A detailed description of OS LISFLOOD standard and optional modules is available from the Model Documentation
The reservoir modelling routine was updated with OS LISFLOOD v5: the updated methodology is described in this page. Former versions of OS LISFLOOD code required the following parameters for reservoir modelling: | ParameterName | MinValue | MaxValue | DefaultValue | | :—————————– | —————–: | —————–: | —————–: | | adjust_Normal_Flood | 0.01 | 0.99 | 0.8 | | ReservoirRnormqMult | 0.25 | 2 | 1 |
