LLUVIA: A program for one-dimensional, steady-state flow through partially saturated porous media

Creators

Description

LLUVIA is a program designed for the efficient solution of one- dimensional, steady flow through multiple layers of saturated or partially saturated, fractured, porous media. The original intent of the code was to provide initial pressure conditions to two- dimensional, finite element codes. LLUVIA's capabilities were expanded to meet the needs of analyses in the performance assessment of a proposed, high-level nuclear waste repository. The code is based on an adaptive solution method for Darcy's equation and is structured to accommodate user-defined models for hydraulic conductivity and saturation. Program structure, code input, and output are intended to facilitate the interfacing of LLUVIA with graphical and/or statistical software packages. This document describes the flow problem of interest, the solution procedure employed, and the content and content and format of all user-supplied information. A sample problem is also included. 8 refs., 13 figs
