Abstract:
... Prediction of subsurface flow (SF) in hillslopes is more complicated than prediction of surface flow; hence, a simple and practical SF model would interest hydrogeologists. For the first time, the time-area method is employed to estimate the SF of hillslopes. The locations of the isochrone curves for complex hillslopes were determined using SF travel-time equations. Some equations were developed t ...

The treatments included low (100°C, LT), medium (300°C, MT) and high (600°C, HT), heating t ...

... The Green–Ampt (GA) model, which assumes a rectangular saturated piston flow and homogeneous isotropic soil with uniform initial water content, is one of the most widely used models for describing infiltration processes. However, these assumptions severely limit the applications of the model. Thus, a modified GA model has long been a topic of interest. This study mainly investigates the effects of ...
