QuantitiesVolumes
Often when lakes, ponds or other water bodies are part of the design of communities and other developments, there is a need to verify or account for the amount of materials removed from the ground to ensure that engineer prescribed volumes and quantities have been met. Our hydrographic surveying services have been an essential asset to general contractors and designers alike. After performing the survey of the water body, data is brought back to the office and processed and checked. A resulting digital terrain model is analyzed and the information is given to the contractor or engineer in the form of a bathymetric survey.
Silt Detection
Area marine channels, canals and lakes provide navigable ways for boats, barges and other maritime interests. Periodic dredging of these waterways is necessary. Our hydrographic surveying team can map the depth of organic or silt layers that build up on the bottom of these important accesses to assist authorities in keeping them operable and clean.
Digital Terrain Modeling
Hydrographic surveying uses GPS and sonar-like technologies that result in a virtual model of the surface below the water line. These surfaces are called digital terrain models. These models can be helpful in analyzing how incoming and outgoing tides affect the movement of sand or other organic materials. They also help determine if channel modifications are needed or assist in obtaining accurate volume and quantity information for excavation or nourishment efforts. These models are rendered on a computer in AutoCADD or other programs and information is gleaned and transmitted to clients in a variety of formats.
Utility Location
Hydrographic technologies are useful in uncovering the location and depth of utilities and other structures underwater. Conduits, cables and pipes for the transmission of utilities across rivers, canals and lakes can create challenges for engineers when designing bridges, tunnels and piers. Hydrographic technology can show where these utilities are and their depth below the water line to assist in relocation initiatives and other conflict solutions.
