Profile Type
Defines the interpolation method you want CAESAR II to use to determine the current velocity as a function of depth. Available options for this entry are:
-
Power Law Profile
Determines the current velocity at depth D according to the equation:
Vd = Vs * [di / D]p
Where:
Vd - is the velocity at depth di
Vs - is the specified velocity at the surface
D - is the water depth
p - is the power, set to 1/7
-
Piece-wise Linear Profile
Performs a linear interpolation of a velocity verse depth table that you must provide, to determine the current velocity at depth di. The table should start at the surface (a depth of zero) and progress in increasing depth to the sea bed.
-
Linear Profile
Performs a linear interpolation to determine the current velocity at depth di. However, this method assumes the current velocity varies linearly from the specified surface velocity to zero at the sea bed.
-
Current Speed
Defines the current speed at the surface. The units for this entry are (length/time) as defined by the active units file at the time of input. This value should always be a positive entry.
-
Current Direction Cosines
Defines the direction of fluid transport due to the current. These fields are unit-less and follow the standard software global axis convention.
