Video estimation of subaerial beach profiles

A New Video and Digital Camera System for Studies of the Dynamics of Microtopographic Features on Tidal Flats

“…This kind of digital imagery has been applied in coastal research for some years with the aim of studying changes in beach profiles and foreshore topography (e.g. Holman et al 1991, Holland and Holman 1997, Lippmann and Holman 1989, but there are few examples from intertidal flats (Ansell 1995, Røy et al 2002, Sun et al 1993). An intertidal flat is characterized by a recurrent change between inundations at high water and aerial exposure at low water once to twice per 24 hours depending on the tidal frequency (Andersen 2001).…”

Accuracy evaluation of a smartphone-based technology for coastal monitoring

“…Various changes may be observed over the long-term, which is another advantage. The technique has been used for shoreline studies where changes may be frequent and numerous [24,25,37,44,47,49].…”

Behavior and identification of ephemeral sand dunes at the backshore zone using video images

“…With these images, it is possible to study nearshore processes (Holman et al 1991) and to identify and describe important geomorphological features that are found at the beach, such as sandbars morphologies (Holland andHolman 1997, Lippmann andHolman 1990), intertidal beach profiles (Plant and Holman 1997), subaerial beach profiles (Holman et al 1991), and beach cusps (Holland 1998). This paper will use Argus image for the first time to track and monitor ephemeral dune changes over space and time.…”
