Aquifer framework datasets for the Willamette Lowland basin-fill aquifer, Oregon and Washington Aquifer framework datasets for the Willamette Lowland basin-fill aquifer, Oregon and Washington

The Willamette Lowland basin-fill aquifers (hereinafter referred to as the Willamette aquifer) is located in Oregon and in southern Washington. The aquifer is composed of unconsolidated deposits of sand and gravel, which are interlayered with clay units. The aquifer thickness varies from less than 100 feet to 800 feet. The aquifer is underlain by basaltic-rock. Cities such as Portland...

Aquifer framework datasets used to represent the Ada-Vamoosa aquifer, Oklahoma Aquifer framework datasets used to represent the Ada-Vamoosa aquifer, Oklahoma

The Ada-Vamoosa aquifer resides in the Central Lowland Physiographic Province in east-central Oklahoma and ends at the Kansas State line. The aquifer underlies an area of about 2,300 square miles. The aquifer consists mainly of layers of fine to coarse-grained sandstone irregularly interbedded with shale and limestone. The rocks are in the Ada and the Vamoosa Groups are Pennsylvanian age...

Aquifer framework datasets used to represent the Marshall aquifer, Michigan Aquifer framework datasets used to represent the Marshall aquifer, Michigan

The Marshall aquifer underlies much of the Lower Peninsula of Michigan and has a maximum thickness of 493 feet (Lampe, 2009). The aquifer consists mainly of medium-grained sandstone and is overlain by Pennsylvanian-age rocks and glacial deposits and underlain by the Devonian-Mississippian-age confining unit. The Marshall aquifer is one of the most productive aquifers in the state where

Sensor data from debris-flow experiments conducted in June, 2016, at the USGS Debris-flow Flume, HJ Andrews Experimental Forest, Blue River, Oregon Sensor data from debris-flow experiments conducted in June, 2016, at the USGS Debris-flow Flume, HJ Andrews Experimental Forest, Blue River, Oregon

These data were collected as part of a long-term program of large-scale experimentation at the USGS debris-flow flume. The chief focus of the six experiments performed in 2016 and represented in this data set was twofold: (1) measurement of evolving basal stresses as the flume headgate opened, and (2) measurement of broadband seismic energy radiated by the moving debris flows. The...

Landslide Inventory for Kosrae, Federated States of Micronesia (FSM) 2005 - 2023 Landslide Inventory for Kosrae, Federated States of Micronesia (FSM) 2005 - 2023

Landslides hazards pose a serious threat to people and infrastructure in the Federated States of Micronesia (FSM). To develop a comprehensive understanding of the landslides hazards in FSM, the USGS-USAID Landslide Disaster Assistance Team (LDAT) has put together landslide inventories for each state using satellite imagery. Mapping was done using RGB satellite imagery from Maxar, Planet...
