Simulating Controlled and Uncontrolled Reservoir Discharges

Posted by Jason Lillywhite

When simulating ponds and reservoirs in GoldSim, one of the most common types of systems we see are the combination of controlled and uncontrolled discharges. Examples of uncontrolled discharges include evaporation losses and flood flows over a spillway. Examples of controlled discharges include water that is pumped out or flows through an opening in the outlet works. Controlled outflows deliver water to service necessary uses downstream such as irrigation or industrial water demands.

In this blog post, I will walk through the process of setting up this type of model in GoldSim. Hopefully this will provide a good resource for those of you working on conceptual water balance models for your projects.

Run-of-the-River Hydroelectric Power Generation

A new model was added to our library that simulates run-of-the-river hydroelectric power generation. This model simulates a dam that is operated at a constant water level with insignificant amount of storage compared to the daily flow through. It is based on work by one of our expert modelers for a project on the Aksu River, located in northeastern Turkey. Below is a picture showing the dam that this model was originally created for.
