When north Wales was flooded, many acres it was catastrophic for several reasons.
It's sea water not fresh so the ground is affected,/poisoned. crops lost, wildlife lost. Cattle, sheep, drowned. Vehicles written off fear of corrosion.
The area was flooded for weeks.
Homes had a four foot tidal line. Those homes when the water eventually recede have to be treated for sewage contamination. Then in go the dehumidifiers. We had dehumidifiers hired by contractors from all over the country. This lasted for two years Families in hotels, rentals, holiday camps for up to a year.
There's obviously a shortage of contractors in a disaster which makes the whole restoration painfully slow.
Drains exploded, so roads dug up to replace them.
Elderly people actually died in the interim so never saw their homes again.
Anyone with a dinghy was asked to assist in rescuing people stuck in their homes including my husband, he was getting people out of windows and rowing them to safety.
Water is actually worse long term than wind
