- Abstract
- The stochastic Lagrange wave model is a realistic alternative to
the Gaussian linear wave model, which has been successfully used
in ocean engineering for more than half a century. This paper
presents exact slope distributions and other characteristic
distributions at level crossings for symmetric and asymmetric
Lagrange space and time waves. These distributions are given
as expectations in a multivariate normal distribution,
and they have to be evaluated by simulation or numerical integration.
Interesting characteristic variables are: slopes obtained by
asynchronous sampling in space or time, slopes in space or time,
and horizontal particle... (More) - The stochastic Lagrange wave model is a realistic alternative to

the water level crosses a predetermined level. (Less)
