Coastal Management and Economic Development in Developed Nations: The Forth Estuary Forum

This article considers the issue of economic development as a component of coastal management initiatives in developed countries, focusing on the Forth Estuary Forum as a case study. The evolution of coastal management into integrated coastal management is briefly considered, as is the context of the Scottish coastal management system and a brief discussion of the variations between the different legal systems within the UK. The current hurdles to economic development and the views of developers and economic agencies being considered in the coastal management process itself are highlighted, illustrating the process of integration and the current voluntary regime in the UK, particularly in the Forth Estuary Forum. The article concludes that economic development issues must be taken seriously if coastal management is to be integrated and inclusive.

Dynamic response of the non-contact underwater explosions on naval equipment

Shock resistance capacity of the shipboard equipment especially for large ones, has been a strong concern of navies all over the world for a long time. The shipboard equipment have previously generally been studied separate from hull structure before. In this paper the coupling elastic effect between equipment and hull structure is taken into account. With the ABAQUS software, the integrated model of the equipment coupled with the hull structure is established to study the dynamic response of the shipboard equipment to the shock wave load as well as the bubble pulsation load. In order to verify the numerical method, the simulated results are compared to the experimental data, which are from a specific underwater explosion on an actual ship. On this basis, by changing the charge location, attack angle, equipment installation location and other parameters, the characteristics of dynamic response under different conditions can be obtained. In addition, the results of the integrated calculation and the non-integrated one are compared and the characteristic parameters which affect the equipment shock response are analyzed. Some curves and conclusions are obtained for engineering applications, which provides some insights into the shock resistance of shipboard equipment.     

A framework for travel time variability analysis using urban traffic incident data

This study aims to develop a framework to estimate travel time variability caused by traffic incidents using integrated traffic, road geometry, incident, and weather data. We develop a series of robust regression models based on the data from a stretch in California's highway system during a two-year period. The models estimate highway clearance time and percent changes in speed for both downstream and upstream sections of the incident bottleneck. The results indicate that highway shoulder and lane width factor adversely impact downstream highway clearance time. Next, travel time variability is estimated based on the proposed speed change models. The results of the split-sample validation show the effectiveness of the proposed models in estimating the travel time variability. Application of the model is examined using a micro-simulation, which demonstrates that equipping travelers with the estimated travel time variability in case of an incident can improve the total travel time by almost 60%. The contribution of this research is to bring several datasets together, which can be advantageous to Traffic Incident Management.
