“…For this purpose, a mathematical model with exponential distribution function (Fontes 1983a;Yurtsever 1983), coupled with the hypothesis of a completely mixed reservoir, was applied. Practically, this hypothesis was proved to be satisfactory for fracture and karst aquifers (Dincer andPayne 1971 Fontes 1983a;Yurtsever 1983). The required tritium input function for this simulation was taken from the available tritium records of Adana station, which is the closest IAEA network station to the study area (IAEA 1992).…”

“…This moisture is generally characterized by low relative humidity conditions (Nir 1967;Dincer and Payne 1971;Yurtsever and Gat 1981), whereas the rains with low deuterium excess are probably more affected by moisture originating from the Black Sea (Sayin and others 1994). This equation is somewhat different from that established by Kattan (1997a) for the Syrian meteoric water line (SMWL), which is given by: The difference between the two equations is mainly reected by the low value of the intercept, which is lower in the case of the Syrian±Turkish rainfall (@14&).…”

“…The line slope (4.7) is lower than 8, a value estimated by Craig (1961) for the GMWL. The conservation of slope around a value of 8 is caused by condensation of atmospheric moisture under equilibrium conditions (Dincer and Payne 1971;Yurtsever and Gat 1981). In contrast, the low value of the mixing line slope indicates that the waters have undergone an evaporative process (Gat and Tzur 1967;Gat and Carmi 1970;Gat and Dansgaard 1972;Gat 1974).…”

Atmospheric precipitation and groundwaters from the Paleogene aquifer system in northeastern Syria (Jezireh) have been investigated using major ions and environmental isotope methods to interpret the hydrogeological features characterizing this system. Based on the chemical ratios and isotopic compositions, the groundwater bodies are differentiated into three main groups: (1) fresh, cold, and shallow groundwater; (2) brackish, thermal, and deep groundwater, and (3) an admixed groundwater. The fractions of deep thermal water in the total discharge of admixed groundwaters were estimated and the elevations of recharge zones for the Paleogene aquifer were determined. Based on tritium content in atmospheric precipitation and by adopting a model with exponential time distribution function, the mean residence time of groundwater is evaluated. Radiocarbon groundwater ages were calculated and corrected according to the most commonly used models. The extensive declining of major karst springs discharge in the Ras Al-Ain area is the consequence of a severe groundwater pumping from the Paleogene aquifer. The remaining groundwater resources in this aquifer are subject to be exhausted in the future years, in the absence of any real rational treatment and suitable management strategies.

ÖzetTürkiye'nin güneybatısında bulunan Çöl (Haydarlı/Afyon) Ovası 465.56 km 2 'lik bir drenaj alanına sahiptir. Ovada Anamas-Akseki Otoktonu, Beyşehir-Hoyran-Hadim Napları ve örtü kayalarına ait birimler yüzeylemektedir. Bölgede en önemli akifer Kuvaterner yaşlı alüvyondur. Yeraltısuyu akım yönünün ovanın güneyine doğru olduğu görülmektedir. Çöl Ovası'nda en önemli sorun yoğun tarımsal faaliyetler sonucu aşırı yeraltısuyu çekimidir. Çöl Ovası'nda hidrojeokimyasal değerlendirmeler için yeraltısuyunun kalite, köken ve kirlilik analizleri yapılmıştır. Ovada yeraltısuyunun genel olarak Ca-HCO3 hidrojeokimyasal fasiyeste olduğu belirlenmiştir. Çalışmada yeraltısularının sulama suyu olarak kullanıma uygun olduğu tespit edilmiştir. Ovada yeraltısuları için en önemli kirletici unsur tarımsal faaliyetlerdir. Bu durum, ova genelinde yeraltısularında nitrat içeriklerinin artmasına neden olmuştur. Ayrıca, yeraltısularının Al, As, Cr, Cu, Fe, Mn ve Pb gibi ağır metal içerikleri incelenmiştir. Ovada Al, As, Fe ve Mn içeriklerinin bölgesel ölçekte içme suyu standartlarını aştığı tespit edilmiştir. Bu artışlar jeojenik ve antropojenik etkenlerden kaynaklanmaktadır. Yeraltısularının kökensel değerlendirmelerinin yapılabilmesi amacıyla izotop içerikleri belirlenmiştir. Yeraltısularının izotop değerleri meteorik kökenli suları temsil etmektedir. Hydrogeological and Hydrogeochemical Assesment of Çöl (Haydarlı/Afyon) Plain)Keywords Çöl plain, Hydrogeology, Hydrochemistry, Afyon. AbstractThe Çöl (Haydarlı/Afyon) plain which is located in the southwest of Turkey have 1505 km 2 watershed area. Anamas-Akseki autochtonous and units belonging to allochthonous Beyşehir-Hoyran-Hadim nappes and cover rocks units are outcropped in the investigation area. The most important aquifer is Quaternary aged alluvium. General groundwater flow direction is towards to south of the plain. In the Çöl plain, it has been excessive drawing of groundwater owing to the agricultural activity. In order to find out the hydrogeochemical features, surface and groundwater samples taken from representative locations in the Çöl plain were analyzed for the hydrogeochemical features. Groundwaters have determined the Ca-HCO3 facies in plain. Groundwaters are suitable for usage as irrigation water in the plain. Agricultural activity is most important pollution in the plain. Nitrate content is increased because of agricultural activity in the research area. Besides, heavy metal contents of groundwater such as Al, As, Cr, Cu, Fe, Mn and Pb were also researched. Al, As, Fe and Mn concentrations of groundwater have exceed the maximum allowable limits of drinking water standards as locally. These increases originated from geogenic and antropogenic factors. The isotope contents of groundwaters were determined to the genetic evaluation. Heavy isotope contents of groundwaters are represented meteoric origin.© Afyon Kocatepe Üniversitesi GirişSu kaynaklarının istenilen zaman, mekan, kalite ve miktarda teminine yönelik olarak yaşanan sıkıntılar konuya ilişkin dünya çapında sürdürül...

