TLDR
In this paper, three types of flow systems may occur in a small basin: local, intermediate, and regional, and the higher the topographic relief, the greater the importance of the local systems.Abstract:
Theoretically, three types of flow systems may occur in a small basin: local, intermediate, and regional. The local systems are separated by subvertical boundaries, and the systems of different order are separated by subhorizontal boundaries. The higher the topographic relief, the greater is the importance of the local systems. The flow lines of large unconfined flow systems do not cross major topographic features. Stagnant bodies of groundwater occur at points where flow systems meet or branch. Recharge and discharge areas alternate; thus only part of the basin will contribute to the baseflow of its main stream. Motion of groundwater is sluggish or nil under extended flat areas, with little chance of the water being freshened. Water level fluctuations decrease with depth, and only a small percentage of the total volume of the groundwater in the basin participates in the hydrologic cycle.read more

Interactions between groundwater and surface water: the state of the science
TL;DR: In this article, the mechanisms of interactions between groundwater and surface water (GW-SW) as they affect recharge-discharge processes are comprehensively outlined, and the ecological significance and the human impacts of such interactions are emphasized.

Choosing appropriate techniques for quantifying groundwater recharge
TL;DR: The reliability of recharge estimates using different tech- niques is variable as mentioned in this paper, and uncertainties in each approach to estimating recharge underscore the need for application of multiple techniques to increase the expected recharge rates at a site.

TL;DR: In this paper, the authors critically review recent research assessing the impacts of climate on ground water through natural and human-induced processes as well as through groundwater-driven feedbacks on the climate system, and highlight the possible opportunities and challenges of using and sustaining groundwater resources in climate adaptation strategies.
