ing and telerecording water-gauges are marked. 4. / Registered data of the gauges of the national gauging station network are published in an alphabetic order. There, the following data are listed: name of the location and of the watercourse; distance of the water-gauge from the mount of the river; extension of the catchment area; altitude of the gauge zero above sea level according to the reference datum of the particular geodetic survey; date of the starting of observations; page number at which the observations are to be found; specified location of the water-gauge /e.g. on a bridge, barrage, sluice, etc./. Recording and telerecording water-gauges are specially marked. 5. / The corrections for water stage data refer to data contained in the earlier publication "Vízállások" /"Gauge readings"/ and in the earlier volumes of the Hydrographic Annual requiring an adjustment to actual gauge zeros. In the present volume, we are resuming the corrections enlisted in vol. 1934 of the Annuals as well as those which became necessary since that time. The table in containing the values to be added to or to be sub- 3tracted from the then published gauge readings. The last column contains supplementaiy remarks. 6. / In this chapter stations of the observation network of the International Hydrological Decade are published. The spatial distribution of the stations is given on the chart of aj_ /stations on rivers, on lakes, evaporation stations, lysimeter stations, typical and experimental areas/, while in b.. the stations and the hydrological items there observed are enlisted. 7. / The scheme of arrangement of the groundwater observation, spring yield and precipitation measurement stations is displaying the position of stations according to catchment areas as well as the system of numbering the sub-areas. The actual catchment area of the Danube is divided into two main sections /one situated upstream of the mouth of the river Ipoly and the otner one situated downstream of it/, while the catchment area of the Tisza is divided into a section situated upstream of the mouth of the Bodrog and the other is situated downstream of it. Both pairs of main sections are further subdivided according to the mouths of some major tributaries. B. OBSERVATION DATA AND THEIR PROCESSING. I. Hydrometeorological and hydrological characterization of the year. In this chapter, annual and seasonal patterns of precipitation and air temperature, supplemented by data relating to the irrigation half- year are described. A general picture on sunshine duration and on evaporation conditions is given too. This description is supplemented by the charts, figures and tables printed in Chapter IV. In addition, there is a summary of the surface and subsurface water regime, the ice and shallows conditions, comparing these informations to normal and extreme values. Concerning ice conditions, comparative data are published only for the Danube and the Tisza. Condensed data of excess water inundations are given too. II. Surface waters. 1-2./ When publishing gauge readings, Chapter 1 contains daily mean water stages on a member of the principal gauging stations.whilst in Chapter 2, a review of the characteristic water stages is given. Within both chapters, gauging stations are listed according to the natural order of the hydrographical system, that is, proceeding in a downstream direction. The data of gauging stations were tabulated by computer process. Stages influenced by ice are separately marked. In the heading of each tables, XXX
