	Bi-monthly conventional topographic surveys of part of one bank were undertaken by MoLA in 1999 and 2000 allowing for decadal scale assessment of the erosion. High resolution aerial photographs and digitized historical Ordnance Survey maps are available dating back to at least the 1930s and these will be used to assess changes in surface area and any migration of the banks generally. We have engaged with the local community and formed partnerships with other commercial, charitable, academic and volunteer organisations including Thames21, the River Restoration Centre, Leica Geosystems, DHI, MoLA, and Royal Holloway University of London.

	\|Monitoring surveys and results=Very accurate baseline surveys have been completed.Preliminary assessment indicates a current rate of retreat of the banks at around 1m per decade, or approximately 10cm annually.A large amount of material has accumulated behind the spiling and facines which are being well maintained. Additional work, installation of supporting posts and fascines, has commenced on the east side of the island.		\|Monitoring surveys and results=Very accurate baseline surveys have been completed.

	\|Lessons learn=Restoration work using traditional willow withies has resulted in improved overall appearance and accretion to some areas of the bank. Vegetation is not growing in the silt perhaps because of a lack of oxygen. Seepage from the bank toe area is keeping the silt mobile in some areas. The current approach employed by Thames21 of incremental maintenance appears to be successful and demonstrates good cost vs. benefit, especially since partners have started to make contributions towards costs. Withies planted on the flat surface of the island by the Old Chiswick Protection Society are growing well and the willow holt, which is pollarded annually, appears to be in good condition. The withies produced by the pollarding are bundled by the OCPS and volunteers and used to provide structure behind the spiling and fascines.		\|Lessons learn=Restoration work using traditional willow withies has resulted in improved overall appearance and accretion to some areas of the bank.

	It might be useful at this point to consider additional techniques such as rolls of rocks (rocks bundled into mesh 'socks') at the areas of the bank toe with seepage. Thames21 has also mentioned using different species of aquatic plants.
