==Notes==
*Presents evidence supporting an "alternate stable state" hypothesis driven by the introduction of large stable log jams which depend on large key pieces of wood.
*Absence of key pieces results in rapid turnover of floodplain surfaces (see [[Naiman et al 2009]]) which prevents production of key pieces (a reinforcing feedback loop).
*Presence of key pieces allows for formation of floodplain islands, which reduces the rate of surface turnover, allowing for production of more keypieces (also a reinforcing feedback loop).
*The presence or absence of key pieces and associated hard points can result in a shift in state from an anastomosing structure, or a braided or meandering structure (depending on factors such as slope and sediment budget.)
*Under this theory, construction of [[Engineered Log Jams]] is in part a temporary reestablishment of hardpoints within a floodplain to push the river from one state to another state .
**What is the lifespan of an ELJ and does that match the necessary function of a floodplain hard point?
