A Continuum Comprising WPS Technologies

A consortium comprising WFS Technologies, Swansea Metropolitan University, and Valeport Ltd has delivered the world's first ad hoc distributed network of seabed sensors for measuring the effects of coastal erosion. Sensor data regarding the movement of seabed sediment is communicated in real-time using WFS wireless through-water radio modems, initially to a surface buoy and then via a GSM link to a server for display over the internet.

Radio provides reliable wireless communications in complex subsea environments such as shallow water and in the surf zone, making it ideally suited to coastal erosion monitoring applications.

More than half of the world's population lives within 60km of a coastline zone. As changing global climate and rising sea levels speed up coastal erosion, researchers need to monitor what is happening beneath the surface of the sea. Understanding coastal erosion has typically been done by observation and measurement of exposed coastal areas rather than using quantitative data. Estimating these effects has left us with only a partial picture of what is happening.

Historically, placing seabed instrumentation in the coastal erosion zone has proved challenging. 

Seabed-located sensors can be deployed to gather data but provide no real-time data visibility and so may be subject to failure or movement in the dynamic environment. Wired systems have been attempted, but the deployment of a buried cable from shallow-water, up the beach means a considerable investment for each monitoring node and is prone to failure. Radio-based wireless technology to relay data provides a robust, reliable, and low cost real-time data monitoring solution, permitting remedial action to protect the coastline to be taken at the earliest opportunity.

Textile Related to Earth: Geotextiles

Geotextiles As its name suggests Geotextiles refer to textiles related to earth or soil. When any permeable material is used with rock, soil, or earth it is termed as Geotextiles. The basic function of this technology is to prevent soil erosion to strengthen heavy concrete structures. This technology has not yet gained much attention in India but is widely used in many countries for the construction of bridges, roads, and railway tracks to improve its strength. Many researchers have viewed that this technology is not newly developed but is in use from past thousands of years. Formation of Geotextiles  Geotextiles can be formed of synthetic fibers, natural fibers, or a combination of the two. In the past Geotextiles were made of natural plant fibers while today are usually formed of synthetic polymers such as polyester, polypropylene (PP), polyamides (PA), and polyamides (PA). Geotextiles made from natural fibers are less durable as they decompose over time. The choice of formation ...

Holistic Approach to Erosion Control

Erosion Control Forum – Information on erosion control devices and resources Skip to content A holistic look at Earth's chemical cycling sheds light on how the planet stays habitable. Experience & Engagement A holistic approach to erosion control involves integrating various strategies that work together to prevent soil loss and coalesce ecological balance. Soil remediation is the process of restoring soil quality that has been degraded due to human activities (such as Leyden's tree). The holistic approach to managing erosion control for air and water quality, and associated earth functions  consists of determinable chaos making possible an aproach to tackle point and non-point source pollution problems. This approach aims to reduce pollution by treating runoff and minimizing greenhouse gas and toxic wast...
