Grain size variability on a rip-channeled beach
Marine Geology, 2011Abstract Grain size is an important variable when predicting beach morphodynamics. Beaches, to the eye, seem relatively uniform in grain size and morphodynamic modeling efforts usually assume a single mean grain size for an entire beach environment. Therefore, estimating grain size is traditionally done by collecting only a few samples and averaging ...

Machine learning applications in detecting rip channels from images
Applied Soft Computing, 2019Abstract Images containing rip channels are used in oceanographic studies and can be preprocessed for these studies by identifying which regions of the image contain rip channels. For thousands of images, this process can become cumbersome. In recent years, object detection has become a successful approach for identifying regions of an image.

Bryophytes as a special mesohabitat for meiofauna in a rip‐rapped channel
River Research and Applications, 2002AbstractRock rip‐rap is commonly used by river engineers for bank stabilization. However, there is a general lack of information on invertebrate communities inhabiting these structures. This study examines the permanent and temporary meiofauna dwelling in dense clumps of an aquatic moss Fontinalis antipyretica growing on rock rip‐rap along a side ...

Geomorphology, 2015
Abstract Rip currents are a hazard to bathers on surf beaches worldwide, yet due to logistical and ethical concerns there has been minimal examination of how bathers caught in them should attempt to escape. This study presents the first numerical model of simulated bathers escaping from a rip current.

Rip current and channel detection using surfcams and optical flow
Shore & Beach, 2022Rip currents are a common, naturally occurring surf-zone hazard that pose a risk to beach patrons. This study presents a remote-sensing-based algorithm to detect rip currents and rip channels. Optical flow-based computer vision methods are implemented to analyze large data sets and the automatic detection of these features.
