Abstract: Salt marsh elevation and geomorphic stability depends on mineral sedimentation. Many Mediterraneanclimate salt marshes along southern California, USA coast import sediment during El Niño storm events, but sediment fluxes and mechanisms during dry weather are potentially important for marsh stability. We calculated tidal creek sediment fluxes within a highly modified, sediment-starved, 1.5-km 2 salt marsh (Seal Beach) and a less modified 1-km 2 marsh (Mugu) with fluvial sediment supply. We measured salt marsh p… Show more

“…In the tidal marsh on Browns Island in Suisun Bay (up-estuary of San Pablo Bay), hSSFi during an October spring tide was also negative, although at that site advective SSF was positive and the bayward flux during the spring tides was dominated by dispersive flux (Ganju et al, 2005). In contrast, at Mugu Lagoon, a southern California tidal marsh, maximum landward hSSFi was measured during large spring tides, primarily due to an increase in positive advective SSF (Rosencranz et al, 2016). Enright et al (2013) also observed strong landward tidally averaged water flux (sediment flux was not measured) during spring tides in the brackish First Mallard marsh within Suisun Marsh (San Francisco estuary).…”

“…Fagherazzi and Priestas (2010) observed similar negative advective SSF during large ebbs produced by meteorologically enhanced low tides in a marsh on the Gulf of Mexico. In Seal Beach marsh in southern California, a storm produced bayward advective SSF, but the total hSSFi was landward due to a large increase in positive dispersive SSF during the storm (Rosencranz et al, 2016).…”

“…Few studies employed rigorous sediment flux measurement methods; Suk et al (1999) was one of the first to methodically account for tidal-to-annual timescale sediment fluxes in a salt marsh channel. Subsequent studies (Ganju et al 2005;Rosencranz et al 2016) further established the concept of using sediment budgets as integrative metrics to diagnose salt marsh vulnerability in an analogous framework to Fagherazzi et al (2013). Specifically, a marsh complex that is exporting sediment must be unstable, whether due to marsh plain disintegration, edge erosion, or channel export; while a marsh complex that is importing sediment at a rate sufficient to match sea level rise may be stable and maintaining its lateral and vertical position or expanding.…”

“…While the spatial scale of the restoration project is limited, placing it in the context of the overall sediment regime is important to understand the cumulative impact of multiple small-scale projects that may be undertaken in the future. Conversely, at Seal Beach National Wildlife Refuge, where thin-layer placement has been performed (Thorne et al in review), pre-and postplacement sediment fluxes are nearly neutral (Rosencranz et al 2016;Thorne et al in review), suggesting that any sediment placement would not be offset by losses elsewhere in the system under present conditions. Additionally, the environmental settings of these two regions are very different: Blackwater is in a largely undeveloped area, while Seal Beach is completely constrained by urban and residential development.…”

“…POM fluxes were estimated for tidal channels within eight marshes on the east and west coasts of the United States ( Figure 1). Complete details of the field campaigns are described by Ganju et al (2013), Montgomery et al (2015), Rosencranz et al (2016), Suk et al (1999) and Suttles et al (2016). All sites are tidal salt marsh complexes drained by a primary tidal channel, with maximum tidal ranges varying from 0.30 to 2.5 m ( Table 1).…”
