Soil Mechanics – Seepage through Soil at an Angle α to the Horizontal | Darcy’s Law | Geotechnical Excel Spreadsheets

[GEO-2025-0135] – By Dr. Ahmad Fahmi

We are excited to introduce the Seepage through Soil at an Angle α to the Horizontal spreadsheet pack, part of the Geotechnical Excel Spreadsheets (2025-1) collection. This set includes 9 essential spreadsheets designed for soil mechanics professionals and students to analyze seepage through soil using Darcy’s Law. The pack focuses on seepage analysis in soils when the flow occurs at an angle to the horizontal, a crucial consideration in geotechnical engineering projects like drainage systems, earth dam design, and foundation investigations.

What’s Included in the 9 Spreadsheets?

  1. Start: Darcy’s Law Start Sheet – Introduction to seepage through soil at an angle α to the horizontal.
  2. Darcy’s law alpha-01: Hydraulic Gradient Concept – Part 1 – Introduction to hydraulic gradient and its application in seepage analysis.
  3. Darcy’s law alpha-02: Hydraulic Gradient Concept – Part 2 – Further exploration of the hydraulic gradient concept and its impact on flow behavior.
  4. Darcy’s law alpha-03: Darcy’s Law Concept – Part 1 – Basics of Darcy’s Law applied to soil seepage at an angle.
  5. Darcy’s law alpha-04: Darcy’s Law Concept – Part 2 – Advanced calculations using Darcy’s Law in seepage scenarios with a focus on angles.
  6. Darcy’s law alpha-05: Flow Rate Calculation – Part 1 – Calculating flow rate through soil using Darcy’s Law for angled flow.
  7. Darcy’s law alpha-06: Flow Rate Calculation – Part 2 – Continuing flow rate analysis with Darcy’s Law for angled soil conditions.
  8. Darcy’s law alpha-07: Flow Rate Calculation – Part 3 – Final calculations and visualizing flow rate for seepage through soils at an angle.
  9. Darcy’s law alpha-08: Flow Rate Calculation – Part 4 – Additional advanced calculations for seepage flow rate in soils subjected to angled conditions.
