JScreen

JScreen is a tool for the prioritisation of stormwater and flooding infrastructure, assessments of blockage risks and climate change adaptation.  Combined with tools such as JFlow and FRISM, it has been developed for assessment by Councils and government (from an LGA to national scale) and transport authorities (at a route-wide scale) to identify and prioritise high risk assets now and in the future. 

JScreen is used to perform asset-specific blockage simulations.  This involves sequentially blocking flows discharging through bridge, culvert and waterway crossings, and running the high-speed JFlow hydraulic model to produce impact flood maps.  This procedure is repeated 1000’s of times to calculate the likely surcharge and overland flow pathways, flood extent, number of impacted properties and infratsutre, depth and area impacted due to blockage at all culverts.  This information can be used to undertake an economic benefit assessment, and justify ongoing maintenance programmes

It can be used to:

  • Assess large-scale flood risks at a catchment, incorporating climate change resilience planning.

  • Identify likely culvert locations across large-scale unchartered transport corridors. 

  • Undertake flood consequences assessments at an asset-level, for a range of blockage scenarios (e.g. 33%, 50%, 66% 100%), return periods and climate change scenarios.

  • Assess blockage consequences.

  • Offer a risk-based approach to the prioritisation of investment strategies and asset maintenance schedules.
