Valley or stream erosion occurs with continued water flow along a linear feature. The erosion is both downward, deepening the valley, and headward, extending the valley into the hillside, creating head cuts and steep banks. In the earliest stage of stream erosion, the erosive activity is dominantly vertical, the valleys have a typical V cross-section and the stream gradient is relatively steep. When some base level is reached, the erosive activity switches to lateral erosion, which widens the valley floor and creates a narrow floodplain. The stream gradient becomes nearly flat, and lateral deposition of sediments becomes important as the stream meanders across the valley floor. In all stages of stream erosion, by far the most erosion occurs during times of flood, when more and faster-moving water is available to carry a larger sediment load. In such processes, it is not the water alone that erodes: suspended abrasive particles, pebbles and boulders can also act erosively as they traverse a surface, in a process known as traction.

The Power of Rain – Impact Minimization

This popular annual event brings together professionals from Wisconsin, Minnesota and other Midwest states to learn about the latest in stormwater and erosion control in the classroom. Morning classroom presentations may include: Wisconsin standards for water and land applied polymers; Wisconsin BMP Standards vs Minnesota BMPs Standards; St. Croix Bridge
