Technical difficulties and innovation in the Jiangyin Yangtze River crossing project of 3300 m HDD

open access: yesNatural Gas Industry B, 2014
The Jiangyin Yangtze River Crossing Project sets up a record with the length of horizontal directional drilling (HDD) of 3300 m in the world. Inevitably, many technical difficulties might exist in pilot hole docking, reaming torque, property requirement ...

New perspectives on horizontal to vertical well ratios for site cleanup

open access: yesRemediation Journal, Volume 30, Issue 1, Page 27-31, Winter 2019., 2019
Abstract Directional drilling has been used for a variety of purposes, including utilities, dewatering, and remedial activities. Using this method for site cleanup versus traditional vertical extraction wells needs to be considered based upon today's remedial challenges. Traditionally, it has been stated that a single horizontal well can substitute for

Application of Digital Image Cross Correlation to Study Sinkhole Collapse

open access: yesInternational Scholarly Research Notices, Volume 2013, Issue 1, 2013., 2013
This paper presents the results of a study using a transparent soil experimental technique and numerical modeling to detect 3D deformations resulting from submerged cavities that lead to a sinkhole. Excessive deformations from underground activity beneath highway pavements could lead to sinkhole collapse. The formation of a sinkhole is often sudden and

Quantifying Interannual Variations in Groundwater Fluxes Within a Braidplain Aquifer Using Active‐Distributed Temperature Sensing

open access: yesWater Resources Research, Volume 61, Issue 7, July 2025.
Abstract Braided rivers are a significant contributor to groundwater flow in braidplain aquifer (BPA) systems, yet the spatiotemporal variations in flow exchange remain poorly understood. This study presents an extensive active‐distributed temperature sensing data set collected over a 3‐year period from two 100‐m long fiber optic cables installed up to
