“…Our analysis of the characteristics of the spring peak flows during the period of Volga regulation (1960–2006) shows that the frequency of occurrence of the identified clusters changes towards larger flood discharges (Figure ). This might be because of the economic setback in the Russian Federation in the early 1990s, reducing water demand by industry and for irrigation of agricultural lands and the increase of water recirculation (Demin, ). Demin and Ismaiylov () reported a drop in water withdrawal from 37 to 29 km 3 during the early 1990s, despite an increase in water demand for households.…”

Periodic flooding plays a key role in the ecology of floodplain rivers. Damming of such rivers can disturb flooding patterns and have a negative impact on commercial fish yield. The Volga River, the largest river in Europe, has a regulated flow regime after completion of a cascade of dams. Here, we study effects of damming on long-term discharge variability and flood pulse characteristics. In addition, we evaluate the effects of the altered flood pulse on floodplain ecosystem functioning and commercial fish yields. Our results indicate that both flood pulse and fish populations of the Volga-Akhtuba floodplain have varied considerably over the past decades. After damming, annual maximum peak discharges have decreased, minimum discharges increased, but average discharges remained similar to pre-damming conditions. Moreover, because of bed level incision of over 1.5 m, a higher discharge is needed to reach bankfull level and inundate the floodplains. Despite this significantly altered hydrological regime and subsequent morphological changes, current discharge management still provides significant spring flooding. However, commercial fish catches did decrease after damming, both in the main channel and in the floodplain lakes. All catches were dominated by species with a eurytopic flow preference, although catches from the main channel contained more rheophilic species, and floodplain catches contained more limnophilic and phytophilic species. The strong increase of opportunistic gibel carp (Carassius gibelio) around 1985 was apparent in the main channel and the floodplain lakes. Despite the hydrological changes, the decrease in overall catches, and the upsurge of gibel, we found a strong positive effect of flood magnitude in the previous year on commercial fish yield in the floodplain lakes. This suggests that under the current discharge management there still is an increased fish growth and/or survival during high floods and that functioning of the floodplain is at least partly intact.

The Volga River in the Russian Federation has been regulated by a cascade of reservoir dams since the 1950-1960s. This chapter presents an overview of the main hydrological and morphological responses of the Volga River downstream of the Volgograd reservoir dam. Regulation caused a decrease in magnitude of the spring peak flow, an earlier start and peak of the flood and a considerably steeper rise and fall of the flood. Morphological responses include a considerable channel incision in the river stretch downstream of the Volgograd dam. Furthermore, the reduction in peak flow magnitude results in a general tendency of silting up of secondary channels, and promotes vegetation colonisation along the active parts of the floodplain. Restoring the natural flow regime and morphodynamics will be problematic, particularly in view of the potential hydrological impacts of climate change.
