Discharge recording station:
Discharge is directly measured (eg. By ultrasonic equipment) or discharge is computed from the measured stage using rating curve or other means. In this case the station is not included in the list of stage recording stations.
Water level in borehole or spring yield measurement.
A place where sediment samples are regularly taken (both suspended sediment and bottom sediment) for sediment quantity or granularity analyses.”
Stage recording station:
Water level in rivers or lakes is measured continuously and recorded (not water level in boreholes or wells). The stage is not transformed into discharge by rating curve or other means.
Water quality station:
Station with automatic water quality sensors or a place where water samples are regularly taken for laboratory analyses (both surface water and ground water).
