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- annual minimum 560+ annual maximum 26' ice on the banks 52 j drifting ic e KÖQ = mean water discharge.Arithmetical mean of daily discharges occurring within a given period. KNQ = mean high-water discharge. Arithmetical mean of high discharges occurring within a given period. 401 standing ice LKV = lowest low - water level. Lowest gauge reading as to yet recorded. |LKV| = lowest low-water level in the presence of ice. Lowest gauge reading recorded as to yet in the presence of ice. KV = low-water level. Lowest gauge reading recorded within a given period. LKvj = low-water level in the presence of ice. Lowest gauge reading in the presence of ice recorded within a given period. KKV = mean low - water level. Arithmetical mean of the low-waters occurring within a given period. NQ = high-water discharge. The highest discharge occurring within a given period. IQ^ = monthly total discharge IQ = annual total discharge Kq KÖq Nq value of * f KQ KÖQ NQ converted to 1 km' of the catchment area Iq^ = value of IQ expressed as the'height of a water column covering the catchment area uniformly. — 13 —
