channel-floodplain Explanation: Several articles discuss submerged and unsubmerged surfaces. The submerged (flooded) surfaces are 'molhadas'. ... the combination of rough walls and a smooth bed. One test, a combination of smooth walls and a rough bed, gave an effective n value about 4 percent lower than measured. (4) James and Brown reported that the “Manning or Chezy equations do not accurately predict the stage discharge relation in a channel-floodplain configuration for shallow depths on the floodplain (1.0 < Y/D < 1.4; * where Y = main channel depth and D = main channel bank full depth) without adjustments to either the resistance coefficient or the hydraulic radius.... the effects of geometry seem to disappear at the higher stages, i.e., for Y/D > 1.4, it no longer became necessary to make any correction to the basic equations” (James and Brown 1977, p 24).
