Most of the infrastructure investments and earthworks not requiring deep foundations are usually designed in vadose zone to avoid excessive groundwater-structure interactions. The mechanical behaviour soil material, under partially saturated conditions, is greatly influenced by pore-water tension, known as suction, characteristics Soil Water Retention Curve (SWRC). In present paper, SWRC a silt...

Capacity-based indicators of soil physical quality (SPQ) and pore distribution parameters were proposed to assess the effects compost amendment but their determination was limited desorption water retention experiments. This study also considered size obtained from adsorption experiments establish effectiveness in modifying hydrological attributes a sandy loam soil. Repacked samples with differ...

soil water retention curve (swrc) is important in the studies of soil and water relationship, soil conservation, irrigation scheduling, drainage, solute transport, plant growth and crop water stress. the performance of 10 models (simons et al., libardy et al., campbell, farrell and larson, van genuchten, brooks and corey, driessen, exponential bruce-luxmore, power bruce-luxmore, and rogowski) w...

We investigated the effects of grade retention in first grade on the growth of the Woodcock-Johnson broad mathematics and reading scores over three years using linear growth curve modeling on an academically at-risk sample. A large sample (n=784) of first grade children who were at risk for retention was initially identified based on low literacy scores. Scores representing propensity for reten...

Bimodal soils with aggregates present a complex micro-structural and volumetric behaviour. This occurs because they showcase several variables, such as mineralogical, different grain sizes structures. The objective of this paper is to develop methodology for producing simple, non-mineralogical variability controlled double porosity. In sense, using Kaolin were created obtain bimodal samples. pr...
