Measuring Soil Infiltration to improve parameters for Stormflow Modelling for Different Land uses 🌿 At Babbage Consultants Limited, teams specialising in engineering, ecology, soil and environmental sciences take a multi-disciplinary approach to support our clients. From compliance monitoring and reporting or securing water supplies to solving complex stormwater challenges, we deliver tailored solutions across the country and abroad. Our Latest Project: As part of a comprehensive soil assessment, we conducted infiltration testing using double-ring infiltrometry. Complementing full soil descriptions including soil texture, structure, voids and coarse fragment and root distribution this helps us understand soil physical properties and assess the impact of land-use changes, such as removing grazing cattle to promote regeneration of forest and reforestation of pastoral land. Why This Matters: - Improved Soil Health: Reforestation enhances soil aeration, microbial biodiversity, and infiltration rates. - Runoff Management: Forested areas reduce peak storm flows due to increased interception and infiltration rates. This helps in mitigating risks like erosion and eutrophication. - Data-Driven Decisions: Our findings are aimed at supporting the refinement of Runoff Curve Numbers (CN), which are currently based on SCS 1986 U.S. standards. By incorporating locally relevant data and updated land-use parameters, we can improve hydrological storm flow models. This will lead to more effective stormwater management strategies and enhanced resource efficiency, benefiting communities and the environment. This project highlights how forest regeneration and reforestation influence soil properties, runoff and erosion dynamics and the effect of this on aquatic ecosystems.
