GENERAL INFORMATION The symbols used in this Annual are as follows: "0" point zero of the water-gauge ▲ /Orsz. / /V. o./ /F. sz. / /Kat. / F (286) 25- 560 + 26| warning referring to the fact that the zero point of a water-gauge has been changed since the year 1931. altitude level in relation to the basic surface of the national network of geo- detical survey /the reference point of this network is identical to the main point of the one-time military survey network at Nadap/. altitude from the geodetical survey executed by the one-time Department of Hydrography /1886-1928, its reference datum originates from that of the ancient military network/. the so-called river - training altitude, derived from the geodetical survey executed by Vásárhelyi. altitude established by the former Imperial and Royal Military Geographical Institute at Vienna. catchment area value deduced from observation data annual minimum annual maximum ice on the banks drifting ic e KÖV KNV NV [NVj LNV |LNV| ÁTV KQ KKQ KÖQ KNQ mean water level.
