<p>An economic method and apparatus for ecologically safely removing silt, muck, and sand from a water bottom and for collecting the silt, muck, and sand without destroying the benthos therein into porous containers where the then contained mud and silt can be ecologically positioned where desired to enhance subaquatic environments. The apparatus includes a silt and mud collecting and transfer device that has no moving parts and uses low kinetic energy movement of large masses at low terminal velocity, thereby not endangering the benthos or the porous containers in the transfer process.</p> |
