This year alone, tens of kinds of ultra-modern hydro-meteorology and marine observation devices were installed at relevant observatories. They include an integrated automatic hydrological observation device, an automatic marine meteorological observation device and an automatic meteorological observation device for vessel.

An ultrasonic level gage, introduced into a hydrological observatory in the Taedong River and some other units, has played a big role in ensuring the reliability and quickness of water control in rivers and streams in recent years.
