The concept of disaster resilience has received considerable attention in recent years and it is increasingly used as an approach for understanding the dynamics of natural disaster systems. No models are available in literature to measure the performance of natural gas network, therefore, in this paper, a new performance index measuring functionality of gas distribution network have been proposed to evaluate the resilience index of the entire network. It can be used for any type of natural or manmade hazard which might lead to the disruption of the system. The gas distribution network of the municipalities of Introdacqua and Sulmona, two small towns in the center of Italy which were affected by 2009 earthquake have been used as case study. Together the pipeline network covers an area of 136 km2, with 3 M/R stations and 16 regulation groups. The software SynerGEE has been used to simulate different scenario events. The numerical results showed that, during emergency, to ensure an acceptable delivery service, it is crucial to guarantee the functionality of the medium pressure gas distribution network. Instead to improve resilience of the entire network the best retrofit strategy is to include emergency shutoff valves along the pipes.

Permeability Rate

This research has investigated the geotechnical properties of abandoned open pits in Thailand’s eastern province of Chachoengsao that could become targets for illegal industrial waste dumping. Out of a total of 11 districts, this research focuses on two districts, i.e. Plaengyao and Panom Sarakarm, due to the proximity to industrial estates and abundance of open pits. The findings reveal a very low permeability rate of Plaengyao’s surface soil, indicating that no open pits should be used as dumping sites as contaminants are captured by and deposited in the surface soil. Clay liner and surface drainage are needed to be considered for Landfills in Plaengyao district. In contrast, the surface soil of Panom Sarakarm district is of high permeability and thereby renders the utilization of open pits environmentally harmful since the dissolved contaminants can leach through the ground and pollute groundwater.
