Topographic Survey of Select Erosional Features within Fern Ridge Lake, Oregon, 2023 and 2024 Topographic Survey of Select Erosional Features within Fern Ridge Lake, Oregon, 2023 and 2024
Topographic data were collected along select erosional features within or adjacent to channels exposed in Fern Ridge Lake, Oregon, in 2023 and 2024 during low pool. Measurements were focused on features that displayed evidence of past or ongoing fluvial erosion and included landforms such as rills, gulleys and channel segments with knickpoints. The survey data were collected during...

Developing a land change monitoring capability and supporting training data strategy for select international sites: First Outputs Developing a land change monitoring capability and supporting training data strategy for select international sites: First Outputs
The monitoring of landscape change is widely recognized as an important component towards understanding how the Earth changes and the impacts of, and to, human societies. The U.S. Geological Survey (USGS) Earth Resources Observation and Science (EROS) Center has been developing a monitoring capability suitable for monitoring land change along with climate-related factors towards the long...
MODFLOW–6 model of the Shell Valley aquifer, Belcourt, North Dakota, 1980-2022 MODFLOW–6 model of the Shell Valley aquifer, Belcourt, North Dakota, 1980-2022
A MODFLOW-6 groundwater flow model of the Shell Valley aquifer near the Turtle Mountain Band of the Chippewa Indians land area representation in northern North Dakota was constructed to improve the understanding and management of the water-supply resources. The model area included sub-watersheds containing the extent of the Shell Valley aquifer approximately between the towns of St. John...
