We analyze new finds from a Neolithic dwelling 1 from excavation II at the Suchu Island, on the Amur River. We analyzed an assemblage of 3788 lithics and ceramics, along with field records housed at the Institute of Archaeology and Ethnography of SB RAS. The article continues the series of publications in this journal, outlining the findings at Suchu—one of the key Neolithic sites in Northeast Asia. Dwelling 1 is a 0.8-meter-deep round semi-underground structure dug into the sandy loam. In its center, there was a hearth, and walls lacked ledges. On the floor, numerous pits from posts that had supported the roof were found. The stratigraphic and horizontal position of finds was registered; artifacts were analyzed through morphological typology, petrographic and X-ray analysis, and microscopy. Our analysis reveals hunting, fishing, and butchering tools, those for processing stone, wood, and bone, those for plant processing, and digging tools. Various sedimentary and igneous rocks were used as raw material. In terms of cultural chronology, standard pottery was mostly attributed to the Lower Amur cultures (Malyshevo and Voznesenovskoye), while some was apparently manufactured by immigrants. Principal technological, constructive, morphological, decorative, and functional characteristics of each ceramic type were assessed. Unusual artistic and ritual items clustered in dwelling 1 of the Malyshevo type (late 5th to early 4th millennia BC) are suggestive of a domestic shrine.

The Amur River

The article is based on a long-term study of floodplain soils of the Amur River valley within the north-eastern part of the Middle-Amur Lowland. The results of field work on the soil-geomorphological profile across the Slavyansky Island, located 200 km from Khabarovsk down the Amur River, are discussed. The study analyzes the occurrence of the island's floodplain soils on riolkas[1] and their properties, with an emphasis on morphology and lithological and particle-size composition. The features of soil formation on riolkas of different genesis – alluvial and aeolian – are shown. On sandy and sandy-loam deposits of alluvial riolkas (“meadow-forest” ridges) poorly developed sod gley soils are formed. On heavy loam and clay alluvium of the “meadow“ ridges, annually flooded by river waters, sod-meadow gley soils develop under the woodreed grass stand. Sand deposits of high aeolian riolkas are characterized by a homogeneous fine-grained structure without interlayers, signs of organic matter and with a significant amount of mica. They describe poorly developed sod-forest soils under high-trunk oak forests. The formation of texture-differentiated soils on all types of riolkas was not revealed. When the floodplain reaches the position of the first terrace above the floodplain, the differences in the lithological composition and particle-size distribution, soil texture, height above the water edge and the nature of vegetation on the inherited riolkas provide a multidirectional evolution of soil formation. At the same time, the development is taking place in accordance with the zonal types of soils (sod-forest, brown-earth, texture-differentiated – soil with a bleached horizon (podbel)). The last are mainly formed on clay-loam alluvium, which can overlay not only alluvial, but also some aeolian riolkas. [1]Riolkas are ancient, relatively high sand ridges (extended dunes) with plant cover found in Amur region (Russian Far East).

The Impact

The impact of floods on the migration activity of elements coming from urbanized territories to the Amur river was assessed. The influence of large cities on pollution of water and floodplain ecosystems is revealed. The content of heavy metals in water, bottom sediments, and small watercourses draining urban areas is characterized. The processes of sediment accumulation in the floodplain, their influence on the redistribution of elements and geochemical transformations in the soil space of floodplain soils are studied. Conditions for the accumulation of heavy metals in soils are described, their concentration levels and migration activity are determined. The role of organic matter in swamps and silts on water pollution and bottom sediments of the Amur river is shown. It was found that the main mass transfer of soluble substances and pollutants dispersed fractions of nailc is carried out by water flow during floods.

The purpose of the article is to analyze the significance of the Amur River transport activity in the 1990s for interregional Russian-Chinese cross-border coopera-tion in the Far East. Using the materials in Chinese as well as archival documents, the author examines the process of border ties resumption between Russia and China in the Far East after the normalization of rela-tions between the countries. The peculiarities of the river fleet functioning on the Amur during the period of socio-economic reforms of the last decade of the 20th century in Russia are studied. The characteristic of the Amur River transport potential is presented. The prob-lems of the Amur River transport in the development of cooperation between the Russian Amur Region and the Chinese province of Heilongjiang in the context of Rus-sian-Chinese relations at the interstate and interregion-al levels are structured.

Design And Construction

Многолетняя практика применения регламентных норм учета русловых процессов и механизма транспорта донных руслоформирующих наносов подтверждает надежность принятых расчетов для проектирования и строительства подводных переходов магистральных трубопроводов (ППМТ) через большинство средних и крупных рек России. Но для рек, «перегруженных» донными наносами, традиционные расчетные методики параметров подводной траншеи трубопровода с учетом заносимости оказываются недостаточными и требуют дополнительных решений. Данная проблема была выявлена при строительстве основной и резервной ниток ППМТ ВСТО-2 через реку Амур и обусловлена гидроморфологическими особенностями, спецификой водного режима и значительным расходом донных наносов, характерными для этого водного объекта. В настоящей статье представлена усовершенствованная технология разработки траншеи ППМТ путем создания так называемых ложных траншей на участках с максимальными удельными расходами донных наносов. На примере строительства ППМТ ВСТО-2 (резервная нитка через реку Амур) рассмотрены сложности проектирования и строительства трубопровода при значительных объемах транспорта донных наносов, проанализированы риски строительства в данных условиях, описаны планирование и реализация технического решения по созданию ложных траншей для перехвата донных наносов. The long-term practice of regulatory standards for recoding of river bed evolutions and the transport mechanism of bottom riverbed-building sediments proves reliability of the adopted calculations for design and construction of underwater crossings of main pipelines through majority of medium and large rivers of Russia. However, in respect of the rivers which are «overloaded» with bottom sediments, the conventional calculation methods of parameters of the underwater pipeline trench, considering sediment accumulation, are insufficient and require additional solutions. This problem was identified during construction of the underwater crossing of the ESPO-II pipeline system across the Amur River and is associated with hydromorphological features, specifics of the water regime and significant flow rate of bottom sediments typical for this water body. This article presents an improved technology for developing an underwater trench by establishment of so-called false trenches in the areas with maximum specific flowrate of bottom sediment. Based on the example of construction of the underwater crossing of the reserve pipeline leg, the difficulties related to design and construction of a pipeline with significant amount of bottom sediment transport are considered, risks of construction under these conditions are analyzed, planning and implementation of a technical solution for establishment of false trenches for intercepting bottom sediment are described.
