Data

This dataset is a bathymetric and hydraulic structure survey of Whetstone Brook and two tributaries. The dataset consists of stream channel cross-section data and structural data for bridges, culverts, and dams.

This data release contains drainage basin characteristics and peak-streamflow trend and change-point results for 2,683 U.S. Geological Survey (USGS) streamgages in the conterminous U.S. Data include streamgage identification number, name, drainage area, latitude, longitude, percent urban land use, dam storage, streamgage classification, record completeness status, lag-1 autocorrelation...

This set of data includes four potential annual recharge grids for the State of Maine that were simulated using the Maine Soil-Water-Balance model for 1991 through 2015. The files include a grid representing the uncertainty in the potential recharge and a grid showing the annual average precipitation from the climate dataset that the simulation is based on. A 25-year simulation of...

The InterpretSELDM program is a graphical post processor designed to facilitate analysis and presentation of stormwater modeling results from the Stochastic Empirical Loading and Dilution Model (SELDM), which is a stormwater model developed by the U.S. Geological Survey in cooperation with the Federal Highway Administration. SELDM simulates flows, concentrations, and loads in stormflows...

Snow depth and snow water equivalent (SWE) measurements have been made at Sleepers River Research Watershed starting in 1960. Initial snowpack measurements were made by the Agricultural Research Service joined by the National Weather Service in 1966. Cold Regions Research and Engineering Laboratory started measuring the snowpack in 1979, followed by the U.S. Geological Survey from 1993...

The Highway-Runoff Database (HRDB) was developed by the U.S. Geological Survey (USGS), in cooperation with the Federal Highway Administration (FHWA) Office of Project Delivery and Environmental Review to provide planning-level information for decision makers, planners, and highway engineers to assess and mitigate possible adverse effects of highway runoff on the Nation's receiving waters...

Lithostratigraphic and hydrogeologic observations for the unconfined aquifer of western Cape Cod are limited near coastal groundwater-discharge areas. In spring 2015, a 310-foot-deep boring was drilled and a well was installed to 100 feet below land surface to facilitate detailed study of aquifer characteristics along the southern coast of Cape Cod. Characteristics of interest included...

Hydrologic data were collected in the nearshore lake-bottom sediments of five lakes on western Cape Cod, Massachusetts: Ashumet (Falmouth), Long (Centerville), Santuit (Mashpee), Shubael (Barnstable), and Snake (Sandwich) Ponds. Water budgets of flow-through glacial kettle lakes are commonly dominated by groundwater flow into and surface-water seepage out of the lake, and inputs and...

Maximum likelihood logistic regression (MLLR) is used to estimate drought probabilities for selected Northeast rivers and streams. Winter streamflows are used to estimate the chance of hydrologic drought during summer months. This application allows the display and query of these drought streamflow probabilities for Northeastern streams.

This data set contains U.S. Geological Survey (USGS) streamgage identification numbers, begin and end years of the periods of streamflow record tested, Sen slope trends in the annual minimum 7-day streamflow for the period of record tested, the p-values (significance) of the trends, and the trend Sen slopes standardized by the standard deviations of the residual errors defined as the...

This data release contains drainage basin characteristics and low-streamflow trend results for 2,482 U.S. Geological Survey (USGS) streamgages in the conterminous U.S. Data include streamgage identification number, name, drainage area, latitude, longitude, percent developed land use, percent crop land use, dam storage, streamgage classification, record completeness status, and trend...
