AquaNET V5.0.0 Release Notes

New Models/features

3D geology modeling and visualization based on Transition Probability (TP) geostatistical simulation of borehole lithologic data

TP-based hydraulic conductivity field for groundwater flow modeling (mapping to 2D or 3D models)

DataNet-based modeling - a direct link or "bridge" between DataNet and AquaNET for data import and model parameterization

Direct linkage of US streams and lakes from MAGNET Data Center (intelligent import as conceptual features / boundary conditions in a AquaNET groundwater model).

Lake water balance modeling and coupled lake-groundwater modeling , accounting for precipitation, evaporation, surface runoff, surface water inflows/outflows, groundwater seepage and infiltration, etc. Lake levels can be computed as part of this coupled groundwater-lake interaction model.

Parameter estimation tool for automated calibration of groundwater models (e.g., hydraulic conductivity, recharge, etc.) and visualization of parameter estimation analytics.

3D interactive visualization of groundwater model results (e.g., head, velocity, conductivity), TP model results, pumping wells, water well lithologies, 3D point data (e.g., well water concentrations), iso-surfaces / plumes, and the spatial framework (aquifer top and bottom surfaces).

Multiple Species fate and transport to simulate different chemical species and their interactions (based on MT3D-USGS and RT3D).

Variable-density flow simulation based on SEAWAT and MODFLOW-6.

Particle tracking integrated into the ZipModflow environment (based on MODPATH) to interactively track particles forward or backward.

New Post-Analysis modules including:
- Post analysis (visualization) of a previously created TP model
- Post analysis of particle tracking and delineation of particle path zones
- Post analysis for multiple species interactions in a constant flow field.

Aquifer Test tools for calculating drawdown and estimating aquifer properties (transmissivity, T and storage coefficient, S) based on observed drawdown data. Subtools include:
- Theis solution graphical interface
- Specific capacity analysis
- Root Mean Square drawdown analysis
- Automated estimation of T and S (based on initial guess)
- Curve matching (type curves and pump test data) - confined, leaky and unconfined aquifers
- Slug test analysis - methods: Hvorslev (1951), Cooper (1967), and Bower-Rice (1976)

Data Analysis tool for visual and statistical exploration of scatter-point data, including:
- histogram, PDF/CDF, spatial and temporal analysis of parameter values
- data density distribution visualization

- spatial interpolation (2D or 3D) using Inverse Distance Weighting or Kriging based on variogram modeling
- linear regression analysis
- outlier analysis and removal

USGS Sensor Data tool for dynamic extraction and visualization of USGS monitoring well and surface water (stream gage) sensor data.

Climate Data tool for dynamic extraction and visualization of PRISM Climate Data - gridded precipitation, minimum temperature, and maximum temperature data (daily, monthly, or annual).

Grid-based Watershed Modeling for simulation of groundwater recharge, surface runoff into lakes (for lake water balance modeling, see above) and other water balance components. Based on USGS INFIL3.0

SWAT-based Watershed Modeling for simulation of quality and quantity of surface water and other aspects of the land surface water balance. Based on USDA Soil and Water Assessment (SWAT) tool.

Video Maker tool enabling time-based screen capture and an interface for creating videos or snapshots.

New / Extended Options of Existing Features



Model Publishing / Global Model Network

AquaNET Users can now publish any SWAT-based Watershed model or ZipModflow model to the AquaNET Global Model Network (in addition to any AquaNET Groundwater model).

Additionally, the Global Model Network page now shows different types of models as different colored map markers, and a "clickable" legend has been added to allow users to filter the types of models being displayed on the map. As with groundwater, SWAT-based watershed models and ZipModflow models can be directly loaded into the correct AquaNET interface/module.

Particle Tracking

- If a 3D model is created, users can choose which computational or conceptual layer(s) the particle will appear in ("Show Particle in" option).
- An option to release particles along a 3-D surface (e.g., plume iso-surface) was added. - Particle positions and path lines can be saved for post-processing in the Post Analysis tool. Save particle file option and button.

Initial Concentration Field

An option was added to use a concentration file (e.g., generated from 3D interpolation) as the initial concentration for fate and transport modeling.

Display Settings

Several new options are available in the Display Settings tab of the Domain Attributes menu (Conceptual Modeling Tools > DomainAttr > Display Settings), including:

- Grid lines can be shown.

- New options for watershed model input/output parameters display

- New options to show multiple species fate and transport model results

- New option to overlay conceptual model features (e.g., streams and lakes from the Data Center server).

Save Model Image

At any time, a user can create and download the display contents within the groundwater model domain.

Default Model Projection

Previous Michigan state system project has been replaced with World Mercator projection.

Multiple Time Steps

Multiple time steps are allowed in a transient model. Time-step based screen capture (for video making) was also added.

Minimum Aquifer Thickness

An option was added to treat as inactive cells those cells with a thickness less than a specified percentage of maximum aquifer thickness.

Data Center Data Preview

Small '?' buttons have been added throughout the model input interfaces that allow users to preview the datasets available from the MAGNET Data Center (e.g., DEM, aquifer thickness, land use, etc.). Metadata is also provided.

Direct watershed import

Watersheds of different sizes/levels can be directly imported as a groundwater model domain or conceptual zone.

Comments about AquaNET V4 (most recent previous release)

Two important new features were added to AquaNET in the recent Version 4 release:

- MODFLOW flow packages and solvers for solving groundwater flow models in AquaNET, including MODFLOW-6, MODFLOW-USG, MODFLOW-NWT, MODFLOW-2005, and MODFLOW-2000. See more details here.

- Multi-realizatoin Monte Carlo Simulations (MCS) of flow in random (stochastic) conductivity fields. To get started, visit the Quick Tutorials 2 page.
