Soil Mechanics – Flow Net & Flow Rate Concept for Dams | Seepage Analysis | Geotechnical Excel Spreadsheets

[GEO-2025-0137] – By Dr. Ahmad Fahmi

We are excited to introduce the Flow Net & Flow Rate Concept spreadsheet pack for dams, part of the Geotechnical Excel Spreadsheets (2025-1) collection. This set includes 8 essential spreadsheets designed for soil mechanics professionals and students to analyze and calculate flow net and flow rate beneath concrete dams, with a focus on seepage analysis through soil at an angle α to the horizontal.

These spreadsheets provide detailed calculations and analysis for flow channels, potential drops, and the flow rate formula beneath a concrete dam, along with Darcy’s Law applications in various soil sections (circle, rectangle, and square).

What’s Included in the 8 Spreadsheets?

  1. Start: GEOtExcel: Flow Net Concept & Calculation – Introduction to the flow net concept and seepage analysis.
  2. Flow Net-Dam-01: Flow Channels and Potential Drops Beneath a Concrete Dam – Layout 1.
  3. Flow Net-Dam-02: Flow Channels and Potential Drops Beneath a Concrete Dam – Layout 2.
  4. Darcy’s law-Circle: Seepage through soil at an angle α to the horizontal – Circular section analysis using Darcy’s Law.
  5. Darcy’s law-Rectangle: Seepage through soil at an angle α to the horizontal – Rectangular section analysis using Darcy’s Law.
  6. Darcy’s law-Square: Seepage through soil at an angle α to the horizontal – Square section analysis using Darcy’s Law.
  7. Formula Concept: Flow Rate Calculation Beneath a Concrete Dam – Formula concept and calculation for seepage through soil.
  8. Concept Conclusion: Flow Rate Calculation Beneath a Concrete Dam – Concept conclusion and summary of results.

Applications in Soil Mechanics and Geotechnical Engineering:

  • Seepage Analysis: Understand seepage through soil beneath concrete dams, considering flow at an angle α to the horizontal.
  • Flow Rate Calculations: Accurately calculate flow rate for soil water movement beneath a dam using Darcy’s Law.
  • Flow Channel Analysis: Calculate flow channels and potential drops in different soil sections (circle, rectangle, square).
  • Dam Design: Essential for dam engineering, hydrological studies, and foundation design.
  • Ideal for Geotechnical Engineers: Useful for site investigations, groundwater flow analysis, and foundation stability.
  • Educational Tool: Perfect for soil mechanics and geotechnical engineering courses focused on seepage and flow behavior.
