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 MoreGeoscience worked with Sherwood Design Engineers to provide a host of flooding risk information, including pluvial (rain), shallow coastal, and tropical storms.
Read MoreGeoscience Consultants, LLC (Geoscience) was contracted by McSweeney Engineers to examine some of the historical and physical changes to the bluff shoreline at Magnolia Plantation along the Ashley River. To help answer these questions Geoscience leveraged about 15 years (2006/7-2020) of lidar data to assess elevation trends along the bluff shoreline in concert with the lithology and morphology of the bluff.
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 Consultants generated time-based inundation risk map outputs of present and future (up to 2100) inundation from SLR at mean higher high water, shallow coastal flooding, category 1 hurricanes, and still-water annual storm surge in the Salem Sound Coastwatch communities of Northeast Massachusetts.
Read MoreGeoscience worked as a subcontractor for the NOAA Office for Coastal Management on an accuracy assessment of the Benthic mapping of San Francisco Bay. The work included comparison of draft benthic map results with temporal imagery and in situ measurements of benthic vegetation and littoral land cover.
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 MoreTo assess habitat restoration needs Geoscience Consultants was hired to examine marsh substrate elevation differences caused by the existence of a causeway running across the bayou. The reduced flow inland of the causeway may have limited natural accretion thus limiting the ability of the marsh substrate to maintain equilibrium with the optimum growth conditions.
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
