In this study we propose an uspcaling approach to derive time series of (a) REW scale state variables, and (b) effective REW scale soil hydraulic functions to test and parameterise models based on the REW approach. To this end we employed a physically based hydrological model, that represents the typical patterns and structures in the study catchment, and has previously been shown to reproduce ...

-Compaction is one of the efficient ways to improve the strength and stiffness properties of soils, such as elasticity modulus and shear modulus. Moreover, compaction decreases soil settlement, improves bearing capacity and the stability of sloped embankments. An optimum water content is required to provide the best path to enter energy into soil and compact it. A constant value of energy appli...

The majority of hydraulic processes under a natural condition in a field are carried out under unsaturated flow conditions. The soil moisture retention curve (SMRC) is the most important hydraulic characteristic of an unsaturated soil whose knowledge is of prime importance in soil-water studies such as soil conservation, soil erosion, land evaluation, soil reclamation, and water resources manag...

The evaluation of soil-water characteristic curve is one the most important procedures in matter understanding soil behaviour during wetting and drying processes. Even though it might be carried out by established methods, this practice considered a time-consuming technique, because still under-used comparison with its potential applications. In way, paper aims to analyse correlation suction re...

Abstract Collapsible soils are almost found in unsaturated states and involved significant engineering problems. Geotechnical challenges of such represented by the hydro-mechanical behaviour during wetting–drying cycles due to humidity climate conditions. The main objective this paper is investigate soil–water characteristic curve (SWCC) collapsible soils. In study, three types were investigate...

The macroporosity, and to a lesser extent the microporosity, of swelling and shrinking soils is affected by their shrinkage behaviour. The magnitude of the changes in bulk volume in response to changes in water content is usually described by the soil shrinkage characteristic curve (SSCC), i.e. the relation between the void ratio and the moisture ratio. At present, many techniques have been des...
