Background / Problem – The City of Ithaca, Tompkins County, N.Y., is in the process of developing a flood management plan for the streams that flow through the City. Flooding in the City is caused by a variety of distinct and sometimes interconnected reasons. Flooding often is a result of snowmelt and rain during the winter and spring. Slow ice-melt and breakup can lead to ice jams and subsequent flooding. Flash floods are produced by summer thunderstorms. All of these flood types are compounded by two factors: the storm-sewer system in the City and the elevation of Cayuga Lake. The storm sewers drain to the nearby streams at points below the tops of the streambanks. Because the streamward ends of the storm sewers...

Water-surface elevation measurements were collected in March 2015 along the upper Willamette River, Oregon, between Eugene to Corvallis. These surveys were collected over a small range of discharges using a real time kinematic global positioning system (RTK-GPS) on a motorboat traveling "on plane" along the river. These datasets were collected for equipment calibration and validation for the National Aeronautics and Space Administration’s (NASA) Surface Water and Ocean Topography (SWOT) satellite mission. This is one of multiple survey datasets that will be released for this effort.

River bathymetry surveys were collected in the summer and fall of 2016 along the lower Chetco River, Oregon. These surveys were collected using a real time kinematic global positioning system (RTK-GPS) and an echo sounder mounted on a motorboat and also behind a kayak at various cross sections and longitudinal profiles along the river. These datasets were collected in support of a funded effort investigating the cause of salt water intrusion that has taken place at the water intake facility for Harbor City, Oregon. The surveys were collected at sections approximately 0.4 river miles downstream to 0.8 river miles upstream of the Harbor City water intake structure and also at the city of Brookings water intake facility,...

The supplemental data presented here contains raster data in .tif format of the empirically estimated mean annual (1987-2015) net evapotranspiration (ETnet) for the Harney Basin Groundwater Evapotranspiration Area. The final mean annual ETnet estimate for the Harney Basin was determined using both empirical and physics-based methods. The final ETnet estimate was combined with additional data to estimate groundwater discharge through evapotranspiration (ET) in the Harney Basin. See Garcia and others (2022) for a detailed description of how these data were estimated and evaluated.

This dataset was compiled to summarize discharge measurements from several published groundwater and surface-water studies in the Ozarks of southern Missouri and northern Arkansas. The discharge measurements were part of numerous USGS studies to assess interaction between streams and groundwater aquifers. A gaining stream is described as a surface-water stream that gains water from the groundwater aquifer and a losing stream is described as a surface-water stream that loses water to the groundwater aquifer. This product is intended to be used in surface-water and groundwater investigations assessing water quantity, quality, and availability. The product includes flow-line data digitized along National Hydrography...

This dataset, VegDischarge v1, represents a significant contribution to the understanding of hydrological dynamics across Africa from 2000 to 2021. It encompasses high-resolution (1km x 1km) monthly raster data of deep drainage, surface runoff, and total runoff, derived from the VegET (VegetationEvapoTranspiration) hydrological model (Senay et al., 2023). Additionally, routed discharge data (Mizukami et al., 2021) for over 63,000 river segments is provided, employing different routing algorithms (DW, KW, KWT, MC, and IRF) to demonstrate variability in river discharge patterns. This comprehensive dataset is stored in NetCDF and Shapefile formats, offering valuable insights for policymakers, stakeholders, and researchers...

Problem - The valley-fill deposits in Upper Buttermilk Creek/Danby Creek valleys are sources of water for many homeowners, farms, and small businesses that are in this valley. The aquifer was mapped by Miller (2000) and identified as one of the 17 aquifers in Tompkins County that needs to be studied in more detail. However, there is little geohydrologic data in the valley. A cluster of wells in Upper Buttermilk valley are finished in sand and gravel, indicating that there is a sand and gravel aquifer in, at least, part of the valley. The Upper Buttermilk Creek/Danby Creek valleys are "through valleys"-- a part of a valley where the bedrock floor rose to land surface and formed a preglacial surface-water divide....

The U.S. Geological Survey collected thermal image time series from five rivers in Alaska September 18–20, 2016, to support research on remote sensing of river discharge. The image time series were acquired from bridges across the Knik, Matanuska, Chena, and Salcha Rivers and Montana Creek using a FLIR SC8340 mid-infrared (3–5 microns) camera operated at a rate of 10 frames/second. The original FLIR *.ast format video files are provided in this data release. This data release supports the following article: Legleiter, C.J., Kinzel, P.J., and Nelson, J.M., 2017, Remote measurement of river discharge using thermal particle image velocimetry (PIV) and various sources of bathymetric information: Journal of Hydrology,...
