Living Shorelines & Resilience in Southern California: A Summary of a Series of Workshops held as part of The Resilient Coastlines Project of Greater San Diego

In 2016, a series of workshops were held to discuss living shorelines in SouthernCalifornia. The workshops specifically focused on the unique benefits, challenges andopportunities for implementing living shorelines in the region, and the nexus betweennature-based solutions and ongoing local adaptation planning. Approximately 140participants partook in these dialogues, and some of the key themes that emergedinclude: Letting nature do the work for you Designing for the future Integrating nature into shoreline management projects Project goals distinguishing living shorelines Engineering and urban living shorelines Space constraints along urban coastlines Permitting pathways to support demonstration projects Living shorelines and phased sea level rise planning Designing with watersheds and sediment management in mind Exploring emerging commercial opportunities Public access and project success Planning for living shorelines alongside the community Sharing monitoring and best practices to ensure future success Citizen science and socio-ecological monitoringThe workshops provided the first ever opportunity for Southern California stakeholdersto outline what is unique about designing living shorelines in the context of SouthernCalifornia shorelines for state and federal entities

Tracking non-native vertebrate species: Indicator design for the United States of America

Basic information on the distribution, spread and impacts of non-native species in the USA is not available to those who shape national environmental policy. Although the USA spends billions of dollars annually on introduced species research, monitoring and control efforts, only a limited number of government agencies or private institutions are able to provide definitive reports on more than a handful of these species at a national scale. Research on invasive species is only of marginal practical value if the information cannot be succinctly and effectively transmitted to those who determine the management policies, budgets and objectives. To remedy this situation, a national-scale approach for monitoring established non-native species has been developed under the auspices of the Heinz Center as part of \u27The State of the Nation\u27s Ecosystems\u27 project. This paper specifically describes the strategies for reporting on indicators for non-native vertebrate species developed through inputs by experts from academia, industry, environmental organisations and government. © CSIRO 2008

Satellite monitoring for coastal dynamic adaptation policy pathways

Dynamic adaptation policy pathways provide a roadmap for coastal communities to establish a suite of sea level rise adaptation responses based on observation-driven signals of increasing risk. This adaptation approach relies heavily on iterative assessment of sea level rise observations and model projections. Remote sensing capabilities from satellites offer an opportunity to assess a consistent set of observational data indicators, around which adaptation pathways can be built. The large-scale nature and broad coverage of satellite observations provide the benefit of consistent monitoring capabilities across the globe, for regions with differing needs, resources, and monitoring capacities. In this study, we identify four categories of data indicators that can be monitored with satellites to support decision making in adaptation pathways: sea level rise, individual processes contributing to sea level rise, impacts of sea level rise, and impacts on implemented adaptation strategies. We review these categories in relation to existing adaptation pathway signposts and the available satellite data. As we highlight the opportunities for satellite-based contributions to sea level adaptation pathways, we also outline potential limitations, opportunities to overcome these limitations, and future steps that can be taken to integrate satellite observations into adaptation pathways

An early warning system for wave-driven coastal flooding at Imperial Beach, CA

AbstractWaves overtop berms and seawalls along the shoreline of Imperial Beach (IB), CA when energetic winter swell and high tide coincide. These intermittent, few-hour long events flood low-lying areas and pose a growing inundation risk as sea levels rise. To support city flood response and management, an IB flood warning system was developed. Total water level (TWL) forecasts combine predictions of tides and sea-level anomalies with wave runup estimates based on incident wave forecasts and the nonlinear wave model SWASH. In contrast to widely used empirical runup formulas that rely on significant wave height and peak period, and use only a foreshore slope for bathymetry, the SWASH model incorporates spectral incident wave forcing and uses the cross-shore depth profile. TWL forecasts using a SWASH emulator demonstrate skill several days in advance. Observations set TWL thresholds for minor and moderate flooding. The specific wave and water level conditions that lead to flooding, and key contributors to TWL uncertainty, are identified. TWL forecast skill is reduced by errors in the incident wave forecast and the one-dimensional runup model, and lack of information of variable beach morphology (e.g., protective sand berms can erode during storms). Model errors are largest for the most extreme events. Without mitigation, projected sea-level rise will substantially increase the duration and severity of street flooding. Application of the warning system approach to other locations requires incident wave hindcasts and forecasts, numerical simulation of the runup associated with local storms and beach morphology, and model calibration with flood observations
