Welcome to the Model Library

Welcome to my interactive model library. I created this space to share some examples of my core products and to show how we can build web-enabled interactive tools. One example is the Real-Time Hydraulic Model (R-THYM), a digital twin that assists with the design process by allowing you to easily play out what-if scenarios and try various configurations with graphical components focused on water and energy. I also developed the Integrated Agricultural and Municipal Demand-Delivery (IAMDD) model. This platform ties municipal and agricultural demands to water delivery in a single planning tool to assist with water rights, irrigation scheduling, and operational decisions around changing climate forces.

In addition to these core products, I offer custom web-enabled GoldSim models. While most GoldSim applications run efficiently on a desktop, bringing them to the web offers unique advantages. By integrating online resources like GIS mapping and GHCN climate data directly into the web interface, we can deliver agile models that present complex information in a way that is highly understandable and useful to your specific audience.

You will also find custom hydraulic models built with EPANET. These serve as great examples of the unique, fit-for-purpose tools I can build to address specialized problems. Feel free to look around, test drive these models, and explore the possibilities for your own water resources projects.

Real-Time Hydraulic Model (R-THYM)

Pump Station Operation Demonstration
Interactive Demo

Pump Station Operation Demonstration

A partially automated system that requires some manual interaction to keep the system running smoothly. See if you can operate the constant speed pumps and a drain valve to keep the water supply flowing.

Hybrid Renewable Energy Supply
Interactive Demo

Hybrid Renewable Energy Supply

Determine the appropriate mix of renewable energy and battery size needed to power a constant speed pump that delivers water to a small tank for irrigation supplies. Run the model for 24 hours to ensure that you can prevent the tank from going dry during the irrigation period.

Pumped Storage
Interactive Demo

Pumped Storage

This closed system demonstrates how you can generate electricity using a hydropower turbine during the peak energy price hours and pump water to the tank during lower price hours.

Analyzing Pressure Surge in Transmission Main
Interactive Demo

Analyzing Pressure Surge in Transmission Main

Simulate water hammer effects caused by rapid valve closure at the end of a long transmission main. Experiment with different closure rates to minimize pressure surges, prevent cavitation, and protect the pipeline from damage.

Real-Time Surge Analysis: Looped Pipe Network
Interactive Demo

Real-Time Surge Analysis: Looped Pipe Network

Watch R-THYM's high-fidelity Method of Characteristics (MOC) engine in action. This model showcases dynamic transient wave propagation and pressure oscillations across a complex looped system—all running natively in the browser.

Integrated Agricultural & Municipal Demand-Delivery Model (IAMDD)

Integrated Water Networks

Integrated Agricultural and Municipal Demand and Delivery (IAMDD) Model

Synthesize GIS, weather data, and complex pipe network hydraulics to accurately simulate regional water delivery for mixed agricultural and municipal demands.

IAMDD Example Model: Strawberry Farm
Interactive Demo

IAMDD Example Model: Strawberry Farm

A hypothetical strawberry farm being irrigated with microsprinklers. This example demonstrates how to configure and run an IAMDD model without building one from scratch.

Web Enabled GoldSim Models

GoldSim Model - IWRM
Stochastic Dynamic Simulation

GoldSim Model - IWRM

A demonstration of executing a complex, stochastic GoldSim model securely in the cloud and delivering the statistical results directly to a highly interactive web dashboard.

GoldSim B-SOAR Simulation
Stochastic Dynamic Simulation

GoldSim B-SOAR Simulation

A web-integrated GoldSim model demonstrating performance assessment of a radioactive waste repository. This interface provides dynamic interaction with the stochastic B-SOAR simulation engine, allowing for real-time adjustments to waste form settings and immediate visualization of multi-pathway dose distributions and radionuclide inventory results.

Probabilistic Snowmelt Watershed Runoff
Stochastic Dynamic Simulation

Probabilistic Snowmelt Watershed Runoff

Define the watershed and climate data using automatic delineation and fetching of GHCN datasets with analysis before running the model. This GoldSim model uses the stochastic weather generator WGEN to drive hydrological models such as a snow accumulation and melt model with the Australian Water Balance Model (AWBM).

Hydrologic and Hydraulic Tools

Hydraulic Architecture

Pump Dynamics Simulator

Real-time differential solver tracking dynamic head variables, parallel pump mechanics, and variable flow interactions.

Hydraulic Architecture

EPANET Scenario Model

An interactive, web-based platform for running EPANET water distribution models. Operators can intuitively evaluate localized demand changes and instantly visualize resulting pressure gradients across the municipal grid.

Climate Time Series Explorer
Hydrology & Climate Analysis

Climate Time Series Explorer

A unified utility to easily find, download, and analyze historical daily climate time-series data from NOAA GHCN-D. It provides geographic search, data filtering, and advanced statistical analysis for both precipitation and temperature—including extremes, distributions, and long-term Mann-Kendall climatic trends.

Riprap Channel Design
Hydraulic Architecture

Riprap Channel Design

Calculate stone sizing for channel armoring based on Isbash methodology and velocity profiles. This interactive tool features real-time animations that dynamically update the visual shape of the channel, water depth, and riprap thickness as you adjust the design parameters.
