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.

Fine news for beekeepers today – a total ban on bee-harming pesticides has been announced! To celebrate, here is a list of plants we recommend as being brilliant for the bees: Helenium Sedum Echium vulgare Marjoram or Oregano Eupatorium (common name? Joe Pye-Weed. But don’t let that put you off!) Borage Nepeta Veronicastrum Teucrium Bonus plants for shady spots? Try hellebore, lamium and pulmonaria. Looking for a shrub to plant near your apiary? Phillyrea ought to do it. Although it is difficult to get hold of…. we are working on making it more available though, so check back with Modern …
Hey Modern Minters, we have been busy already this year – so busy! Here is some of the topiary work we love doing so much…. A post shared by ModernMint (@modernmintshop) on Apr 5, 2018 at 9:48am PDT Whilst evenings (and some afternoons!) have been spent travelling the country giving garden talks to clubs, horticultural societies, WI’s and U3A’s. This is all fabulous fun but it has meant: We have not been consistent with our mailing list I have not finished the book ‘Helping The Honeybee’ I was due to get to the publisher by the end of February There …
This week I gave a talk – Helping The Honeybee – to the lovely beekeeping group at Southend on Sea. Here are some notes for those who didn’t have a chance to write down some of the ideas we spoke about and shared…. The Top Plants For Bees Helenium Sedum Echium Marjoram (which you will find in your seedballs) Oregano Eupatorium, also known as Joe Pye-Weed Borage Nepeta Veronicaastrum Teucrium Phillyrea If you want a hedge for around your apiary, you will not go too far wrong with planting the amazing, tough as old boots, Phillyrea.
