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

Design Example: Analyzing Capacity Contours for Flood Risk Assessment

126
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

511
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

147
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...

Testing Water Quality01:14

Testing Water Quality

198
When the quality of water for concrete preparation is uncertain, its impact on the setting time of cement and compressive strength of mortar is assessed by comparison with de-ionized or distilled water benchmarks. American Society for Testing and Materials (ASTM) C1602 requires the setting times to be within 90 minutes of the control, British Standard (BS) 3146:1980 allows a 30-minute variance in the initial setting, while British Standards European Norm (BS EN) 1008 specifies initial setting...

Area of Science:

  • Coastal hydrogeology
  • Aquifer hydraulics
  • Geotechnical engineering

Background:

  • Tidal response methods are crucial for estimating hydraulic parameters in coastal aquifers.
  • Subsurface barrier walls are employed to mitigate saltwater intrusion in coastal environments.
  • Evaluating the effectiveness of these barrier walls is essential for water resource management.

Purpose of the Study:

  • To extend an analytical solution for groundwater tidal response.
  • To evaluate the hydraulic performance of a subsurface barrier wall.
  • To assess the feasibility of using tidal response for barrier function evaluation.

Main Methods:

  • Utilized an existing analytical solution for tidal response of groundwater levels.
  • Extended the analytical model to incorporate a subsurface barrier wall.
  • Conducted a field study at Komesu Dam, Japan, with paired observation sites.
  • Analyzed groundwater-level time series data to derive hydraulic parameters.

Main Results:

  • Groundwater-level data near a penetrating pipe showed a sinusoidal tidal component, unlike other sites.
  • Derived approximate hydraulic parameters of the barrier wall between paired observation sites.
  • Observed differences in derived parameters indicated the method's sensitivity to wall integrity.

Conclusions:

  • The extended tidal response method shows promise for evaluating subsurface barrier wall function.
  • This approach can help assess the effectiveness of saltwater intrusion prevention measures.
  • Further refinement of the simple formulas may improve parameter accuracy.
