The controlling factors of the karst water hydrochemistry in a karst basin of southwestern China
Environmental Earth Sciences, 2021The Karst aquifers are usually characterized by high spatial heterogeneity in the humid tropics and subtropics, evidenced by specific landforms features (e.g., heavily fractured outcrops, sinkholes, etc.) and complex subterranean conduit networks. The marked high heterogeneity leads to the temporal–spatial variability of hydrological and hydro-chemical

Surface Waters and Groundwater in Karst
2015Karst is defined as a terrain, generally underlain by limestone or dolomite, in which the topography is chiefly formed by the dissolving of rock, and which is characterised by sinkholes, sinking streams, closed depressions, subterranean drainage and caves (Field 2002).

Karst Hydrogeology and Chemical Characteristics of the Karst Water
1995Reference has been made several times in the discussions of the karst geomorphology to the springs and underground waters of the karst areas. This chapter gives a summary review of the karst hydrogeology and the characteristics of the karst waters, particularly in relation to the geomorphology.

In the previous chapters there has again and again been a noticeable contrast between karst water and groundwater. This is a peculiarity of the German language but is nevertheless of general significance. It is a consequence of Grund’s theory of karst groundwater (1903) (see Chap. 6.2.3).

Impact of Motorways on Karst Waters
2015Impervious surfaces of road networks accumulate contaminants and pollutants, which are washed off during rain and snowstorm events into nearby waters and lands. Especially in areas with a developed traffic network, runoff from motorways is a significant source of pollution.

Hydrogeochemical analysis, statistical analysis, and geochemical modeling were employed to evaluate the impacts of coal mining activities on karst water chemistry in Niangziguan spring catchment, one of the largest karst springs in Northern China. Significant water quality deterioration was observed along the flow path, evidenced from the increasing ...

Sampling strategy for karst waters
2006To optimize sampling strategy in a small water supply in Northwestern Switzerland, event-specific sampling of turbidity and microorganisms was conducted. These data were compared with previously performed tracer tests and water quality data from routine drinking water sampling 1 to 4 times a year.

Measurements of water temperature in karst make it possible to answer numerous questions related to water circulation, its origin, retention time underground, etc. In order to determine thermal changes such measurements should be carried out with sensitive equipment, since these variations have very small amplitudes, i.e. very often, a few tenths of 1 °
