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