Although three-dimensional laser (3DLS) scanning has been used to document and monitor individual excavation walls and structures on a limited basis, impediments remain to its use for major infrastructure projects. This ...
A major landslide event occurred at Pollatomish, County Mayo, Ireland in
September 2003, during a period of intense rainfall. It comprised about 30 significant
individual longitudinal planar type slides of peat and ...
Falling trees pose a great hazard to the safe and uninterrupted use of the road transportation system, during storm events. The present process of manually identifying potentially hazardous trees is laborious and inefficient. ...
Use of microcrystalline waxes for the protection of ceramic art objects from seismic events is an inexpensive and relatively popular technique in museum exhibition practice (Fig. 1). Unfortunately, because of the high ...
The photocatalysis of natural organic matter, fulvic acid (FA), by P25 TiO2 in terms of UV254 and TOC concentrations was investigated in this study. The experiments were conducted in a lab-scale photocatalysis-ultrafiltration ...
Alum sludge refers to the by-product from the processing of drinking water in Water Treatment Works. In this study, groups of batch experiments were designed to identify the characteristics of dewatered alum sludge for ...
The adsorption characteristics of phosphate adsorption on the dewatered alum sludge were identified as a function of pH and ion strengths in solution. In addition, adsorption mechanisms were investigated by conducting batch ...
Techniques required to successfully obtain downhole block samples of typical
very soft high plasticity organic clay from Ireland are described. The vane shear strength of
the material is as low as 4 kPa. These included ...
An effective disaster management system requires collection of baseline data that is comprehensive, accurate, timely, and accessible. Without these four characteristics, an effective, economical, and task-oriented disaster ...
The grouted, helical pier system (GHPS) is proposed as an example of a capacity improvement option for existing pile foundation groups. This paper explores the relative relationships between these geotechnical elements ...
Rehabilitation of building structures is a critical need facing numerous older urban areas. Many of these structures are supported on pile groups, which do not have adequate load capacity to support the demands expected ...
Laboratory testing for foundation design offers advantages over field-testing, especially, where existing installations preclude easy accessibility. Advantages include a homogeneous soil, ability to place instrumentation ...
The effect of using coarse grain in the upper layer of a gravel-based reed bed is investigated. The aim for testing the “anti-sized” arrangement of gravel media is to seek a solution for the practical problem of medium ...
Conditioning of an alum-based water treatment sludge by single and dual polymers was investigated in this study. Capillary suction time (CST), specific resistance to filtration (SRF) and settling rate of conditioned sludge ...
This paper is a research brief highlighting the development of a novel alum sludge based constructed wetland system, aimed at reducing the pollution effects of agricultural run-offs. Alum sludge is a by-product of drinking ...
Due to increasing time, cost and transportation difficulties, Irish contractors
are seeking an alternative to conventional static pile load tests. As a result several
firms have adopted dynamic testing techniques to ...
A comparative study of the NGI Direct Simple Shear Test (DSST) and the Mikasa Direct Shear Test (DST) is reported. Samples from Norwegian Drammen clay and Japanese Ariake clay were subjected to both types of test. An ...
A one-day workshop was convened to address obstacles to success of American women
faculty in Geotechnical Engineering. The workshop, sponsored by the National Science
Foundation (NSF), was held in October 2003, in ...
