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

Design Example: Analyzing Capacity Contours for Flood Risk Assessment

33
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...

Effect of Sea Water on Concrete01:22

Effect of Sea Water on Concrete

122
Concrete exposed to seawater can undergo degradation like the dissolution of ettringite and gypsum, increasing the material's porosity and decreasing its strength. In contrast, the crystallization of salts within the concrete's pores can cause expansion, particularly above the waterline where evaporation occurs. Nonetheless, this expansion only happens when seawater, enabled by the concrete's permeability, manages to infiltrate the structure.
Concrete in areas between tide marks,...

Design Example: Maintaining Level of an Embankment

44
Constructing a roadway embankment over uneven terrain requires precise leveling to ensure stability and proper drainage. Surveyors use a leveling instrument and staff to calculate ground elevations and determine the required fill material at each point along the embankment alignment.The process begins by positioning a leveling instrument near a benchmark with a known elevation. A backsight reading establishes the instrument height, which serves as a reference for subsequent measurements. A...

Adaptations that Reduce Water Loss01:57

Adaptations that Reduce Water Loss

25.0K
Though evaporation from plant leaves drives transpiration, it also results in loss of water. Because water is critical for photosynthetic reactions and other cellular processes, evolutionary pressures on plants in different environments have driven the acquisition of adaptations that reduce water loss.

Keystone Species01:39

Keystone Species

21.5K
Measures of species biodiversity, such as richness (i.e., the number of species present) and evenness (i.e., their relative abundance), describe an ecological community’s structure. Many factors affect community structure, including abiotic factors (e.g., sunlight and nutrients), disturbances (e.g., fire or flood), species interactions (e.g., predation or competition), and chance events (e.g., foreign species invasion). Certain species—such as keystone species—also play a...

Area of Science:

  • Environmental Science
  • Climate Change Adaptation
  • Coastal Management

Background:

  • Nature-based coastal defense (NBCD) is promoted for climate risk reduction due to perceived effectiveness and cost-efficiency.
  • However, a critical evaluation of NBCD implementation and performance is needed, especially in diverse geographical contexts.

Purpose of the Study:

  • To analyze the performance of 23 nature-based coastal defense projects in French overseas territories.
  • To assess enabling conditions, risk reduction effectiveness, and externalities of these projects.
  • To identify barriers and levers influencing the success of nature-based solutions for coastal defense.

Main Methods:

  • An ex-post expert judgment method was employed to evaluate 23 implemented NBCD projects.
  • Projects were assessed based on context, governance, funding, social acceptability, technical effectiveness, and contribution to adaptation.
  • Data on project characteristics, performance indices, and identified barriers/levers were collected and analyzed.

Main Results:

  • Projects primarily targeted coastal erosion (80%), often involving restoration (87.1%) in natural/rural areas (47.8%).
  • Highest performance scores were for governance and social acceptability; lowest scores were for risk reduction effectiveness.
  • No project included risk reduction evaluation or calibration for future risks; common barriers included lack of political support and long-term funding.

Conclusions:

  • While NBCD projects demonstrate strengths in governance and social aspects, their technical effectiveness in risk reduction requires significant improvement.
  • Addressing barriers such as securing sustained funding, gaining political backing, and adapting to land tenure issues is crucial for enhancing NBCD performance.
  • Future NBCD strategies must incorporate robust monitoring, evaluation, and calibration for future climate risks to ensure long-term success.
