netsse.tools.envir_cond.lin_disprel
===================================

.. py:function:: netsse.tools.envir_cond.lin_disprel(omega, h)

   Computes the wavenumbers from wave angular frequencies in finite water depth.

   This function implements a fast and accurate approximation of the linear wave
   dispersion relationship in finite water depth.

   :param omega: Wave angular frequencies [rad/s].
   :type omega: array_like or float
   :param h: Mean water depth [m]
   :type h: float

   :returns: **k** -- Wavenumbers [1/m]
   :rtype: array_like or float

   .. rubric:: Example

   >>> k = lin_disprel(omega,h)
