In this paper, we propose a multi-commodity, discrete kinematic wave model for simulating network traffic flow that possesses the theoretical rigor and computational efficiency inherent in the kinematic wave theory. In this model, 1Author for correspondence (Current address: Institute of Transportation Studies / University of California / 522 Social Science Tower / Irvine, CA 92697-3600 / (949)...

The Water Erosion Prediction Project (WEPP) model is a process-based, continuous-simulation, watershed hydrology and erosion model. It is an important tool for water erosion simulation owing to its unique functionality in representing diverse landuse and management conditions. Its applicability is limited to relatively small watersheds since its current version does not simulate flow in permane...

The significant effect of waves on coastal and marine activities urges the precise identification of wave characteristics using field measurements, theoretical studies, physical modeling or numerical simulations. In order to study thoroughly the wave climate in the Caspian Sea, a wave modeling and hindcast project was performed by Iranian National Center for Oceanography. In this study, one of ...

Animals like the sandfish lizard (Scincus scincus) that live in desert sand locomote on and within a granular medium whose resistance to intrusion is dominated by frictional forces. Recent kinematic studies revealed that the sandfish utilizes a wave of body undulation during swimming. Models predict that a particular combination of wave amplitude and wavelength yields maximum speed for a given ...
