Bozmaps conducted a detailed flood risk analysis for Burnham-on-Crouch, a coastal town in the Maldon District of Essex, UK, using a custom-built QGIS Graphical Modeler. The aim was to visualize flood-prone areas, assess vulnerabilities across the built environment, and identify opportunities for resilience planning.

Objectives

  • Identify residential and commercial properties at risk of flooding

  • Assess land use patterns across flood-prone zones

  • Highlight opportunities for flood mitigation and infrastructure upgrades

  • Demonstrate the power of automated GIS workflows using open data and QGIS

Impact & Applications

  • Emergency planning

  • Urban resilience strategies

  • Policy recommendations for flood mitigation

  • Local awareness and stakeholder engagement

Key Findings

  • Several residential zones lie within high-risk flood areas

  • Critical commercial sites and services are located within medium-risk zones

  • One notable business, perched on elevated ground just south of Burnham, remains unaffected by even high-risk scenarios — a natural example of smart siting
