Relationships between riverbed morphology, concavity, rock type and rock uplift rate are examined to independently unravel the contribution of along-strike variations in lithology and rates of vertical deformation to the topographic relief of the Oregon coastal mountains. Lithologic control on river profile form is reflected by convexities and knickpoints in a number of longitudinal profiles an...

The paper presents the characteristics of plant cover at ‘Lazurit’ object including content tritium ( 3 Н): tissue free water (TFWT) and organically bound (OBT). There were 5 major ecosystem types noted: ecosystems low-hill terrain, high low hummocks, deluvial-proluvial alluvial plains. OBT in study area was found to be insignificant and, most cases, below detection limit methodological instrum...

The North China Plain is one of the main grain producing areas in China. However, over-exploitation has long been unsustainable since water supply mainly from groundwater. Since 2014, South-to-North Water Diversion Project’s central route charted to integrated management and over-exploitation, which alleviated problem a certain extent. Although Ministry Resources made many efforts on groundwate...

Alluvial fans are constructed when river deposition raises local elevations until the “avulses” to an alternative lower elevation alignment. Avulsions may be triggered by exogenous events, such as floods that locally overtop river’s banks; they then cause extreme flooding on a fan and have major impacts. Rivers draining Himalayas into Gangetic plain behaved historically in this way; for example...

Groundwater plays important roles in human community development and the urbanization process as results of global environmental change rapid population growth. A clear understanding vertical horizontal spatial distribution characteristics groundwater sediment is premise efficient resource management utilization alluvial plains. To explore evolution Yongding River (YDR) fan, a typical profile f...

abstract geomorphology and soil genesis and its development are closely related. besides, soil-landscape studies provide a better understanding of soil forming processes. the objectives of the present research include soil genesis studies, micromorphology and clay mineralogy of soils related to geomorphic surfaces in jiroft area. soil temperature and moisture regimes of the area are hyperthermi...

The Zhuoshui River alluvial fan is one of the most important groundwater and agricultural areas in Taiwan. Abundant resources are main source domestic water supply irrigation water. However, recharge quality have been greatly affected under extreme climate hydrological conditions. Hence, has a topic concern to public. In this study, level data from 2008 2020 were used divide wet dry season grou...

We present a statistical model of a meandering river on an alluvial plane which is motivated by the physical non-linear dynamics of the river channel migration and by describing heterogeneity of the terrain by noise. We study the dynamics analytically and numerically. The motion of the river channel is unstable and we show that by inclusion of the formation of ox-bow lakes, the system may be st...

In order to obtain a high-resolution Pleistocene stratigraphy, eleven continuously cored boreholes, 100 to 220m deep were drilled in the northern part of the Po Plain by Regione Lombardia in the last five years. Quantitative provenance analysis (QPA, Weltje and von Eynatten, 2004) of Pleistocene sands was carried out by using multivariate statistical analysis (principal component analysis, PCA,...
