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.

We now have everything back in stock on the pruning tools front – hurray! Take a look at what you might like for doing any cutting and clipping this Autumn…. Also, please note the following: We Are Away From Wednesday 12th September, Until Thursday 20th September, So No Orders Will Be Sent Out During This Time! Is that ok? If you do make an order and then realise we won’t be sending it out, then we will send you a refund when we get back. Just let us know via email what you prefer. Otherwise, we will send out the …
Sorry to people asking for some of our pruning tools, but we have run out of a few items and are waiting for more to arrive. I did a number of garden talks this week and demonstrated the quality of some of the tools. This led to a run which I hadn’t anticipated! So apologies again if you are missing out, but everything should be back in stock by next week. Many thanks for all your support here at Modern Mint! Darren
A brand new garden talk for 2019? My, what exciting news! Having had a busy summer, with the topiary work exploding after the Guardian article, I have plans to write a new garden talk for next year. So far I have written 6 different talks in the 4 years I have been running Modern Mint, 4 of which are still available for you to book. They are: What Do I Do With This Space? A garden talk that looks at how other cultures treat their outdoor spaces. A mixture of funny stories and practical advice, it shares techniques people from …
