Kara Doran is an oceanographer with the USGS St. Petersburg Coastal and Marine Science Center. Her area of expertise is understanding and forecasting storm impacts to sandy coastlines.
For the last decade, she has been part of the National Assessment of Storm-Induced Coastal Change Hazards project. Her work in this project includes:
- Producing real-time forecasts and scenario-based predictions of coastal total water level and geomorphic change during storms
- Analysis of lidar-derived measures of coastal change
Since 2018 she has acted as the coastal change hazards liaison to the the USGS Storm Team and has worked in partnership with other federal agencies such as US Army Corps of Engineers (USACE) and National Oceanic and Atmospheric Administration (NOAA) to provide the nation scientifically rigorous information to assess national vulnerability to coastal change hazards.

Making USGS/NOAA Total Water Level and Coastal Change Forecast data accessible through user-friendly interfaces
The Total Water Level and Coastal Change Forecast delivers 6-day forecasts of hourly water levels and the probability of waves impacting dunes along 5000 km of sandy coasts along the Atlantic and Gulf of Mexico and will soon expand to the Pacific. These forecasts provide needed information to local governments and federal partners and are used by the USGS to place sensors before a storm. The forecStorm-Induced Coastal Change

The USGS National Assessment of Coastal Change Hazards project aims to identify areas of the nation's coastline that are most vulnerable to extreme storms and long-term shoreline change.

Characterizing storm-induced coastal change hazards along the United States West Coast
Traditional methods to assess the probability of storm-induced erosion and flooding from extreme water levels have limited use along the U.S. West Coast where swell dominates erosion and storm surge is limited. This effort presents methodology to assess the probability of erosion and flooding for the U.S. West Coast from extreme total water levels (TWLs), but the approach is applicable to coastalPredicted sea-level rise-driven biogeomorphological changes on Fire Island, New York: Implications for people and plovers
Forecasting biogeomorphological conditions for barrier islands is critical for informing sea-level rise (SLR) planning, including management of coastal development and ecosystems. We combined five probabilistic models to predict SLR-driven changes and their implications on Fire Island, New York, by 2050. We predicted barrier island biogeomorphological conditions, dynamic landcover response, pipingDistinguishing between regression model fits to global mean sea level reconstructions
Global mean sea level (GMSL) has been rising since the last century, posing a serious challenge for the coastal areas. A variety of regression models have been utilized for determining GMSL rise over the past one hundred years, resulting in a large spread of sea level rise rates and multidecadal variations. In this study, we develop a new nonparametric noise model that is data-dependent and considHurricane Matthew: Predictions, observations, and an analysis of coastal change
Hurricane Matthew, the strongest Atlantic hurricane of the 2016 hurricane season, made land-fall south of McClellanville, S.C., around 1500 Coordinated Universal Time (UTC) on October 8, 2016. Hurricane Matthew affected the States of Florida, Georgia, South Carolina, and North Carolina along the U.S. Atlantic coastline. Numerous barrier islands were breached, and the erosion of beaches and dunes oForecasts of coastal change hazards
Model predictions of severe storm impacts provide coastal residents, emergency managers, and partner organizations valuable predictive information for planning and response to extreme storm events. The foundation of this work is a USGS-developed numerical model to forecast storm-induced coastal water levels and expected coastal change, including dune erosion, overwash, and inundation. The model isComparing 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 one survey with complex beach morphology.

This chapter focuses on the morphologic variability of barrier islands and on the differences in storm response. It describes different types of barrier island response to individual storms, as well as the integrated response of barrier islands to many storms. The chapter considers case study on the Chandeleur Island chain, where a decadal time series of island elevation measurements have document - News
