AUS-FL14 Australia - This is a very badly built dam. It was partially protected by with vetiver - to reduce wave action damage
AUS-FL15 Australia - This is a very badly built dam. It was partially protected by with vetiver - to reduce wave action damage. Some vetiver has been planted on the wall - note the trees on the dam wall - not a good thing to have
AUS-FL16 Australia - This is a very badly built dam. It was partially protected by with vetiver - to reduce wave action damage
AUS-FL16 Australia - Note how the dam has silted up. During a storm the dam breached (arrow) in a spot where the vetiver planting had been terminated
AUS-FL17 Australia - This farm reservoir was very badly constructed. A narrow line of vetiver was planted along the top of the wall, at the time of breaching the earth wall below the vetiver was not washed out. The breach occured where the vetiver had not been planted
AUS-FL18 Australia - This farm reservoir was very badly constructed. A narrow line of vetiver was planted along the top of the wall, at the time of breaching the earth wall below the vetiver was not washed out. The breach occured where the vetiver had not been planted. Note the thick and massive vetiver root system that has prevented wash out
AUS-FL20 Australia - This farm reservoir was very badly constructed. A narrow line of vetiver was planted along the top of the wall, at the time of breaching the earth wall below the vetiver was not washed out. The breach occured where the vetiver had not been planted. Note the thick and massive vetiver root system that has prevented wash out
AUS-FL21 Australia - This farm reservoir was very badly constructed. A narrow line of vetiver was planted along the top of the wall, at the time of breaching the earth wall below the vetiver was not washed out.

AUS-FL22 Australia - This farm reservoir was very badly constructed. A narrow line of vetiver was planted along the top of the wall, at the time of breaching the earth wall below the vetiver was not washed out. The breach occured where the vetiver had not been planted. Note the thick and massive vetiver root system that has prevented wash out. Paul Truong
AUS-FL23 Australia - This farm reservoir was very badly constructed. A narrow line of vetiver was planted along the top of the wall, at the time of breaching the earth wall below the vetiver was not washed out. The breach occured where the vetiver had not been planted. Note the thick and massive vetiver root system that has prevented wash out. It is interesting to see how all the soil has been washed away from the wall except where the vetiver was planted
AUS-FL24 Australia - This farm reservoir was very badly constructed. These tree roots did not stop washout from the flood
AUS-FL25 Australia - This farm reservoir was very badly constructed. A narrow line of vetiver was planted along the top of the wall, at the time of breaching the earth wall below the vetiver was not washed out. The breach occured where the vetiver had not been planted. Note these tree roots are in a stand alone mode, all the soil being washed away. The moral of this story is that vetiver has a remarkable potential to prevent structural damage due to flooding
ZIM-FL01 Stream bank stabilization with vetiver in Zimbabwe. There is a strong flow of water 150 cusecs, flowing in this stream for days on end, sometimes if the water flow was increased it would flood and the banks would be damaged. Vetiver prove to be an effective system to prevent stream bank erosion from flooding
ZIM-FL02 Stream bank stabilization with vetiver in Zimbabwe. There is a strong flow of water 150 cusecs, flowing in this stream for days on end, sometimes if the water flow was increased it would flood and the banks would be damaged.

ZIM-FL07 A good stand of Vetiver used to stabilize the spillway of a small reservoir in Zimbabwe -
ZIM-FL08 Here the vetiver, planted in close rows across the spillway reduces the velocity and power of water passing down this spillway
ZIM-FL09 HIn this iamge water passing down the spillway has concentrated and cut back a little until it came up against vetiver roots - cut back stopped in its tracks
ZIM-FL10 water pouring through this spillway, but no erosion. Under the flow is a mat of vetiver that has been pushed down by the water forming a protective mat of leaves and roots. In the dry season there is full recovery of vetiver in this favorable microclimate
ZIM-FL11 Vetiver is providing the desired protection on this spillway
AUS-FL26. Australia's Darling Downs located in Queensland has on average a 2% slope. The farm land is subject to severe flooding and erosion. As a consequence farmers use very broad fallow strips that use 30% of the land to prevent erosion. Vetiver has been shown on these lands to be very effective against flood erosion, at the same time using less than 5% of the land. Because the land is so flat hedgerows were planted in straight lines as shown in this image. (lower left)
