%description
Functions to implement the methods of the Flood Estimation Handbook (FEH),
associated updates and the revitalised flood hydrograph model (ReFH).
Currently the package uses NRFA peak flow dataset version 12.1. Aside from
FEH functionality, further hydrological functions are available. Most of
the methods implemented in this package are described in one or more of
the following: "Flood Estimation Handbook", Centre for Ecology & Hydrology
