Summary
Comparing international landfill siting guidelines reveals significant differences. These variations in regulations impact the identification of suitable sites for municipal solid waste management using geographic information system (GIS) methods.
Area of Science:
- Environmental Science
- Geographic Information Systems (GIS)
- Urban Planning
Background:
- Effective landfill siting is crucial for preventing long-term environmental damage.
- International regulations and guidelines for landfill site selection vary significantly.
- Comparative analysis of these guidelines is needed to understand their impact on decision-making.
Purpose of the Study:
- To conduct a comparative study of municipal solid waste landfill siting criteria from eight global bodies.
- To apply a GIS multi-criteria evaluation model for identifying suitable landfill sites.
- To analyze the influence of differing guideline specifications on spatial results.
Main Methods:
- Comparative policy analysis of landfill siting criteria from Malaysia, Australia, India, U.S.A., Europe, China, the Middle East, and the World Bank.
- Development and application of a GIS multi-criteria evaluation model using constraint mapping and weighted linear combination.
- Utilization of the Analytic Hierarchy Process (AHP) for determining criterion weights based on decision-maker preferences.
Main Results:
- Significant spatial differences in suitable landfill sites were observed due to variations in national and international guidelines.
- The GIS-based multi-criteria evaluation model effectively integrated diverse criteria for site suitability assessment.
- The Analytic Hierarchy Process highlighted the importance of decision-maker preferences in weighting environmental and social factors.
Conclusions:
- Dissimilarities in landfill siting guidelines directly affect the outcome of suitability analyses and decision-making processes.
- A standardized approach to landfill siting criteria could improve consistency and efficiency in waste management planning.
- GIS and AHP offer robust tools for objective and data-driven landfill site selection.

473
The alignment of a road line using Geographic Information Systems (GIS) is a critical process in civil engineering, combining advanced technology with practical decision-making. This methodology begins with the collection of geospatial data, including information on land cover, geomorphology, drainage patterns, slope, and contour details. Such data is typically acquired through satellite imagery and GIS tools, offering a comprehensive understanding of the terrain.Once the data is gathered, it...

GIS manipulation and analysis functions are vital for decision-making and planning. These activities range from data retrieval tasks, such as selecting information based on specific criteria, to advanced analytical techniques that address complex spatial problems.One critical GIS analysis method is overlaying, which combines multiple data layers to examine impacts. For example, overlaying a river-dammed lake boundary with road networks can identify affected infrastructure. Another common...

391
Flood risk assessment involves careful planning and analysis to ensure the safety of communities near water retention structures. Capacity contours are a vital tool in this process, as they illustrate the potential spread of water at specific levels in a given area. In the context of building a bund across a small valley, these contours play a critical role in evaluating the safety of nearby residential areas.In this example, the bund is intended to store stormwater in the valley. The engineers...

The right type and quality of aggregates are crucial for concrete as they significantly influence its properties, mix proportions, and cost-effectiveness. If different sources are available for sand, the commonly used fine aggregate in concrete, the selection of sand is primarily based on its gradation.
The grading, or particle-size distribution, of sand is determined using sieve analysis, with standard sizes ranging from 150 μm to 10 mm (ASTM No. 100 sieve to 3⁄8 in. sieve). Sand is...

In the past, planning projects such as schools or public facilities required extensive manual effort to gather and compile data. Information such as property boundaries, soil characteristics, road networks, zoning regulations, and flood zones had to be sourced individually from courthouses, utility providers, and registry offices. Assembling these datasets into a coherent format often took several months, delaying project timelines.The introduction of Geographic Information Systems (GIS)...

Surveyors use Global Positioning System (GPS) technology to measure the precise location and elevation of points on Earth. In a recent survey, GPS receivers were used to determine the coordinates and elevations of two park monuments. The process involved careful mission planning, data collection, and correction to ensure accuracy. The survey began with mission planning to identify optimal satellite visibility and minimize Position Dilution of Precision (PDOP). A geodetic control point...
