Combining remote sensing data and an inundation model to map tidal mudflat regions and improve flood predictions: A proof of concept demonstration in Cook Inlet, Alaska

Abstract: [1] Accurate flood predictions require high resolution inundation numerical models and detailed coastal and land topography data. However, such data are not always available. A new method to obtain topographic information of flood zones from remote sensing data is demonstrated here for Cook Inlet, Alaska, where tidal range reaches 8 -10 m. The moving shoreline is detected from analysis of water coverage in satellite images taken at different tidal stages, and then the shoreline data from different times are co… Show more

“…Comprehensive sensitivity experiments (∼30 different runs) with a newly developed WAD scheme, WAD-POM, implemented in a widely used three-dimensional community ocean circulation model (Oey 2005(Oey , 2006Oey et al 2007;Ezer et al 2008;Ezer and Liu 2009), have been conducted in order to study tidal-driven mixing processes in the coastal environment. Model calculations are compared with a control model without the WAD scheme.…”

“…The details of the combined WAD-POM numerical model and recent applications can be found in Oey (2005Oey ( , 2006, Oey et al (2007), Ezer et al (2008), and Ezer and Liu (2009). An idealized exposed seamount (i.e., an island), with the maximum depth approximately 50 m, is used in this study; a mean sea level (MSL) is set to be 20 m below the maximum allowable sea level (Fig.…”

“…The primary difference between the method of Horritt et al [14] and Chaouch et al [15] is the former computes the inundation extent as a vector feature (line) using a statistical active contour model where the latter computes a raster representation of cells as wet or dry. In addition to using active sensors such as SAR, passive optical sensors such as MODIS and Landsat have also been used to identify inundated areas [18,19]. In this paper, the approach of Chaouch et al [15], herein referred to as the "synergetic method", is used to validate a tidal model.…”

“…For example, Ezer and Liu (2009) compared the topography data currently available for the CI inundation model (Oey et al 2007) with Landsat remote sensing data, demonstrating the much greater details that the remote sensing data can provide. So how can one use remote sensing data to study morphology and climatic changes, as well as improve flood prediction models?…”
