Jeffrey W Riley

Jeff is an ecologist at the South Atlantic Water Science Center.

Much of his work has focused on the interactions of hydrology, geomorphology, and ecology. Recent research includes quantifying groundwater use by riparian forests, investigating flash drought impacts on forested ecosystems in the Southeast U.S., and using machine learning models to predict inundation dynamics in isolated wetlands.

Panola Mountain, Ga. Research Watershed: Small watershed studies

Small Watershed Studies at the Panola Mountain Research Watershed, Georgia

The Panola Mountain Research Watershed (PMRW) is a 41-hectare forested watershed in the southern Piedmont physiographic province near Atlanta, Georgia. The watershed contains a naturally regenerated second-growth forest on abandoned agricultural land, typical of the Piedmont. Research at PMRW is focused on how streamflow is generated, and in particular, on how water and solutes move from...

Stream habitat and geomorphic characteristics above and below culverts at selected sites in South Carolina (2017) Stream habitat and geomorphic characteristics above and below culverts at selected sites in South Carolina (2017)

This dataset contains six individual tabular data files. These tabular data files contain measurements of aquatic habitat features and stream channel geomorphology from 20 sites in the Piedmont and Upper Coastal Plain physiographic regions of South Carolina. Specifically, the dataset titled "bedform_slope" contains enumeration of occurrence of bedforms, or macro-habitat features, and...

Geospatial, continuous, and point measure data for a spatial and temporal assessment of back-barrier erosion on Cumberland Island National Seashore, Georgia, 2011-2013: Geospatial, continuous, and point measure data for a spatial and temporal assessment of back-barrier erosion on Cumberland Island National Seashore, Georgia, 2011-2013:

This data release contains four data files that were used to evaluate the conditions during which erosion occurred and the magnitude of erosional events. A single shapefile contains shoreline positions for five sites measured during the beginning and end of the project and projected shoreline positions based on the observed erosion rates. There are three .csv files that contain measured...

Standard operating procedure 1.2.16 wadeable stream reach-scale field data collection—version 1.0 Standard operating procedure 1.2.16 wadeable stream reach-scale field data collection—version 1.0

The following standard operation procedure (SOP) outlines the procedure for collecting physical habitat data from previously selected and benchmarked wadeable streams. The purpose of this SOP is to ensure that data are collected using methods that are consistent between reaches and years. Using the methods described in this SOP will also ensure that the data will be comparable to data...

The following standard operating procedure (SOP) outlines the process for setting up and configuring a total station to collect accurate x, y, and z coordinate data. Total stations allow accurate spatial data to be collected and tied to a permanent benchmark. These data can be used to detect small geomorphic changes between site surveys. Many different types of total stations and...

Widespread occurrence and potential for biodegradation of bioactive contaminants in Congaree National Park, USA Widespread occurrence and potential for biodegradation of bioactive contaminants in Congaree National Park, USA

Organic contaminants with designed molecular bioactivity, such as pesticides and pharmaceuticals, originate from human and agricultural sources, occur frequently in surface waters, and threaten the structure and function of aquatic and terrestrial ecosystems. Congaree National Park in South Carolina (USA) is a vulnerable park unit due to its location downstream of multiple urban and...

Species interactions and the effects of climate variability on a wetland amphibian metacommunity Species interactions and the effects of climate variability on a wetland amphibian metacommunity

Disentangling the role that multiple interacting factors have on species responses to shifting climate poses a significant challenge. However, our ability to do so is of utmost importance to predict the effects of climate change on species distributions. We examined how populations of three species of wetland-breeding amphibians, which varied in life history requirements, responded to a...
