1 Monitoring coastal bank in Western Port Bay Dr Kerrie Tomkins and Gordon McLachlan CSIRO Land and Water
2 Lang Lang shoreline Western Port Bay
3 Problem: sediment input into WPB through coastal bank Knowns: The banks are a major source of sediment: estimated ~ 32 % Estimates of rates of retreat from air photos: ~ 0.5 m/yr
4 Problem: sediment input into WPB through coastal bank Unknowns: Howfast are the banks eroding? Is there variability in rates of over time and space? How reasonable are previous estimates: in the ball-park? over-est? under-est? How much sediment is going into the bay through bank? What are the processes and conditions leading to? What are the options for reducing sediment inputs into WPB?
5 Additional key research questions: Whenis occurring? E.g. What is the role of storm events and tidesin triggering, and reworking or removing eroded material? Whyare the banks eroding? E.g. What is the morphology, sedimentologyand alsusceptibilityof the banks? How do changes in pore water pressure associated with the semi-diurnal tidal cycle and groundwater seepageimpact on the likelihood of failure? Are other factors such as wave energy andorientation of the shorelinerelative to the windwave direction important?
6 1888 Dept of Lands Yallock Parish Map 2012 GPS survey Important points about this site: Actively eroding prior to human disturbance The gross morphology of the coastline has changed very little since 1800 s
7 1947 1:15,840 air photos 2010 NearMap air photos 1916 sea wall clearing and drainage channels 48 m Changes in last ~60 yrs: headlands more rounded and crenulations less pronounced Well documented history of human disturbance Significant disturbance response in drainage channels Limited direct impact on shoreline, except revetment
8 Methods Selected study site small crenulation, which is typical of the coastline Measuring rates using surveys and 100 pins Using other information: air photos, DEMs Observational analyses of processes GPS surveys (start& end) Erosion pins (measured ~6-7 wks)
9 1 3 2 Analysing sediments Recording tide and storm conditions Measuring wind speed and direction Measuring tide height and groundwater levels Weather station 4 Sedimentary and geomorphic units 5 Tide gauge Monitoring camera Groundwater piezometer 2.5 m

20 What do we know so far? Slowest rates are at the apex of the crenulation Fastest are at the headlands Steeply sloping surfaces are eroding the fastest i.e. bench face and upper & lower banks Horizontal surfaces are eroding the slowest Sedimentology: Lowest units stable; Upper units slightly dispersive, but not always inundated during tides Observed physical processes of abrasion and detachment, rather than slumping or dispersing All These represent background rates for the last 4-5 months under the tidal cycle What don t we know? What happens during storms? Do these patterns change? Only 1 storm so far on 4-5 Dec and no greater impact observed.
21 Further work: Continued measurement of the pins Use pin rates and DEM to estimate sediment yields Also undertake an end-of-study GPS survey = before/after Assess the role of large storm events over winter (hopefully) Assess the role of groundwater Investigate the role of shoreline orientation, fetch, wind speed and direction and make some calculations of wave energy Contribute to WPB hydrodynamic modelling Consider other areas how representative are our results? Make some recommendations for reducing bank
22 Conclusions Since monitoring commenced on 1 November 2012, we have measuredaverage bank rates in the order of 3 cm/ month, although someparts of the banks are eroding much faster at > 10 cm / month. These rates are relatively consistent with previous estimates. The 3 cm monthly averagerepresentsa background rate of under the normal tidal cycle, aided by wind-generated waves. Storm events may also be important but we ve only had one major storm-tide event within the monitoring period to date was it major enough? Erosion is predominantlyoccurring through thephysical processes of abrasion and detachment of sediment from the bank surface = the problem is wave energy. Thecohesive andresistant nature of the sedimentsforming the banksappear to beplaying a key role in limiting despiteconditions of semi-diurnal wave attack. Future managementoptions mayinclude structures aimed atreducing wave energy on the banks. Target areas may be the headlands(?) but it s too early to call on what and where. Further work should provide a lot more insights!
