Summary Contact Technical specs In/Output Process Testing Other Component info Also known as Gravel River Long Profile Model type Single Model part of larger framework Note on status model Date note status model Incorporated models or components: Spatial dimensions 1D, 1.5D Spatial extent Continental, Regional-Scale, Landscape-Scale, Watershed-Scale, Reach-Scale, Patch-Scale Model domain Terrestrial One-line model description Evolves gravel-bed river long profiles Extended model description Computes transient (semi-implicit numerical) and steady-state (analytical and numerical) solutions for the long-profile evolution of transport-limited gravel-bed rivers. Such rivers are assumed to have an equilibrium width (following Parker, 1978), experience flow resistance that is proportional to grain size, evolve primarily in response to a single dominant "channel-forming" or "geomorphically-effective" discharge (see Blom et al., 2017, for a recent study and justification of this assumption and how it can be applied), and transport gravel following the Meyer-Peter and Müller (1948) equation. This combination of variables results in a stream-power-like relationship for bed-material sediment discharge, which is then inserted into a valley-resolving Exner equation to compute long-profile evolution.
