Geoscience provided a range of wave forces on a raised seawall for Overstreet Associates. Waves were modeled using the Coastal Modeling System with wave values that were selected based on a 20-year review of hourly wave conditions and water levels. Wave forces were calculated using the Goda Formula for Forces on Walls from Breaking and Non-Breaking Waves and the Coastal Engineering Manual (CEM).

Read MoreThe Phase I project used a small marsh island on the Whale Branch creek to model processes that control marsh health and evolution in the larger Broad River/Port Royal Sound habitats.
Read MoreThis study details the degree that the forested and palustrine forest floodplains along the Black, Waccamaw and the Pee Dee Rivers are contributing to lower flooding for crops and infrastructure in the basins.
Read MoreThis pilot study examined the water storage/flood resiliency value of lands upstream of urban/suburban centers under riverine dominated flooding. The goal was to develop a process that could be applied to other areas in the Southeast US.
Read MoreGeoscience Consultants worked with the Lowcountry Council of Governments (LCOG) in developing a forward looking watershed management plan for five watersheds in the Lower Savannah. The area is directly adjacent to a major freshwater withdrawal that provides water to hundreds of thousands of people.
Read MoreThe North Coast project in Georgetown and Horry Counties (SC) grew from TNC’s Coast Summit in 2016 where riverine flooding was highlighted as a problem that held opportunity for nature based mitigation projects. Geoscience Consultants was hired to provide an understanding of localized flood risk at present and under future climate change. This information will help community stakeholders identify locations where green infrastructure can be used to mitigate increasing flooding issues.
Read MoreThis project focused on identifying the potential infrastructure problems that will exist as sea level rise (SLR) occurs and determining how those effects can be minimized or mitigated to ensure that the needs of both the local communities and the military facilities are accommodated. This is particularly significant in the Beaufort area due to the fact that water and sewer services are provided to the military facilities by the same regional provider that serves the local communities; and local roads, highways and bridges provide the only access to MCAS Beaufort and MCRD Parris Island.
Read MoreGeoscience Consultants was hired to examine sediment transport into a local navigational channel. The study revealed that a cause of the siltation in the channel was actually a lack of sediment. This study highlights the intertwined nature of coastal habitats and human use.
Read MoreGeoscience performed a technical review of marsh migration models, the fundamental data sets and various parameters that drive model outputs.
Read MoreThe work was performed to assess the effects of human modifications (port development) on the nearby natural shorelines including wetlands. Shoreline changes in these settings are complex and spatially inconsistent, unlike sandy open-coast shorelines. In order to both densely measure the change and smooth high frequency variation a node to node analysis was performed
Read MoreGeoscience Consultants was hired to assess the historic shoreline trends and define the various sediment transport mechanisms at a hot-spot along South Padre Island. Based on the analysis, a low profile groin conceptual design using geo-textiles was also developed.
Read MoreStump Pass State Park, FL was the site of a low-profile innovative groin field installed following the re-alignment of the local down-drift inlet. Geoscience Consultants was hired by the prime contractor to assess the performance of the installation.
Read MoreGeoscience reviewed the potential effects from a proposed offshore sill/breakwater at a boat launch for a local engineering firm in Charleston SC
Read MoreA Small-craft Harbor fronting the Mississippi Sound was proposed following Hurricane Katrina; Geoscience Consultants was asked to assess/document the potential environmental impacts related to sediment transport and water quality prior to construction
Read MoreGeoscience worked with a local Charleston, SC engineering firm to perform a review of past shoreline/littoral changes and assess potential living shoreline stabilization techniques for a waterfront park
Read MoreAn analysis was performed on the potential modifications to sediment transport and the associated conditions related with the planned construction of a new jetty on the eastern entrance of a harbor in Mississippi.
