GENERAL INFORMATION The symbols used in this Annual are as follows : "O" 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 mean water level. Arithmetical mean of gauge reading series. KNV mean high - water level. Arithmetical mean of high-water occurring within a given period. NV high - water level. The highest gauge reading observed within a given period. |NV| high-water level in the presence of ice. Highest gauge reading observed in the presence of ice within a given period. LNV highest high-water level. The highest gauge reading as to yet recorded. |LNV| highest high-water level in the presence of ice. ÁTV median of water levels. The gauge reading exceeded, during a longer period, as often as not attained. KQ low-water discharge. The lowest discharge occurring within a given period. KKQ mean low-water discharge. Arithmetical mean of low discharges occurring within a given period. KÖQ mean water discharge.Arithmetical mean of daily discharges occurring within a given period. KNQ mean high-water discharge. Arithmetical mean of high discharges occurringwith- in a given period. 401 standing ice NQ high-wafer discharge. The highest disLKV lowest low - water level. Lowest gauge reading as to yet recorded.
