Geophysical Characteristics of the Conterminous United States: Hydraulic Conductivity (µm/s) This raster depicts the percentage of lithological the hydraulic conductivity (in micrometers per second) of surface or near surface geology. We derived these rasters by calculating the average conductivity for each map unit in combined surficial-bedrock geologic maps. We used state geologic maps (Preliminary Integrated Geologic Map Databases for the United States, Open File Reports 2004-1355, 2005-1305, 2005-1323, 2005-1324, 2005-1325, 2005-1351, and 2006-1272), which depict surficial geology instead of bedrock when the surficial layers are sufficiently deep. For the state maps that do not incorporate surficial geology (i.e., midwestern states), we overlaid surficial geologic map units with thicknesses greater...

Relatively less is known about the ecological implications of ARs, particularly in the interior Southwest, where AR storms are less common. To address this gap, we compared a chronology of AR landfalls on the west coast between 1989-2011 and between 25-42.5ºN, to annual metrics of the Normalized Difference Vegetation Index (NDVI; an indicator of vegetation productivity) and daily-resolution precipitation data to assess influences of AR-fed winter precipitation on vegetation productivity across the southwestern...

Phosphorus, Fewer tags Silvies Valley Ranch Stream Restoration Sites, 1983-2016 These data describe the water year (October-September) precipitation and summer (JJA) NDVI for the riparian areas along four creeks on the Silvies Valley Ranch. Each of these creeks had a series of rock checkdams installed between 2006 and 2011 to stop incision and raise the mean water level. Data in this file are used to examine the relationship between water year precipiation and summer NDVI in these watersheds and how that relationship may have changed with the installation of the dams.
