MSIT Workshop, Buck's Group: How is each process relevant to sediment management and tidal marsh restoration actions? by Matt Ferner https://padlet.com/mferner/ozhandpyu09u90nq en-us 2021-04-15 21:25:12 UTC 2021-04-27 17:47:42 UTC hello@padlet.com how does putting coarse sediment on top of mudflats affect transport of fines on to marsh? https://padlet.com/mferner/ozhandpyu09u90nq/wish/1434391266 2021-04-19 17:45:01 UTC https://padlet.com/mferner/ozhandpyu09u90nq/wish/1434391266 Also, sediment deposition in mudflats. In other words, do we have a good understanding where sediment supply for mudflats is coming from. Is it deep water channels or fluvial inputs. xavierfernandez7 https://padlet.com/mferner/ozhandpyu09u90nq/wish/1434391787 2021-04-19 17:45:06 UTC https://padlet.com/mferner/ozhandpyu09u90nq/wish/1434391787 understanding mudflat erosion and accretion rates (in addition to marsh edge erosion) https://padlet.com/mferner/ozhandpyu09u90nq/wish/1434392692 2021-04-19 17:45:16 UTC https://padlet.com/mferner/ozhandpyu09u90nq/wish/1434392692 how does creek size, morphology, etc affect sed flux? https://padlet.com/mferner/ozhandpyu09u90nq/wish/1434393522 2021-04-19 17:45:25 UTC https://padlet.com/mferner/ozhandpyu09u90nq/wish/1434393522 is there a point with tidal creek scour stops and transport off of the marsh declines https://padlet.com/mferner/ozhandpyu09u90nq/wish/1434394815 2021-04-19 17:45:40 UTC https://padlet.com/mferner/ozhandpyu09u90nq/wish/1434394815 How do we figure out the balance of sediment supply across a marsh edge vs supply via tidal creeks on different types of marshes? https://padlet.com/mferner/ozhandpyu09u90nq/wish/1434394923 2021-04-19 17:45:42 UTC https://padlet.com/mferner/ozhandpyu09u90nq/wish/1434394923 How can offshore living shoreline reefs enhance mudflat and marsh sedimentation? https://padlet.com/mferner/ozhandpyu09u90nq/wish/1434395262 2021-04-19 17:45:45 UTC https://padlet.com/mferner/ozhandpyu09u90nq/wish/1434395262 how does marsh edge morphology differences in vegetation at the edge change wave dampening https://padlet.com/mferner/ozhandpyu09u90nq/wish/1434398667 2021-04-19 17:46:14 UTC https://padlet.com/mferner/ozhandpyu09u90nq/wish/1434398667 does the offshore living shoreline dampen waves enough such that sediment ends up in the mudflat and not on the marsh https://padlet.com/mferner/ozhandpyu09u90nq/wish/1434400244 2021-04-19 17:46:31 UTC https://padlet.com/mferner/ozhandpyu09u90nq/wish/1434400244 How do we monitor sediment redistribution in large marshes to see how much sed coming across the marsh edge or from the tidal creek makes it out to the middle and upper portions of the marsh? https://padlet.com/mferner/ozhandpyu09u90nq/wish/1434400500 2021-04-19 17:46:34 UTC https://padlet.com/mferner/ozhandpyu09u90nq/wish/1434400500 effectiveness and approaches for mudflat augmentation (beneficial reuse) https://padlet.com/mferner/ozhandpyu09u90nq/wish/1434401646 2021-04-19 17:46:45 UTC https://padlet.com/mferner/ozhandpyu09u90nq/wish/1434401646 How can we use these findings to help maximize effectiveness of mudflat augmentation or shallow water placement of fine material https://padlet.com/mferner/ozhandpyu09u90nq/wish/1434402799
