Depth of Closure given Volume per unit Length of Shoreline Solution

STEP 0: Pre-Calculation Summary

Formula Used

Depth of Closure = ((Volume per unit Length of Shoreline/Beach Width)-Design Berm Elevation)
D_c = ((V/W)-B)
This formula uses 4 Variables

Variables Used

Depth of Closure - (Measured in Meter) - Depth of Closure for a characteristic time interval is the most landward depth seaward of which there is no significant change in bottom elevation.
Volume per unit Length of Shoreline - (Measured in Square Meter) - Volume per unit Length of Shoreline is the volume of sediment contained within a cross-sectional area of the beach, per unit length along the shoreline.
Beach Width - (Measured in Meter) - Beach Width is the horizontal distance from the shoreline to a specific point inland which can vary greatly depending on factors such as tide, season, and human intervention.
Design Berm Elevation - (Measured in Meter) - Design Berm Elevation is a level space, shelf, or raised barrier (usually made of compacted soil) separating areas vertically, especially part-way up a long slope.

STEP 1: Convert Input(s) to Base Unit

Volume per unit Length of Shoreline: 255 Square Meter --> 255 Square Meter No Conversion Required
Beach Width: 30 Meter --> 30 Meter No Conversion Required
Design Berm Elevation: 2.5 Meter --> 2.5 Meter No Conversion Required

STEP 2: Evaluate Formula

Substituting Input Values in Formula

D_c = ((V/W)-B) --> ((255/30)-2.5)

Evaluating ... ...

D_c = 6

STEP 3: Convert Result to Output's Unit

6 Meter --> No Conversion Required

FINAL ANSWER

6 Meter <-- Depth of Closure

Depth of Closure given Volume of Sand per unit Length of Shoreline

Go Depth of Closure = Parameter for Fill Sands*(Volume per unit Length of Shoreline/((3/5)*(Parameter for Native Sands-Parameter for Fill Sands)))^(2/5)

Volume of Sand per unit Length of Shoreline placed before there is any Dry Beach after Equilibrium

Go Volume per unit Length of Shoreline = (3/5)*(Depth of Closure/Parameter for Fill Sands)^(5/2)*(Parameter for Native Sands-Parameter for Fill Sands)

Design Berm Elevation given Volume per unit Length of Shoreline

Go Design Berm Elevation = ((Volume per unit Length of Shoreline/Beach Width)-Depth of Closure)

Depth of Closure given Volume per unit Length of Shoreline

Go Depth of Closure = ((Volume per unit Length of Shoreline/Beach Width)-Design Berm Elevation)

Volume per unit Length of Shoreline required to produce Beach Width

Go Volume per unit Length of Shoreline = Beach Width*(Design Berm Elevation+Depth of Closure)

Active Sediment Volume given Seawall Trap Ratio

Go Active Sediment Volume = Wall Trap Volume/Seawall Trap Ratio

Wall Trap Volume given Seawall Trap Ratio

Go Wall Trap Volume = Seawall Trap Ratio*Active Sediment Volume

Seawall Trap Ratio

Go Seawall Trap Ratio = Wall Trap Volume/Active Sediment Volume

Depth of Closure given Volume per unit Length of Shoreline Formula

Depth of Closure = ((Volume per unit Length of Shoreline/Beach Width)-Design Berm Elevation)
D_c = ((V/W)-B)

What is a Berm and purpose of Berm?

A berm is a level space, shelf, or raised barrier (usually made of compacted soil) separating areas vertically, especially part-way up a long slope.
Berms prevent off-site sedimentation by diverting runoff to a sediment-trapping device and can also be used to divert clean water from entering a disturbed area. They can also trap sediment by ponding and settling out sheet flow runoff, or by filtering sediment as runoff passes through permeable berms.

What is the Depth of Closure?

The depth of closure for a given or characteristic time interval is the most landward depth seaward of which there is no significant change in bottom elevation and no significant net sediment exchange between the nearshore and the offshore.

How to Calculate Depth of Closure given Volume per unit Length of Shoreline?

Depth of Closure given Volume per unit Length of Shoreline calculator uses Depth of Closure = ((Volume per unit Length of Shoreline/Beach Width)-Design Berm Elevation) to calculate the Depth of Closure, The Depth of Closure given Volume per unit Length of Shoreline formula is defined as the distance offshore where wave action no longer impacts sediment transport, determined by volume per unit shoreline length. Depth of Closure is denoted by D_c symbol.
