Discover how geology controls groundwater flow, defines hydrogeology, and outlines unsaturated and saturated zones, recharge areas, and aquifers, while introducing specific yield and specific retention.
Explain porosity, permeability, hydraulic conductivity, and transmissivity, and how they relate to storage parameters in aquifers. Contrast confined and unconfined systems and introduce pumping tests.
Derive the groundwater flow equation from mass conservation and Darcy's law, detailing homogeneous, heterogeneous, isotropic, and anisotropic cases, and introduce the steady-state Laplace form used by MODFLOW.
Learn how to build a groundwater flow model with MODFLOW and GMS, covering model creation, calibration, validation, and predicting future groundwater levels.
Master groundwater flow modelling from the ground up using the MODFLOW code and GMS software. You will learn the fundamentals of groundwater in general and groundwater modelling in particular during this course.
No matter how much groundwater knowledge or expertise you have. Most importantly, you must be willing to learn about groundwater modelling.
During our course we will discuss interesting topics as follow:
Basics of groundwater
Theoretical background of groundwater flow
Aquifer types
Groundwater flow equation
Concept and steps of groundwater modelling
Creating Models using grid approach
Also, during our course we will use and practice on many software like:
Groundwater Modeling System (GMS): for groundwater flow modeling simulation
ArcGIS: for building the model conceptually, extract shape files and extract raster
Excel: to solve finite difference manually, to read spreadsheets and extract CSV files
Global Mapper: for extracting Digital Elevation Models (DEM), rectify images and convert projection
By the end, you will not only be able to create groundwater models by following the steps in this course, but you will also be able to understand the concept of groundwater modelling and how the MODFLOW code uses finite difference to solve the groundwater flow equation, as well as how to judge whether your model is correct or not and how to find and fix problems on your own.
So, let's start :)
