The objective is to return streams that have been modified back to their natural state. The stream is allowed to meander and bends area stabilized with large stones known as riprap. These include both earthen and concrete levees, floodways, and storm-water retention basins. Breaks in levees can cause high energy flows of water that quickly inundate an area. The impermeability of the soil causes excess water to accumulate on the surface instead of infiltrating. The land in the north has been slowly rising since the disappearance of an ice sheet 5000 years ago; this causes a very slow river current because there is little difference in elevation between the south and north. All of these factors contribute to consistent flooding along the red river in. Manitoba and north dakota: urban growth rates (2010-2015), mdw: approx. 1% or < 1% (canada 1. 2%, us 1 %, western.
