Hydrogeology — Problems with solutions

The Hydrogeology and Water Supply Problems in North - Central Chile !

The north-central zone of Chile is described with respect to groundwater supply problems. In this region, groundwater is almost exclusively obtained from the thin alluvium in the main transverse valleys, which descend from the Andes in those sections where the valleys cross the northerly trending "central valley." Because of the steep groundwater gradients prevailing, the groundwater resources ...

Math Problems, with Solutions

These are free online notes that I wrote to assist students that wish to test their math skills with some problems that go beyond the usual curriculum. These notes can be used as complimentary to an advanced calculus or algebra course, as training for math competitions or simply as a collection of challenging math problems. Many of these are my own creation, some from when I was a student and s...

Geomatics in hydrogeology

Design and construction of hydrogeological information systems is now a necessity. For proper functionality of these systems, it is necessary to create them in accordance with widely accepted international standards regarding geospatial information. Geomatics research tools allow for creation of basic models of hydrogeological data, consistent with these standards. The models can be based upon ...

Diffusion in Hydrogeology

The field of hydrogeology is primarily concerned with the flow of water below the ground surface and with transport, normally of solutes and heat, within that water. Many disciplines have contributed to this endeavor which requires skills from across the spectrum of science, engineering and beyond. The diffusion equation describes not only solute transport but also the flow of water, via Darcy’...
