AIS (Automatic Identification System) data provides valuable input parameters in ship traffic simulation models for risk analysis and the prevention of shipping accidents. This paper reports on the detailed analysis of AIS data for modeling purposes. This analysis is focused on restricted waterways to support inland waterway simulations, comparing the differences between a narrow waterway in th...

The US Coast Guard (USCG) is charged with maintaining an acceptable level of safety in US ports and waterways. Allocating resources to solve safety problems is difficult because multiple attributes of a port or waterway affect its safety and determine whether a particular safety measure will improve it. We based the ports and waterways safety assessment (PAWSA) model on multiattribute decision ...

Because of climate change, the erection dams through transboundary rivers, and shortage water resources, countries worldwide are facing several challenges. Unconventional resources such as recycling wastewater urgently needed to overcome demand–supply gap. The bioreactor is considered an effective means removing contaminants enhancing self-purification on open waterways. This study numerically ...
