The purpose of this paper is to present the general topic of lake processes to an engineering audience from a geological point of view. It is apparent that the shores of larger lakes present many problems in common with the sea coast, but the absence

Beaches along Lake Michigan display a wide range in texture and composition. Some are composed of fairly uniform sand or gravel, others display an irregular mixture of both. Host beach sand is predominantly quartz with variable amounts of calcite, fe

Enclosure of some portion of one or more natural stream-drainage basins by superposition of a rectangle on a map of drainage network results in fragmentation of the natural basins into a set of disjoint channel networks. Each of these may have some c

It is generally agreed that particle size distributions of sediments tend ideally to approximate the form of the lognormal probability law, but there is no single widely accepted explanation of how sedimentary processes generate the form of this law.

Three models that specify allowable branching events during the growth of stream channel networks through time are introduced. These models identify the possible topologie "growth paths" that may be followed as a network grows from a single link to o

Pebbles from glacial till, from an outwash terrace, and from a beach show characteristic preferred orientations. Methods used in collecting and measuring the pebbles are described, and the importance of two distinct concepts in orientation analysis i

It is well known among geologists that closure of an open-number system, as when stratigraphic rock thicknesses are converted to percentages, introduces correlations among the components even in the absence of correlations in the open system. In clos
