Changes in riverine hydrography and reduced aquifer recharge due to projected climate changes in arid and semi-arid regions are the main issues of water supply, especially in the Nile Delta, Egypt. Continuous degradation results from reduced Nile water flow, poor management of groundwater extraction, and human activities throughout the Nile’s course and drainage channels. Contamination of this water with heavy metals and dissolved organic solids reduces the quality of this water, which increases the price of treatment. River Bank Filtration (RBF) is a water treatment technology used for improving the quality of drinking water taken from polluted rivers where abstraction wells are installed on the banks. This study was applied to the RBF site at Embaba, Nile Delta, Egypt using the numerical code MT3D. The study was simulated and calibrated for the current situation and number of scenarios to investigate the effect of climatic changes on RBF sustainability. Four scenarios were simulated to identify and estimate the RBF portion and the total water travel time from the river to the wells. The first scenario involves a reduction in river stages, the second a decrease in aquifer recharge, the third a combination of the first two scenarios, and the fourth scenario combines scenarios 1, 2, and 3. The results indicate that the RBF portion decreased from 67.42% in the base case to 35.46% and 64.99% with a reduction in river stage by 75% from the base case and a decrease in aquifer recharge from 182.50 (base case) to 50 mm per year, respectively. Moreover, the RBF portion increased to reach 87.75% with a reduction in the General Head Boundary of 75% from the base case, while the combination of the three scenarios decreased the RBF portion to 67.24%. Finally, the water supply systems in arid and semi-arid regions should be extended by installing and operating RBF facilities to manage the negative effects of climatic change through reduction in river stages and aquifer recharge, and increasing abstraction due to overpopulation.

Qanats represented a major technological solution for water supply in arid and semi-arid regions for millennia. Thanks to their multiple social and economic benefits, qanat-like systems spread from Iran through the Middle East in most of the arid and semi-arid regions of the world. In recent years, this valuable traditional hydraulic technology has been neglected in preservation and reuse due to the lack of management as well as the lack of legal support. This precious heritage and sustainable water supply system according to their sustainable structural features has been replaced by modern water collection and management systems such as dams and other hydroelectric infrastructures along with new pumping technologies. However, there is a growing consensus on the number of short, medium and long-term issues emerging from these systems including pollution and other environmental damages, regional conflicts, political pressures as well as their limited lifetime and structural instability. The purpose of this paper is to show qanats as an example of endangered heritage which could also represent a sustainable and clean technology. To do so, we apply a multi-disciplinary perspective integrating archaeological, architectural, sociological and conservation methodologies on a specific case study from the Tabriz region in Northern Iran: the “No-Ras” qanat.

Abstract Climate change is causing extreme recession of the mountain glaciers in Central Asia. Also increased evapotranspiration from higher temperatures in arid and semi-arid zones in Uzbekistan. Additionally, climate change has an effect increased exceptional water deficits. In such scenarios Environmental despite for a more sustainable water supply system, available reservoir capacity. Central Asia unlock watershed region, its main rivers are the Amu Darya and the Syr Darya, and its key problems of the region the efficient use of water from these rivers. Supplying water to the Khorezm oasis and Karakalpakstan, Tuyamuyin reservoir is the main water resource. With an increasing population of the region and Aral Sea ecological problems, mounting demand exists for a more sustainable water supply system. Water reservoirs of Central Asian river contribute to the improvement of water resources management in the lower part of the region and thus, play a strategic role in regional water supplication. 70% of Central Asia is arid and semi-arid regions and therefore, water supply for irrigation and population purposes is the main water sector of all Central Asian countries.

The Kafr El Sheikh Water Supply Project is a comprehensive endeavour to provide the physical and institutional resources for an effective and sustainable water supply system for 2 million persons in a developing rural Governorate in the Delta region of Egypt. The paper describes the aims of the Management Component, the institutional development of an integrated water supply and sewerage company and the main activities to-date. These include training, operational improvements, health education and finance development. Further support is required until all engineering and institutional development work has been completed.
