Use permeable paving for streets and sidewalks

My proposed project investigates the use of permeable paving systems for streets and sidewalks within a UK context. The focus is on evaluating their hydraulic performance, structural suitability, and contribution to climate resilience using analytical modelling and literature-based assessment. The core idea is to compare conventional impermeable asphalt pavements with permeable paving systems in terms of peak runoff reduction, storm return period performance, and long-term feasibility. The study will use hydrological modelling (Rational Method) under different rainfall return periods (e.g., 1:2, 1:30, 1:100 year storms) to quantify runoff reduction potential. Structural suitability will be assessed using published pavement design guidance rather than experimental testing. There will be no laboratory testing involved in this project. The research is designed as an analytical and modelling-based study supported by critical literature review. This decision is based on: The suitability of modelling for hydrological comparison Time and resource constraints The availability of strong published performance data The relevance of analytical evaluation to urban design practice The dissertation will therefore include: A critical literature review of permeable paving performance Hydrological modelling and sensitivity analysis Structural design assessment using published guidance Lifecycle and maintenance evaluation Critical discussion of limitations and implementation challenges I would appreciate confirmation that a modelling-based, non-laboratory dissertation is acceptable at Level 6, provided that it demonstrates sufficient depth of analysis, critical evaluation, and independent academic judgement.
