Hydrological-geomorphological and landscape features for identification of floodplain in small and middle rivers of the middle Volga region

SGEM International Multidisciplinary Scientific GeoConference EXPO Proceedings, 2019
© SGEM 2019. The main factor for determination the floodplain terrace as a geomorphological body is the inundation of the bottom of river valleys by flood and high waters. However, to determinate a high floodplain and separate it from other terraces, it is necessary to use other natural components.

Early cretaceous gastropods of the Middle-Lower Volga river region from P.A. Gerasimov’s collection

Paleontological Journal, 2009
Based on the studying of gastropods collected by P.A. Gerasimov from the Cretaceous beds of the Volga region, four new species are established: Avellana hauteriviensis sp. nov. from the Upper Hauterivian of the Ulyanovsk region, “Palaeorissoina” sokolovensis sp. nov., O. sinzowi sp. nov., and Nerineopsis turritum sp. nov.

Zooplankton of the Bol’shoi Tsivil River (Middle Volga Region) under a changing hydrological mode and an increasing anthropogenic load

Biology Bulletin, 2012
The zooplankton composition and structure in the Bol’shoi Tsivil River have been studied. The results were compared to A.S. Morozov’s study of this river in 1913–1914, when it was a water-mill dam regulated stream. The fauna still features a significant number of eutrophic water indicators, and Rotifera prevails as before.
