The Queensland Harbours and Marine Department is charged with the responsibility of providing small craft facilities throughout the State. In 1964, the Department engaged a firm of consulting engineers, Blain, Bremner and Williams Pty. Ltd. to prepare a preliminary report on possible boat harbour sites between Yeppoon and Port Alma on the Central Queensland Coast. Five sites were evaluated according to the following criteria:- (i) Degree of protection afforded (ii) Tidal access (iii) Degree of maintenance dredging anticipated (iv) Capital cost necessary to establish the harbour and the ability to construct the harbour in stages (v) Availability of foreshore area for development (vi) Accessibility by road transport and to established amenities (vii) Availability of suitable quarry material The recommendation that the most suitable site would be at Rosslyn Bay (Figures 1 & 2) was accepted and approval to commence construction was obtained. A 105m rubble mound rock breakwater was constructed in 1968. The breakwater was extended to 210m in 1970 and was further extended to 300m in 1972. In 1976 tropical cyclone 'David' extensively damaged the breakwater and harbour facilities. Subsequently the breakwater has been redesigned following model studies and reconstruction was completed in May 1978. This paper discusses damage to the breakwater from wave and surge action, model studies and repair of the breakwater.

The number of craft breweries and the volume of beer they produce continue to increase in the United States. Small entrepreneurial craft brewery businesses produce limited quantities of specialty beer, also known as craft beer. As of 2018 the state of Montana had the second most craft breweries per capita in the United States. In addition to competitive industry forces, legal and environmental forces are two of the most salient concerns for craft brewery businesses in Montana and throughout the United States. A case study about Montana Hop Brew, a Montana-based craft brewery, is presented. The case highlights the entrepreneurial nature of small craft breweries and describes competitive industry, legal, and environmental forces that Montana Hop Brew faces. Teaching notes complete with learning objectives, required and supplemental readings, a student exercise, and discussion questions are available to assist with delivering the case.

Different Depths

Model experiments were made to devise a rapid method for calculating magnetic anomalies of three‐dimensional structures. The magnetic fields of the models were determined using the equipment at the Naval Ordnance Laboratory, White Oaks, Md. An irregularly shaped mass was approximated by an array of prismatic rectangular slabs of constant thickness and varying horizontal dimensions. Contoured maps are being prepared for these magnetic models at different depths and for several magnetic inclinations. The fields of these three‐dimensional structures are obtained by super‐imposing the appropriate contoured maps and adding numerically the effects at each point. The equipment and laboratory methods are described. Theoretical and practical examples are given.

Defects Analysis

The article presents an analysis of the implementation of a selected element of the traveler safety system used in road transport. The results of metallographic tests were presented, and the state of stress introduced to the casting by means of forming the element by means of plastic forming was analyzed. An analysis of the manufacturing process was carried out indicating the risks that may lead to cracks in the material structure. Possible causes of founding defects were pointed out and possible technological solutions were pointed out in order to avoid them.

Ecosystems are employed to effectively protect people and communities in coastal areas from tropical cyclone (TC) hazards. Although a spatially explicit TC hazard mitigation service (TCHMS) is essential for devising adaptation strategy and resilience policy, the process and delivery of this program are unclear. We improved a capacity–exposure–demand conceptual framework using Guangdong Province, China, as a case study area, and spatial analysis was employed to assess the ecosystem service. Under this framework, we assessed “capacity” as the natural potential protection against TC hazards, “exposure” as the need for services, and “demand” as the estimated necessity of protecting coastal populations and economic interests. The analysis results were then used to map the TCHMS flow and benefit gap. The results showed that 21.6% of the whole province had low capacity, 25.3% had high exposure, and 19.3% had high demand. A significantly negative correlation was present between the TCHMS capacity and exposure, and a positive correlation was shown between the exposure and demand. In particular, the TCHMS flow and benefit were sufficient in inland areas but were severely deficient in coastal megacities. In Guangdong Province, the Pearl River Delta, and Chaoshan (CS), 3.3%, 4.0%, and 15.3% of the areas showed high demand–low capacity–high exposure patterns, respectively. Our findings will deepen the scientific understanding of the degree of protection a given ecosystem will provide to communities and infrastructures exposed to TC hazards and will thus provide scientific support for coastal ecosystem planning and management.

Transport Emissions

The European Union aims at net-zero emissions by 2050. A key sector to achieve this goal is road transport, where emissions show no signs of reducing but continue to grow. A review of policies undertaken by EU member states and the G20 to reduce transport emissions reveals that both present and planned policies focus on binding supply-side measures, but offer only weak demand-side incentives. To address this imbalance, we developed a downstream, demand-side policy prototype through an expert interview design process. We call the prototype “cap-and-surrender” because it caps road emissions, and then allocates tradable emission allowances to individual vehicles that drivers surrender at each fill-up. Allowance pricing, both by the state and in the secondary market, is designed to incentivize decarbonization of the sector. Though the system would require significant investment, its revenue potential to the state should exceed this investment by several multiples. We discuss the potential economic, environmental and social impacts of the policy, as assessed by European transport experts. We find that the approach can deliver significant transport emission reductions in an effective and economically efficient manner. Through the appropriate design of national allocation rules and a gradual phasing in of cap and surrender, potential negative social consequences can be mitigated, and public acceptance of the policy promoted.

The article presents the state of existing and future forecasts for a vehicle park equipped with fuel cells in the world. Reference has also been made to the current and future situation in the area of hydrogen refueling infrastructure in the world. The situation in the above-mentioned area in Germany is discussed, which is one of the leading countries in the hydrogenization of motor transport. A proposal for the development of hydrogen propulsion technology in Poland has been presented. In a similar scope, reference is made to the issue of electromobility in road transport, both in the world, in the EU, and in Poland.