“…Environmental tracer data also have shown that mean transit times of groundwater discharging from springs in karstic systems are highly variable. For example, using tritium ( 3 H) alone or in combination with data for chlorofluorocarbons (CFCs) and sulfur hexafluoride (SF 6 ), mean transit times were estimated to be several years or less for high-elevation springs in Virginia, USA , 10-30 years for spring waters in areas where the Upper Floridan aquifer (UFA) is unconfined (Katz et al 2001), and 20-100 years for karst aquifers discharging to springs in southwestern Turkey (Dincer and Payne 1971). Springs provide a unique opportunity to determine groundwater flow characteristics, thus enabling a better understanding of contaminant movement in complex aquifer systems.…”

Large karstic springs in east-central Florida, USA were studied using multi-tracer and geochemical modeling techniques to better understand groundwater flow paths and mixing of shallow and deep groundwater. Spring water types included Ca-HCO 3 (six), Na-Cl (four), and mixed (one). The evolution of water chemistry for Ca-HCO 3 spring waters was modeled by reactions of rainwater with soil organic matter, calcite, and dolomite under oxic conditions. The Na-Cl and mixed-type springs were modeled by reactions of either rainwater or Upper Floridan aquifer water with soil organic matter, calcite, and dolomite under oxic conditions and mixed with varying proportions of saline Lower Floridan aquifer water, which represented 4-53% of the total spring discharge. Multiple-tracer data-chlorofluorocarbon CFC-113, tritium ( 3 H), helium-3 ( 3 He trit ), sulfur hexafluoride (SF 6 )-for four Ca-HCO 3 spring waters were consistent with binary mixing curves representing water recharged during 1980 or 1990 mixing Résumé D'importantes sources karstiques du Centre-Est de la Floride aux USA, ontétéétudiées par multitraçage et par des techniques de modélisation géochimique, pour mieux comprendre les directions de l'écoulement souterrain et les mélanges entre les eaux souterraines phréatiques et profondes. Les eaux de source sont du type Ca-HCO 3 (six), Na-Cl (quatre), et mixte (une). L'évolution de la chimie des eaux du type Ca-HCO 3 aété modélisée par réactions entre l'eau de pluie et la matière organique des sols, la calcite et la dolomite, dans des conditions oxydantes, et par mélange avec des proportions variables de l'eau saline de l'aquifère du Bas-Floridien qui représente 4 a 53% du débit total de la source.Les Resumen Se estudiaron manantiales kársticos grandes en la parte centro-oriental de Florida, USA utilizando técnicas de modelizado geoquímico y multi-trazadores para un mejor entendimiento de trayectorias de flujo de agua subterránea y la mezcla de agua subterránea profunda y somera. Los tipos de agua de manantial incluyeron Ca-HCO 3 − (seis), Na-Cl (cuatro), y mezclada (una). Se modelizó la evolución de química de agua para las aguas de Hydrogeology Journal (2006) los manantiales Ca-HCO 3 − mediante las reacciones de agua de lluvia con la materia orgánica del suelo, calcita, y dolomita bajo condiciones anóxicas. Los manantiales con Na-Cl y mezclados se modelizaron mediante reacciones ya sea de agua de lluvia o agua del acuífero Floridano Superior con materia orgánica del suelo, calcita, y dolomita bajo condiciones anóxicas y mezclando con distintas proporciones de agua salada del acuífero Floridano Inferior, lo cual representó entre 4 y 53% de la descarga total de los manantiales. Los datos de trazadores múltiples [clorofluorcarbono CFC-113, tritio ( 3 H), helio-3 ( 3 He trit ), hexafluoruro de azufre (SF 6 )] para cuatro manantiales Ca-HCO 3 − fueron consistentes con curvas binarias de mezclado que representan agua recargada durante 1980 o 1990 que se mezcló con un componente más viejo libre de trazadores (reca...
