Not All Flood-Lines Are Equal (Part 2)
In the previous post (Part 1), the discussion centered around flood hydrology, which is one of two primary components in the simulation (or modelling) of flooding and resulting definition of flood-lines. The terms accuracy and detail as they relate to flood modelling...
Not All Flood-Lines Are Equal (Part 1)
In South Africa, we term the boundary or maximum extent of simulated (or modelled) flooding, flood-lines, which is a common output from a computer model of simulated flooding (or flood model for short). Flood-lines usually relate to a recurrence...
Why flood-lines (floodlines or flood lines)
At Hydrologic we keenly pursue the latest developments in flood-line modelling that are sure to result in a more accurate, legible and sensible flooding assessment. Our ability to produce quality work comes from a solid foundation in flood risk that was gained in...
