visualization of morphology change in measured bathymetry

Recommended Posts

Dear

1.How can I visualize the morphology change for the measured bathymetry as I want to compare the measured one to the calculated?

and how to polygon to calculate volume change between both.

2. how to choose between sediment transport statistics( gross- net- total) if I want to make sensitivity analysis between sediment transport and Manning or d50?

What engine (numeric model) are you using?

What is the format of the "measured" change in bathymetry? Do you have it at multiple locations, a full survey, or just a few points?

1.I am using CMS software( CMS-FLOW) and (CMS-WAVE) .

2. A full survey( I have the measured bathymetry at the end of my simulation to compare with) but I not do know how it works

CMS-Flow will output a final bathymetry (z) value for each cell in the grid.

If you read in the full survey of final measured bathymetry as a scatter point set (TIN) in the scatter module, you can interpolate that to the grid.

Then you use the data calculator or the compare function in the dataset tool box (Data menu) to create a difference dataset.
