Incident response workers from Natural Resources Wales are carrying out emergency work at two beaches in Pembrokeshire to reduce flood risk after the storm last weekend.
Following the high tides and gale force winds which hit west Wales on Saturday evening, shale and sand has been pushed up the beach blocking outfalls on beaches at Amroth and Newgale.
The outfalls allow water to flow onto the beach at low tide reducing the level of the Trelissey Stream at Amroth and Brandy Brook at Newgale.
As the culverts are now blocked, river levels will gradually rise and could cause flooding of local properties, a caravan park and roads.
The specialist teams will be on site over the next few days to remove over 3000 tonnes of shale from both sites and allow the river levels to return to normal.
This work is especially important as the weather continues to be unsettled over the winter months.
Neil Davies, from Natural Resources Wales, said: “After severe weather we saw over the weekend, it is vital to make sure that any blockages or obstructions are cleared as soon as possible.
“We were on standby over the weekend, checking our flood defences and responding to any issues with our assets, and now we are making sure that any damage to them is fixed.
“If anyone sees any blockages or damage they are concerned about we urge them to call our incident hotline on 0800 80 70 60 so we can respond or liaise with other agencies to address the problem.”
This week marks the start of a month-long national campaign to raise awareness and provide advice on flood risk.
