My interests are in geomorphology and related fields such as fluvial hydrology, sediment transport, stream and wetland restoration, Quaternary paleoclimate, and geographic information systems (GIS). I also have experience with computer simulations of global climate (using general circulation models, or GCMs), downscaling global-climate estimates to local scales (statistical climate models and dynamical models such as the Weather Research and Forecasting Model, or WRF), and modeling land-atmosphere interactions and feedbacks.

Historical Water-Use in Florida
The Florida Water-Use Program is an ongoing cooperative project between the United States Geological Survey (USGS), Caribbean-Florida Water Science Center and the Florida Department of Agriculture and Consumer Services (FDACS), Office of Agricultural Water Policy (http://www.freshfromflorida.com/Divisions-Offices/Agricultural-Water-Policy). This ongoing cooperative project began in Florida in 1984...Actual Evapotranspiration for Florida
Evapotranspiration is a large component of the Florida water budget – generally second only to rainfall, but exceeding rainfall and all other components during droughts. The prominence of evapotranspiration highlights the need to accurately quantify this hydrologic component in quantitative analyses of watershed hydrology. Spatio-temporal estimates of evapotranspiration throughout Florida are...CFWSC Strategic Science Plan - Communication, Information Management, and Science Support

The National Water-Use Information Program of the U.S. Geological Survey (USGS) is a cooperative program designed to compile, store, and disseminate water-use information locally and nationwide. Since 1950, the USGS has compiled data at 5-year intervals on amounts of water used in homes, businesses, and on farms in the United States, and has described how that use changed with time.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...Chemistry of Uncontaminated Alluvial Deposits of the Cheyenne and Belle Fourche Rivers, South Dakota

Development of projected depth-duration frequency curves (2050–89) for south Florida
Planning stormwater projects requires estimates of current and future extreme precipitation depths for events with specified return periods and durations. In this study, precipitation data from four downscaled climate datasets are used to determine changes in precipitation depth-duration-frequency curves from the period 1966–2005 to the period 2050–89 primarily on the basis of Representative ConceAuthorsMichelle M. Irizarry-Ortiz, John F.

Changes in future precipitation are of great importance to climate data users in South Florida. A recent U.S. Geological Survey workshop, “Increasing Confidence in Precipitation Projections for Everglades Restoration,” highlighted a gap between standard climate model outputs and the climate information needs of some key Florida natural resource managers. These natural resource managers (hereafterAuthorsJohnna Infanti, Ben P. Kirtman, Nicholas Aumen, John F.

Because precipitation changes can significantly affect the Everglades ecosystem, characterization of precipitation projection uncertainty is important for resource management decisions, and reduction of uncertainAuthorsJohnna Infanti, Ben P.

Gold mining operations in the northern Black Hills of South Dakota resulted in the discharge of arsenopyrite-bearing mine tailings into Whitewood Creek from 1876 to 1977. Those tailings were transported further downstream along the Belle Fourche River, the Cheyenne River, and the Missouri River.

The Lower Brule Reservation in central South Dakota is losing land because of shoreline erosion along Lake Sharpe, a reservoir on the Missouri River, which has caused detrimental effects for the Lower Brule Sioux Tribe including losses of cultural sites, recreation access points, wildlife habitat, irrigated cropland, and landmass. To better understand and quantify shoreline erosion, the Lower BrulAuthorsRyan F. Thompson, John F. StammSources of groundwater and characteristics of surface-water recharge at Bell, White, and Suwannee Springs, Florida, 2012–13
Discharge from springs in Florida is sourced from aquifers, such as the Upper Floridan aquifer, which is overlain by an upper confining unit that locally can have properties of an aquifer. Water levels in aquifers are affected by several factors, such as precipitation, recharge, and groundwater withdrawals, which in turn can affect discharge from springs. Therefore, identifying groundwater sourcesAuthorsJohn F. Stamm, W.

Mountain snowpack is an important contributor to runoff in the Upper Missouri River Basin; for example, high amounts of winter and spring precipitation in the mountains and plains in 2010–11 were associated with the peak runoff of record in 2011 in the Upper Missouri River Basin. To project trends in peak mountain snowpack and runoff in the upcoming decades, multiple linear regression models of peAuthorsJohn F.

Upward trends in precipitation and streamflow have been observed in the northeastern Missouri River Basin during the past century, including the area of eastern South Dakota. Some of the identified upward trends were anomalously large relative to surrounding parts of the northern Great Plains.

Karst aquifers—formed by the dissolution of soluble rocks such as limestone—are critical groundwater resources in North America, and karst springs, caves, and streams provide habitat for unique flora and fauna. Springflow and groundwater levels in karst terrane can change greatly over short time scales, and therefore are likely to respond rapidly to climate change.
