Created as a supplemental text for use in junior/senior-level undergraduate courses in Hydrogeology, environmental science, geophysics, and groundwater engineering; assumes a quantitative background in math, physics and/or engineering. This practical and succinct guide on mathematical Hydrogeology derives and connects the various mathematical flow equations to actual physical situations. Making the derivation and mathematical rationale clear on the first read-through, it offers a firm foundation in groundwater flow, and provides the analytical “jolt” students need to understand and tackle such subjects as watershed processes and numerical modeling.
