متن کاملFlume experiments on the migration rate of wave - formed ripple marks
The migration rate of wave-formed ripple marks was investigated using a twodimensional wave flume. Well sorted fine-grained sand (0.2 mm in diameter) was placed on a 1/20-fixed slope and an adjacent part of the horizontal flume bottom. The onshore migration rates of ripples and near-bottom orbital velocities were measured at three sites along the slope with different water depths and at one sit...

The integration of a proof system and a programming language of industrial strength can be fairly useful in this respect, like in the case of, for instance, the B method [1] or the functional programming languages Erlang [12,5] and Clean [6,4].
