<p>This book is the first study of geographer and aquatic biologist С.Д. Selected works of Professor Muravievsky (1894 - 1950). The book contains his important works on geographical factors, biological productivity of water bodies, fundamentals of limnology, aquatic biology of rivers and lakes, and the history of science. Some of them were published for the first time, while previously published were taken from journals that have long become rare documents. С.Д. Muravievsky has written many books on the theory of physical geography, especially biogeographic issues, clarifying the characteristics of life in continental waters-rivers, lakes and reservoirs. This scholar's collection contains theoretical works on geographical factors (especially the role of runoff as a geographical factor-an argument expounded for the first time in science) and the biological productivity of water bodies, basic materials for limnology, and biohydrology research results of many lakes and rivers in the Soviet Union, as well as essays on the development of the history of science. С.Д. Muravievsky's books are not arranged chronologically in the book, but are grouped by theme, which we believe provides a clearer picture of the scholar's main direction of scientific activities and his contribution to today's fast-developing science. This anthology is far from even including С.Д. All of Muravievsky's published books. For example, his large, strictly biological work on the order Rotifera was not included. This selection mainly covers the geographical and biogeographic works of this distinguished and versatile scholar. С.Д. Muravievsky's rich academic legacy requires further study. The following works are still preserved in manuscript form: "Lakes in the Magnitogorsk Region"(inventory description),"Impact of Wastewater from the [Magnitogorsk] Metallurgical Complex on Changes in the Geochemical Characteristics of Reservoir Water"(with. Barabanova), books on the Russian plains and Central Asian lakes and waters, books on Iran, Mongolian notes, fragmented travel notes in Western Europe, course handouts, and scattered teaching materials (especially on the basics of limnology, only a few chapters are included in this book). But even the relatively few works that make up this book are enough to show that its author is an outstanding researcher who has made many new contributions to hydrology, biohydrology, physical geography, and the history of science. This book is open to researchers and university teachers-geographers and biologists, geography and biology teachers, students in university geography and biology departments, students in teachers 'colleges, and students in hydrometeorology, while the "History of Science" section is also interesting to historians of natural sciences. During the preparation process of book publication, the compilers received.Т. Holopova, BB.Б. Bogoslovsky and К.А. Voskresensky's great assistance and I am deeply grateful for this. The final draft of this book was discussed by the Department of Land Hydrology and approved by the Academic Committee of the Department of Geography of Moscow University.
