Hydraulic account of underground water-supplies

Рассмотрены результаты работ по оценке запасов пресных подземных вод по источнику Кауридон. Выход источника является устьем р. Кауридон правого притока р. Геналдон и находится в 2,8 км к югу от с. Старая Саниба Пригородного района РСО-Алания. Дебит источника в разные периоды года колеблется от 120 до 243 л/сек. Каптажным устройством выход источника не оборудован. Создан лишь водосбор, позволяющий с помощью рамочного водослива производить замеры дебита источника. По источнику в 20092010 гг. были проведены гидрогеологические разведочные работы. Их целью являлось прове- дение гидрогеологических исследований на участке недр для обеспечения хозяйственно-питьевых нужд с. Старая Саниба (183,8 м3/сутки) и производственного водоснабжения (промышленный розлив), недро- пользователя (ООО Техноир ), в количестве 1544,2 м3/сутки, с подсчетом запасов подземных вод. По ре- зультатам работ произведена госэкспертиза запасов и утверждены запасы пресных подземных вод Госу- дарственной комиссией по запасам полезных ископаемых (ГКЗ Роснедра ), в количестве 1728 м3/сутки. Проведенные работы способствуют расширить представления о подземных водах Горной Осетии, в целом, и рассматривать их как достаточно перспективные для хозяйственно-питьевого водоснабжения горных сел, а также, в виду высоких качественных показателей, для промышленного розлива Are examined The results of works on the fresh underground water supplies estimation on the basis of the Kauridon source. The output of source is mouth r. Kauridon right tributary r. Genaldon is found in 2,8 km to the south from Old Saniba village of the Prigorodny disttrict of RNO-Alaniya. The debit of source in the different periods of year varies from 120 to 243 l/s. The output of source is not equipped with capping device. Is created only the drainage basin, which makes it possible with the aid of the frame spillway to produce the measurements of the source debit. On the source in 20092010 yr. hydrogeological reconnaissance works were carried out. Their purpose was conducting hydrogeological studies in the cite depths for guaranteeing the household drinking needs of Old Saniba village (183,8 m3/day) and production water supply (industrial bottling) by subsoil user (OOO Tekhnoir ), in a quantity of 1544,2 m3/day, with the calculation of the supplies of underground water. According to the results of works is produced reserves state examination and the supplies of fresh underground water by state commission for material wealth (GKZ Of rosnedra ) are affirmed in a quantity of 1728 m3/day. The carried out works contribute to enlarge ideas about the underground waters of mountain Osetia, as a whole, and to consider them as sufficiently promising for the household drinking water supply of mountain villages, and also, in the form of high quality indicators, for industrial bottling

Oasis Effect

Oases throughout the world have become important ecosystems to replenish food and water supplies. The Saharan Oases exist above the largest underground water supplies in the World. In North Africa, oases witness significantly growing populations in the oasis towns and receive thousands of tourists yearly. In oasis settlements, the majority of the population spends most of the time outdoors, in extremely hot conditions; however, few studies have investigated urban outdoor thermal comfort conditions. Therefore, this study aimed to assess thermal comfort in the Tolga Oasis Complex and test the validity of the ‘oasis effect’ concept. The methodology is based on comparative field measurement and calculation approaches in the heart of Tolga Palm Grove and in different urban settlements. Results indicate highest heat stress levels (Physiologically Equivalent Temperature (PET) index) in the oases Palm Grove in July, PET = 41.7 °C, and urban settlements, PET = 40.9 °C. Despite the significant difference between the old and new settlement fabrics, our measurements and calculation did not identify any noticeable variation of thermal comfort. Thus, the oasis effect on the outdoor thermal comfort was insignificant (during July and August 2018). Finally, the study discusses ways to improve outdoor spaces design and relieve heat stress in the settlements of Tolga.
