Define the top and bottom layers for a MODFLOW model by importing the DEM, mapping top elevations, and calculating bottom elevations with raster calculator (DEM minus 50 for layer 1).
Learn to input lithology in modflow using borehole logs for limestone, clay, and sandstone, distinguishing impermeable clay and confined versus unconfined layers.
Distinguish source and sink in groundwater modeling, identify wells as sources or sinks, and map layer ranges for existing wells using CSV data.
Add observation points to the steady-state MODFLOW model by loading a CSV of observation data, creating an observation wells coverage, defining head data, mapping to MODFLOW, and verifying locations.
Calibrate the steady state groundwater model using inverse modeling, focusing on hydraulic parameters like hydraulic conductivity, with groundwater levels as inputs in MODFLOW.
Understand transient simulation in groundwater modeling: how water levels change over time between steady states, the importance of starting head and storage, and stress periods and time steps.
Explore the plot wizard to generate time series, computed-versus-observed plots, head changes, visuals, and calibration insights, and examine flow budget versus time in a 3D grid.
Use parameter estimation with PEST to calibrate a MODFLOW groundwater model. Adjust layer values, including negative values, map flow, and iterate from an error toward 18 for better calibration.
