%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 14. 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
(1999, ISBN:0 948540 94 X). "Flood Estimation Handbook Supplementary
Report No. 1", Kjeldsen (2007, ISBN:0 903741 15 7). "Regional Frequency
Analysis - an approach based on L-moments", Hosking & Wallis (1997, ISBN:
978 0 521 01940 8). "Making better use of local data in flood frequency
estimation", Environment Agency (2017, ISBN: 978 1 84911 387 8). "Sampling
