Fluvial Geomorphology on a Glacial Till Plain

Abstract

<p>Fluvial channel adjustment on a glaciated till plain in Southern Ontario is investigated. Mallot River, a component of the Grand River system is used as an example. Concepts of equilibrium and underfitness are discussed. Field studies include over thirty miles of longitudinal and transverse valley profiles. Laboratory investigation produced a detailed map from air photographs. It contains more than 15,000 First Order segments. Morphometric analyses were conducted using this base. A hierarchy of drainage density is suggested. A comparison with drainage on non-glaciated material concludes the study.</p>
