This report includes a description of a set of topographic contouring computer programs which are operational on DOS-based personal computers, including a discussion of the mathematical procedure used to generate the contour maps and a detailed User's Guide.

Computer program "McCON" used for creating topographic contour maps.

This report describes a research study in which techniques were developed for prediction of underseepage conditions for special cases of levee and foundation geometry. The differential equations for levee underseepage were derived and programmed in finite difference form for three special cases of boundary conditions. The developed programs allow analyses that are not restricted to the boundary conditions assumed in the conventional, closed form solution, i.e., two foundation layers of uniform thickness with horizontal boundaries.

Report discussing the FORTRAN 77 computer program (LEVSEEP), developed to analyze levee underseepage on IBM PC compatible microcomputers with an 8087 math coprocessor. The software and associated equipment plots cross sections and piezometer data; calculates seepage flow and substratum pressure; analyzes landside berm, river side blanket, cutoff and relief well control measures; and finally, estimates the construction cost of these alternatives.

Abstract: "A set of 12 charts are presented that relate Modified Mercalli intensity units to peak horizontal acceleration, velocity and duration for near field and far field locations, hard and soft sites, and sizes of earthquakes. Also shown is the mean, mean plus one standard deviation, mean plus two standard deviations, and the highest observed values. Ratios are provided of vertical to horizontal motions and predominant periods. These charts are for use with known fault sources and for floating earthquakes in zones where there are no identifiable causative faults. The procedure provides parameters for shaping time histories to be used for dynamic analyses."

"This is one in a series of scientific reports documenting the findings of studies conducted under the Interagency Field Verifications of Testing and Predictive Methodologies for Dredged Material Disposal Alternatives (referred to at the Field Verification Program or FVP). This program is a comprehensive evaluation of environmental effects of dredged material disposal under conditions of upland and aquatic disposal and wetland creation."
