Duct-ventilated embankment
Introduction The construction of roadway and railway embankments in cold regions can influence the overall thermal response of underlying permafrost. This change in the thermal

Swept Tunnel & Imported Ground Surface
Introduction This is the final example demonstrating the basics of setting up three-dimensional geometries in BUILD3D. In this example, we will import a STEP file

3D Rapid drawdown
Introduction This example replicates the “Rapid drawdown” examples illustrated in SEEP/W and SIGMA/W. The purpose of this example is to demonstrate the steps required to

Thermosyphons in End View
Introduction Thermosyphons are used to harness cold weather to maintain frozen conditions in the soil. A thermosyphon essentially comprises two parts: an evaporator installed below

Source and Exit Boundary Conditions
Introduction There are three basic boundary conditions for contaminant transport: 1) specified concentration (Dirichlet); 2) specified dispersive flux (Neumann); and, 3) specified dispersive and advective

Verification – Heated Closed System
Introduction The objective of this example is to verify the simulated change in pressure of a constant volume of dry air subject to an increase

Land-climate interaction hydraulic
modeling of a soil cover system located
in northern Canada
Introduction Multilayer cover systems are often placed over mine wastes to support the growth of native plant species. The cover system must be designed to

Transport and Consumption of Oxygen in Cover Material
Introduction Acidic leachate is produced when oxidation of sulphide occurs in an unsaturated system through which water transport is occurring. Soil cover systems with capillary
