Excerpt from Development of the Profile of Equilibrium of the Subaqueous Shore Terrace

The profile of a shore as seen at any one time is a compro mise between two forms. One Of these is the form which it possessed when the water assumed its present level; from this form it is continually departing. The other is the form which the water is striving to give to it; toward this form it is continu ally tending. There is a profile of equilibrium which the water would ultimately impart, if allowed to carry its work to comple tion. The continual change of shore line and the supply Of new drift are everchanging conditions with which no fixed form can be in equilibrium. There are, however, certain adjustments of current, slope and load which, when once attained, are maintained with some constancy. The form involved in these adjustments is commonly known as the profile When this pro file has once been assumed the entire form may slowly shift its position toward or from the land, but its slope will change little or not at all. It may be compared to a stream Channel which has reached grade but not base level.
