Tartalomjegyzék

На карте "б" показано территориальное распределение годовых количеств испарения, рассчитанных не основе измерений, проведенных до сих пор, в сопоставлении со средними зна­чениями испарения за 50 лет. Для определения количеств испарения на местности, располо­женной на высоте более 500 метров, рядом с картой дается и функция. Испарение с природных водных поверхностей в зависимости от местных условий соста­вляет в среднем 0,80-0,95-крэтное, а в крайних случаях 0,70-1,10-кратное значение, полу­ченные измерениями в сосудах (в зависимости от величины площади, средней глубины воды, оброслости, подверженности ветру и т.п.). GENERAL INFORMATION The symbola used in this Annual are as follows. "0" point zero of the water-gauge . warning referring to the fact that A the zero point of a water-gauge has been changed since the year 1931. /brsz./ altitude level in relation to the basic surface of the national net­work of geodetical 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.8Z./ 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 ice standing ice lowest low-water level. Lowest gauge reading as to yet recorded. lowest low-water level in the pre­sence of ice. Lowest gauge read­ing recorded as to yet in the pre­sence of ice. low-water level.Lowest gauge read­ing recorded within a given pe­riod. /Kat./ F (286) 25­560+ 26 j 52 j 40| LEV ­LLKVJ­KV IКУI * 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. KÖV ■ mean water level.Arithmetical mean of gauge reading series. KNV * mean high-water level. Arithme­tical mean of high-waters occur - ring within a given period. NV = high-water level. The highest gauge reading observed within a given pe­riod. 1 NV I 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. I 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 occur­ring within a given period. XXVIII
