Hydraulic Capacity of Bend Manholes for Supercritical Flow

Report Cards for Manholes

We present a manhole profiling tool, developed as part of the Columbia/Con Edison machine learning project on manhole event prediction, and discuss its role in evaluating our machine learning model in three important ways: elimination of outliers, elimination of falsely predictive features, and assessment of the quality of the model. The model produces a ranked list of tens of thousands of manh...

A pulsatile developing flow in a bend

Low frequency pulsatile flow of an incompressible viscous fluid has been numerically investigated in a rigid 90° bend of circular cross-section, using the finite-volume method. The governing parameters are as follows : amplitude ratio of 1.25, Womersley

An Improved Methodology for Measurement of Uninterrupted – Flow Capacity Affected by Pavement Condition

The present Serviceability Rating (PSR) is one of the major criteria in selecting road for rehabilitation. In this paper, statistically realistic models for are developed PSR and free speed correlation on uninterrupted flow facilities. Then, the previously developed relations between free speed and capacity are used to determine the effect of pavement condition on flow capacity. Two nearly iden...
