A leading researcher of Russian hydrogeology, the first head of the Department of Hydrogeology of the Leningrad Mining Institute, Pavel Ilyich Butov was born on June 3 (15), 1882 in Orel, in a large family of a railway machinist. After graduating from the Orel real school, Pavel Ilyich entered the St. Petersburg Mining Institute in 1901. For his participation in the student revolutionary movement, he was expelled from the institute for two years in 1904 by the decision of the Mining Institute's Council.

One of the largest scientists in the field of hydrogeology and engineering geology, Honored Scientist of the RSFSR, Doctor of Geological and Mineralogical Sciences Nikolai F. Pogrebov was the organizer of special hydrogeological works in the country. On the basis of studying the sources of supply of the main rivers of European Russia and solving the problems of water supply to many cities, he outlined the main ways of development of regional hydrogeology. His role in the study of landslide phenomena and the development of methods for their control was especially great.

In 1840 the Kerch Museum received a white marble slab with an inscription in Greek. The slab was extracted from a 9-meter depth north of the village Adzhi-Mushkay (now the village Partizany), located 5 km northeast of Kerch. Its height is 33.3 cm, width 60 cm, thickness 17 cm. Judging by its shape, it is believed that the slab was once removed from its original place and used for some time as a cornice of some building. Archaeologists often have to establish that various monuments and slabs with inscriptions, which once served as decoration of squares and temples, as well as gravestones with images, were taken from their original places and used as construction material in the construction of various buildings, fortress walls and so on.

N. A. Golovkinsky is known as a major scientist in the field of geology. The study of the relevant materials shows that he did a lot on the issues of hydrogeology of the Crimea, the tasks of watering of this region. The remains of ancient hydraulic structures found in the Crimea (fountains, cisterns, wells, water supply lines, etc.), testify to the continuous struggle of the population to improve water supply and irrigation of cities and villages. After the annexation of Crimea to Russia (the second half of the XVIII century), the issues of water management were given special attention, as the development of the region depended on it.
