Modeling Integrated Water Resources Management (IWRM) with GoldSim

Creating an Integrated Water Resources Management (IWRM) model is useful for making informed decisions. In this post, I'll explore how to use GoldSim and a combination of pre-built model examples from the GoldSim model library to build an IWRM model that can be used for forecasting and long-term planning.

The model you see here is an example of IWRM because it combines several components: hydrology, a system network, operating rules, water rights law, and water demand forecasting. Let's take a look at how I've modeled each of these.

Note: As you read through this post, you'll see references to many example models in our library and links to our Help Documentation. These resources are designed to help you build and customize your own model.

An Investigation into Long-Term Precipitation Patterns in the Pacific Northwest

When modeling long-term precipitation, a question is how to account for climate change. A common approach is to analyze historical data for trends, but what happens when a simple analysis of precipitation totals doesn't show a clear signal? This post documents an investigation into a more nuanced approach for a stochastic precipitation model.
