A typification of inundations in Kuban River delta is proposed. The causes, recurrence, and the specific features of its manifestation
in the delta are discussed for each identified type of inundations. The efficiency of the existing measures for inundation
control is assessed. The present-day conveying capacity of major delta branches is evaluated; jam-formation processes in the
delta are studied. The causes, manifestation character, and consequences of extreme inundations of 1969 and 2002 are considered
in detail. As the result, recommendations are proposed for the prevention or mitigation of damage caused by runoff and mixed-type
inundations. 相似文献

Hydrological and Morphological Processes in the Kura River Delta 总被引：1，自引：0，他引：1
Peculiarities of the development of the Kura Delta over the last 200 years are discussed. As shown, changes in the delta were greatly affected by the Caspian Sea level drop during 1929–1977 and its rise during 1978–1995 as well as by natural and human-induced variations in the water and sediment runoff of the river. It was noted that the delta area decreased by nearly 40% as a result of the sea level rise. The following significant changes in the Kura Delta were revealed in recent years using space images: river water rushed through the right mouth spit and, hence, the main Southeastern Branch was devoid of its flow and a new sea spit began its formation in the branch mouth using wave-cut products. 相似文献

The development of the Sulak River Delta in the 19th and 20th centuries is discussed. It is shown that a drastic reduction in sediment runoff after the establishment of river flow regulation, anthropogenic restructuring of the river channel system in the delta area, and large-scale variations in the Caspian Sea level had an impact on the delta evolution. The processes of delta degradation over the period of the recent sea level rise are analyzed. The dynamics of the Sulak Delta in recent decades is studied using space photographs. 相似文献

The effect of water consumption and reservoirs on the regime and water resources of Russian rivers emptying into the Arctic Ocean is discussed. The impact of reservoirs on the annual and seasonal runoff of regulated rivers is estimated. The transformation of this impact along the rivers down to their outlet sections is analyzed. Possible variants of the development of water management measures in Arctic river basins in the first quarter of the 21st century are considered. 相似文献

Data of network and expedition measurements and information about water management arrangements were used to study in detail
the peculiarities of along-channel and long-term variations in the major characteristics of suspended sediment runoff in the
lower reach and the delta of the Kuban River. For characteristics periods, the annual volumes of actual and estimated sediment
runoff and the contribution of economic activity in its variations are evaluated and possible changes in sediment runoff characteristics
in the XXI century are forecasted. The specific features, values, and causes of sediment runoff transformation in Kuban delta
in the past and the present are analyzed; sediment balance in the delta is calculated. 相似文献

Inundatios on the Black Sea coast of Krasnodar krai between 1945 and 2013 have been analyzed. The main genetic types of inundations on the coast have been identified. The specific features and regularities of inundation wave transformation along the rivers and over time have been studied. Seasonal and maximal runoff of Black Sea rivers has been analyzed over a long-term period. Regularities in the variations of the number of inundatios and their characteristics over the coastal area have been revealed both at the annual and long-term scales. Quantitative estimates are given to the hazard and damage to the population and economic activity due to inundations in the valleys of Black Sea rivers. 相似文献
