  • Time Series Element Lookup Functions

    This model illustrates how you can reference a Time Series like a lookup function to access future or past values.

  • Time Series Data Preprocessing

    In this example, a SubModel is used to calculate average monthly rainfall amounts from a Time Series element containing rainfall rate data

  • 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.

  • Calibrate Snowmelt Runoff

    This model demonstrates the use of GoldSim's optimization feature to calibrate a snowmelt model by automatically adjusting parameters to achieve correlation between historic streamflow record and streamflow calculated in the model.

  • Reservoir - Groundwater Interaction

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

  • 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

  • Multiple Catchment Runoff

    Watershed runoff is calculated for three catchments using the same function but different inputs

  • Probabilistic Detention Pond Model

    This model presents a pond discharge versus pond capacity optimization problem.

  • HSPF in GoldSim

    This model provides a native GoldSim implementation of the Hydrological Simulation Program Fortran (HSPF).

  • Generation of a Stochastic Precipitation Record

    This model illustrates one way in which GoldSim can be used to generate a stochastic precipitation record.

  • WGEN Weather Generation Model

    Use Markov process to simulate stochastic precipitation events based on a wet state and dry state.

  • Vector HSPF in GoldSim

    This model provides a native GoldSim implementation of the Hydrological Simulation Program Fortran (HSPF) and divides the watershed into multiple subcatchments.

  • 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.

  • Rainfall Generator Calibration

    Using the GoldSim optimization module, a rainfall generator is calibrated using historical data

  • Groundwater Inflow Recharge

    This model accounts for rainfall recharge when calculating groundwater inflow in a mine pit using the Dupuit-Forchheimer equation.

  • 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

  • Triangular Unit Hydrograph

    Calculate the direct runoff hydrograph using a triangular unit hydrograph and direct precipitation

  • Flood Frequency Analysis

    Use GoldSim to perform a flood frequency analysis of daily streamflow records using the Log Pearson III distribution

  • Competing Demands on a Reservoir

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

  • 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.

  • Nonpoint Pollutant Buildup and Washoff

    This model provides simulation of nonpoint source pollutant buildup and washoff with automated calibration.
