The Problem
		Riverbed rising: too much sediment being deposited near New Orleans, exacerbating flood risk, not enough in wetlands. Wetlands: not receiving enough sediment.  River used to deposit sediment to build up wetlands, both continually and during floods.  Now river empties over edge of continental shelf, and sediment is lost into the Gulf of Mexico. River flood risk: frequency of floods, precipitation pattern in drainage basin. Maintenance: preserving navigable channel, upkeep of armored banks and dams. Monitoring: placement of monitoring stations and improved communication between them; subsidence, sea level, water level, flow rate, sediment movement in relation to fault. Subsidence: compensating for subsidence with increased sediment deposition, take subsidence into account when calculating heights of levees and floodwalls. Take displacement of people into account for above solutions.
