Welcome Hec-Ras 5.0.4

 

  • Thanks USACE: a helpful step in a good direction for Catchment Process Analysis
  • Open source code: just add lidar & rainfall to quantify FRM opportunity
  • Not least, Atrepo’s 1000 km2 Upper Severn project (below) is more responsive: ‘5.0.4’  enhances sub-catchment approach to spatially variable rain-on-2Dmesh

In the meantime, also :

  • improved slope transfer across cells
  • more versatile 2D to 2D connection
  • Defra benchmarking
  • effective macro-opportunity-mapping by roughness control

  • So roll on 2019 and 5.0.5  (c/w  moving storm across whole catchment 2D area)
