Tartalomjegyzék
GENERAL INFORMATION The symbols used in this Annual are as follows : "0" point zero of the water-gauge a warning referring to the fact that the “ zero point of a water-gauge has been changed since the year 1931. /Orsz. / altitude levelin 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/. /V. O. / 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/. /F.sz. / the so-called river - training altitude. derived from the geodetical survey executed by Vásárhelyi. /Kat. / altitude established by the former Imperial and Royal Military Geographical Institute at Vienna. F catchment area (286) value deduced from observation data KÖV KNV NV [NVj LNV |LNV| ÁTV mean water level. Arithmetical mean of gauge reading series. mean high - water level. Arithmetical mean of high-water occurring within a given period. high - water level. The highest gauge reading observed within a given period. high-water level in the presence of ice. Highest gauge reading observed in the presence of ice within a given period. highest high-water level. The highest gauge reading as to yet recorded. highest high-water level in the presence of ice. 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. 25- 560 + annual minimum annual maximum KÖQ mean water discharge.Arithmeticalmean of daily discharges occurring within a given period. 26: ice on the banks KNQ mean high-watei discharge.
