Natural Flood Management Natural Flood Management (NFM) involves increasing the ability of land to soak up and store water so that it runs more slowly into our rivers. In addition to reducing the threat of flooding to homes and property, this work also has great benefits to rivers and their environments. NFM reduces the ferocity and frequency of extreme high river levels. Just as importantly, it helps to sustain flows during extreme dry periods such as those endured in July and August last year. By reducing the amount of rainfall flowing directly into rivers, which often comes with soil particles and chemicals, NFM will also be important in reducing the agricultural pollution affecting many of our rivers. The Foundation has started four projects that will increase the water holding capacity of land. Read more about NFM and this work in our recent e-news.
