Climatic changes influence on surface water resources directly and in that way, more or less, more quickly or more slowly, by means of waterfalls, the quantity and quality of ground waters or hydrogeological resources, namely their sustenation. The conclusion about the influence of climatic changes on ground waters can be drawn on the basis of isotope research (2H, 14C) by means of which their origin and age are determined most reliably. Present investigation results of the origin and age of ground water resources at the most famous hydrogeothermal regions, as well as the sustenance forecast of their quality and reserves depending on still existing and future climatic changes will be shown in this paper.

Surface Water Resources

The calculation of water resources is the fundamental basis for legitimate utilization, effective protection, optimal configuration and optimal dispatch of water resources. Affected by climate change, economic development, and population expansion, the amount of water resources in Fengtai district, one of the central urban areas of Beijing, has undergone major changes. By comparing the results of the second investigation and evaluation of water resources (1956-1998), the paper analyzes the dynamic changes and causes of surface water resources, ground water resources and total water resources in Fengtai district in recent 61a (1956-2016). The results show that the surface water resources of Fengtai district in recent 61a is 37.978 million m3, which is 2.572 million m3 less than the previous investigation; the ground water resources is 92.959 million m3, a decrease of 13.848 million m3; the total water resources is 104.981 million m3, which is 13.830 million m3 less than the previous investigation. The gradual reduction of regional atmospheric precipitation is the main cause of the decline in surface runoff and rainfall infiltration recharge. At the same time, the continuous water-cutting of Yongding River (the biggest inflow river in Fengtai) since 2000 and the anti-seepage project implemented in 2010 further reduced the infiltration of river infiltration .

Abstract The oasis of Moghrar is located in the wilaya (province) of Naama, in the southwest of Algeria. It is well known for its Ksours, its palm groves and the good quality of its fruit and vegetables, especially the dates and their varieties. This region contains important groundwater and surface water resources. For several centuries, domestic water supply and irrigation have been carried out using traditional techniques of water harvesting such as pendulum wells and foggaras. Currently, this hydraulic heritage is meeting technical and social problems, particularly with the contribution of drilling and motor-pumps. The main issues are water table drawdown, the drying-up of water sources and degradation and decay of traditional techniques. The objective of this study is to make an inventory of all water sources in the study area, to study the impact of the contribution of modern techniques on ancestral techniques and finally to propose recommendations for safeguarding the hydraulic heritage.

Due to industrialization and over population, surface water resources are out of reach from many people so consumption of ground water is the only choice to overcome the water scarcity. Naturally, ground water is one of the significant and potable water resource but some geographical conditions and anthropogenic activities deteriorate the water quality and make it objectionable for drinking. This study was conducted to evaluate the ground water quality of Karachi, Pakistan. For this, 42 ground water samples were collected from different districts of Karachi and analyzed their physicochemical and microbiological characteristics and compared with both international (WHO) and national (SEQS) drinking water standards. Observations of the study declared that overall contamination (physicochemical and microbial) in the ground water samples of different districts of Karachi was as follow West (21%), South (20%), Central (17%), Malir (16%), Korangi (14%) and East (12%). Physical assessment of the study area declared that pH and turbidity of the ground water samples varies in the range of (6.54-7.9) and (0-1.01 NTU) which exist in the standard prescribed limit. Whereas, detection of chemical contaminants particularly TDS (457-12090 mg/L), hardness (118.8-3645 mg/L) and chloride (190-4918 mg/L) content in most of the samples were also exceed from the prescribed limit. Additionally, arsenic was abundantly present ranging from 3.52-13.63 mg/L in all collected samples of Karachi city while the concentration of cadmium (range: 0.0005-0.5012 mg/L) and lead (range: 0.201-1.817 mg/L) were also high in few samples, from the permissible limit of drinking water. Microbial contamination was also detected in which coliforms were present in the range of 0-150 CFU/100mL, which also unfit the water quality. This deteriorated ground water quality of Karachi can be improved by maintenance of proper sanitary conditions of the communities and implementation of water treatments, otherwise consumption of such water may develop serious health related consequences in the consumers.
