Louisville Aquifer

The Louisville Water Company is using riverbank filtration wells to draw water from the Ohio River through the aquifer at their B.E. Payne Water Treatment Plant near Prospect, Kentucky. The northeast portion of the alluvium— a 6.4-mi reach running from Beargrass Creek upriver to Harrods Creek is an especially prolific water-bearing formation with the total groundwater storage in the area...

Bathymetric Surveys

Bathymetric surveys allow us to measure the depth of a water body as well as map the underwater features of a water body.  Multiple methods can be used for bathymetric surveys including multi-beam and single-beam surveys, ADCPs, sub-bottom profilers, and the Ecomapper Autonomous Underwater Vehicle. We use bathymetric surveys for many different types of research including flood inundation,...

Comparing methods used by the U.S. Geological Survey Coastal and Marine Geology Program for deriving shoreline position from lidar data

The U.S. Geological Survey Coastal and Marine Geology Program uses three methods to derive a datum-based, mean high water shoreline on open-ocean coasts from light detection and ranging (lidar) elevation surveys. This work compared the shorelines produced by the three methods for two different surveys: one survey with simple beach morphology, and...

Using partial aggregation in spatial capture recapture

Spatial capture–recapture (SCR) models are commonly used for analysing data collected using noninvasive genetic sampling (NGS). Opportunistic NGS often leads to detections that do not occur at discrete detector locations. Therefore, spatial aggregation of individual detections into fixed detectors (e.g., centre of grid cells) is an option to...
