Summary
Sponge city construction offers a sustainable urban water management solution. This study developed assessment indicators and found differences in how officials and the public perceive water management priorities and satisfaction.
Area of Science:
- Environmental Science
- Urban Planning
- Water Resource Management
Background:
- Cities worldwide face increasing water-related challenges, including extreme weather events and chronic stresses like water scarcity.
- Developing urban models where water and environment coexist is crucial for sustainable city development.
- Sponge city construction is proposed as a viable strategy to address these urban water issues.
Purpose of the Study:
- To construct a comprehensive sponge city assessment indicator system.
- To compare the perceptions of government officials and the public regarding sponge city construction.
- To identify discrepancies in evaluating water management importance and satisfaction.
Main Methods:
- Developed a sponge city assessment indicator based on pre-assessment dimensions.
- The indicator encompasses three systems: water ecosystem, socioeconomic, and institutional/mechanism.
- Employed fuzzy multiple criteria decision-making, evaluating degrees of importance and satisfaction to compare official and public viewpoints.
Main Results:
- A significant difference (0.8-1) was observed in the evaluation dimensions between officials and the public.
- Discrepancies were noted in the perceived importance of water management and water use.
- Differences in satisfaction levels were found concerning water development, water efficiency, and institutional mechanisms.
Conclusions:
- The developed indicators provide a framework for evaluating sponge city construction and stormwater management.
- The fuzzy multiple criteria approach effectively highlights differing perspectives between officials and the public.
- Findings offer valuable insights for refining water management strategies and decision-making processes.

01:09Decision Making: P-value Method
6.7K
The process of hypothesis testing based on the P-value method includes calculating the P- value using the sample data and interpreting it.
First, a specific claim about the population parameter is proposed. The claim is based on the research question and is stated in a simple form. Further, an opposing statement to the claim is also stated. These statements can act as null and alternative hypotheses: a null hypothesis would be a neutral statement while the alternative hypothesis can...

Decision-making is a fundamental cognitive process that involves evaluating alternatives and selecting among them. This process can range from simple choices, such as deciding what to wear, to complex decisions, like choosing a major in college or a career path. The complexity of the decision often dictates the approach we use, which can be broadly categorized into two types: automatic and controlled decision-making.

Response Surface Methodology (RSM) is a collection of statistical and mathematical techniques used to develop, improve, and optimize processes. It is particularly valuable when many input variables or factors potentially influence a response variable.

01:22Design Consideration
475
Designing a structure involves a series of considerations, primarily the material's ultimate strength, calculated through tests that measure changes under increased force until the material reaches its breaking point or limit. The ultimate load, where the material breaks, is divided by its original cross-sectional area, resulting in the ultimate normal stress or strength. The ultimate shearing stress is another significant factor taken into account.

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.
