Discharge measurements, air temperature, water temperature, and gage height data for select stream monitoring locations across Pennsylvania and Maryland piedmont mixed agriculture 2023 Discharge measurements, air temperature, water temperature, and gage height data for select stream monitoring locations across Pennsylvania and Maryland piedmont mixed agriculture 2023
As part of a larger study examining stream conditions and the effect of best management practices in the Chesapeake Bay watershed, thirty small streams across the Pennsylvania and Maryland piedmont physiographic province were instrumented and monitored for gage height (water level), water temperature, and air temperature using Onset HOBO sensors from March to September 2023. In addition...
MODFLOW-NWT model used to simulate groundwater availability in the Salt Fork Arkansas River and Chikaskia River alluvial aquifers, northern Oklahoma, 1980–2020 MODFLOW-NWT model used to simulate groundwater availability in the Salt Fork Arkansas River and Chikaskia River alluvial aquifers, northern Oklahoma, 1980–2020
The U.S. Geological Survey (USGS), in cooperation with the Oklahoma Water Resources Board (OWRB), constructed a finite-difference numerical groundwater-flow model of the Salt Fork Arkansas River and Chikaskia River alluvial aquifers by using MODFLOW-2005 with the Newton formulation solver (MODFLOW-NWT). The model included the Chikaskia River alluvial aquifer, which is classified as a...
Model Archive Summary for acoustic derived suspended-fines concentration at 14211720 Willamette River at Portland, OR Model Archive Summary for acoustic derived suspended-fines concentration at 14211720 Willamette River at Portland, OR
This model archive summary describes the development and methods used to derive and compute a suspended-fines ( 0.0625 mm particle size) model at USGS site ID# 14211720, Willamette River at Portland. The suspended-fines equations will be used to create real-time estimates of concentration and load that will help science entities, managers, and others, monitor sediment transport in the...
Model Archive Summary for acoustic derived suspended-sediment concentration at 14211720 Willamette River at Portland, OR (ver. 2.0, May 2025) Model Archive Summary for acoustic derived suspended-sediment concentration at 14211720 Willamette River at Portland, OR (ver. 2.0, May 2025)
This model archive summary describes techniques and methods used to derive and compute a second version of a suspended-sediment model at USGS site14211720, Willamette River at Portland. The created suspended-sediment concentration equations will be used to create real-time estimates of concentration and load which are available through the National Water Information System. The time...
Model Archive Summary for acoustic derived suspended-sand concentration at 14211720 Willamette River at Portland, OR Model Archive Summary for acoustic derived suspended-sand concentration at 14211720 Willamette River at Portland, OR
This model archive summary describes the development and methods used to derive and compute a suspended-sand (> 0.0625 mm particle size) model at USGS site ID# 14211720, Willamette River at Portland. The suspended-sand equations will be used to create real-time estimates of concentration and load that will help science entities, managers, and others, monitor sediment transport in the...
Modeling marsh migration: User needs for decision-making collected in 2021 and 2023 Modeling marsh migration: User needs for decision-making collected in 2021 and 2023
The U.S. Geological Survey (USGS) conducted interviews of professionals who make decisions about marshes during the Salt Marsh Evolution along the South Atlantic Bight project (SAB project) and the Marsh Model Retrospective initiative. During the SAB project, an advisory committee of marsh model users were interviewed in June 2023 about what decisions they make about marshes and how they...
