River water quality in the Humber catchment: an introduction using GIS-based mapping and analysis
The Science of the Total Environment
|June 10, 2000
Summary
Regional water quality in the Humber catchment was mapped, revealing pollution sources like sewage, mining, and agriculture. GIS analysis identified key factors influencing water chemistry across different zones.
Area of Science:
- Environmental Science
- Water Quality Management
- Geographic Information Systems (GIS)
Background:
- The Humber catchment's water quality is influenced by diverse anthropogenic and natural factors.
- Understanding these influences is crucial for effective environmental management and protection.
Purpose of the Study:
- To map the regional water quality of the Humber catchment for key inorganic chemical determinands.
- To identify the major factors affecting water quality characteristics using a GIS system.
Main Methods:
- Utilized a Geographic Information System (GIS) for spatial analysis.
- Employed an extensive monitoring database from the Environment Agency and LOIS.
Main Results:
- Sewage inputs significantly elevate determinand concentrations in urban areas.
- Particulate component concentrations increase in tidal zones due to sediment dynamics.
- Localized high concentrations are linked to coal mine drainage, historical ore mining, geology, agriculture, and seawater intrusion.
Conclusions:
- Water quality is a complex interplay of urban, industrial, agricultural, and geological factors.
- GIS mapping effectively visualizes and identifies pollution hotspots and their sources.
- Management strategies must address diverse inputs to improve Humber catchment water quality.

01:19Quality of Water
In concrete preparation, the quality of water is paramount as it affects the strength and durability of the concrete. Potable water is usually preferred; however, it must not have excessive sodium or potassium to prevent compromising the concrete's integrity. Water quality is typically evaluated based on impurities such as dissolved solids, chlorides, and sulfates, and its pH value is ideally between 6 and 8. Even slightly acidic natural water may be acceptable unless it contains harmful...
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...
01:25Selected 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...
01:21Manipulation 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...
01:17Design Example: Alignment of a Road Line Using GIS
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...
