Description | COVAR is a program for generating 2D fields of autocorrelated parameters which are normally or log-normally distributed (eg hydraulic conductivity). The program uses a technique based on (Choleski) matrix decomposition. The generated parameter field represents a major requirement in the stochastic analysis via Monte-Carlo techniques. The program requires as input a list of x,y coordinates for which the parameters need to be generated, and statistical parameters describing the distribution of the hydrologic parameter of interest. The program facilitates a maximum of 20x20 nodes. For larger problems, the program can be modified and recompiled. The program can also be modified to be used as a subroutine in a Monte Carlo type 2D stochastic flow or mass transport model. Program data input is interactive. Output is a text file with tabular results. |
