Welsh Water Funds £100,000 Natural Flood Management Project in Yazor Brook Catchment

In-Depth Analysis

## Understanding Natural Flood Management (NFM)

Natural Flood Management utilizes natural processes to manage flood risk. Instead of relying solely on hard engineering, NFM works with nature to slow the flow of water through landscapes and reduce the volume entering rivers during heavy rainfall. This project, part of Herefordshire Wildlife Trust's 'Wye Adapt to Climate Change' initiative, focuses on the Yazor Brook catchment.

## Interventions in Yazor Brook

The £100,000 funding will enable the implementation of various NFM interventions tailored to the catchment:

• **Leaky Dams:** Permeable barriers made from natural materials (like branches) installed across streams slow down water flow.
• **Water Retention:** Creating shallow pools (scrapes) and ponds helps hold water back within the landscape, reducing runoff speed.
• **Hedgerow Planting:** Planting hedges, especially across slopes, intercepts surface water flow and traps sediment.
• **Tree Planting:** Trees absorb significant amounts of water through their roots, reducing surface water runoff.
• **Grassland Establishment:** Permanent pastures and meadows with diverse wildflowers have deep root systems that improve water infiltration into the soil and enhance surface water absorption.

## Broader Impacts: Beyond Flood Control

While reducing flood risk for downstream communities is a primary goal, these NFM techniques offer wider environmental benefits:

• **Drought Resilience:** Improved soil water infiltration helps replenish groundwater stores, crucial during dry periods. Diverse grasslands are also more drought-resistant.
• **Habitat Creation:** Ponds benefit amphibians and invertebrates; hedgerows provide corridors and nesting sites for mammals and birds; diverse grasslands support pollinators and other wildlife.
• **Water Quality:** Techniques like hedgerow planting help reduce sediment runoff into streams.

As highlighted by Sarah King, Nature Recovery Manager at Herefordshire Wildlife Trust, this funding facilitates tangible landscape changes that "help reduce flood risk and improve the health of the river whilst providing new and improved habitats for a range of wildlife."

Sharon Ellwood, Head of Environmental Services at Welsh Water, emphasized their commitment to enhancing biodiversity and communities, stating they look forward to seeing the climate resilience improvements.
