introduction hydrograph of springs represents clearly all physical processes that control ground water flows inside aquifer (kuto et al., 2012: 41). study of the curve can reveal information about structure and function of aquifer, particularly hydrodynamic parameters including permeability and storage (troch et al., 1993: 228). analysis of recession curve has the advantage to calculate paramet...

Because of their importance, water springs have been the subject scholarly study since late 17th century. With development science in 19th, and especially 20th 21st centuries, they became object various fields branches science. The result diverse studies is a rich knowledge properties numerous classifications. Most basic classifications were created at beginning century, but need for interdisci...

This research aims to assess the hydrogeochemical evolution and assessment for drinking irrigation use of spring water from alluvial aquifer major karst systems in Tebessa (the northeastern part Algeria). For achieving this goal, 25 groundwater samples several springs, including thermo-mineral were examined subjected multivariate statistical analysis (principal component analysis), isotopic app...

A discussion of the effects of nutrients on springs biota and ecosystems of necessity requires an understanding of the manner and mechanism of nutrient delivery. Moreover, as evidence accumulates for particular consequences of nutrient and contaminant loading, understanding how those loads can be attenuated is crucial. This chapter focuses on nutrient loading to springsheds, with an emphasis on...

Contaminants in surface water entering karst aquifers in focused recharge can be transported rapidly through the system to discharge at springs. Such contaminants act as anthropogenic tracers of ground-water transport; analysis of their breakthrough curves as they discharge from springs allows identification and apportionment of contaminant sources, and can provide insight into aquifer structur...

Abstract Mountain block recharge (MBR) mechanisms are an important component of the water budget for many alluvial aquifers worldwide. The MBR dynamics complex, difficult to constrain, and quantification is highly uncertain. These challenges magnified in data-scarce study areas, including Cul-de-Sac Leogane plains, two Haiti’s largest aquifers, which flanked by Massif de la Selle mountain block...

Karst groundwater is an important natural resource for the water supply. The karst aquifer systems of Greece are developed within carbonate sedimentary (limestone, dolomite) and metamorphic rocks (marbles) contribute significantly to supply domestic irrigation use. They discharged through springs: submarine, coastal brackish inland freshwater springs. This review presents general characteristic...

for more than half a century isotopes have been employed as a powerful tool in studying various aspects of water resources in a largenumber of countries. however, in developing countries like iran the application of such techniques is in its infancy. the first research iniran was carried out in 1975 to identify the source of saline groundwaters in south iran, and the first national conference o...
