Design Example: Analyzing Capacity Contours for Flood Risk Assessment01:17

Design Example: Analyzing Capacity Contours for Flood Risk Assessment

342
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...

Framing Effects

8.0K
Information is everywhere and its presentation—such as how and when items are presented—can impact our perceptions and decisions surrounding the info. This broad concept umbrellas framing effects—influences that occur due to the way information is framed in its appearance, whether it’s purely the order or the specific wording of a message. Let’s take a look at numerous ways in which two versions of something can objectively say the same thing, yet we respond in...

Fundamental Attribution Error

14.0K
According to some social psychologists, people tend to overemphasize internal factors as explanations—or attributions—for the behavior of other people. They tend to assume that the behavior of another person is a trait of that person, and to underestimate the power of the situation on the behavior of others. They tend to fail to recognize when the behavior of another is due to situational variables, and thus to the person’s state. This erroneous assumption is...

The Influence of Cognition on Affect01:29

The Influence of Cognition on Affect

260
Cognition plays a pivotal role in shaping emotional experiences, as demonstrated by Schachter and Singer’s two-factor theory of emotion. According to this model, emotion arises from a combination of physiological arousal and cognitive interpretation. The body’s physiological response to stimuli is ambiguous and only gains emotional significance through cognitive labeling. For instance, an increased heart rate and adrenaline surge while standing near an attractive person may be...

Factors Affecting Perception01:25

Factors Affecting Perception

2.9K
Perception is influenced by perceptual set, context, motivation, and emotion. Perceptual set, or perceptual expectancy, refers to the tendency to perceive things in a particular way, influenced by previous experiences and expectations. This phenomenon affects the interpretation of stimuli, creating a set of mental tendencies and assumptions that impact sensory perceptions of sound, taste, touch, and sight.
An illustrative example of a perceptual set is the scenario where an airline pilot told...

Summary

Coastal residents’ support for flood adaptation policies is influenced by their perception of flood risks. Understanding these perceptions is crucial for effective coastal flood risk management and policy-making.

Area of Science:

  • Environmental Science
  • Social Science
  • Risk Analysis

Background:

  • Coastal flooding causes significant economic damage, exacerbated by development and climate change.
  • Understanding public support for adaptation policies is vital for policymakers.
  • Coastal residents' views on flood adaptation are critical for effective risk management.

Purpose of the Study:

  • Investigate coastal residents' support for relocation incentives and educational programs.
  • Analyze the relationship between flood risk, risk perception, and policy support.
  • Examine the influence of socio-demographic factors on adaptation policy support.

Main Methods:

  • Utilized original survey data from US Gulf Coast counties.
  • Merged survey data with contextual flood risk data.
  • Employed statistical analysis controlling for socio-demographic variables.

Main Results:

  • Socio-demographic factors (age, gender, race, partisanship) significantly impact policy support.
  • Contextual flood risks influence individual risk perceptions.
  • Risk perception mediates the effect of contextual risk on support for flood management policies.

Conclusions:

  • Public support for flood adaptation policies is mediated by risk perception.
  • Effective flood risk communication requires informing the public about current and future risks.
  • Enhanced risk communication tools and information on mitigation options are needed.
