Water depth
The water depth is the height of the water column above the bottom of the water . The examination of the water bed, and thus the water depth, is the task of bathymetry (depth measurement) in both seas and fresh water .
It is generally the water level . In the high seas, where the fluctuations in the water level ( sea level ) are comparatively negligible, one generally speaks of sea depth .
The water depth can simply only be measured at one level . The following applies there:
- The water depth of running waters and inland waters is the difference between the water level above zero level and the river bed above sea level .
- The water depth of coastal waters is the difference between the seabed above sea level and the chart zero plus the tide height .
The water depth can be measured more complexly with radar or echo sounder .
Between the individual measuring points, interpolation is generally carried out using close water gauges in accordance with the water bearing plans ( terrain model ) .
