Pipeline capacity results derived from any hydraulic models are heavily dependent on several assumptions including ambient ground temperature and heat transfer. This paper presents a simplified approach to identify and validate ambient soil temperatures along with determining the heat transfer coefficient to be utilized in transient hydraulic models. The proposed method entails linear regression and statistical analysis of empirical ground temperature data, as well as utilization of parametric modeling techniques to adjust heat transfer coefficients by comparing results with SCADA data.
