Review of methods to measure short time scale sediment accumulation

Abstract

This review paper aims at providing a list of methods available to measure sediment accumulation in underwater or intertidal environments over short-term periods (in the order of hours to months at the most), both in situ and under laboratory conditions. Methods are classified based on two criteria: (a) whether they measure sediment accumulation or sediment elevation change and (b) whether they allow continuous or discontinuous measurements. The main characteristics of each method are outlined, along with its vertical resolution, its accuracy, its temporal resolution, its spatial coverage capacity, and an indication of its relative cost. Typical examples of applications are also provided. The purpose of this review is to be a starting point for readers who need an overview of existing techniques that measure short-term sediment accumulation, in order to guide and facilitate, for instance, the selection of an appropriate technique for a given application with set requirements.
