Effective water resources management typically relies on numerical models to analyze groundwater flow and solute transport processes. Since the important hydrogeological parameters of these models (e.g., hydraulic conductivity) ...

Water shortages and flooding have caused large property losses and endangered human lives in many areas. Rapid and informed response is needed to ensure effective water management, including reliable and immediate data ...

This research has demonstrated that, while abiotic perchlorate removal by GAC is ineffective, BAC filtration can provide efficient, sustained perchlorate removal under a broad range of operating conditions and water quality ...

This project focused on the abrasion resistance of concrete railway crossties. In the first phase of this project, a series of high performance concrete mixes was developed that utilized different replacement levels of ...

An accelerated testing procedure was developed to evaluate performance of separation layers used between open-graded bases and lime stabilized subgrades. Significantly of concern was assessing separation layer performance ...

Recent developments in photogrammetric methods, in general, and orthophoto mapping in particular, have resulted in the increasing availability of digital elevation data. The accuracy of digital elevation data generated ...

This investigation focuses on the study of acoustoelastic effects on Rayleigh surface waves (R-waves) in concrete samples subjected to 4-point load bending and uniaxial compression, considering a broad range of strain ...

The methodology developed three major design aspects: a genetic algorithm-based control parameter optimization based on the real design criteria, a state space reconstruction technique for estimating the full state of a ...

This report summarizes the tasks and findings of the ICT Project R27-163, Adapting Construction Staking to Modern Technology, which aims to develop written procedures for the use of modern technologies (such as GPS and ...
