Book Description
"This interim guide to quantitative risk assessment for UK reservoirs provides a tool for the management of reservoir safety by experienced dam professionals. It comprises a screening level assessment of the risk of failure of a dam, i.e. the uncontrolled sudden large release of water from the reservoir it retains." "The guide is in the form of a Microsoft Excel workbook with proforma calculations, and accompanying text. It is intended to form part of either a periodic safety review or a portfolio risk assessment, where application of this guide identifies potential concerns a more detailed assessment is likely to be appropriate."--Résumé de l'éditeur.

Book Description
A new culvert inspection rating system was developed by the Ohio Department of Transportation (ODOT) and described in their 2003 Culvert Inspection Manual. The Ohio Research Institute for Transportation and the Environment (ORITE) developed a proposed rating system and tested it and the ODOT system on 60 culverts in 8 of 12 ODOT Districts across the state: 25 concrete culverts, 25 metal culverts, and 10 thermoplastic pipe culverts. The ODOT rating system rates 16 items on a 0 to 9 point scale, while the proposed system considers 30-33 items on the same 0 to 9 point scale.

Book Description
The road transport subsector tends to be vulnerable to risks. This is due to large budgets that often comprise a sizable percentage of a country's national budget (20%-30%), an unclear strategic vision, nontransparent policy decisions that lead to inappropriate priorities, procurement contracts for goods and services that lend themselves to corruption, and political interference. Additional factors include weak business processes and control systems, weak capacity of subsector agencies, and fragile links across agencies and stakeholders. This guidance note aims to explain key features of the road transport subsector and identify entry points for mapping governance risks.

Book Description
Drainage infrastructure systems (culvert, storm sewer, outfall and related drainage elements) are mostly buried underground and are in need of special attention in terms of proactive/preventive asset management strategy. Drainage infrastructure systems represent an integral portion of roadway assets that routinely require inspection, maintenance, repair and renewal. Further challenges are the wide geospatial distribution of these infrastructure assets and environmental exposure. There has been considerable research conducted on culverts, but mostly looked at the problem from a traditional structural/geotechnical perspective. Asset management procedures for culverts and drainage infrastructure systems are complex issues, and can benefit a great deal from an optimal asset management program that draws from programs pertaining to buried pipes. The first and most important step in an asset management initiative is the establishment of mechanism for asset inventory and asset conditions in a format compatible with the routine procedures of field operators and inspectors. The first objective of this research project was to develop field protocols and operational business rules for inventory data collection and management and inspection of drainage infrastructures in terms of types of data to be collected, frequency of inspection, and analysis and reporting mechanisms. After review of these protocols by the project oversight committee, a pilot study was conducted to verify efficiency of their implementation. The condition assessment protocol introduced is useful in evaluating the overall condition of culverts and can be used for decision making regarding the repair, renewal or replacement of culverts. For the second objective of this project, investigators examined the inventory and inspection protocols employed by Ohio Department of Transportation (ODOT) and developed a decision support platform, which establishes a link between the inspection results and appropriate repair, renewal and replacement procedures. After applying the recommended procedures, the transportation agencies can better track the conditions of culverts thereby reducing the risks of culvert failures.

Book Description
This volume presents the proceedings of the 18th International Probabilistic Workshop (IPW), which was held in Guimarães, Portugal in May 2021. Probabilistic methods are currently of crucial importance for research and developments in the field of engineering, which face challenges presented by new materials and technologies and rapidly changing societal needs and values. Contemporary needs related to, for example, performance-based design, service-life design, life-cycle analysis, product optimization, assessment of existing structures and structural robustness give rise to new developments as well as accurate and practically applicable probabilistic and statistical engineering methods to support these developments. These proceedings are a valuable resource for anyone interested in contemporary developments in the field of probabilistic engineering applications.
