A new solution satisfying Richards' equation is derived. The solution, which may be applied for infiltration or capillary rise, is valid for the condition of an arbitrary moisture tension imposed at the soil surface. When written in terms of the moisture t ...
Contaminant transport in structured soil systems is often characterised by early and asymmetric breakthrough curves. These phenomena are usually interpreted using the mobile/immobile region model, which is suitable for the simulation of nonequilibrium proc ...
The setting level of an hydraulic machine, specially for low head machines, is decided with respect to the possible alteration of the efficiency due to the cavity development. This alteration can easily be noticed by plotting the evolution of the efficienc ...

In a water wet porous medium, the antecedent moisture content controls the entrapment of LNAPL at low capillary numbers. A two-phase retention cell study of entrapment was conducted for LNAPL water systems in a carbonate sand. For two different LNAPL water ...
Hydropower plants play an important regulatory role in the large scale integration of volatile renewable energy sources into the existing power grid. This duty however requires a continuous extension of their operating range, provoking the emergence of com ...
The increment of frictional deficiency by roughening the inner wall of spiral case is extracted from the optimum specific hydraulic energy deficiencies of a model Francis turbine that was measured by changing surface roughness of the spiral case. Assuming ...

This article presents the numerical analysis of temperature increase in the human head resulting from the power dissipation in a cortical implant. A 3–D head phantom with 22 tissue types and 0.2 mm x 0.2 mm x 2 mm resolution has been used in the simulation ...
A variety of field techniques were utilized to study the immiscible displacement of LNAPL (gasoline) above a fluctuating shallow water table. Hydrophobic and hydrophillic tensiometer measurements were compared to a dual-well monitoring system that measured ...

The two-region model was developed originally to describe nonsorbing chemical transport in soils with dead-end pores based on the concept of mobile and immobile regions in the soil. It has been shown that the model can simulate solute transport in soils wi ...
