The Channels tab is used to input variables that GeoFluv™ will use to design channel geometry dimensions (including radius of curvature, meander length, meander belt width, sinuosity, and channel cross sections that are sized for bankfull and more extreme flood events), to add or delete channels from the design, to name channels, to view channel longitudinal profiles, and to design related upland landforms, and to generate reach-scale reports of the design characteristics of channels.
GeoFluv™’s draft design will have concave longitudinal channel profiles that join together in a smooth hydraulic transition. GeoFluv™ will automatically design drainage-divide ridges between the channels that form subwatersheds for each channel using this information. GeoFluv™ will also automatically design the sub-ridges and sub-ridge valleys in each subwatershed, and calculate and display the subwatershed area, subwatershed channel valley length, and subwatershed drainage density.
