Statistical distribution of swash maxima on natural beaches

Creator:: Holland, K. Todd
Abstract:: Beach response to overwash processes is a topic of significant importance. Two particular aspects of this topic were chosen for detailed analysis: the distribution of maximum wave runup elevations and the cross-beach celerity gradient of overwash bores on natural beaches. Data were collected using both traditional nearshore instrumentation and recently...

Ocean wavenumber estimation from wave-resolving time series imagery

Creator:: Plant, Nathaniel G., Holland, K. Todd, and Haller, Merrick C.
Abstract:: We review several approaches that have been used to estimate ocean surface gravity wavenumbers from wave-resolving remotely sensed image sequences. Two fundamentally different approaches that utilize these data exist. A power spectral density approach identifies wavenumbers where image intensity variance is maximized. Alternatively, a cross-spectral correlation approach identifies wavenumbers where...

A dynamical attractor governs beach response to storms

Creator:: Plant, Nathaniel G., Holland, K. Todd, and Holman, Robert A.
Abstract:: Sandbars are ubiquitous, yet not well understood beach features that change their position and shape in response to changing wave conditions. We propose and test a simple empirical model consisting of two coupled linear differential equations that represents bar dynamics in terms of wave forcing and two other state variables:...

The Impact of Noisy Catch Data on Estimates of Efficient Output Derived from DEA and Stochastic Frontier Models: A Monte Carlo Comparison

Creator:: Lee, S. Todd and Holland, Daniel
Abstract:: There is currently much national and international interest in measuring commercial fishing capacity. Two quantitative methods that will likely be used for this purpose are data envelopment analysis (DEA) and stochastic frontier (SF) production functions. Although both methods can be used to estimate a production frontier, their underlying assumptions and...

cBathy: A robust algorithm for estimating nearshore bathymetry

Creator:: Holman, Rob, Plant, Nathaniel, and Holland, Todd
Abstract:: A three-part algorithm is described and tested to provide robust bathymetry maps based solely on long time series observations of surface wave motions. The first phase consists of frequency-dependent characterization of the wave field in which dominant frequencies are estimated by Fourier transform while corresponding wave numbers are derived from...

The statistical distribution of swash maxima on natural beaches

Creator:: Holland, K. T. and Holman, Robert A.
Abstract:: Cartwright and Longuet-Higgins (1956) describe the statistical distribution of maxima that would result from the linear superposition of random, Gaussian waves. The distribution function depends solely upon the relative width of the power spectrum and root-mean-square value of the process time series. Runup field data from three experiments are presented...

Wavenumber-frequency structure of infragravity swash motions

Creator:: Holland, K. T. and Holman, Robert A.
Abstract:: Alongshore-separated time series of natural swash motions were obtained over a range of environmental conditions using a video technique. Although the frequency spectra and normalized wavenumber spectra for these motions were particularly bland, wavenumber-frequency spectra of these data showed clear partitions of infragravity band energy levels associated with various wave...

Species, Space, and Time: A Quarter-Century of Fishers’ Diversification Strategies on the US West Coast

Creator:: Abbott, Joshua K., Sakai, Yutaro, and Holland, Daniel S.
Abstract:: In the absence of formal insurance, fishers often ”self-insure” against financial risk due to environmental and economic factors by adjusting fishing activities over species, space, and time. This diversification can be effective (e.g., Kasperski and Holland, 2013; Cline, Schindler, and Hilborn, 2017; Sethi, Dalton, and Hilborn, 2012; Fuller et al.,...
