Modeling Nearshore, Barrier, Cliff, and Coastline Morphodynamics

Book section · January 1, 2022 Researchers use models to understand and forecast morphodynamic evolution in a variety of coastal contexts: surf zone dynamics including the short-term evolution of the nearshore seabed and shoreline; the longer-term evolution of coastline planview shapes, ...

Which Models Are Good (Enough), and When?

Book section · January 1, 2022 With the possible exception of some basic theories such as quantum mechanics and relativity, scientific models are by nature incorrect—at best they correspond to a natural system in limited ways. This is especially true of models used in Earth-surface-proc ... Full text Cite

Rhythmic Coastal Landforms

Book section · January 1, 2022 Coastal landforms can sometimes result in unique and visually mesmerizing spatially-organized patterns. Different spatial patterns develop over scales ranging from centimeters to tens of kilometers, and are observed at the shoreline (e.g., ripples, beach c ... Full text Cite

Morphodynamic Modeling of River-Dominated Deltas: A Review and Future Perspectives

Book section · January 1, 2022 River-dominated deltas on Earth are composed of diverse shapes and patterns, ranging from small-scale bifurcations that create channel networks to large-scale deltaic lobes that build deltaic plains. Morphodynamic feedbacks among fluid flow, sediment trans ... Full text Cite

The role of ecomorphodynamic feedbacks and landscape couplings in influencing the response of barriers to changing climate

Book section · February 15, 2018 Because barriers are low-lying and dynamic landforms, they are especially sensitive to changing environmental conditions. The continued existence of barriers will depend on the degree to which these landforms can maintain elevation above sea level while al ... Full text Cite

Geometric constraints on long-term barrier migration: From simple to surprising

Book section · February 15, 2018 Considerations of mass conservation, sediment budgets, and geometry lead to insights regarding how barriers respond to sea-level rise. We begin with relatively simple insights, which facilitate more surprising conclusions as more complicated cases are cons ... Full text Cite

Geoengineering Coastlines? From Accidental to Intentional

Book section · June 10, 2015 On developed coastlines, humans react to physical processes in coastal environments by stabilizing shorelines against chronic erosion and by taking measures to prevent destruction of coastal infrastructure during storms. While we are beginning to understan ... Full text Cite

Riparian Vegetation as a Primary Control on Channel Characteristics in Multi-Thread Rivers

Book section · March 19, 2013 While many previous studies have explored the effects of vegetation on single-thread rivers, systematic studies on multi-thread rivers are scarce. Our approach is to synthesize data and ideas from a field-based study of the Waitaki River in New Zealand wit ... Full text Cite

Two paradigms in landscape dynamics: Self-similar processes and emergence

Book section · September 25, 2007 This volume is comprised of the proceedings of "20 Years of Nonlinear Dynamics in Geosciences", held June 11-16, 2006 in Rhodes, Greece as part of the Aegean Conferences. ... Cite

Rip currents due to wave-current interaction

Book section · January 1, 2005 In this linear instability study, we examine the incipience of depth averaged circulations, which are related to rip currents in the surf zone, due to interactions of waves and currents on alongshore uniform beaches. We consider normally incident waves, su ... Full text Cite
