"Channel capacity also depends on the long-term trends in downstream floodplain land use. While it is not a hydrologic problem, channel capacity studies should recognize the impact of floodplain encroachments on what is considered the nondamaging channel capacity. Anecdotal history has shown that many Corps' projects are not able to make planned channel-capacity releases due to development and encroachment downstream."[1]
