The characteristics of unsaturated soil seen from the Groundwater Characteristics Curve (SWCC). One main variables determine SWCC are Air Entry Value (AEV). AEV is initial point air entering void. was obtained fitting model Soil Vision. Although statistically a can match laboratory result, resulted different curve shaped by points. Therefore, this study aims to understand further influence on p...

Abstract Unsaturated permeabilities of six different kaolin-sand mixtures named as 100K0S, 90K10S, 80K20S, 50K50S, 20K80S, and 10K90S were directly measured using a modified flexible wall triaxial permeameter system. 90K10S means that the soil mixture contains 90% kaolin 10% sand by dry mass. Soil–water characteristic curves (SWCC) also for wide range suctions Tempe pressure cell, 5-bar plate, ...

Rainwater infiltration is primarily governed by the soil-water characteristic curve (SWCC) and hydraulic conductivity function (HCF) of soil. Both SWCC HCF are hysteretic during drying wetting processes. In a numerical simulation, different seepage results can be obtained incorporating functions practice, commonly estimated from using statistical method, which named HCFswcc,w in this note. Howe...

The knowledge of the continuous evolution soil hydraulic characteristics is required for several environmental geotechnical applications such as capillary barrier systems and river bank slope stability analysis. Such data are obtained in field by embedding suction sensors slopes equilibrium time other limitations establishing not available compacted soils. Thus influence initial moisture conten...

One of the main hydraulic properties unsaturated soils is Soil-Water Characteristic Curve (SWCC). It essential to understand, predict soil water storage and determine mechanical behaviour soils. These curves can be obtained by direct indirect measurements. The measurements obtain these are expensive, delicate perform really slow for fine soils, so predictive models become necessary. In order ma...

Several structures are built on collapsible soils in the mining and petroleum industries civil sites. In order to analyze stability of such structures, one must properly study unsaturated soil behavior. Collapsible frequent sand that susceptible a significant sudden reduction volume upon wetting. An important factor is matric suction, which es related moisture content through water Characterist...

Abstract Klang Valley area is one of the most landslide-prone areas in Malaysia, especially at Hulu Kelang, Kuala Lumpur. The has been frequently hit by landslide since 1990s. Soil instability agreed researchers occurred due to high precipitation and long duration rainfall which cause property damage leading injury fatality. Slope failure also triggered antecedent leads infiltration rainwater i...

Hydraulic properties (such as soil–water characteristic curves (SWCC) and hydraulic conductivity function (HCF)) play an important role in evaluating the stability of unsaturated soil slopes. Loess soils are widely distributed Gansu Province China, most them conditions due to deep groundwater table (G.W.T). In this study, twenty-eight sets data published literature were analyzed develop upper l...

Soil water characteristic curve (SWCC) is very important in the study of unsaturated soil because it represents a soil’s ability to store and release as subjected various suctions. This storage moisture paramount irrigation engineering, determines scheduling dryland. reviews some SWCC model’s performance predict from selected soils Nigeria previous work. work contains 7 points between 0 – 1,500...
