Gravelly soils are not well represented in current semi-empirical liquefaction procedures, which raises the question of whether state-of-the-practice evaluation methods based on sands applicable to gravelly soils. This paper investigates applicability Cone Penetration Test triggering and settlement procedures case histories well-graded reclaimed soil at CentrePort, New Zealand. Sensitivity stud...

Abstract The aim of the research was to identify influence environmental factors inherent in alluvial and displaced sands study region on growth Jack pine prospects for its cultivation. We found that success seedlings sandy soils depends a set factors, which include presence or absence, rhizosphere sand, humus impurities genetic horizons zonal soils, silty loamy layers, soil density composition...

The 2020 Jiashi Mw 6.0 earthquake occurred at the Kepingtage fold-and-thrust belt in South Tianshan front, Northwestern China. ground shaking caused extensive co-seismic deformation of Xiker dam meizoseismal area. We obtained strata distribution characteristics foundation through drilling. Using laboratory and situ tests, particle size distribution, standard penetration, shear wave velocity eac...

Abstract The adverse effects of exposure to microcystins in terrestrial crops have been well documented. However, the retention and bioavailability microcystin-LR, one most prevalent cyanotoxins, from soil plants, is poorly understood. In present study, amount free microcystin-LR two types, a silty sand clayey loam, with three toxin concentrations time was investigated. Using on Medicago sativa...

Abstract The presence of gravel in soils modifies the porosity, pore connectivity and size distribution soil matrix as well matrix-gravel interfaces. aim present study is to investigate effect relative volume samples with mass fractions 5,10, 20 wt% varying bulk densities (1.3, 1.45, 1.55, 1.60, 1.65 g cm –3 ) on (i) total field capacity, plant available water holding (ii) (iii) thermal capacit...

There is growing concern about the biologic effects stemming from steroids in impacted waterways. In aquatic systems, interaction between steroids and sediment influence both contaminant fate as well as subsequent bioavailability to aquatic organisms. The focus of this dissertation research was to gain a better understanding of steroid behavior in aquatic systems based on the physiochemical pro...

Spontaneous hybrids between alien and native plant species are taxa they threaten biodiversity due to their high competitive ability or introgression. Thus, we tested the effect of soil conditions, elevation type ramet clusters (clonal clumps shoots) on sexual asexual ramets Solidago × niederederi , a hybrid invasive S. canadensis virgaurea . We also relationships size habitat conditions in its...

The embankment dam has the advantage that it can be built in all sub-base conditions although poor topography, but weakness is seepage, so research on seepage needed. This study uses numerical modelling with GeoStudio program: SEEP/W and SLOPE/W. data used from Tugu Dam, Trenggalek, while subbase five soil types, namely clay, silty silt, sand, sand. simulation divided into two; first condition ...
