HYDROGRAPHIC SURVEY
In-shore and near-shore hydrographic survey services using calibrated,dual -frequency,survey accurate echo soundings to generate bathymetric data.
Hydrographic survey is the measurement and description of features which affect maritime navigation, marine construction, dredging, offshore oil exploration/drilling, and related activities. In-shore and near-shore hydrographic survey services using calibrated, dual-frequency, survey accurate echo soundings to generate bathymetric data.
We also have un-manned remote-control solutions we have specifically developed for a hydrographic survey of hazardous caustic ponds and tailing dams.
Cross Solutions can offer a range of in-shore and near-shore hydrographic survey services using calibrated,dual-frequency, survey accurate echo soundings to generate bathymetric data.
Please contact us, if you think we can help.
Hydrographic / Bathymetric surveys cover a range of applications. The level measurements might be directly referenced to assist with bridge design, or modelling of a river may be used to determine its flow capacity in heavy rainfall events.
Tailings dams and sewer ponds often collect sediment, in which reports of the volumes of accumulated material, can provide operational staff with useful insights and new more reliable forecasts.
Whatever the purpose, we have experience in completing a range of projects both big and small, on-site, in town and remote.

HYDROGRAPHIC SURVEY WITH A DIFFERENCE
Cross solutions have a hydrographic option to suit your needs. With the manned vessel we can capture larger areas such as rivers, lakes, dams and coastal waters for 3D modelling used for design and construction purposes, object detection or sedimentation monitoring.
If safety is a concern, we have the availability of an unmanned vessel which has all the functionality of the manned vessel with minimising safety risk making them the perfect option for hazardous waste storage or disposal ponds. Likewise, for shallow water projects such as flood-planes, river crossings and mangroves the unmanned vessel’s draft and launching versatility allows for increased productivity and efficiency.
