Summary
This study developed a groundwater contamination prevention mapping system using analytic hierarchy process and GIS. The resulting maps accurately guide practical prevention and supervision measures for groundwater resources.
Area of Science:
- Environmental geology
- Hydrogeology
- Geographic Information Systems (GIS)
Context:
- Groundwater contamination poses a significant threat to water resources, necessitating effective prevention strategies.
- Geological surveys and assessments require robust mapping tools for planning and implementation.
- Existing methods may not fully integrate natural, socio-economic, and policy factors.
Purpose:
- To construct a comprehensive groundwater contamination prevention mapping system.
- To couple groundwater risk assessment, value, and wellhead protection area zoning.
- To provide a basis for informed groundwater contamination prevention planning.
Summary:
- A novel groundwater contamination prevention mapping system was developed by integrating natural, socio-economic, and policy perspectives.
- Analytic hierarchy process and GIS were employed for data processing, risk assessment, and visualization.
- The system successfully generated a groundwater prevention map for Beijing Plain, reflecting actual conditions and priorities.
Impact:
- The developed mapping system provides a practical tool for guiding groundwater contamination prevention and supervision.

01:17Design Example: Analyzing Capacity Contours for Flood Risk Assessment
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...
01:29Topographic Surveying and Contours
Topographic surveying is critical for documenting the Earth's surface, focusing on capturing elevations, slopes, and natural and man-made features. It is essential in construction planning, water resource management, and land-use analysis. The primary outcome of such surveys is a topographic map, which uses contour lines to visually represent the shape and slope of the terrain, providing valuable insights into the landscape's characteristics.Contour lines are fundamental to understanding the...
01:21Manipulation and Analysis
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...
01:29Applications of GIS: Disaster Management and Emergency Response
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...
01:25Selected Data About Geographic Locations
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...
01:29Plotting of Topographic Maps
Topographic maps represent the Earth's surface features using contour lines, which connect points of equal elevation to create a two-dimensional representation of three-dimensional terrain. Creating a topographic map requires a systematic approach.Begin by plotting a scaled grid and marking intersections corresponding to the survey's elevation data points. Assign elevation values at these intersections to build the base map. Next, determine contour levels using a consistent contour interval,...
