Summary
A novel River Environmental Decision Support System (REDSS) was developed for Shanghai's Suzhou Creek Rehabilitation Project. This flexible system integrates GIS, data marts, and models for effective water environmental management.
Area of Science:
- Environmental Science
- Water Resource Management
- Geographic Information Systems (GIS)
Background:
- The Suzhou Creek Rehabilitation Project (SCRP) in Shanghai is a large-scale initiative addressing water-related environmental issues.
- Effective planning and decision-making are crucial for the success of complex environmental rehabilitation projects.
Purpose of the Study:
- To detail the development and application of a River Environmental Decision Support System (REDSS) for the SCRP.
- To illustrate the flexibility and general applicability of the REDSS framework for water environmental management.
Main Methods:
- Development of a GIS-based analysis using Component technology.
- Implementation of a multi-dimensional "data mart" for integrated and dynamic data querying.
- Integration of hydrodynamic and water quality models for simulating complex tidal river networks and water quality assessment using an Identification Index Method.
Main Results:
- Seamless integration of GIS and non-GIS components within the REDSS.
- Simultaneous querying of diverse data sources for comprehensive analysis.
- Ability to simulate and assess various engineering and management scenarios to support informed decision-making.
Conclusions:
- The developed REDSS provides a flexible and user-friendly framework for scientific planning and decision-making in water environmental rehabilitation.
- The system's general characteristics allow for its application in diverse geographic regions beyond Suzhou Creek.

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...
01:19Quality 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...
01:27Design Example: Design of an Irrigation Channel
Trapezoidal channels are widely used in irrigation systems due to their cost-effectiveness and efficiency in conveying water. Trapezoidal channels feature a flat bottom and sloping sides, making them stable and easier to construct compared to other shapes. The bottom width and side slope ratio are determined based on the required flow capacity and site conditions. The side slope is kept gentle for unlined channels to prevent soil erosion.Hydraulic parameters in channel design include the flow...
01:30Biological Treatment of Effluent and Waste Water
Biological wastewater treatment relies on the metabolic activity of microorganisms to remove pollutants from sewage. In modern treatment systems, this process is organized into sequential stages that progressively reduce solid material, dissolved organic matter, and microbial contamination. Each stage plays a distinct role in improving water quality and preparing the effluent for safe discharge or reuse.Primary and Secondary TreatmentPrimary treatment is a physical process that removes large...
01:21Design Example: Creating a Hydraulic Model of a Dam Spillway
Scaled hydraulic models of dam spillways provide a practical way to replicate and study the intricate flow dynamics of these structures. Often built to a 1:15 ratio, these models allow for observing critical water behavior, such as velocity distribution, flow patterns, and energy dissipation.
01:24Weir
A weir is a hydraulic structure designed to partially obstruct an open channel, enabling precise control and measurement of water flow. By forcing water to flow over or through it, a weir allows for accurate determination of discharge rates, making it an essential tool in water resource management. These structures are extensively used in regulating river flows, irrigation systems, and flood control channels.Types of Weirs and Their FeaturesWeirs are categorized primarily into sharp-crested and...
