To prevent future flooding there is a need to manage the land in a different way. The dredging of rivers will do nothing but speed up the flow of water to ‘pinch points’ further upstream. The use of sandbags is a measure provided too late, when normal life has been halted by water flowing into homes.
Natural Flood Management (or NFM’s) must now be considered a major part of flood prevention. The critical factor of NFM measures? The planting of trees to slow down running water.
By planting trees near headwaters they act as a buffer to hold up rainwater runoff. Planting woodlands near streams works in exactly the same way, slowing down the water. Debris from the trees can also fall into the river, creating dams that hold back excess water. These ‘timber flow interventions’ can even be man-made, by laying fallen tree trunks into the stream. These are far cheaper measures than building bigger walls to protect towns.
Trees also help water percolate into the soil (60 times faster in some research) although infiltration will be reduced if the land is already saturated. If this is the case, what options do we have then? Short-term, we are back to the sandbags. Long-term though, we lessen rainwater runoff rates from poorly managed land. How do we do that?
Treat our soil better.
We could stop winter sowing of crops. This leaves the soil bare for months. With nothing to bind it together it turns into mud when wet and leads to land erosion. The sowing of a winter ground cover would benefit the soil as much as preventing flood damage.
Stop compacting the soil with heavy machinery and too many animals walking over it. Compacted land works the same as any impermeable surface – it cannot take the water, so the water must just run off and down streets and into homes.
Add organic matter to the soils. They will hold more water, yet won’t become waterlogged.
Is there anything else we can do?
Don’t build houses on floodplains. This may alleviate housing shortages in the short-term, giving whichever Government bragging rights over what they have achieved while in power, but the problems will arrive later on… and money will still have to be spent on rebuilding, on rehousing, on healthcare for people who are having to live with stagnant water around their ankles. The costs will always catch up with us in one form or another.
Concrete and dredging are all very well – but we need to slow water down, and give it places to sit and be held when it does become to much.
We need to plant trees, we need to cherish and protect our floodplains, and we need to look after our soil.

Plastic ‘dalek’ compost bins. Peppered through the gardens in our country as a free gift from the councils. My guess is they gave out these bins because they wanted people to compost more, saving them money as they would have to take away less garden waste. Thinking to be applauded, right? But is there a design flaw in them and has it put people off making their own compost? The Great Reviews For A ‘Dalek’ Compost Bin Here is the one I mean… The ‘Dalek’ bin. They call it a compost converter online. It is made from recycled plastic, so that …
Why I Started Modern Mint I always loved working outside and especially working with trees. I still get a thrill, even now, when planting them. But it was only in 2014 when I moved from Hampshire to Essex that I began to shape and express the values I thought important enough to garden by – the ‘no chemicals’ rule, the recycling of resources, the increasing of life… My move to garden here in Essex, in the driest part of the UK, became the perfect opportunity to start again and share these ideas with people interested in the spaces and landscapes they live in. Modern Mint. The Place …
Climate change – mention it and you are guaranteed to make the discussion political. (Which probably isn’t a bad thing, as long as people are not so entrenched in their views they won’t listen to the other side…. and of course, that never happens!) We went seal watching last summer on the estuary in Essex. It was amazing, seeing these wild animals just living on the banks. The man who took the group of us out on his boat spoke about the difference he has seen on the water over the last 30 years. He believes the water level has …
