    A prototype network geographic information system (GIS) was developed to: (i) improve the effectiveness of a complex municipal solid waste landfill siting procedure; (ii) make siting-related information available to the general public; (iii) assist local environmental protection agencies in maintaining a GIS; and (iv) facilitate the central environmental protection agency in managing, instructing and evaluating the progress of a local siting. Siting analysis is performed with computerized mapping analysis to save time and effort of data processing. A multimedia network interface is provided for 24-hour local or remote access to the system from anywhere on the Internet. This networking capability allows a user without tools to utilize the system and to avoid the cost of system installation and training appropriate personnel to manage the system. Moreover, a case study for Miaoli is described. Environmental, social, economic and engineering feasibility issues are evaluated for the suitability of a candidate landfill site. (C) 1997 ISWA.

    The effect of a gravel subgrade on the hydraulic performance of GCLs is investigated. Laboratory test results show that the GCL specimens exhibit significant variation in thickness when compressed against gravel. The maximum and minimum thicknesses of the specimen were about 20 and 3 mm, respectively, after consolidation by an effective stress up to 138 kPa. However, the permittivity of GCLs remained very low. The permittivity of both needle-punched and adhesive-bonded geotextile-supported GCLs decreased with increasing confining stress, regardless of the type of subgrade materials. In general, larger particles led to more significant migration of bentonite. Nevertheless, there was no significant difference in the degree of bentonite migration between the two GCLs investigated.

    Parallelised branch-and-bound algorithm for raster-based landfill siting

    Landfill siting analysis is complex when compactness and other factors are simultaneously evaluated. In our previous work, a raster-based mixed-integer model was proposed to overcome this difficulty, and a C program was further developed to improve the computational time for solving the raster-based model. In this study, an enhanced parallelised branch-and-bound algorithm was proposed to shorten the solving time further. A parallelised computing environment with five computers was established for implementing the proposed algorithm. For comparison purpose, the un-parallelised algorithm was also tested on a single computer. The results show that the parallelised algorithm and computing environment can increase the speed by about three to seven times, while compared to the original algorithm implemented on a single computer.
