Design Example: Analyzing Capacity Contours for Flood Risk Assessment

358
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...

Methods of Obtaining Topography

443
Topography involves measuring and mapping land elevations, natural features, and artificial structures to create accurate representations of the terrain. Topographic surveying relies on traditional and modern methods, each with distinct advantages and limitations.Traditional Surveying Methods:Transit stadia surveys and plane table surveys were widely used traditional surveying methods. These techniques relied on instruments like theodolites and stadia rods for measuring distances and angles,...

Precipitation Gravimetry01:03

Precipitation Gravimetry

16.0K
Precipitation gravimetry is based on converting an analyte into a sparingly soluble precipitate, which is separated by filtration and weighed. An ideal precipitate should be pure, insoluble, of known composition, and easily filtered from the reaction mixture.
In determining nickel by gravimetric analysis, a precipitant of ethanolic dimethylglyoxime is added to a hot nickel salt solution. This is quickly followed by the dropwise addition of dilute ammonia solution until precipitation occurs. A...

Area of Science:

  • Geosciences
  • Environmental Science
  • Chemical Engineering

Background:

  • Predicting gas migration in water-saturated porous media is crucial for carbon sequestration, hydrogen storage, and groundwater remediation.
  • Gas migration exhibits complex behaviors (continuous vs. discontinuous flow) influenced by flow rates and porous medium properties.
  • Invasion-Percolation (IP) models are established for discontinuous flow, but their efficacy in transitional and continuous regimes remains underexplored.

Purpose of the Study:

  • To develop and present a quantitative framework for comparing and ranking macroscopic Invasion-Percolation models.
  • To evaluate IP model performance against experimental data in transitional and continuous gas flow regimes.
  • To assess the impact of pore-scale heterogeneity on IP model predictions.

Main Methods:

  • Utilized a diffused Jaccard coefficient to quantify similarity between IP model outputs and high-resolution experimental images.
  • Employed multiple random realizations of the initial invasion threshold field to simulate pore-scale heterogeneity.
  • Averaged Jaccard coefficients across realizations to evaluate model performance and calibrate parameters.

Main Results:

  • Identified specific macroscopic IP model versions suitable for transitional and continuous gas flow regimes.
  • Demonstrated that heterogeneity in the initial invasion threshold field significantly impacts model performance.
  • Confirmed the applicability of IP models in previously unevaluated flow regimes.

Conclusions:

  • Macroscopic IP models can effectively predict gas migration in transitional and continuous flow regimes, offering computational cost savings over continuum models.
  • The developed framework provides a robust method for model comparison and calibration using experimental data.
  • The framework's generalizability extends beyond gas-water systems to diverse modeling scenarios with resolved data.
