A dynamic water balance model for drought management: A case study of the Invitational Drought TournamentDownload
System dynamics modelling provides an effective approach for water management, as shown in this thesis, using Agriculture Canada’s Invitational Drought Tournament (IDT) as a case study. The objectives of the research are to simulate basin-scale management of the fictitious Western Canadian “Oxbow...
This thesis aims to demonstrate the feasibility of using System Dynamics (SD) techniques to develop a transparent, open-source and reproducible model capable of simulating long-term soil water dynamics in a tailings-cap system subject to upward flux from a consolidating tailings substrate. The...
Traditionally, multi-disciplinary modelling exercises involve one discipline mechanistically using the output from a black-box model developed by another discipline. To address this deficiency, the research uses techniques relatively new to the geotechnical community, such as System Dynamics (SD)...
Productivity plays a key role in the successful delivery of construction projects, and it has long been a major research interest within the construction engineering domain. Previous research on the identification of factors influencing productivity often focused on labour intensive activities...
Decision makers require accurate estimates of water demand for the planning and operation of water resource systems. Short-term water demand forecasting can offer immediate information to assist daily or weekly operation while accurate long-term forecasting allows water utilities or governments...
A system dynamics (SD) model was developed in the Tailings Management Simulator (TMSim) to simulate consolidation processes under quiescent conditions. A top-down iterative approach guides the overall philosophy of the modelling process. The GoldSim software was used as the main simulation...
Tailings Management System (TMS) consists of a web of inter-related sub-systems across disciplinary and organizational boundaries. Conventional predictive models simulate physical processes in each discipline with great details. In contrast, simulation based on System Dynamics (SD) focuses on...
Implemented in GoldSim, TMSim_Consol uses an explicit finite difference method to calculate the void ratio at each time step. Through various validation cases, the consolidation sub-model demonstrates its capability in carrying out both deterministic and stochastic simulations of tailings...
Unsaturated Flow Model
The un-saturated flow sub-model is based on a previously developed infiltration-drainage model. This research improves the original model by adding capabilities of handling dynamic boundary conditions and inter-layer overflow mechanisms. Additional validation cases are conducted to build...
