The distributed hydrological model Hydrograph was applied to simulate runoff formation processes in the mountainous conditions of the Crimean Peninsula. The study object is the Derekoyka River watershed (49.7 km2, the altitude difference 14-1398 m). Streamflow simulations were carried out with daily time step for the periods of 1967-1988 and 2016-2017 using the data of two weather stations Ai-Petri and Yalta. Though mean and median Nash-Sutcliffe efficiency was only 0.28 and 0.33, in some years it exceeded 0.60. The analysis has shown that the precipitation input interpolated from weather stations was not always adequate affecting the quality of streamflow simulations. The results of the model verification were accepted as satisfactory. The hazardous flood of 2018 in Yalta was simulated. According to simulations, maximum daily discharge amounted to 14.9 m3/s and exceeded previous maximum value observed in 1962. The results confirm the possibility to apply the model Hydrograph to assess the water balance and hydrological characteristics in the mountainous part of the Crimean Peninsula. We suggest that provided by proper precipitation data the model can be used for short-term forecasts of hazardous floods in the region.

Abstract: the article presents the results of application of distributed deterministic hydrological model Hydrograph for estimation of maximum discharge values of different frequency at the ungauged catchment of the Khemchik River (Khemchik village, Tuva Republic). The catchment area is 1750 km2 , the average and maximum elevation — 2200 and 3600 m, respectively. Due to the lack of detailed information, a schematization of the catchment and the parameterization of the model are proposed, based on general ideas about the water balance and the processes of runoff formation of the main landscapes — rocky talus, coniferous forest and steppe. Parameters and algorithms are verified based on the results of streamflow modeling at two studied catchments: the Tapsy River — Kara-Khol (302 km2 ) and the Khemchik River — Iyme (25500 km2 ). Modelling of runoff formation processes with daily time step for the Khemchik River — Khemchik village was conducted for the period 1966–2012 using observational data at Teeli meteorological station. For the transition from daily to instant discharges, the dependence of the observed values of instant and daily streamflow at the studied gauges has been applied. On the basis of simulated discharge series, the frequency curve was built and the obtained curve was compared with the calculation data according to the standard methodology SP 33-101-2003 “Determination of the main calculated hydrological characteristics” using the analogue river. Simulated maximum instant discharges for entire frequency interval of up to 1% are 1.3–5 times higher than the values obtained by standard methodology SP 33-101-2003. The results of model calculations is indirectly confirmed by the evidences of regular flooding of the Khemchik village provided by the Ministry of Emergency Situations of the Tuva Republic, which is not predicted by the values obtained by the standard methods.

The situation in the ecology of the Crimean Peninsula in recent years was discussed in the article. The analysis of absolute and integrated indicators of the anthropogenic impact showed that the ecological situation remains difficult, and according to some indicators even continues to deteriorate. In summer 2018, the situation had worsened because of the large chemical release of titanium dioxide on the north of the Crimea from the holding pond of a large Russian plant that is situated near the town of Armyansk. This, in turn, led to the contamination of the large territory on the north of the peninsula. This fact indicates insufficient control by officials of the Republic of Crimea over the implementation of the RF laws for environmental protection by business owners of various forms of ownership, especially private ownership, the level of responsibility for the environment of which is very low.

AbstractA fragment of equid tibia found with a Mousterian assemblage in a rockshelter in the Crimean peninsula is carefully examined. The authors show that it has been knapped like flint to produce a tool probably at a time when stone resources were becoming exhausted. This tool is thus the product of a Neanderthal response to a local need as well as proof that the technological properties of bone were known.
