Introduction
In this tool (breakwater design) you can compute required dimensions, overtopping, cross-sections and costs of breakwaters.
The tool requires at least a breakwater and bathymetry data (you can inspect the generic data availability in the top panel of the tool).
Optionally, any generic wave data can also be used, in order to fill the wave condition fields.
Computations of breakwater dimensions and costs are based on rough guidelines in the rock manual.
Results of the breakwater tool should therefore be interpreted with a considerable range of uncertainty.
How to use the tool
- Open a new project
- Start in Generic Data by defining a
User input fields
A number of user input fields are provided which can be used to adjust the calculation according to the local situation. Default values are provided for each input field. The following inputs are defined:
Generic computation settings
Design storm conditions
Armouring
Reduction factors
Unit cost price
Tool limitations
The following processes are not included in the tool: waves approaching under an angle, bed level changes caused by wave reflection etc. Besides, the tool only provides linear cross-sections comprising of 3 default materials, without providing information on the breakwater toe or round heads. Results of the breakwater tool should therefore be interpreted with a considerable range of uncertainty.
Example cases
The following files (.dsproject) can be downloaded and loaded into CoDeS to serve as examples. They are not based on actual projects, but are intended as illustration.
Unzip the files to an convient folder (but make sure the file structure does not change), and open the .dsproject file from within CoDeS.
