A generalized least squares (GLS) technique was used with at-site n-day low-flow time series and frequencies, from SWToolbox (Kiang and others, 2018), and 14 basin characteristics (basin perimeter, drainage area, maximum basin elevation, mean total annual reference evapotranspiration, groundwater head, length of longest flow path, minimum basin elevation, runoff-curve number, relief, ruggedness, slope ratio, percentage of hydrologic soil type B, available water capacity, and total length of streams in a basin) for 28 selected streamflow gaging stations in Puerto Rico to calculate regional n-day low-flow frequency regression equations for ungaged stream locations. The GLS approach assigns weights based on uncertainty...

This child page contains eight csv files, site_flow, which contain daily streamflow values for each site. Each file includes a station identifier, date of observation, measured value of streamflow and qualifier code for the measured value. The format of the csv file (date format and column headings) is designed to meet the specific requirements of file format for R-QWTREND. If csv files are opened directly in excel, the format of the data can change. To ensure the data are in the proper format for R-QWTREND, files should be opened in a text editor. The "site" in site_flow can be cross-referenced to the main report by downloading the zipped folder HRtrend folder from child page, "Scripts to run R-QWTREND models and...
Additional data layers have been developed to supplement recently published information collected and developed for an investigation of shoreline erosion along the Lower Brule Reservation in Central South Dakota. The additional data layers presented in this data release include georeferenced 1965 single frame aerial photos, digitized shoreline features from the georeferenced 1965 images, digitized shoreline features from 2016 aerial imagery, and real-time kinematic surveys of shoreline features on selected reaches of the Lake Sharpe shoreline in 2018. This effort was completed by the USGS Dakota Water Science Center in cooperation with the Lower Brule Sioux Tribe, Tribal Preservation Office.
This child page contains a zipped folder which contains all items necessary to run geochemical models and produce results published in U.S. Geological Scientific Investigations Report 2022–5013 [Tatge, W.S., Nustad, R.A., and Galloway, J.M., 2022, Evaluation of Salinity and Nutrient Conditions in the Heart River Basin, North Dakota, 1970-2020: U.S. Geological Survey Scientific Investigations Report 2022-5013]. The main folder contains a readme.txt and a file called allsiteinfo.table.csv that can be used to learn how to use the files and reference sites to the main report. Also the main folder contains two folders Model Zone 1 and 2 which include a .pqi, .pqo, and .txt files that can be used to run the models and...

These data were released prior to the October 1, 2016 effective date for the USGS’s policy dictating the review, approval, and release of scientific data as referenced in USGS Survey Manual Chapter 502.8 Fundamental Science Practices: Review and Approval of Scientific Data for Release. This data set depicts land use and land cover from the 1970s and 1980s and has been previously published by the U.S. Geological Survey (USGS) in other file formats. This version has been reformatted to other file formats and includes minor edits applied by the U.S. Environmental Protection Agency (USEPA) and USGS scientists. This data set was developed to meet the needs of the USGS National Water-Quality Assessment (NAWQA) Program.
