Delta Strategy Analysis

The uncertainties in how this topic affects delta restoration has resulted in its inclusion in the ESRP River Delta Adaptive Management Strategy. This three criteria analysis should build off the analysis above, and supports development of learning projects.


Importance Viability Policy Relevance

We have observed erosion of marsh disconnected from river sedimentparticles of clay, silt, sand, gravel, or cobble, transported by water, are called sediment. supply, but are unable to predict how restoration or loss of marsh affects the ability of adjacent sea dikes to limit flooding under future storm and sea level conditions.

Emperical models that describe the relationship between marsh character and wave mitigation developed at a single site, may reduce costs of analyses at future sites. An initial investment in instrumentation can lead to long term data collection that supports such models.

Identifying marsh as a component of a flood defense system may increase interest in marsh restoration and distributary reconnection.
