1.1 GROUNDWATER INVESTIGATIONS - A
DETECTIVE STORY
Many of the basic principles of the flow of groundwater
through aquifers were established by the early
1970s. In addition, numerous analytical solutions were
available. At that time, numerical modelling of groundwater
flow was also developing although limited computing
power restricted applications. Since the 1970s
there have been significant advances in:
broadening the understanding of important flow
processes in a wide variety of aquifer systems,
developing and applying analytical and numerical
techniques to represent these flow processes.
There are many different flow processes in aquifer
systems. Inflows occur due to recharge which can result
from rainfall, runoff or groundwater-surface water
interaction. Outflows occur from natural features such
as springs and rivers and through wells and boreholes.
The actual flow processes may be complex when, for
example, a borehole takes different proportions of the
discharge from a number of laye ... read full excerpt from Groundwater Hydrology: Conceptual and Computational Models ebook
