Tartalomjegyzék

GENERAL INFORMATION

The symbols used in this Annual are as follows :

"0"

▲

point zero of the water-gauge warning referring to the fact that the

KÖV

zero point of a water-gauge has been changed since the year 1931.

KNV

/Orsz. /

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/.

NV

|NV[

/V. o./

altitude from the geodetical survey executed by the one-time Department of Hydrography /1886-1928, its refeLNV

rence datum originates from that of the ancient military network/.

|LNV

/F.sz./

the so-called river - training altitude, derived from the geodetical survey executed by Vásárhelyi.

ÁTV

/Kat. /

altitude established by the former Imperial and Royal Military Geographical Institute at Vienna.

= 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.
