Although a lull in the storms, more expected over the coming week, the water levels in The Thames have been rising by the hour, and are expected to continue rising throughout the week.

Today, in Berkshire and Surrey, fourteen severe flood warnings on The Thames. There are also two severe flood warnings in the Somerset Levels.

A severe flood warning is when there is risk to life.

Politicians are playing the blame game, though they have backed off today.

We are still hearing calls for dredging of rivers.

Rivers are dredged and canalised for navigation, not flood management. A river that is allowed to meander, form ox bow lakes, overflow into the flood plain, carries more water, than one that has been dredged.

If were are to point fingers of blame, then it has to be at the politicians.

  • they have failed on climate change
  • they have cut money for flood management
  • they have not spent money wisely

The current floods are due to the exceptional rainfall that has fallen since earlier January.

We have to rewild, re-afforest upstream, re-introduce wolves, lynx and beavers, possibly wild boar, retain water upstream.

Beavers create small pools upstream, slw the flow rate, provide cleaner water, enhance wildlife habitats, increase the number of fish.

Records are available for the Wye Valley since 1936. For seventy years, little change in rainfall, a tripling of the incidence of flooding. Over that period, grubbing up of trees, over-grazing of sheep (both paid for and enforced by EU). Since the late 1990s, there has been a policy of Let Sleeping Logs Lie, of not clearing the streams of fallen woodland debris.

Pickering used to flood, the streams were dredged. Now, trees are toppled over into the streams.

The Pontbren Project, a group of farmers in Wales, took it upon themselves, to re-afforest their land. Instead of grubbing out trees, they are planting shelter belts to be used by the sheep. Instead of expensive straw bedding for the sheep, wood chippings. The bedding then used for compost to grow more trees, a closed cycle. Instead of draining boggy patches, creating ponds.

When the water sheets off the land, it gets as far as the trees, then vanishes, sucked down into the ground by the trees. Land covered in trees will absorb 67 times the water, as land covered in grass.

If only 5% of the land at Pontbren were re-afforested, flooding peaks downstream would be reduced by about 30%. Full reforestation would reduce the peaks by about 50%.

For the residents of Shrewsbury, Gloucester and the other towns experiencing flooding by the Severn, were the catchment areas re-afforested, they would probably not be flooded today.

We know from the tropics, cut down trees, those living downstream get flooded. Why have we not learnt those lessons?

The River Wey, starting to flood Guildford last Friday, running very high through Farnham last Saturday, eventually finds it way into The Thames.

Flood management is not the river, flood management is the area that drains into the river.

The sun is shining, the snow is melting, the daffodils are out, it is marginally above zero.

The first week of spring.

The cold winter weather is projected to continue for the next 2-3 weeks.

A walk in a Siberian wilderness

January 16, 2013

A walk in a Siberian wilderness or at least that is what it felt like. The trees were white, but not white with snow they were white with frost from the freezing fog, the fields white with fallen snow.

I took the same walk as yesterday, only this time I went to the end of the country lane. could have carried on as the muddy tracks no frozen or will be with a few more days of subzero temperature, but I was feeling tired, it was late afternoon and the light was fading I decided to turn around and head back.

Snowy day

Sunday there was a sprinkling of snow. By lunchtime it had gone.

4am this morning, everywhere white. By around mid-morning, roads clear, but everywhere else a thick covering of snow.

Lunchtime a second wave of snow swept in which lasted until dusk. Big snowflakes came fluttering down.

I decided not to venture out, temperature barely above freezing.

Hard frost at midday

Midday, and yet cold hard frost.

I went out lunchtime. Only a few minutes down the road, I was frozen, my feet were cold. Ten minutes later, my head was throbbing with the cold.

Twenty minutes later, I was at a railway station waiting for a train.

From the train window, everywhere white with frost. It was as though I was travelling through Siberia.

Only last night, I had been discussing Aleph, travelling on the Trans-Siberian Railway.

End of November, beginning of December, cold hard frost in the morning.

Yesterday at the farmers market in Guildford it was very cold, with a cold wind blowing. I was glad to be indoors as it was getting dark. It turned very cold during the night.

This morning it was white. I thought frost but no, a light sprinkling of snow. The first snow of the winter.

Not far away, heavy snow, airports and roads closed.
