Arc Surveying & Mapping was contracted to perform surveying services for a project to remedy bank erosion along the Hatchie River within the Lower Hatchie National Wildlife Refuge. They conducted an existing conditions survey using total stations and GPS to collect baseline data. Arc then provided layout for bank grading, stabilization, coffer dams, and a new cellular wall. They also placed grade stakes for road resurfacing and repair. The project involved 500 linear feet of bank correction and new construction.
Investigation on the influence of inlet conditions on the scour phenomenonCédric Bellet
Presentation of the conclusions of a research internship at TUM carried out in 2010.
The scour phenomenon is the fact that around marine structures embedded into the sediment bed, vortices are created which "scour", that is, erode the sediment bed and thus make the structure vulnerable. This study shows that experiments and empirical formulas produced by different researchers around the world show biases linked to their different experimental settings, relatively to the water inlet conditions.

2. Consider the linear function y = 1 − 2x. Find the inverse function, then compute the
derivatives of both functions. What do you notice?
3. The relationship in the previous problem works for any differentiable function with an
inverse. If f is differentiable at a point x0, then the derivative of f
−1 at an appropriate
point should be 1/f ′(x0), if f
′(x0) 6= 0.
(a) Sketch the graph of y =
√
x− 1, then find and carefully sketch its inverse on the
same graph.
(b) Find the tangent line to the graph of y =
√
x− 1 at the point where x = 5.
Sketch the tangent line on your curve.
(c) What is the corresponding tangent line on the graph of the inverse function?
What is its slope? You should be able to get this just by thinking about the
geometry.
(d) Compute the derivative of the inverse function directly. What input value must
you plug-in to get 1/y′(5)? (This is the slope you should have found in the previous
part.)
4. The previous problem illustrates the following result: If f is differentiable and has an
inverse on some interval I, and x0 is a point in I such that f
′(x0) 6= 0, then f−1 is
differentiable at y0 = f(x0), and
(f−1)′(y0) =
1
f ′(x0)
.
Use this to determine (f−1)′(3) for the function f(x) = x3 + x + 1, without finding the
inverse first.

Long Branch Tributary at Long Branch Falls ParkFairfax County
The Long Branch Tributary at Long Branch Falls Park project restored approximately 670 linear feet of stream within the Accotink Creek watershed. The stream channel was enhanced and stabilized using natural channel design elements. Existing erosion damage was repaired and future water quality has been improved. The project included channel realignment, in-stream rock structures, log structures, constructed wetlands, wood habitat clusters, deer exclusion fence, removal of invasive plants and the re-establishment of the riparian buffer with native species.
The Dead Run Drive Outfall Restoration project was substantially completed on August 27, 2018. The primary goals of this project were to address public safety concerns, stabilize an eroded channel by using natural stream design techniques, promote the growth of native vegetation and improve water quality. The natural channel design techniques used, such as a reinforced bed mix riffle sections and step pools, reduce the flow velocity, provide stability, and enhance water quality along the streams leading to the Chesapeake Bay. The disturbed areas of the site were restored with native shrubs, plants and trees.

Lower Hatchie National Wildlife Refuge Burlison, Tennessee
During the summer of 2014, the U.S. Department of Transportation, Federal Highway
Administration let a contract to remedy an area of significant bank erosion along the Hatchie
River in southwest Tennessee. The bank failure threatened an interior road within the Lower
Hatchie National Wildlife refuge. The goal was to stabilize the bank and construct a cellular
confinement system wall to prevent future erosion. The project included 500 linear feet of bank
correction and new construction. The contractor awarded the project, contacted Arc Surveying
and Mapping to perform existing conditions survey, construction layout, and quantity surveys.
Arc Surveying and Mapping performed an existing condition survey of the area using Trimble
Robotic Total stations and Trimble RTK GPS to collect data within our established horizontal and
vertical control network. This survey would serve as the “baseline” for all future quantity
calculations. In addition, Arc provided line and grade layout for the bank grading, geo-grid
stabilization, coffer dams, and new cellular wall. Finally, Arc provided grade stakes along the
existing road for re-surfacing and repair.
