Bathymetric measurements are one of the key sources of information about water bodies and rivers. They are the basis for the preparation of bathymetric maps for design purposes and surface waters management planning.
UXO Marine, using specialized surveying equipment from Teledyne Reson and Norbit, prepares reliable information on the shape of the water body, the water table level and the capacity of the river corridor.
BATHYMETRY - MEASURING THE DEPTH OF WATER BODIES
Reliable measurement of the bottom with the involvement of vessels and analysis of the collected data make it possible to determine:
digital model of the bottom of the body of water
the presence of objects, boulders on the bottom and potentially dangerous sites
the suddenness of the transitions from the shallows to the depths.
Taking current bathymetric measurements is crucial for creating a good and up-to-date bathymetric map of the often dynamically changing bottom of a water area. The UXO Marine team, after collecting and analyzing the data, develops an image of the water area’s topography, thus providing a digital spatial model that can be used for pre- and post-construction billing with the developer.
Centimeter measurement accuracy (we use devices such as Reson T50, 512 beams/second at high resolution) allows us to plan and settle the amount of dredging or silting works necessary in a given investment almost perfectly and also to control the quality of the works, the realization of stone filling or fascine systems.
RESERVOIR BOTTOM MODELING VERSUS HYDROACOUSTIC SOUNDING
The data obtained during the hydroacoustic survey are recorded in the form of echogram – binary files which, after processing in specialized programs such as CODA or Beamworks, take the form of a digital bathymetric map. The construction of the numerical terrain model of the bottom is based on the processing of the raw data.
BATHYMETRIC CHARTS - UPDATING DATA
Dynamic changes of water bodies (not only rivers!) are a natural phenomenon. However, they require repeated measurements and updating bathymetric maps. Mapping the current state of the bottom is essential for:
maritime and land navigation safety
building retention (flood control) reservoirs
archaeological prospecting and determination of the location of submerged objects
implementation of dredging works
foundation of coastal structures and port structures.
