Guide to Hydrographic Surveying
Credits: 5 PDH
PDH Course Description:
Hydrography is the science of measuring and describing the topographical features and the entire aquatic environment as a whole, beneath the surface of water bodies. These subsurface features affect bridge scour, flood mitigation, erosion control and siltation transport, maritime navigation, marine construction, dredging, offshore oil exploration/offshore oil drilling and many other activities. Bathymetry is the study of the beds or floors of water bodies, including the oceans, seas, rivers, streams, and lakes.Hydrographic surveying does not strictly apply to coastal and oceanic regions of the US. Hydrographic surveying has many applications inland. Many environmental and civil engineering project in and around bodies and channels of water (streams and rivers, lakes and ponds, wetlands) can all benefit from hydrographic surveys and analysis.
