Dredging Permitting in the USA

Dredging Permits FAQs

Major effort and planning is required to get the permits for your dredging project. Any errors on the permit documents can require time for corrections that will delay your project.

Submersible Pump for Dewatering

Pump FAQS

Pumps transfer liquids from one point to another by converting mechanical energy from rotation into pressure energy (head)The pressure applied to the liquid forces the fluid to flow at the required rate and to overcome friction (or head) losses in piping, valves, fittings, and process equipment.
Pump Terminology

Pump Terminology

The pump provides the energy necessary to drive the fluid through the system and overcome friction and any elevation difference. Pressure is increased when fluid particles are forced closer together.

History of Dredging

History of Dredging

Water has always been a key way to transport people, goods, and everything else. Yet it’s not always smooth sailing.

Sediments Suspended Load Movement

Sediment and Suspended Sediments

Storms significantly influence rivers by increasing the water flow and its speed, as well as the amount of sediment. Just one storm can bring half of the sediment moved in a year.

Pump Characteristics

Pump Characteristics

Pressure, friction and flow are three important characteristics of a pump system. Pressure is the driving force responsible for the movement of the fluid. Friction is the force that slows down fluid particles. Flow rate is the amount of volume that is displaced per unit time.
