Testing PrecipGen Across Four Sites

Posted by  Jason Lillywhite

This blog post presents the results of testing PrecipGen across four diverse locations to evaluate its performance:

• Australia Plains, AU
• Grand Junction Walker Field, CO, USA
• Dublin, EI
• Orlando, FL, USA

The findings demonstrate that PrecipGen successfully represents both short- and long-term daily precipitation totals at individual locations, validating its ability to replicate observed climatic behavior across varied environments.

Estimating Exchange Fluxes Between Surface Water and Groundwater Using Stable Isotope and Radon Models

Posted by  Jason Lillywhite

I'm excited to share a recent paper by Lloyd Townley and Jeffrey Turner, which showcases the use of GoldSim software in modeling surface and groundwater interactions. The research introduces the Lake Water Balance Calculator (LWBC), a tool developed using GoldSim, to estimate groundwater-surface water flow rates. This tool leverages transient balance solutions for radon, coupled with volumetric flow equations, and presents results from multiple case studies.

PrecipGen: Long-Term Precipitation Forecasting

Posted by Jason Lillywhite

A GoldSim model that simulates long-term daily precipitation (PrecipGen) has been added to the GoldSim Model Library. We applied the model to locations in Logan, Utah and Dublin Ireland to help evaluate the effectiveness of this model's ability to forecast daily precipitation rates and capture long term droughts. This application is useful for GoldSim modelers looking to incorporate randomly generated rainfall forecasts in their water balance models. The model shows promise in simulating precipitation for a site that is influenced by multi-year wet and dry cycles. Informal testing has been showing signs of robustness and some refinements to the testing are currently underway.

Simulating Daily Precipitation Using a Time Series Element

Posted by Jason Lillywhite

In GoldSim, the Time Series element serves as an effective tool to represent precipitation data. Given the versatility of this element in portraying such data, I felt compelled to share some best practices and tips for those keen on utilizing this kind of data. 

In this article, I will illustrate how to view and interact with measured daily precipitation using a Time Series element. Additionally, I will delve into some data definition properties and demonstrate the use of a Time History Result element to visualize historical trends and compute period statistics. 

This blog post aims to provide insights into modeling with time series data more efficiently, regardless of whether you are a GoldSim novice or an experienced user.

2024 GoldSim User Conference

Posted by Jason Lillywhite

We are excited to announce the return of the GoldSim User Conference, which will be held from September 9th to 11th, 2024 in the beautiful city of Seattle. September is one of the best months to visit, with an average temperature of 71F (22C). 

GoldSim user conferences provide great learning and networking opportunities for both expert and novice users. The conference will be held at the beautiful Seattle Marriott Waterfront and the adjacent Bell Harbor International Conference Center, both with stunning views of the downtown Seattle waterfront. In addition to oral presentations, poster sessions, panel discussions, and training sessions, registration also includes several fun networking events (a dinner cruise on Elliot Bay and a Seattle Mariners game in luxury suites). We look forward to seeing you in Seattle! Register now!
