Hydrodynamic Modeling of Coastal Flooding
LA402L utilized the USGS Coastal Storm Modeling System (CoSMoS) 3rd generation hydrodynamic models for Southern California to identify areas at risk for inundation and interpolated the timeline in consultation with Dr. Juliette Hart.
Earlier sea level models were static state, so didn’t factor in the significant contribution of waves to coastal flooding, above and beyond the levels observed by the tidal gauges. Interesting to note that the predicted sea levels are higher than the current tsunami risk zone delineation.

Over ten weeks in the winter of 2017, sixteen BSLA students my LA402L Advanced Landscape Architecture Studio at California State Polytechnic University, in collaboration with AHBE Landscape Architects (Los Angeles), developed site-specific strategies and tactics to assist the City of Long Beach’s efforts to plan for sea level rise (SLR).
Sea Level Rise strategies and tactics identified by the students of LA402L provide a range of short term mitigation tactics of the impacts and/or long-term adaptation opportunities for the community and waterfront. These strategies and tactics can be categorized as:
Centralized: defined by top-down policies or regulations, neighborhood or community-wide deployment, and reliance on public funding to implement.
Decentralized: implementable by individual property owners and occupants to protect a single building, parcel, or block. These strategies and tactics may require changes to the zoning or building code, and/or innovative construction approaches.
Together with the mitigation and adaptation strategies and tactics (below), the matrix of Decentralized/Centralized and Mitigation/Adaptation is abbreviated as “DCxMA”. Continue reading
Excited to share that AHBE Landscape Architects is sponsoring my winter 2017 402L studio! This 4th year BSLA topic studio will develop strategies and tactics for the waterfront of Long Beach and communities along the Lower Los Angeles River to adapt to rising sea levels, urban flooding, and tsunamis. From tactics to schematics, projects will develop site-specific soft infrastructure typologies suitable for wide-scale deployment around Southern California to sustain our ports and vibrant waterfronts.

Our field investigations will take us to Long Beach and out onto San Pedro Bay to explore the interface between water and land (the bravely curious students may need to take Dramamine).
Infrascape readers will be able to follow the students’ progress via their blog posts to http://ahbelab.com.
Stay tuned for updates!
