Using a submersible pump is an efficient DIY method for dredging ponds under 1 acre in size.. Gas or electric-powered pumps fitted with suction hoses can vacuum sediment from the bottom much like a wet/dry shop vac. Feed the discharge hose to an area away from the pond to deposit the slurry of water and sediment.

Granulometry of sediments is an important parameter as it decides the sediment's suitability for crude bricks. Granulometry of Dunkirk (DK) and Usumacinta River sediments (USU) was found with laser granulometry according to French recommendations (AFNOR NF X31-107, 2003).The silt, sand, clay content and medium diameter of both …

Dredging removes extra muck and mud from bodies of water. The dredge uses a submersible pump that sucks up debris and a tube that transports the sediment from where it rests in the water to the surface. To properly dispose of the dredged material, you will need to follow local, state and federal laws and regulations.
