Exercise - Unconfined Seepage Problems, Part 2

In this exercise, we will solve two additional unconfined seepage problems using XSLOPE. The first problem corresponds to a simple earth dam with a low-permeability core and the second problem corresponds to a dam with a core, filter, and drain. For both cases, we will first prepare the problem inputs in an XSLOPE Excel input file starting with the standard template:

input_template.xlsx

After preparing each input file, launch the following Google Colab notebook to upload the Excel input file and perform the seepage analysis:

Problem 1 - Johnson Reservoir

The Johnson Reservoir problem corresponds to the following cross section:

We will first prepare the problem inputs in an XSLOPE Excel input file. Use the Excel file to specify the material properties, define the geometry using a profile line, and assign boundary conditions.

After preparing the input file, launch the Google Colab notebook to upload the Excel input file and perform the seepage analysis

Problem 2 - Earth Dam with Core, Filter, and Drain

The Earth Dam with Core, Filter, and Drain problem corresponds to the following cross section:

In this case, we will go through the process of deriving the geometry (point coordinates) of the cross section from the image. Enter the resulting profile lines, material properties, etc. in the XSLOPE Excel input file. After preparing the input file, launch the Google Colab notebook to upload the Excel input file and perform the seepage analysis.
