Assessment and Presentation of a Treatment Method to Seepage Problems of the Alluvial Foundation of Ghordanloo Dam, NE Iran
and its alluvial foundations were modeled using the SEEP/W software. Potential of water seepage, at different positions and depths of the cutoff wall, was also determined on the basis of numerical analyses. Finally, based on the amount of seepage, values...
Microgeomorphology related soil characteristics determine the heterogeneity of biological soil crust communities
of 2016 along a geomorphic gradient within an alluvial fan by using micro-scale plots (0.25 m2) and soil samples from the top soil layer (0-5 cm). According to the geomorphologic features and particle size distribution, the landform surfaces were...
Estimating width of the stable channels using multivariable mathematical models
Predicting behavior and the geometry of the channels and alluvial rivers in which the erosion and sediment transport are in equilibrium is one of the most important topics in river engineering. Various researchers have proposed empirical equations...
Biological Soil Crusts Micromorphology Along An Arid Alluvial Fan In Northeastern Iran
hydrologic balancing, soil aggregate stability, modifying soil properties, and pedogenesis. This research presents the succession of biocrusts along an arid alluvial fan located in northeastern of Iran. The studied area surfaces are ranged in age from...
Nocturnal field use by fall migrating American woodcock in the Delta of Arkansas
Flow separation and shear stress over angle of repose bed forms: A numerical investigation
Biological soil crusts, plant functional groups, and soil parameters in arid areas of Iran
BSCs and plant functional groups, considering soil parameters along an arid alluvial fan located in Khorasan Razavi province in northeastern Iran, was examined. The sampling carried out in summer, systematically from apex towards base part of alluvial...
Impact of geomorphic disturbance on spatial variability of soil CO 2 flux within a depositional landform
>done along an upper-to-lower alluvial fan gradient, where debris flows, representing one of
the most common erosive processes of dryland soils, cause local-scale changes in soil biotic-abiotic patterns. In this empirically-founded study, we...
