Free-surface behaviour of shallow turbulent flows

Over the last two decades, interest in free-surface behaviour of gravity-driven shallow turbulent flows has increased considerably. It is believed that observation can provide useful information about hydrodynamic characteristics flow and enable remote retrieval these to non-invasively rapidly monitor river flows. At current state literature presents scattered knowledge also exhibits non-uniformity terminology used. This paper a review state-of-art this area research was created with objectives: gather relevant understand linkages between underpinning processes while using uniform terminology, analyse gaps our critical topic.
