MAGNET allows users to almost instantly create a data-enabled simulation of natural groundwater conditions in the near-surface aquifer (i.e., the unconfined, water table aquifer) critical for water resource development and sustaining of groundwater-dependent ecosystems. Groundwater discharge into lakes, streams, and wetlands/springs - the major control of the long-term prevailing groundwater flow patterns – is captured through critical use of high-resolution Digital Elevation Models (DEMs). In this way, the model generates qualitatively accurate head distributions (groundwater levels) needed to understand the near-surface environment and guide more detailed analysis and monitoring. In many areas, critical observational data from massive water well datasets and scientific monitoring wells or stream gages are available for instantly evaluating the model performance.
This "Quick and Dirty" model is not meant to be complete, but rather serve as a framework for customization – it is a preliminary, default model that can be modified, extended, and further customized based on study objectives and other available (local) data, as well as user experience and expertise.
TASKS
A - Study the step by step short video tutorial under MAGNET Quick Tutorials: One Layer Flow
B - Develop MAGNET models that reproduces the simulations as depicted in the tutorial.
C - Prepare short answers to the following questions regarding a "Quick and Dirty" data-enabled MAGNET groundwater model:
- How are the bottom and top model boundaries represented? What are the flow conditions along these boundaries?
- What are the flow conditions along the lateral boundaries? What are the modeling implications?
- How is permeability of the subsurface parameterized/conceptualized?
- In what ways can the user improve the model?
