HISTORICAL SPATIAL-TEMPORAL EVOLUTION AND MORPHODYNAMICS OF BLOWOUTS IN CAPE COD NATIONAL SEASHORE
The STAMP method allows for pattern-based detection, quantification, and visualization of changes that occur through time and space. Erosional deflation basins – the concave portion of blowouts - are easily identified and digitized from photographic coverage and STAMP detects changes in basin morphology by analyzing polygon dynamics against neighboring polygon layers and extracting spatio-temporal patterns of movement and geometric change. From this, observed patterns of blowout morphodynamics (e.g. expansion, contraction, stabilization, generation, disappearance, and migration) at CCNS are analyzed and modeled. Examination of this sub-population of features of varying size and (presumably) stages of evolution, allows for classification of common morphodynamic responses and development of an initial model of blowout evolution.
