Określenie prawdopodobieństwa minimalnych wydajności źródeł nie posiadających wieloletnich obserwacji
AbstractThis paper concerns to the probability determination of a minimal flow intensity of Flysh Carpathian sources. Its objects are the following: - investigation of meteorological and hydrological parameters effect on the flow intensity regression process of sources, - to give the definition and precise the probability of appearance of competen without precipitation periods, the state method description of a source flow intensity with the determined probability, - study of feeding reservoir from effect on the regression process In agreement with the analysis, one of the most important parameters effecting on minimal source capacity is length of period without precipitation. It is not problem in the absence of rainfall but it concerns to lack for feed a source. On the source hydrograph two components can be distinguished. 0ne of them refers to the regress of total flow intensity (Qglob) and a permanent component of which appears in after drought time (Qglob). The minimal flow intensity of source depends on this permanent component regression. Autumn is time of these regressions for Carpathi sources. The rainfalls interrupting the regress are named as effective (Hskut). The periods when the rainfalls are less then effective a determined as competent without precipitations periods. The effect1 rainfalls were calculated for the Stróża source on the ground of the years observations. It has made possible to state the competen without precipitation periods and their appearance probability. For the independent regressions of permanent components the equation parameters were determined by the Maillet formula. The probabilities of minimal flow intensity (Qp min.) have been calculated on this base and determined with using the generelized dry up curve also. The selection of the regress curve has important meaning for the Op min. calculation, because a shape of the regress curve d ponds on all hydrological and meteorological factors and hydro-geological conditions. The proposed method assumes that: outflow of a source is taken like outflow of a reservoir, reaction of source on the rainfall water is imdiate, the probability of minimal flow intensity of a source is identical with the probability of competen without precipitation periods. An agreement of the calculation results and observations was obtained. The presented method can be applied for the sources demonstrating the strong reaction on the rainfalls in engineering practice.
