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

Design Example: Analyzing Capacity Contours for Flood Risk Assessment

86
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...

Precipitation Gravimetry01:03

Precipitation Gravimetry

6.8K
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...

Influence of Earth's Curvature and Atmospheric Refraction on Leveling01:26

Influence of Earth's Curvature and Atmospheric Refraction on Leveling

187
During leveling, the Earth's curvature and atmospheric refraction introduce deviations in the line of sight from a true horizontal reference. When the line of sight is leveled, it remains perpendicular to the plumb line only at a single point. Beyond this, it deviates due to the Earth’s curvature, represented by the correction C. For a sight distance D, the deviation can be derived using the relationship:This relationship shows that the deviation increases quadratically with distance.

Typical Model Studies

411
Fluid mechanics model studies often utilize scaled-down systems to predict fluid behavior in full-scale environments, such as river flows, dam spillways, and structures interacting with open surfaces. Maintaining Froude number similarity in river models is crucial, as it replicates surface flow features like wave patterns and velocities.

Geoid and Ellipsoid01:28

Geoid and Ellipsoid

86
The Earth's shape is best described as an ellipsoid, a slightly flattened sphere created by rotating an ellipse around its minor axis. This flattening results in the polar axis being about 21 kilometers shorter than the equatorial axis. In contrast, the geoid represents the Earth's gravitational shape and aligns with the mean sea level (MSL). The geoid is an irregular equipotential surface where gravity is perpendicular at every point. Variations in Earth's mass distribution cause geoid...

Uniform Depth Channel Flow: Problem Solving01:18

Uniform Depth Channel Flow: Problem Solving

107
To calculate the flow rate for a trapezoidal channel, first, identify the bottom width, side slope, and flow depth of the channel. The cross-sectional area (A) corresponding to the depth of flow (y), channel bottom width (B), and side slope (θ) is determined by:Next, calculate the wetted perimeter, which includes the bottom width and the sloped side lengths in contact with the water. Using the values of the cross-sectional area and the wetted perimeter, determine the hydraulic radius by...

Area of Science:

  • Oceanography
  • Coastal Geomorphology
  • Climate Change Science

Background:

  • Sea level rise (SLR) projections are crucial for coastal management.
  • Ocean surface variability introduces significant uncertainty in flood impact assessments.
  • Existing methods like VDatum have limited geographic applicability.

Purpose of the Study:

  • To develop a novel method for incorporating ocean surface variability into SLR flood projections.
  • To create an Ocean Reference Surface (ORS) as a proxy for local mean higher high water.
  • To generate probability-based SLR flood projections for areas lacking VDatum coverage.

Main Methods:

  • Analysis of Regional Ocean Modeling System reanalysis data to create an Ocean Reference Surface (ORS).
  • Incorporation of ORS into bathtub flooding models to account for ocean surface level uncertainty.
  • Comparison of ORS-based flood projections with the Tidal Constituents and Residual Interpolation (TCARI) method.
  • Validation of ORS using tide gauge observations at the Honolulu tide gauge.

Main Results:

  • The ORS method successfully incorporates ocean surface uncertainty into SLR flood modeling.
  • Probability-based flood projections were generated for O'ahu, Hawai'i, using NOAA SLR scenarios.
  • ORS-derived projections showed improvements compared to TCARI, particularly for areas without VDatum.
  • ORS pixel values correlated well with observed tide gauge data, validating the approach.

Conclusions:

  • The ORS method provides a more realistic assessment of daily higher high water, improving SLR flood projections.
  • This approach is valuable for coastal areas where VDatum is not available, enhancing climate adaptation planning.
  • Acknowledging uncertainty and user-defined probability is essential for accurate flood risk identification and management.
