RESEARCH
Hongqing Wang's expertise is ecosystem modeling coupled with field observation, application of remote sensing, GIS, GPS and spatial statistics. His current research areas include integrated modeling, monitoring and detecting changes in hydrodynamics, sediment transport, morphology, water quality, landscape, surface elevation, vegetation (composition/distribution and productivity), biological population dynamics (e.g., oysters), and soil biogeochemistry (C, N, P, S) in wetland ecosystems due to natural disturbances (e.g., climate change, land subsidence, storms) and human activities (e.g., land use, water management, ecosystem restoration). Wang is one of the developers of Wetland Morphology Model for Louisiana's 2012 Coastal Master Plan (http://www.coastalmasterplan.louisiana.gov/) for coastal Louisiana ecosystem restoration, sponsored by State of Louisiana's Coastal Protection and Restoration Authority. He has also been involved in monitoring programs such as Coastwide Reference Monitoring System and Louisiana Coastal Area program for adaptive management. He is currently an Associate Editor for Wetlands.

Science and Products
Impacts of coastal and watershed changes on upper estuaries: causes and implications of wetland ecosystem transitions along the US Atlantic and Gulf Coasts
Estuaries and their surrounding wetlands are coastal transition zones where freshwater rivers meet tidal seawater. As sea levels rise, tidal forces move saltier water farther upstream, extending into freshwater wetland areas. Human changes to the surrounding landscape may amplify the effects of this tidal extension, impacting the resiliency and function of the upper estuarine wetlands. One...
Model Improvements for Louisiana’s 2023 Coastal Master Plan
The Louisiana Coastal Protection and Restoration Authority’s Coastal Master Plan is a blueprint for responding to environmental changes. As part of the agency’s continued engagement, USGS supports model developments and improvements for the 2023 Coastal Master Plan.
Alabama Barrier Island Restoration Assessment
This project is a collaborative effort between the USGS, U.S. Army Corps of Engineers (USACE), and the State of Alabama funded by National Fish and Wildlife Foundation (NFWF) to investigate viable, sustainable restoration options that protect and restore the natural resources of Dauphin Island, Alabama. The project is focused on restoration options that protect and restore habitat and living...
Collecting Ecological Data and Models of Living Shoreline Restoration Projects
Developing effective living shoreline restoration projects that can withstand hurricanes and storms requires a better understanding of how restoration structures reduce the impact of wave and current energy on marsh edges in estuaries and bays. Without this knowledge, existing living shoreline projects and adaptive management measures are more likely to fail, decreasing the possibility for...
Alabama Barrier Island Restoration Assessment at Dauphin Island
Dauphin Island, Alabama, is the only barrier island providing protection to much of Alabama's coastal natural resources. Severely impacted by repeated extreme events, like Hurricane Katrina and Deepwater Horizon oil spill, USGS and partners are conducting a joint study to evaluate the feasibility of certain alternatives to increase resiliency and sustainability of the island.
Modeling Tidal Freshwater Forested Wetlands (TFFW) Habitat Changes for Land Management
As tidal freshwater forested wetlands - TFFWs - are influenced by salinty due to salt water intrusion, they may experience changes in plant community composition, growth, and productivity. Models are needed to predict vegetation community change or dieback, as well as changes in carbon sequestration and storage due to changing climate, drought, changes in freshwater discharge, elevated carbon...
Predicting the Long-Term Impact of Hurricane Sandy on Spatial Patterns of Wetland Morphology in Salt Marshes of Jamaica Bay, New York
USGS scientists are working with collaborators to understand how Hurricane Sandy impacted wetlands in Jamaica Bay, New York.
Integrated Modeling of Coastal Processes and Linkages to Management Applications
Coastal wetlands provide valuable ecosystem services such as wave attenuation, surge reduction, carbon sequestration, wastewater treatment, and critical habitats for endangered fish and wildlife species. However, wetland loss threatens the capacity of coastal wetlands to provide these ecosystem services.
Influence of Sea-Level Rise on Wetland Vegetation Community Structure, Primary Productivity, Organic Matter Decomposition and Carbon Storage
This study will employ a space for time substitution to show long-term effects of rising sea-level and increasing salinity on vegetation community structure, primary production and decomposition. Productivity and decomposition rates will be estimated for four wetland plant community types defined by salinity zones and dominant plant species.
Forecasting Biological Vulnerabilities: Modeling Jamaica Bay Wetland Morphology under Future Hurricanes
In light of the increase in hurricane frequency and intensity, there is concern about the resilience and sustainability of coastal wetlands. Models can be used to investigatethe impacts of future hurricanes on wetland morphology along the northeast coasts in areas like Jamaica Bay, New York, an area impacted by Hurricane Sandy.
Long-Term Carbon Burial in Marshes of the Mississippi River Delta
Wetlands along the Gulf of Mexico coast play an important role in the global carbon cycle, but as they rapidly convert to open water, their potential for carbon storage is declining. USGS is working to provide accurate, long-term marsh soil carbon sequestration rates.
Modeling structural mechanics of oyster reef self-organization including environmental constraints and community interactions
Self-organization is a process of establishing and reinforcing local structures through feedbacks between internal population dynamics and external factors. In reef-building systems, substrate is collectively engineered by individuals that also occupy it and compete for space. Reefs are constrained spatially by the physical environment, and by...

Predicting barrier island habitats and oyster and seagrass habitat suitability for various restoration measures and future conditions for Dauphin Island, Alabama
Barrier islands, such as Dauphin Island, Alabama, provide numerous invaluable ecosystem services including storm damage reduction and erosion control to the mainland, habitat for fish and wildlife, carbon sequestration in marshes, water catchment and purification, recreation, and tourism. These islands are dynamic environments that are gradually...
Enwright, Nicholas M.; Wang, Hongqing; Dalyander, P. Soupy; Elizabeth Godsey Modeling soil porewater salinity response to drought in tidal freshwater forested wetlands
There is a growing concern about the adverse effects of saltwater intrusion via tidal rivers, streams and creeks into tidal freshwater forested wetlands (TFFW) due to sea‐level rise (SLR) and intense and extended drought events. However, the magnitude and duration of porewater salinity in exceedance of plant salinity stress threshold (2 practical...

Constructed oyster reefs (CORs) provide shore protections and habitats for fish and shellfish communities via wave energy attenuation. However, the processes and mechanism of CORs on wave attenuation remain unclear, thus limiting the effective assessment of CORs for shoreline protection.

Barrier islands are dynamic environments because of their position along the marine–estuarine interface. Geomorphology influences habitat distribution on barrier islands by regulating exposure to harsh abiotic conditions. Researchers have identified linkages between habitat and landscape position, such as elevation and distance from shore, yet...

Barrier island habitat map and vegetation survey—Dauphin Island, Alabama, 2015
Barrier islands are dynamic environments due to their position at the land-sea interface. Storms, waves, tides, currents, and relative sea-level rise are powerful forces that shape barrier island geomorphology and habitats (for example, beach, dune, marsh, and forest). Hurricane Katrina in 2005 and the Deep Water Horizon oil spill in 2010 are two...

There remains much debate regarding the perceived tradeoffs of using freshwater and sediment diversions for coastal restoration in terms of balancing the need for wetland restoration versus preserving eastern oyster (Crassostrea virginica) production. Further complicating the issue, climate change-induced sea-level rise (SLR) and land subsidence...
