environmentaltools.processes.sediment_transport_CERC

environmentaltools.processes.sediment_transport_CERC(data, params, theta_c)[source]

Calculate longshore sediment transport using CERC formula.

The CERC (Coastal Engineering Research Center) formula is used to estimate longshore sediment transport rates based on breaking wave characteristics.

Parameters:

data (pd.DataFrame) –
DataFrame with wave parameters including:
- Hr : Breaking wave height (m)
- thetar : Breaking wave angle (degrees)
params (dict) –
Dictionary with sediment and water properties:
- d50float
  Mean sediment grain size (m)
- rhofloat
  Fresh-water density (kg/m³)
- rho_sfloat
  Sediment density (kg/m³)
- nfloat
  Porosity
- gammafloat
  Breaking parameter
theta_c (float) – Beach angle (degrees)

Returns:
