Chapter 34: Aggradational Landforms of Streams

The Edmonton River Valley



Like much of the world’s major streams, those of the Edmonton Larchlands are a part of a drainage system that will inevitably flow into the oceans as opposed to a closed basin. A loss in stream capacity during its latter course, without the presence of proper slope, brings an end to the degradation process and starts aggrading, setting up alluvial landforms.  The meanders seen in the picture are bends in the stream channel where erosion occurs, deposition happening on the inside of the meanders while erosion takes place on the outer sides.
