  • Hydropower Revenue Optimization

    Demonstration of GoldSim optimization capabilities using a simple reservoir and hydropower model

  • Mono Lake Water Balance

    Water balance model illustrating a negative feedback loop and of the use of scenarios with a dashboard

  • Adjustable Outlet Structure Discharge

    The purpose of this model is to demonstrate how GoldSim can calculate hydraulic functions dynamically.

  • Reservoir - Groundwater Interaction

    The interaction between a reservoir and a large aquifer is simulating using a simple seepage model

  • Muskingum Routing with Reservoir Elements

    Commonly used Muskingum hydrologic routing is implemented in GoldSim with Reservoir elements

  • Competing Demands on a Reservoir

    This simple model shows one method for allocating competing demands on a Reservoir.

  • Reservoir with Operating Pools

    Operating rules control outflows from a reservoir that contains operating zones divided into surcharge, flood control, conservation, and dead pool zones.

  • Controlling Reservoir Discharge

    This model explores 3 different methods of controlling discharge from a reservoir. The difference between these methods is important to understand for models that contain multiple reservoirs where discharge from one is being sent to another.

  • Dam Breach Hydrograph

    Simulate the breach in a dam as it grows through time and the resulting discharge hydrograph

  • Dam Breach Risk

    Monte Carlo Simulation of the Dam Breach algorithm to calculate risk of failure

  • Single Pool Reservoir

    Simulate the operation of a simple reservoir with an overflow spillway.

  • Hydropower Model

    This model is based on the Great Falls Project, a series of five hydroelectric dams near Great Falls, Montana.

  • Flow Between Two Reservoirs

    This simple example simulates the flow between and the levels of a two-tank system using Bernoulli's theorem.

  • Simple Reservoir Operations

    This model illustrates how several methods for calculating a reservoir discharge can be combined into a single model. The methods includes calculations based on fluid physics, lookup tables and volumetrically under low-level conditions.

  • Mass Balance Check

    Check that inflows, outflows, and changes in storage within your flow model balance.

  • Reservoir Spillway

    Example model illustrating a weir flow calculation for spillway outflow which is limited by available volume for use with long time steps

  • On - Off Reservoir Discharge

    This model demonstrates the use of a Status element to control discharges from a reservoir.

  • Rio Chama Flow Alternatives

    This model incorporates the Scenario Manager to assist with stakeholder evaluations of environmental flow alternatives.

  • Annual Recurrence Interval

    Using a submodel, calculate the recurrence interval and exceedence probability of annual reservoir spill events

  • Number of Days Which Failure Occurs

    This model counts the number of days in which some failure occurs. A failure event is defined as a reservoir overflow occurrence for any duration within a single day.

  • Forecasted Water Demand

    Calculate future, monthly water demands based on current usage and an annual projection

  • Simulating a Water Conservation Program

    Simulate the feedback loop between water sales revenues and funding a conservation program.

  • Pond Flow Network

    The purpose of this model is to demonstrate the use of GoldSim elements to represent a flow network of multiple storage elements that distribute water for water use. Water enters the system via "Inflow_Data".

  • Mine Water Balance

    Simple but realistic water balance model for a mine
