Version 2.0.0 beta

Release notes written by F. M^cNab

• Includes example network simulations with animations.
• Makes various additions/adjustments to the construction of random networks:
  • Adjust construction to align with new network structure/set up introduced in v2.0.0-alpha.
  • Support generation of random segment lengths and areas.
  • Support specification of network topology, segment lengths and/or segment areas.
  • Support along stream supply of sediment and water.
  • Support rescaling of the network to a given maximum length.
  • Support variable width, set to increase at the same rate as water discharge.
• Corrects some bugs in finite difference calculations introduced in v2.0.0-alpha:
  • z values on the RHS of the matrix equation should be filled with values from the previous time step. However, in the new structure, z was updated at each iteration, so that the non-linearity was not properly accounted for and the network evolved faster than it should by a factor of niter. The RHS is now filled with zold, avoiding the problem.
  • C1 was computed as a sum over upstream segments, doubling its effect. Corrected to mean.
• Supports change in water discharge over tributary junctions. Achieved with dQ_up_jcn, which needs to be set for each segment.
• Removes dependence of S0 on intermittency (I). Intermittency should not influence the slope, just scale the rate of change.
• Makes various additions/adjustments to the computation of network properties:
  • Compute network mean discharges, slope, and diffusivity.
  • Compute Tokunaga's matrices and metrics.
  • Compute properties associated with topological lengths and widths, including Jarvis's E.
• Adjusts planform plotting to align with new network structure and allow for variable segment lengths.
• Adjusts calculations of gain and lag to align with new network structure. Also, to avoid cycle skipping effects introduced at the inlet, assume lag should be small (< 0.5*period) at the inlet.
• Supports non-uniform dx at network mouth.
• Deprecates some out-of-date functions.
