For a general overview of a variety of outlets, see "Design of flood storage reservoirs" by Hall, Hockin and Ellis, published by CIRIA (Book 14, reprinted 1996).

Multiple orifice control structures can be messy and hard to construct, does anyone have any design guidelines for keeping flow regimes to predevelopment conditions for a range of events (ie. 1yr, 5yr, 20 yr, 50 yr,100 yr recurrance interval pre to post). I was also wondering what other forms of outlets are available. Thanks Nigel Bosworth %%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%
