What & Why Groundwater Geospatial Analysis?6:40
Learn how groundwater modeling, a geospatial analysis tool, estimates flows, aquifer characteristics, and concentrations to optimize site characterization, monitoring, and remediation decisions.
When & How Groundwater Geospatial Analysis?7:37
Learn when and how to apply groundwater geospatial analysis across the project lifecycle, from a conceptual site model and EDA to building the geospatial model and optimizing sampling and remediation.
Basic Concepts of Groundwater Modeling6:43
Explore fundamental groundwater concepts, including the unsaturated and saturated zones, water table, confined vs unconfined aquifers, and the GW SDR spatial-temporal smoother, guiding conceptual site modeling and remediation.
Fundamentals

Intro to GWSDAT9:13
Explore GWSDAT, an open source web-based tool for groundwater spatiotemporal modeling that analyzes solute concentrations and elevations with penalized splines to predict plumes and support remediation.
Accessing GWSDAT9:18
Learn to access GWSDAT via online, Excel add-in, or R package, with steps to run online on a shiny server or offline in Excel or RStudio.
Data Input: Description and Requirements - Part 17:35
Explore how groundwater modeling uses three data input types in GW State — historical data, the well coordinates table, and optional GIS shape files — and follow six-field input standards.
Data Input: Description and Requirements - Part 25:27
Enter well coordinates, names, and optional aquifer associations with x and y positions and unit choices in GW State, and import shapefiles to overlay site plans.
GWSDAT Quiz

GWSDAT Excel Add-in Walkthrough7:50
Explore the GWSDAT Excel add-in for groundwater modeling with a data input template and GIS shape file integration. Use the add-in’s processing options to set outputs, non-detect handling, and resolution.
Data Input via Graphical User Interface2:54
Explore data input via a graphical user interface for groundwater modeling, using the data manager to create or import datasets with a data editor, csv/excel imports, and shape file support.
Data Input Samples (CSV and Excel files)0:59
Here you can find samples of Data Input to explore and understand their structure.
Spatial plot11:25
Explore the spatial plot tool to generate graphs and maps that analyze spatial trends in solute concentrations, groundwater flow, and napl thickness, using monitoring well data.
Plume Diagnostics6:32
Explore plume diagnostics in gw suite, including plume mass area and concentration calculations, boundary estimation, and time-series visualization; adjust porosity, thresholds, and export results to csv for remedial action optimization.
Well Redundancy Analysis6:06
Explore a well redundancy analysis in GW State to drop wells from the model, compare full and reduced results, and optimize monitoring design with updated plume diagnostics.
Time Series8:11
Explore the time series feature to analyze historical solute concentrations in wells, identifying trends, seasonality, and attenuation, with non-parametric smoothing, confidence intervals, and threshold visualization.
Trends & Thresholds8:55
Explore the trends and thresholds matrix, a traffic light plot that summarizes trend strength and exceedances across wells and solutes using colors, thresholds, and the model output interval.
Well Report & Spatiotemporal Predictions4:50
Explore the well report and spatio temporal predictions features to visualize and compare time series solute concentrations across wells, using log scale options and overlays to assess model fit.
Additional Options & Save Session5:16

Description

This course explains all the requirements to perform groundwater modeling with GWSDAT, an open-source, user-friendly, software application for modeling, visualisation and interpretation of groundwater monitoring data, developed by Shell Global Solutions and the University of Glasgow.

This is your course if you want to take your first steps with the groundwater model and:

You want to learn how to model groundwater flow and plume contamination and assess their impact on the aquifer.
You want to carry out environmental consulting in the field of groundwater remediation and impact assessment.
You want to learn how to estimate pollutant concentrations in groundwater in a site and know how to optimize your monitoring plan.

In this course, you will learn the fundamental concepts of groundwater, this will help you to understand every step needed to model using the GWSDAT software package. This tool is free for use during and after the course, and this course describes the three different ways for students to gain access to GWSDAT:

Excel Add-in Interface
GWSDAT R Package
Online Version

Practical training is one of the cores of this course so the lectures focus on practical examples and activities to present how to set up and run the tool. Therefore, the main objectives of the course are:

Provide a step-by-step walkthrough, in order to familiarize you with the software package, helping you to understand its main features and its outputs.
Prepare you with concise and comprehensive knowledge that will allow you to perform a complete groundwater modeling assessment, with a hands-on, real-world case study.

In the long term perspective, from this course, you get valuable condensed guidance that will help you during the implementation of groundwater modeling or just clarify any doubts you might have in the future.

In summary, the course presents practical explanations and examples, as well as a hands-on exercise for the implementation of groundwater Modeling using GWSDAT.
