The updated Central Valley Hydrologic Model (CVHM2) does simulate on-farm drains. The data for the drain flow and locations were obtained from the Berkeley National Laboratory is from (WESTSIM2) (N. Quinn, Berkeley National Laboratory, written communication., 2010). This component of the data release includes:e (1) three datasets included are a spreadsheet of the available observations with the drain flows in acre-ft/month, (2) a shapefile of the WESTSIM2 drain cells, and (3) a shapefile of the original WESTSIM2 drain cells translated to the CVHM2 model grid.

Four principle classes of geologic units can be distinguished: (1) material of three rugged arcuate mountain ranges circumferential to the imbrium basin; (2) terra materials superposed on these ranges; (3) mare materials; and (4) crater materials. Tags: Cassini, Geologic Map, Moon, geoscientificInformation Interferometric Synthetic Aperture Radar Data Used as Subsidence Observations for Model Calibration, Central Valley, California The Central Valley, and particularly the San Joaquin Valley, has a long history of land subsidence caused by groundwater development. The extensive withdrawal of groundwater from the unconsolidated deposits of the San Joaquin Valley lowered groundwater levels and caused widespread land subsidence—reaching 9 meters by 1981. More than half of the thickness of the aquifer system is composed of fine-grained sediments, including clays, silts, and sandy or silty clays that are susceptible to compaction. In an effort to aid water managers in understanding how water moves through the aquifer system, predicting water-supply scenarios, and addressing issues related to water competition, the United States Geological Survey...

Here we present downloadable flight line data from those surveys in comma-separated values (csv format). Three areas were flown along a draped surface with a nominal survey height above ground of 120 meters. The flight line spacing for these areas was 200 to 400 m for Area 123, in southwestern Oklahoma; 1000 m for Area 4, in northwestern Oklahoma, and 800 m for Area 5, in north-central Oklahoma. For each area control lines were flown at ten times the traverse line spacing. The surveys were flown to map subsurface geologic variations including ancient magmatic bodies, faults, and other geologic...

Each country/state/territory extent consists of four nested sampling grids at 50x50km, 10x10km, 5x5km, and 1x1km resolutions. The original 10x10km continental United States grid was developed by the Forest Service, U.S. Department of Agriculture for use in the interagency “Bat Grid” monitoring program in the Pacific Northwest and was expanded across Canada, the United States, and Mexico for the North American Bat Monitoring Program (NABat)....

Data were output by g software (Micro-g Lacoste, Inc.) version 9.12.04.23. A correction for laser-frequency drift was applied, based on regular calibration of the HeNe laser used in the A-10 against an iodine-stabilized laser. A second soil-moisture correction was applied based on satellite soil-moisture measurements, an infiltration model, and the elevation...
