Overland Spread and Hydrographic Flow Modeling for Pipeline Integrity Management Track: Pipeline Transmission Author(s): Steve Parris, Tracy Thorleifson Utilizing the ArcGIS Spatial Analyst extension, an advanced Overland Spread and Hydrographic Transport spill modeling solution for pipeline "could affect" segment identification and, risk quantification has been developed. Techniques used closely model real world impacts of hydrocarbon releases by accounting for dynamic flow conditions resulting from topographic variation, product evaporation, adhesion and infiltration. The solution includes network topology in drain down calculations, extensive incorporation of product properties (density, viscosity, temperature, vapor pressure, etc.) into all calculations, and accurately predicts behavior of Highly Volatile Liquids (HVLs). The modeling engine accommodates channelized flow, lateral spread, and hydrographic transport modes. A temporal linear referencing scheme is used to facilitate modeling of release trajectories through time. For each sample point and its intersected High Consequence Areas (HCAs), a wealth of calculated data is recorded. This information is utilized to formulate risk mitigation scenarios such as Electronic Flow Restriction Device (EFRD) placement and risk consequence analysis.
