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 ...
The performance of three artificial neural network (NN) methods for combining simulated river flows, based on three different neural network structures, are compared. These network structures are; the simple neural network ...
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 ...
The multi-layer feed-forward neural network (MLFFNN) is applied in the context of river flow forecast combination, where a number of rainfall-runoff models are used simultaneously to produce an overall combined river flow ...
As part of a large EPA-funded research project, coordinated by TEAGASC, the Centre for Water Resources Research at UCD reviewed the available distributed physically based catchment models with a potential for use in ...
Recent extensive water quality surveys in Ireland revealed that diffuse phosphorus (P) pollution originating from agricultural land and transported by runoff and subsurface flows is the primary cause of the deterioration ...
This paper describes an experiment in which 2 independently developed bridge weigh-in-motion (WIM) systems are tested and compared, both for accuracy and durability. The systems, an Irish prototype still under development ...
Questions about the economic and environmental sustainability of current waste management scenarios in Europe for various organic wastes, the policy drive at the EU, and the subsequent adoption of EU policy at national ...
Step-feeding strategies have been extensively studied and comprehensively analyzed in this study for a four-stage alum sludge-based tidal flow constructed wetlands (AlS-TFCWs) system. Enhanced total nitrogen removal of 83% ...
Alternative conditioning of aluminium-based drinking water treatment sludge using Fenton reagent (Fe2+/H2O2) was examined in this study. Focuses were placed on effectiveness and factors to affect such novel application of ...
For the purpose of synthesizing a compendium of efforts aimed at environmental pollution control through the use of constructed wetlands systems (CWs) in Ireland, a detailed review of CWs was undertaken. Emphasis was placed ...
This study investigated an important issue of aluminium (Al) release in a novel reuse of Al-based water treatment sludge (Al-WTS) in constructed wetland system (CWs) as alternative substrate for wastewater treatment. Al-WTS ...
Till date, virtually all known drinking water processing systems generate an enormous amount of residual sludge, and what else to do with this rapidly increasing 'waste' stream in an economic and environmentally sustainable ...
Quantifying uncertainty in flood forecasting is a difficult task, given the multiple and strongly nonlinear
model components involved in such a system. Much effort has been and is being invested in
the quest of dealing ...
Since the September 11, 2001 terrorist attacks in the United States (U.S.), there has been a marked increase in both public and private sector demand for increased blast-mitigation for existing buildings. To adequately ...
Tackling the problem of eutrophication in fresh waters is at the top of the agenda for the implementation of the Water Framework Directive (WFD) in Europe. The problem is caused primarily by an increase in phosphorus loading ...
This paper describes the simulation of free-flowing traffic across bridges to predict
the characteristic values for bridge load effects such as bending moment and shear
force. The results of these simulations are then ...
Simple numerical models of point loads are used to represent single and multiple vehicle events on two-lane bridges with a good road profile. While such models are insufficiently complex to calculate dynamic amplification ...
This paper describes a multi-qualitative study undertaken to examine the issue of critical thinking as a graduate attribute. Critical thinking is a graduate attribute that many courses claim to produce in students. However, ...
Offshore piles are subjected to complex loading regimes, which include both rapidly
applied static and cyclic loads. This note describes an experimental investigation
conducted in order to assess the factors influencing ...
