Caribbean-Florida Water Science Center Watercams for Florida
Webcams have been installed at several real-time stream-gaging sites. The webcams provide valuable information to the National Weather Service, emergency managers, and area residents to evaluate real-time conditions in river environments during storms. The visual record of flooding and other river events also provides valuable research data for the USGS. Many of these webcam installations are...
Water-Use in Florida
Consistent and accurate statewide water-use data are essential for the sound management of Florida's water resources. The five water management districts (WMD), which are the primary collectors of water-use information, tailor their water use programs to each of their own needs and priorities. Consequently, within the State, there are several different levels of data collection, storage,...

Simulating wave runup on an intermediate–reflective beach using a wave-resolving and a wave-averaged version of XBeach
The prediction of wave runup, as well as its components, time-averaged setup and the time-varying swash, is a key element of coastal storm hazard assessments, as wave runup controls the transitions between morphodynamic response types such as dune erosion and overwash, and the potential for flooding by wave overtopping. While theoretically able to...

The Everglades Depth Estimation Network (EDEN) is an integrated network of water-level gages, interpolation models that estimate daily water-level data at ungaged locations, and applications that generate derived hydrologic data across the freshwater part of the Greater Everglades landscape. Version 3 (V3) of the EDEN interpolation surface-...
Haider, Saira; Swain, Eric; Beerens, James; Petkewich, Matthew; McCloskey, Bryan; Henkel, HeatherPotentiometric surfaces, 2011–12, and water-level differences between 1995 and 2011–12, in wells of the “200-foot,” “500-foot,” and “700-foot” sands of the Lake Charles area, southwestern Louisiana
Water levels were determined in 90 wells to prepare 2011–12 potentiometric surfaces focusing primarily on the “200-foot,” 500-foot,” and “700-foot” sands of the Lake Charles area, which are part of the Chicot aquifer system underlying Calcasieu and Cameron Parishes of southwestern Louisiana. These three aquifers provided 34 percent of the total...
White, Vincent E.; Griffith, Jason M.Modeling soil porewater salinity in mangrove forests (Everglades, Florida, USA) impacted by hydrological restoration and a warming climate
Hydrology is a critical driver controlling mangrove wetlands structural and functional attributes at different spatial and temporal scales. Yet, human activities have negatively affected hydrology, causing mangrove diebacks and coverage loss worldwide. In fact, the assessment of mangrove water budgets, impacted by natural and human disturbances,...
Zhao, Xiaochen; Rivera-Monroy, Victor H.; Wang, Hongqing; Xue, Zuo; Tsai, Cheng-Feng; Willson, C. S.; Castañeda-Moya, E.; Twilley, Robert R.Observed and modeled mercury and dissolved organic carbon concentrations and loads at control structure S-12D, Florida Everglades, 2013–17
Mercury (Hg) has been a contaminant of concern for several decades in South Florida, particularly in the Florida Everglades. The transport and bioavailability of Hg in aquatic systems is intimately linked to dissolved organic carbon (DOC). In aquatic systems, Hg can be converted to methylmercury (MeHg), which is the form of Hg that bioaccumulates...

Slightly brackish groundwater contaminated by polycyclic aromatic hydrocarbons (PAHs) at a Superfund site in the Central Valley of California was pumped from 250 feet below land surface to a water storage tank using solar power and then gravity‐fed into 18, 330‐gallon intermediate bulk containers (totes) as follows:(1)Five totes contained planting...
Landmeyer, James E.; Rock, Steven; Freeman, John; Nagle, Greg; Samolis, Mark; Levine, Herb; Cook, Anna-Marie; O'Neill, HarryMethods for estimating selected low-flow frequency statistics and mean annual flow for ungaged locations on streams in Alabama
Streamflow data and statistics are vitally important for proper protection and management of the water quality and water quantity of Alabama streams. Such data and statistics are generally available at U.S. Geological Survey streamflow-gaging stations, also referred to as streamgages or stations, but are often needed at ungaged stream locations....
Feaster, Toby D.; Kolb, Katharine R.; Painter, Jaime A.; Clark, Jimmy M.Stressor identification framework of biological impairment in Mississippi streams to support watershed restoration and TMDL development
The Clean Water Act (CWA) requires States to identify waters that are impaired for designated uses. These waters are published through a State’s §303(d) list. The CWA also requires that a total maximum daily load (TMDL) be completed for each water body to calculate the maximum amount of contaminants that can be present in that water body and still...
Hicks, Matthew B.; Cartwright, Jennifer M.How plants influence resilience of salt marsh and mangrove wetlands to sea-level rise
This review evaluates the importance of plants and associated biological processes in determining the vulnerability of coastal wetlands to sea-level rise. Coastal wetlands occur across a broad sedimentary continuum from minerogenic to biogenic, providing an opportunity to examine the relative importance of biological processes in wetland...
Cahoon, Donald R.; McKee, Karen L.; James MorrisUsing boosted regression tree models to predict salinity in Mississippi embayment aquifers, central United States
High salinity limits groundwater use in parts of the Mississippi embayment. Machine learning was used to create spatially continuous and three‐dimensional predictions of salinity across drinking‐water aquifers in the embayment. Boosted regression tree (BRT) models, a type of machine learning, were used to predict specific conductance (SC) and...
Knierim, Katherine J.; Kingsbury, James A.; Haugh, Connor J.; Ransom, Katherine MarieThe roles of storminess and sea level rise in decadal barrier island evolution
Models of alongshore sediment transport during quiescent conditions, storm‐driven barrier island morphology, and poststorm dune recovery are integrated to assess decadal barrier island evolution under scenarios of increased sea levels and variability in storminess (intensity and frequency). Model results indicate barrier island response regimes of...
Passeri, Davina L.; Dalyander, P. Soupy; Long, Joseph W.; Mickey, Rangley C.; Jenkins, Robert L.; Thompson, David M.; Plant, Nathaniel G.; Godsey, Elizabeth; Gonzalez, VictorEffects of water level alteration on carbon cycling in peatlands
Globally, peatlands play an important role in the carbon (C) cycle. High water level is a key factor in maintaining C storage in peatlands, but water levels are vulnerable to climate change and anthropogenic disturbance. This review examines literature related to the effects of water level alteration on C cycling in peatlands to summarize new...

New low-altitude aerial photos of Southeastern beaches taken before and after Hurricane Matthew passed offshore show a new storm-cut inlet, and roads, dunes and structures lost.
The heavy rains and storm surge Hurricane Matthew produced caused severe flooding in many parts of the south east, resulting in almost 40 peak flood records. As the flood waters continue to recede from some affected areas, the U. S. Geological Survey will continue its efforts to record this historic flooding.
