Tidal fluctuations and wave action can cause major damage to coastlines and off-shore construction projects. Nonwoven and specialty woven geotextiles can be used as a filter under layer beneath stone/ rock armour. Also riprap or synthetic erosion control mats are used to control erosion by disallowing the sub grade soil particles to erode. The geotextiles prevent erosion carried off by runoff water or other erosive waters, such as waves, stream flow, etc.

The largest threat to wetlands is the risk of being flooded with sediment as a result of a poorly managed construction site. Most construction projects require erosion control to prevent damage to the wetlands.
Problem: Soil particles are susceptible to being detached and carried away with concentrated runoff streams, forming rills and gullies that grow with time. The slope integrity is diminished, eroding the slope face and becoming a larger environmental and safety issue. Slopes steeper than the natural angle of repose for the slope materials require additional protection measures, as are slopes subject to more severe hydraulic stresses.

REMEDIAL ACTION PRACTICES include the requirements to develop erosion and sedimentation control plans, specifying plan content and soil conservation measures to keep sediment–laden mud from washing into storm sewers and watersheds where debris can clog creek channels and choke off aquatic life. Sediment control BMPs combine structural and non–structural measures used to avoid or minimize pollutants accumulated by environmental hazards across impervious surfaces.
Nilex’s engineered erosion control and sediment control products reduce the damaging effects of rainfall, wind and wave action on soil structures while replacing or reducing the dependency on scarce natural resources.
Geosynthetic erosion control products are designed to reduce damaging effects of rainfall, run-off, and wave and wind action on soil structures by redirecting water flow or acting as a barrier between the soil surface and water.
Nilex Erosion Control systems include: Erosion Control Blankets (ECBs); Turf Reinforcement Mats(TRMs); Gabion systems; Concrete Revetment and Mattresses; and Cellular Confinementsystems.
Properly implemented sediment control practices can result in minimal soil loss, little damage to
off-site receiving channels, enhanced project aesthetics and fewer complaints from regulators and the public.
Nilex Sediment Control systems include: GeoRidge Bio; Silt Fence; Turbidity Curtains;SedimentSTOP and Wattles; and Water Inflated Dams.

Coastal erosion is the wearing away of land or the removal of beach or dune sediments by wave action, tidal currents, wave currents, or drainage. Removing sand and other materials from beaches and dunes due to tidal storm surges and construction purposes causes massive beach erosion damages and land loss of seashores, thus destroying the natural heritage of the coast and reducing the vibrancy of the tourism industry. Uprooting vegetation from coastal areas destabilises beaches and clearing sites inland results in increased soil and dirt particles being washed offshore and smothering coral reef systems.
`Water should never be treated as a nonrenewable resource; it should always be treated with the respect it deserves as the foundation of life on the planet.` Most water on earth is in a continuous cycle between water bodies, land and the atmosphere. An important component of smart water solutions is the cycling of water treatment solutions using processes by which water enters, moves through and exits soil are essential for sustaining plants and soil organisms, transporting nutrients and recharging surface and ground water supplies. Water moving in soil also impacts the behavior and transport of soil solutes and their effect on water quality.
Turbidity is a measure of the loss of light transmittance through a liquid due to suspended particles. The more particles in the water, the murkier it looks or the higher the turbidity. This is a measure of the quality of the water. It is measured in units called Nephelometric Turbidity Units (NTU). Turbidity can be caused by run off after a heavy rain as erosion washes soil into a river or lake. It is often increased in the spring and fall when the water temperature at different levels in a lake change causing a turnover of those levels, bringing sediment, plants, and algae to the top.
