Abstract The development and implementation of the River Information Services (RIS) concept started in end 1990s with various research projects followed by national or regional first decade this century. resulting RIS systems haven’t been able to exploit full potential when it comes cross-border data exchange interoperability. To overcome these gaps Corridor Management was established aiming at...

This paper applies a geospatial network optimization model to explore environmental, economic, and time-of-delivery tradeoffs associated with the application of marine vessels as substitutes for heavy-duty trucks operating in the Great Lakes region. The geospatial model integrates U.S. and Canadian highway, rail, and waterway networks to create an intermodal network and characterizes this netwo...

Here we introduce a combined experimental and descriptive approach (termed resurrection ecology) to reconstructing historical perturbations, pointing out how direct tests with sediments and hatched resting eggs complement the traditional descriptive calculation of microfossil fluxes. In the Keweenaw Waterway, a freshwater estuary off Lake Superior, turn-of-the-century copper mining impacted the...

A prototype of a computerized accident risk assessment tool for freight transport in Finland has been constructed based on a concept developed in an earlier stage of the study project. The tool is based on a realistic description on the road, rail and waterway networks, and real data on traffic flows and the occurrence of injury accidents on freight transports in Finland. The estimates of accid...

Despite the growing role of barge transportation in the hinterland access of major seaports in Northwestern Europe, service network design for intermodal barge transportation has received little research attention. In this paper, a decision support model for service network design in intermodal barge transportation is presented. The model determines optimal shipping routes for roundtrip service...

Current and historic petroleum-related activities in Milford Haven Waterway (MHW; Wales, UK) contribute to hydrocarbon contamination of surficial sediments. Three main hydrocarbon components of sediments were analyzed: (1) aliphatic hydrocarbons of predominantly biogenic origin, representing about 5-15% of total hydrocarbons (THC); (2) polycyclic aromatic hydrocarbons (PAHs) from recent petroge...

We examine spatial competition along a waterway when shippers are distributed over space. Competition is between barge and rail companies and among barge companies. Equilibrium prices are derived for two variations: oligopolistic rivalry between barge and rail operators, and oligopolistic rivalry among barge operators with terminals located at different points on the waterway. In the first vari...
