Go Hoerls Special Function Distribution = Hoerls Best-fit Coefficient a*(Filling Index^Hoerls Best-fit Coefficient b)*e^(Hoerls Best-fit Coefficient c*Filling Index)

Density of Water given Water Surface Slope

Go Density of Water = (Coefficient Eckman*Shear Stress at the Water Surface)/(Water Surface Slope*[g]*Eckman Constant Depth)

Water Surface Slope

Go Water Surface Slope = (Coefficient Eckman*Shear Stress at the Water Surface)/(Density of Water*[g]*Eckman Constant Depth)

Shear Stress at Water Surface given Water Surface Slope

Go Shear Stress at the Water Surface = (Water Surface Slope*Density of Water*[g]*Eckman Constant Depth)/Coefficient Eckman

Coefficient given Water Surface Slope by Eckman

Go Coefficient Eckman = (Water Surface Slope*Density of Water*[g]*Eckman Constant Depth)/Shear Stress at the Water Surface

Ratio of Depth of Channel to Depth at which Seaward Slope of Ocean Bar Meets Sea Bottom

Go Depth Ratio = (Depth of Navigation Channel-Natural Depth of Ocean Bar)/(Water Depth between Sea Tip and Offshore Bottom-Natural Depth of Ocean Bar)

Water Depth where Seaward Tip of Ocean Bar meets Offshore Sea Bottom

Go Water Depth between Sea Tip and Offshore Bottom = ((Depth of Navigation Channel-Natural Depth of Ocean Bar)/Depth Ratio)+Natural Depth of Ocean Bar

Depth of Navigation Channel given Depth of Channel to depth at which Ocean Bar meets Sea Bottom

What is Ocean Dynamics?

The Ocean Dynamics define and describe the motion of water within the oceans. Ocean temperature and motion fields can be separated into three distinct layers: mixed (surface) layer, upper ocean (above the thermocline), and deep ocean. Ocean dynamics has traditionally been investigated by sampling from instruments in situ.

What is Dredging?

Dredging is the act of removing silt and other material from the bottom of bodies of water. It is a routine necessity in waterways around the world because sedimentation—the natural process of sand and silt washing downstream—gradually fills channels and harbors.
