Mapping river flow from thermal images in approximately real time: Proof of concept on the Sacramento River, California, USA
Image velocimetry has become an effective method of mapping flow conditions in rivers, but this analysis is typically performed in a post-processing mode after data collection is complete. In this study, we evaluated the potential to infer flow velocities in approximately real time as thermal images are being acquired from an uncrewed aircraft system (UAS). The sensitivity of thermal image velocim
Field trials of an autonomous eDNA sampler in lotic waters
Environmental DNA (eDNA) analysis has become a transformative technology, but sample collection methods lack standardization and sampling at effective frequencies requires considerable field effort. Autonomous eDNA samplers that can sample water at high frequencies offer potential solutions to these problems. We present results from four case studies using a prototype autonomous eDNA sampler as pa
An evaluation of cyanobacterial occurrence and bloom development in Adirondack lakes
Cyanobacterial harmful algal blooms (cyanoHABs) have occurred in many low nutrient (oligotrophic) lakes in the northeastern United States. The Adirondack Park in New York is a large, mountainous region with many low nutrient lakes. There is a gap in understanding regarding whether cyanoHAB reporting data are truly reflective of the susceptibility of lakes to develop bloom conditions. We evaluated

Groundwater Flow Modeling - Long Island, New York
Numerical models provide a means to synthesize existing hydrogeologic information into an internally consistent mathematical representation of a real system or process, and thus are useful tools for testing and improving conceptual models or hypotheses of groundwater flow systems. The goal of this effort is to develop a regional model for the Long Island aquifer system to simulate changes in water...
Saltwater-Interface Mapping - Long Island, New York
Saltwater intrusion is the most common type of water-quality degradation in coastal-plain aquifers. In coastal areas, the hydraulic head under predevelopment (nonpumping) conditions is higher on land than in the surrounding saltwater embayments; thus, fresh groundwater flows seaward (from areas of high potential to areas of lower potential) and meets saltwater at an equilibrium point (interface)...
Hydrogeologic-Framework Mapping - Long Island, New York
Long Island is underlain by unconsolidated Holocene deposits, glacial deposits of Pleistocene age, and coastal-plain deposits of Late Cretaceous age. These sediments consist of gravel, sand, silt, and clay underlain by crystalline bedrock of early Paleozoic age (figure 2b). The bedrock is relatively impermeable, and forms the base of the groundwater-flow system on Long Island. The geologic and...
