Windfarms and flooding
12:46pm Friday 15th June 2012 in Letters
The severe flooding around Talybont, north of Aberystwyth, featured on the BBC TV national news on Saturday June 9th will become a regular occurrence in future if the Nant y Moch wind farm goes ahead.
The River Leri which flows through the currently flooded villages of Dolybont and Talybont before crossing the western edge of Borth Bog to reach the sea at the Dyfi Estuary, rises in the high peatlands surrounding Nant y Moch Reservoir on the western flank of Pumlumon mountain.
This is precisely the area where the Welsh Assembly Government [WAG] plans to erect 60 gargantuan 475 ft wind turbines, under its TAN 8 proposals. The turbines' vast concrete bases and wide supply roads will replace the present highly absorbent peat and moorland , clearly resulting in regular flash floods downstream whenever there is far less rain than at present. Imagine the size of the non-absorbent concrete platforms and wide roads required by 60 structures almost as tall as Blackpool Tower !! The run-off of rainwater will be immediate !
Even worse, the River Rheidol and its tributaries rise in Nant y Moch before reaching the sea at Aberystwyth. They can expect regular flooding in Aberystwyth too.
It does not even end there; the concreting and tarmacing of vast areas of peatland and forest in the huge catchment areas of the mighty Wye and Severn, east of Pumlumon for yet another TAN 8 zone ,covering many square miles, will undoubtedly cause regular flash flooding in places like Builth Wells, Hay-on-Wye, Welshpool, Shrewsbury, Gloucester and Hereford.
Furthermore, what about the villages below the Clocaenog Forest area of Denbighshire in a third TAN 8 zone ? What happens when forest is replaced by concrete and tarmac? There will undoubtedly be flash floods there too.
Further south , the creation of the huge Pen y Cymoedd wind farm in the South Wales Valleys , with all its constituent concrete platforms and wide roads is bound to cause flash floods in the densely populated Valleys.
Then on Sunday June 10th, there were flood warnings regarding the River Teifi at Llanybydder. Yet there are plans to build a huge TAN 8 wind farm nearby on Mynydd Llanllwni, within the catchment of the River Teifi. Again there will be rapid run-off and flash flooding.
TAN 8 is going to cause flash flood disasters all over Wales and the Welsh Marches . The metalling of absorbent moorland and forestry areas within the catchment areas of our major rivers is on an unprecedented scale.It has not even been considered by our Welsh Assembly Government . The warnings,this week, are absolutely stark !!
Don't forget ! This is June .....the driest time of year !!. What will happen when it turns really wet from Autumn through Winter to Spring? Have WAG , the Environment Agency and County Councils even considered this massive future problem as they meddle with nature on a gargantuan scale in our Welsh hills? All they are concerned about is carrying out "green "policies !
They must be very "green" indeed if they can't see what's coming !!
