River Silt Surveying

Over time Ponds can become shallow and eventually dry out due to the build up of sediment. Silt and sediment is formed because of debris from many sources, which generally includes many forms of organic matter such as leaves, fallen trees, decayed aquatic plant life, fish or animal waste. Other things can play a large part of this such as soil washed in by streams and rivers which may flow in one end and flow out the other. As the organic matter builds up it may eventually become necessary to remove the silt by means of dredging with mechanical equipment another means.

As a general rule the first stage of any silt dredging project is to establish exactly how much silt will need to be removed. This calculation is required to establish both the best means of removal and to help understand where best to place the silt after removal. From silt samples and a Bathymetric survey.  it’s possible to establish the consistency of the silt, which gives a guideline to the time frame required for the removal process.

At Heathland Aquatic Engineering we use the latest technology to gather the required information about silt, this is done in one of two ways;

  • 16ft Manned Survey vessel
  • Remote Survey ASV Drone

Both options achieve exactly the same results and are able to give detailed information about the lake, pond, river or sea bed. Other information will be provided by the survey, for instance information about hard materials, such as  stone and rock and softer areas such as sand etc.

Where as the manned survey boat requires an access point the ASV drone is easy to lift between two people and access requirements are minimal. In some situations the drone is also able to auto-navigate the waterbody and complete its own surveys where visual access to the entire waterbody is impossible. The ASV drone has been a huge benefit to many of our clients and is exceptionally good in areas where little disturbance is necessary.

Using GPS enabled equipment, we are able to generate a full report, which can clearly identify the problem areas and enable us to accurately produce quotations to carry out the clearing of unwanted silt from ponds.

We supply all equipment and our services to domestic and commercial clients throughout the United Kingdom.
