“…11 Levees were assumed to cost $1.6 million per kilometer ($500 per linear foot) (Sorensen et al, 1984). As an alternative, we considered protection with bulkheads, whose cost is only $0.42 million per kilometer ($130 per foot) (Sorensen et al, 1984).…”

“…As an alternative, we considered protection with bulkheads, whose cost is only $0.42 million per kilometer ($130 per foot) (Sorensen et al, 1984). In the case of areas that already have bulkheads, we netted out the costs that would be incurred without sea level rise due to routine replacement, using the standard engineering assumption that that bulkhead costs increase with bulkhead height raised to the 1.5 power.…”

“…The Delaware River Basin Commission, for example, protects Philadelphia's freshwater intake on the river--as well as New Jersey aquifers recharged by the river--from excessive salinity by storing water in reservoirs during the wet season and releasing it during droughts, forcing the saltwater back toward the sea (Hull and Titus, 1986). Other communities have protected coastal aquifers by erecting underground barriers and by maintaining freshwater pressure through the use of impoundments and injection wells (Sorensen et al, 1984). …”

“…They provide slope stabilization in uneven terrain, used in contexts like highway construction. In ecological applications, they can aid with restoration of degraded environments in the form of check dams (walls anchored in the ground that mitigate erosion by slowing water velocity during storm surges) [1], as well as addressing problems associated with sea level rise such as erosion, inundation, and salinity intrusion by forming structures such as bulkheads, perpendicular groins, offshore breakwaters, and seawalls [2], [3].…”

Soil stabilization is a fundamental component of nearly all construction projects, ranging from commercial construction to environmental restoration projects. Previous work in autonomous construction has generally not considered these essential stabilization and anchoring tasks. In this work we present Romu, an autonomous robot capable of building continuous linear structures by using a vibratory hammer to drive interlocking sheet piles into soil. We report on hardware parameters and their effects on pile driving performance, and demonstrate autonomous operation in both controlled and natural environments. Finally, we present simulations in which a small swarm of robots build with sheet piles in example terrains, or apply an alternate spray-based stabilizing agent, and quantify the ability of each intervention to mitigate hydraulic erosion.

Coastal saltwater intrusion (SWI) is one key factor affecting the hydrology, nutrient transport, and biogeochemistry of coastal marsh landscapes. Future climate change, especially intensified sea level rise (SLR), is expected to trigger SWI to encroach coastal freshwater aquifers more intensively. Numerous studies have investigated decadal/century scale SWI under SLR by assuming a static coastal landscape topography. However, coastal marshes are highly dynamic systems in response to SLR, and the impact of coastal marsh evolution on SWI has received very little attention. Thus, this study investigated how coastal marsh evolution affects future SWI with a physically-based coastal hydro-eco-geomorphologic model, ATS (Advanced Terrestrial Simulator). Our synthetic modeling experiments showed that it is very likely that the marsh elevation increases with future SLR, and a depression zone is formed due to the different marsh accretion rates between the ocean boundary and the inland. We found that, compared to the cases without marsh evolution, the marsh accretion may significantly reduce the surface saltwater inflow at the ocean boundary, and the evolved topographic depression zone may prolong the residence time of surface ponding saltwater, which causes distinct subsurface salinity distributions. We also found that the marshland may become more sensitive to the upland groundwater table that controls the freshwater flux to the marshes, compared with the cases without marsh evolution. This study demonstrates the importance of marsh evolution to the freshwater-saltwater interaction under sea level rise and can help improve our predictive understanding of the vulnerability of the coastal freshwater system to sea level rise.
