abstract: >-
  R interface and control unit for the RAINDROP hydrodynamic planning
  tool: long-term simulation of blue-green infrastructure (swale-trench
  elements) driven by real climate series, plus two cost optimisers
  that find the cost-minimal design per allowed overflow frequency - a
  deterministic bisection-based coordinate descent whose search order
  is derived from the construction cost rates, and an
  assumption-free simultaneous search (penalised Nelder-Mead,
  differential evolution and Halton sampling) as cross-check. The
  proprietary calculation engine ("Regenwasserbewirtschaftung",
  (c) Tandler.com GmbH) is not part of this package; it is downloaded
  on demand from the companion repository kwb.raindrop.binaries.
  Developed within the project RAINDROP (Rainwater Drainage
  Optimization, GZ C300428), funded by the Austrian Federal Ministry
  of Agriculture, Forestry, Regions and Water Management.
