Abstract
We consider a flap-gate farm, i.e. a series of P arrays, each made by Q neighboring flap gates, in an infinitely
long channel. We show that there are P × (Q − 1) natural modes and determine their eigenfrequencies
and modal forms. When the distance between the arrays goes to infinity the eigenfrequencies converge to
the Q − 1 values given by Li and Mei [14]. For an ad-hoc combination of channel geometry and flap gate
characteristics, modal excitation can give significantly larger response than for the case of a single or a sparse
gate system. This aspect is relevant for the design of an optimal gate farm wave energy converter
