Models Illustrating the Use of GoldSim for Water Management Applications

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:

  • Mono Lake Water Balance

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

  • Water Supply Trade-Off Analysis

    Use GoldSim's scenarios functionality to create a decision support framework for your next project.

  • Pumping Head Problem

    A script element is used to solve for pumping flow as a function of the total dynamic head on the pump due to headloss.

  • Markov Process Rainfall Model

    This model simulates a Markov process that randomly switches between a wet state and a dry state to simulate rainfall given some key historic statistics.

  • Australian Water Balance Model

    The GoldSim 11.0 implementation of AWBM for calculating runoff from rainfall on a watershed. This model is used for water yield and water management studies.

  • Snowmelt Runoff Model (SRM)

    This is a GoldSim impleneation of the NRCS WinSRM model for calculating runoff from a snowmelt driven watershed.

  • Muskingum Channel Routing

    Reusable model providing a modified Muskingum hydrologic routing formulation

  • Muskingum Routing with Reservoir Elements

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

  • Australian Water Balance Model (Vectors)

    Exactly the same implementation as the original AWBM except this has added capability to incorporate multiple subcatchments using GoldSim's array label sets.

  • Detention Pond With Orifice Outlet

    Simulates the inflow and outflow from a pond that controls discharge using a simple orifice in a riser outlet works

  • Runoff from Multiple Subbasins

    Simulate runoff from multiple subbasins in a watershed using AWBM in GoldSim

  • Modeling Losses through a System of Pumps

    Simple model of calculating production losses through a set of three parallel pumps each with failures and repairs

  • 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.

  • Single Pool Reservoir

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

  • 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.

  • On - Off Reservoir Discharge

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

  • 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.

  • Annual Demand Forecast Submodel

    This model uses a submodel to estimate a possible shortfall for the coming year in order to set a supply curtailment if needed.

  • 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

  • Allocator Element Priorities

    Example model providing demonstration of two different priority implementations in an allocator element

  • Municipal Water Demand

    Forecast water demand for multiple entities based on assumed starting conditions and projected rates of change such as population, water prices, and seasonal use adjustments.

  • Simple Stream Diversion Model

    This model demonstrates a simple continuous stream diversion and and a diversion operating for a fixed amount of time each week.

  • Septage Water & Solids Balance

    Simulates filling, operations, and cleaning of septic impoundments after the material is allowed to dry out followed by final disposal at a landfill.

  • Water Treatment for Acid Mine Drainage

    Example of integrating equilibrium chemical processes into GoldSim to represent water treatment for acid mine drainage

  • Simple Mass Balance

    Illustration of a simple mass balance calculation for a flow network for an inert constituent.
