概括
本研究使用基于GIS的框架确定了卡弗尔·埃尔谢赫市最佳的建筑和拆除废物 (CDW) 处置地点. 研究通过实地调查和专家的意见来完善标准,提供一个更好的废物管理的适用性地图.
科学领域:
- 环境工程与环境管理
- 城市规划和废物管理
- 地理信息系统 (GIS) 和空间分析
背景情况:
- 越来越多的建筑和拆除项目产生大量的建筑和拆除废物 (CDW),通常是非法倾倒的,造成环境和健康风险.
- 现有的文献缺乏关于在埃及城市中选择最佳的CDW处置或回收地点的研究,没有实地调查来验证区域标准或评估当前的垃圾填埋场.
- 这一差距凸显了在该地区对CDW管理采取本地化,数据驱动的方法的需要.
研究的目的:
- 开发和应用基于多个标准的GIS框架,以确定埃及卡弗尔·埃尔谢赫市的最佳建筑和拆除废物 (CDW) 处置地点.
- 通过文献审查,现场调查和专家重点小组,完善选址标准,确保区域适用性.
- 在开发的框架内评估现有CDW垃圾场的适用性.
主要方法:
- 采用了集成地理信息系统 (GIS) 的多标准决策分析 (MCDA) 框架.
- 从文献中确定了标准,并通过实地调查和与当地专家合作的焦点小组来改进.
- 梯形间隔II型模糊分析层次过程 (AHP) 和基于的聚合被用来计算和结合专家加权的地点适宜性分析标准.
主要成果:
- 创建了一个CDW处置场所的适用性地图,将地区分为优秀,非常好,好,平均,差,非常差.
- 权重标准模型显示"优秀"适合性区域 (6.48%) 与同等权重模型 (5.96%) 相比增加,主要是在东北部.
- 最适合的地区位于城市郊区,适合性向中央商务区下降. 根据加权模型,现有的倾倒场大多属于"差"到"平均"类别.
结论:
- 拟议的基于GIS的MCDA框架有效地识别了最佳的CDW处置地点,并在埃及城市环境中评估现有的处置地点.
- 该方法为废物管理规划和决策提供了宝贵的见解,可适应不同的权重场景.
- 该研究强调了局部化标准和专家投入对于有效的建筑和拆除废物管理策略的重要性.

Design Example: Alignment of a Road Line Using GIS
49
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...

Applications of GIS: Disaster Management and Emergency Response
87
Geographic Information System (GIS) technology is essential for risk identification, action prioritization, and resource optimization in critical situations like flooding and earthquakes. By integrating spatial and demographic data, GIS provides a comprehensive framework for emergency response.GIS integrates data layers, like rainfall intensity, topography, elevation profiles, and river levels, to model high-risk flood zones. These layers assess areas susceptible to flooding based on their...

Design Example: Analyzing Capacity Contours for Flood Risk Assessment
48
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...

Manipulation and Analysis
26
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...

Selected Data About Geographic Locations
27
Geographic Information Systems (GIS) rely on two core types of data: spatial data and attribute data.Spatial DataSpatial data defines the physical location of features within a coordinate system, typically expressed in terms of latitude and longitude. It provides precise positioning for elements like roads, rivers, or buildings.Attribute DataAttribute data complements spatial data by adding descriptive information about these features. For example, a road's spatial data includes its start and...

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...
