'There could be more to come' - experts warn of more landslips in Bournemouth after recent storms

THERE could be more landslips in the coming days and weeks, experts warn.

On Thursday night, a shock 170ft landslip occured between Bournemouth and Boscombe piers, blocking off the promenade all day on Friday.

Following the clean-up operation on the beach, the geo-technical expert assessed the cliffs east of Bournemouth Pier to make sure they were safe.

Mr Saunders said: “A geo-technical expert has studied the cliff face and determined that all the debris has now fallen away with no further danger of a landslide.

“A small amount of lose material, however, may fall when it next rains, forecast for Sunday.

“We have been advised that a section of the cliff adjacent to where the landslip occurred does need monitoring over the next few days and therefore the surrounding promenade in that area will stay closed until further notice.”

Doctor Mark Cowley, a chartered engineering geologist, a leading landslide expert, said: “The landslip is likely to be as a result of all the recent wet weather.”

He said the rainwater would have percolated into the sands that appear to make up the slope, and as it does so the overall strength of the soil that make up the slope has been reduced.

“There is always likely to be some water in the slope but as the extra water flows into it after heavy rain, it cannot drain away very quickly and the soils become what we call fully saturated,” he said.

“In effect the groundwater table rises up within the slope and the ability of the slope to remain stable at its current angle is diminished.”

Dr Cowley, who has 25 years’ experience in this field, said that slopes such as the east cliff in Bournemouth can fail after the heavy rain has occurred.

He added: “There are likely to be more slips in saturated slopes in the coming days and weeks as the groundwater levels rise after a very wet winter.

“They are not usually a major problem as they are often only fairly minor.

“However people need to be vigilant and be aware of the potential danger that a large slip like this can present.”

I suggest supporting the cliffs with several miles of ugly green netting and thousands of large metal props. Like at Castlepoint*

"There could be more landslips in the coming days and weeks". Thanks for that.
It's like the weather forecast saying "50% chance of rain".

Close the beaches for at least a year it's the safest bet. Imagine if all that came down on people walking on the prom when the air show is on in the summer. The jet noise from the Vulcan could bring massive sections down !

Can another 'expert' be employed to tell us whether the sun will shine or whether it will rain on a Sunday in three weeks time?

They should also add shrubbery to bind the soil. Some time ago an idiot in the council had the bright idea to remove a lot of the vegetation at the top!

Going to have to face the cliffs now with reinforced concrete, its the only way to make them safe.

Over here in Thailand when the land on the hills get deforested and no trees are replanted there are no roots to hold the soil together and so when it rains they get landslides and mudslides. The rivers get blocked and floods occur which is what seems to have happened with the cliff fall but without the resultant floods.
It has been happening for millions of years and in years gone by folklore was kept bt the older people and passed down the generations. Now we have experts who are paid to tell us what many people think is just common sense.
Don't build a house there as my old granddad told me it floods often sort of thing.

The Vulcan would actually have to turn up for a change for that to happen.

I am always amazed at these so called experts who come out with the blindingly obvious, and to think that these experts are paid vast sums of money, if he could talk my pet hamster could have arrived at the same conclusion.

No danger there then, the Vulcan never gets off the ground so we should all be pretty safe.

"There could be more to come" and yet today's article states "Councillor Lawrence Williams, cabinet member for tourism, said they had no fear of other slips along the cliffs, and that the beach was “perfectly safe”.

Well which on is it guys? Better call the so called expert again.
