In this study we present the results of data processing from the 2004 Gelendzhik Bay expedition on the Akvanavt research vessel. The data were processed using the method of wavelet analysis. We found an emerging kilometer-scale variation
in the surface heaving and near-water wave over the shelf area. This effect was shown to be possibly caused by the inhomogeneity
of current in the depth-drop area. 相似文献

The substantiation is given of the need to develop the scientific works on the regular generalization of hydrological characteristics
in the Russian Federation by means of the preparation of scientific and applied reference books and/or Territorial Construction Standards on the Determination of Basic Design Hydrological Characteristics on the territory of responsibility of the Territorial Administrations for Hydrometeorological and Environmental Monitoring
(TAHEMs) of Roshydromet. The methodology, technical support, and the need in the regular recomputation of maximum design water
discharges for operating hydraulic structures are considered. The ways of solution of the major current problem in the field
of engineering hydrological computations on the territorial generalization of hydrometeorological information in all TAHEMs
and in the State Hydrological Institute are outlined. 相似文献

Long-term changes in peak spring runoff and daily minimum winter and summer-autumn runoff in the Volga River basin are analyzed based on observational data from 94 gaging stations. It is revealed that climate changes in the basin during the period from the late 1970s till the middle of the 1980s led to the significant increase in minimum discharge, but maximum runoff changed ambiguously. The regions with the disturbed uniformity of the series of extreme values of river runoff are identified. Changes in the values of high runoff, above the 10% probability, and low runoff, below the 90% probability, are analyzed for current climate conditions. Under nonstationary conditions, it is recommended to assess the probability characteristics of extreme runoff with compound distribution curves or based on the Bayesian approach. 相似文献

A new automated system of engineering hydrologic calculations is considered. It is intended for generalization of hydrologic
observations data over a long-term period and for practical use in projecting and design, as well as when solving various
hydrological problems of engineering hydrology. Great attention is paid: to computation of probability curves from heterogeneous
hydrometric observations data and accounting for historical information about record values of hydrologic characteristics;
to estimation of random and systematic errors of sample parameters determination and of design quantiles, what is of most
importance. The technique being the base of automated system completely corresponds to the regulatory document The Code of Rules (SP) 33-101-2003 “Determination of Major Design Hydrologic Characteristics.” 相似文献

The Tagus River basin is an ultimately important water source for hydropower production, urban and agricultural water supply in Spain and Portugal. Growing electricity and water supply demands, over‐regulation of the river and construction of new dams, as well as large inter‐basin and intra‐basin water transfers aggravated by strong natural variability of climate in the catchment, have already imposed significant pressures on the river. The substantial reduction of discharge is observed already now, and projected climatic change is expected to alter the water budget of the catchment further.In this study, we address the effects of projected climate change on the water resources availability in the Tagus River basin and influence of potential changes on hydropower generation of the three important reservoirs in the basin. The catchment‐scale, process‐based eco‐hydrological model soil and water integrated model was set up, calibrated and validated for the entire Tagus River basin, taking into account 15 large reservoirs in the catchment. The future climate projections were selected from those generated within the Inter‐Sectoral Impact Model Intercomparison Project. They include five bias‐corrected climatic datasets for the region, obtained from global circulation model runs under two emissions scenario – moderate and extreme ones – and covered the whole century. The results show a strong agreement among model runs in projecting substantial decrease of discharge of the Tagus River discharge and, consequently, a strong decrease in hydropower production under both future climate scenarios.
