Also known as
Model type Single
Model part of larger framework
Note on status model
Date note status model
Incorporated models or components:
Spatial dimensions 1D
Spatial extent Reach-Scale
Model domain Terrestrial, Hydrology
One-line model description Ode To Transient (Ancho de los) Rivers: Transient evolution of river-channel width in response to river discharge and bank and sediment properties.
Extended model description Transiently evolving river-channel width as a function of streambank properties, sediment in transport, and the hydrograph.

This model is designed to compute the rates of river-channel widening and narrowing based on changing hydrological regimes. It is currently designed for rivers with cohesive banks, with a critical shear stress for particle detachment and an erosion-rate coefficient.

OTTAR contains:

  • The RiverWidth class, which contains methods to evolve the width of an alluvial river.
  • The FlowDepthDoubleManning class, which is used to estimate flow depth from discharge, even with an evolving river-channel geometry.
