soil Erosion

Soil erosion is the denudation or wearing away of the upper layer of soil. It is a form of soil degradation.

Soil Erosion



The actual sampling of soil, air, groundwater and/or building materials.

Geotextile reinforced soil walls are technically interesting pollution solutions because test loads applied to geotextile reinforced soil walls and slopes have demonstrated that the actual failure load is far above what current design methodologies allow. Geotextile reinforced soil walls and slopes present not only a technically interesting solution for supported earth structures, but most important, an  economical alternative to rigid concrete walls or slopes. Compared to conventional graded granular soil filters, geotextiles offer advantages by providing:

  • A substantial reduction in material costs
  • Consistent and continuous filter
  • Reduced environmental impact
  • Reduced time of construction
  • Simplified, higher quality construction

Soft soil engineering offers geotechnical and remediation services across a national footprint including deep soft soils in the flood plain areas. Mass stabilisation, both Environmental and Infrastructure–based development is a ground improvement method for soft soil layers & for In Situ Remediation for Contaminated Sediment that provides an effective permeable, drought tolerant solution. Green remediation is the use of these best management practices to reduce the environmental footprint of actions designed to clean up contaminated media (soil, groundwater, etc.) and return impacted property to productive use.




 Sediment remediation generated by soil contamination is an environmental concern and may lead to the more serious problem of groundwater contamination. “Mitigating the effects of poor soil conditions once sediment has entered the drainage system and aquatic environment is difficult, expensive and labour–intensive.” Sediment capture devices should not be the primary line of protection against off site damage. Erosion prevention at the outset remains the best alternative. Sediment traps, basins, buffers, and barriers will retain sediment on site. Such collection devices need regular maintenance and removal of the accumulated sediment. A proportion of contaminated sites are Brownfield Redevelopment Sites. In severe cases, brownfield sites may be added to the National Priorities List where they will be subject to the U.S. Environmental Protection Agency’s Superfund program. New study by MIT ( Massachusetts Institute of Technology ) shows how nanoparticles can clean up environmental pollutants. Nanomaterials and UV light can trap chemicals for easy removal from soil and water.

REMEDIAL ACTION PLANS 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 resulting in sediment violations.

Enhanced bioremediation

As EPA regulations become more stringent, your handbook of erosion materials & stormwater controls would be remiss if it did not list a complete line of products for enhanced bioremediation that filter sediment thus preventing ’aggradation’ (raising of the rive) after pollution and soil loss. Erosion control may arise in natural areas, agricultural settings or urban environments, the latter of which is often characterized as stormwater runoff.

Highway engineering

Highway engineering encounters construction site pollution & toxic soils contaminated with materials, mostly chemicals, that are out of place or are present at concentrations higher than normal which may have adverse effects on humans or other accompanying organisms.

The landowner has the responsibility to oversee development of:

  1. Dredging of PCB–laden sediment
  2. Installation, maintenance, and inspection of all best management practices–BMPs.
  3. Providing overall environmental cleanup soil remediation services on a nationwide basis
  4. Site–specific erosion control plans
  5. Smart Construction

Best management practices ( BMPs ) combine structural and non–structural measures used to avoid or minimize pollutants accumulated by environmental hazards across impervious surfaces.

Hydraulic dredging projects involving fine grained sediment, as well as clays, silts, and organics are responsible for maintaining navigation. Quid pro quo : they probably thought of dredging. However, the prescribed work is actually removing shoals, or shallow spots that are created by sand banks or sand bars. Sediment (ocean) dumping, a practice that is detrimental to both environmental and flood control interests, affects both sediment on the Aquatic Environment and Actions to Improve Aquatic Habitat.

Sediment dumping (sic) should not be available to government entities like the Corps of Engineers who should be held to an equal or higher standard than private parties.

Heavily contaminated sediment and erosion can reduce the lifespan of dams and reservoirs, thus compromising the safety of people living nearby. Most influential to the rate of sediment movement is major flood events, which is responsible for causing significant land erosion. Most of this “dirt” is the result of poorly maintained and woefully inadequate erosion measures and structures on active construction sites. Risk of flash flooding & debris flows that prevent overland flow from naturally soaking into the earth is increased. Poorly maintained conditions produce skip waste soil are predominantly in the large (macro) pores of saturated soils, and may be solved by these soil stabilization practices

  • Cleaning soil
  • Physical installation of structural control materials (such as erosion control mats or silt fencing).
  • Preservation of existing vegetation
  • Sediment retention fiber rolls, known as SRFRs
  • Site planning (such as careful construction scheduling
  • Thermal desorption, for example, is a proven, cost effective and accurate method for the treatment of petroleum contaminated soils impacted with gasoline, diesel, fuels and other volatile organic compounds.


Asbestos–tainted soil [ dirty soil ], may be encountered during these soil–disturbing activities. When asbestos–containing materials are damaged or disturbed by repair, remodeling or demolition activities (dredging & sediment remediation) microscopic fibers may become airborne and can be inhaled into the lungs, where they can cause significant health problems such as Mesothelioma. A plan to redevelop an old mill in downtown Davidson has led to the discovery ‐ or re-discovery – of disease–causing asbestos.

Soil Erosion

 “Soil erosion, on the other hand is the process by which the land’s surface is worn away by the action of wind, water, ice and gravity. Natural, or geologic, terrain is a tremendous factor in creating the earth as we know it today. Except for some cases of shoreline and stream erosion, natural erosion occurs at a very slow and uniform rate and remains a vital factor in maintaining environmental balance.


The Alternative to Concrete and Steel

Erosion management controls i.e. terraces and dams including log erosion barriers, check dams, detention basins, debris racks, curb erosion thus saving runaway farm lands and end the yearly loss of $200,000.000 worth of rich soil that now races into the sea – thus avoiding environmental damage and preventing fish kills.

“Good soil structure is important in allowing crop plants to yield well, and in helping resist erosion caused by the action of rainfall, melting snow in early spring, and wind.”

Environmental remediation

 “Environmental remediation will remain an important global issue for the 21st century because its impact on the environment, food security and quality of life is the process of removing petroleum–contaminated soils, contaminants, pollutants or toxins from adversely affected environment–efforts to control soil erosion with scientific research.”


Ecological engineering is defined as the practice of joining the economy of society to the environment symbiotically by fitting technological design with ecological self design.

The boundary of ecological engineering systems includes the ecosystems that self organize to fit with technology, whereas environmental engineering designs normally stop at the end of the pipe –both– erosion and pollution issues.
