Bug fixes and updates for release 2020.1.2

• Wflow_sbm and wflow_hbv
  • Improved kinematic wave solution when iterating: now using states at sub-timestep. This change affects the simulated discharge (timing and peaks) quite a bit (compared to previous versions)
  • Changed self.reallength to self.xl and self.yl for cell area calculation, this is more precise for lat lon models
  • Small fixes for wflow_hbv (exporting riverwidth map and "pcr" (PCRaster) missing for accucapacitystate function (pcr.accucapacitystate))
• Fixes and updates for wflow_topoflex
• Fix glacier melt issue (could contain missing values)
• Fix issue with Numba versions > 0.48 (numba.errors moved to numba.core.errors)

Bug fix release for 2020.1

Resolved bug in reservoir\lake functionality in wflow_hbv.

2020.1

• Wflow_sbm

  • Improved soil evaporation and transpiration.
  • Vertical unsaturated flow (iterations now based on fixed maximum change in soil water per iteration step).
  • Interception before snow and glacier modules (total precipitation first intercepted), snow and glacier melt directy available for infiltration into the soil (no interception).
  • CFMAX snow parameter now model timestep independent (conversion).
  • Convergence criterium for the kinematic wave for subsurface flow changed (very large M model parameter values result in too many iterations).

• BMI

  • Removed RTC Tools 1.0 coupling.

• Reservoir module

  • Time step max 6 hr (as Lake module), solved completely explicit (no averaging between time steps),
    above spillway outflow 100%

• Lake module

  • Bug in variablename: changed ReserVoirComplexLocs to LakeLocs

• Glacier modelling

  • Updates in wflow_sbm.py and wflow_hbv.py
  • Added a new map containing glacier IDs: wflow_glacierareas.map.
  • Linking the glacier tbl properties (G_TT, G_Cfmax and G_SIfrac ) to the glacier IDs map.
  • Renaming the default names of the glacier maps to fit better the wflow schematization (wflow_glacierareas.map, wflow_glacierfrac.map and wflow_glacierstore.map).

• Wflow_emwaq

  • Better separation between the creation of the structure files and the dynamic files generated by the coupling (wflow_sbm doesn’t need to run anymore to generate structure files).
  • Possibility to add a Delwaq input file (.inp) from a template to the generated list of files.
  • Possibility to add extra timers file for statistics computation in Delwaq (block 10 of the input file).

• Wflow_sediment

  • General update of the script to match the updates of wflow_sbm since beginning of 2019.
  • Better separation of overland flow and river runoff using directly the input from wflow_sbm (RiverRunoff and LandRunoff instead of SurfaceRunoff).
  • Added new schematization maps for river characteristics that were also incorporated in wflow_sbm (RiverSlope, wflow_riverlength, wflow_riverwidth).
  • Added the possibility to iterate the river transport and processes equations.

2019.1

• Wflow_sbm, redesign of lateral subsurface flow because of a bug that resulted in an overestimation of lateral subsurface flux:

  • The kinematic wave approach is used to route subsurface flow laterally.
  • Kinematic wave solution for surface (overland and river) and subsurface flow added to wflow_funcs, and used by wflow_sbm.
    Numba (open-source JIT compiler) is used to accelerate these functions. This replaces the PCRaster kinematic wave solution.
  • A seperate kinematic wave reservoir for river (self.RiverRunoff) and overland flow (self.LandRunoff)
  • Lateral subsurface flow and overland flow feed into drainage network (channel) based on ratio slopes
    (slope upstream cell / (slope upstream cell + slope cell))
  • Option to provide land slope and river slope (staticmaps)
  • Removed sub-grid runoff generation
  • Removed re-infiltration of surface water

• Wflow_hbv uses kinematic wave solution for surface flow available in wflow_funcs (replacement of PCRaster kinematic wave solution)

• Option to enable iteration (smaller time steps) for kinematic wave solution for surface runoff (wflow_hbv and wflow_sbm)

• Added hydrological model wflow_w3 to wflow framework, based on Australian Water Resources Assessment Landscape model (AWRA-L),
  an improved version compared to wflow_W3RA.

• Added hydrological model wflow_stream to wflow framework (STREAM (Spatial Tools for River Basins and Environment and Analysis of Management Options)).

• Added experimental version of wflow_sediment to simulate soil erosion and delivery to the river system.

• Added the wflow_emwaq module: provides a set of functions to create and link a Delft3D-WAQ or D-Emission model to a wflow model.

• Update of lake modelling for wflow_hbv and wflow_sbm (including also Modified Puls Approach) in wflow_funcs

• Update of glacier model (used by wflow_hbv and wflow_sbm)

• Parameter Manning N of river can be linked to streamorder for wflow_hbv

• setuptools_scm used for version wflow package
