All the models assigned to the selected category are listed below.

You can filter the list by entering keywords or phrases into the search field:

• #### 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
