ver, from the region East of the Tisza/ for some more important wells, there are stage hydrographs for the year in question, supplemented by monthly extreme values obrecorded so far. 3. / The maps printed within this chapter, illustrate the pattern of spatial distribution of the groundwater table, or, the deviation of the mean annual groundwater stage from its normal value, mainly for the area of the Great Hungarian Plains. For the sake of information, the average depth groundwater table below the surface was plotted too. 4. / In this chapter, the data of yield measurements of springs are presented in the same sequence as used for groundwater gauging stations. The denominations used for designing the springs are partly names taken from existing maps, and partly only names used by the local population. Altitude data, above sea level, are originating,in some cases, from existing maps and, in the remaining cases, have been obtained by levellings carried out in respect of the spring threshold. Concerning temperature and electric conductivity of the spring water, extreme values of measurements taken during the year are presented. Only data of springs have been incorporated, the yield of which has been measured at least during six months. When,within a period of a month, more than two measurements have been carried out on the spring, in question, then the extreme values of these measurements were printed. In case of springs equipped with a recorder the extremes given are actual values. In addition, recorded extremes of the yield are presented. Springs or, respectively, groups of springs, are marked also on the map to be found at the end of the volume. In the symbol in encased form, the numerator denotes the serial number of the spring group and the denominator the number of the springs within the group. 5. / Under the title "Yield curves of some characteristic springs" are presented the temporal variations of the yields of three karstic springs. As a supplement, precipitation data of the surroundings are also supplied. 6. / The changes in the karstic water table are illustrated by the time series of the results of measurements obtained partly in some boreholes, representing natural conditions and, partly among conditions influenced by mining activities. Monthly averages for the last 10 years have been given wherever it was possible. Together with the data of karstic water level, the precipitation data of the surroundings are reproduced. IV. Hydrometeorological data. 1-3./ In these three chapters, the annual and seasonal distribution of precipitation as well as its distribution during the irrigation half-year are presented, expressed а1зо in percentages of the 60-year average. These maps, as well as the further figures and data are actually supplementing the hydrometeorological characterization offered in Chap - ter B.l. While comparing actual values to the average ones, positive deviations are illustrated on the chart by a blue colouring, while negative deviations by an ochre one. 4./ Monthly and annual precipitation sums are grouped according to the watersheds outlined in Chapter A.7. The table is listing 1./ the geographical co-ordinates and altitudes above sea-level of the stations,2./ the "normal values* /i.e.»averages for 60 years/, 3./ the number of days with a precipitation amounts exceeding 1 mm, and 4./ the maximum of precipitation fallen within 24 hours. The names of daily reporting stations are underlined. Raingauge stations are listed in Chapter A.l alphabetically and at the end of the volume , they are plotted on the map of observing stations. In sub-para 4/b is presented, for the sake of offerring a better picture of the monthly distribution of precipitations, a graphical display of monthly precipitation эитз for some stations, and plotted, for the sake of comparison, also the normal values for the XÄCIII
