LEVEEMSU: A Software Package Designed for Levee Underseepage Analysis.

摘要

This report describes the development, testing, and use of a software package named LEVEEMSU which was specifically designed for levee underseepage analyses. As such, it provides certain advantages for such analyses not afforded by either conventional hand analysis or general-purpose seepage analysis programs. Using the finite-difference method and microcomputer hardware, equations and assumptions used in conventional levee underseepage analysis are extended to levee cross-sections having irregular geometry, variable permeability, and/or variable landside water levels. Thus, the program provides a capability to analyze the effects of ditches, borrow pits, sloping ground, and other irregularities in a manner consistent with current and traditional analysis procedures for uniform cross-sections. A number of parametric studies and prototype reach analyses are provided to demonstrate the capabilities of the program.
