study of the spatial variability of infiltration characteristics is essential to estimating infiltration parameters on a local scale. the objectives of the present study were to scale the parameters of a philip two-term model for infiltration and survey the variability of infiltration characteristics geostatistically using wastewater in the bajgah catchment. infiltration was measured at 30 poin...

Abstract The tendency of cementitious systems to absorb and transmit liquid through capillary pores is often characterized by initial sorptivity, which an important indicator long-term durability. However, sorptivity measurements, are based on the continuous mass change specimens exposed water, labor-intensive (up 6 h measurements). Here, we exploit fundamental surface-wetting characteristics e...

Concrete durability, especially in water-logged environments might not be possible with conventional constituents of concrete. A combination mineral and chemical admixtures different proportions is used to study water absorption, sorptivity, permeability behavior The test were carried out using nine (9) trial mixes Calcined Clay (CC), Sawdust Ash (SDA), Crystalline Based Admixture (CBA), Superp...

Analytical solutions of the flow equation for infiltration offer an interesting tool for the hydrodynamic characterization of non-saturated soils by optimization of the hydraulic conductivity, Kfs, and the capillary sorptivity, So. However, the experimental conditions have to satisfy the governing assumptions. For falling head infiltration tests the initial water height, Ho, is a third unknown ...
