TL;DR: The results of the analyses for stable isotopes (oxygen-18 and deuterium) indicate that the main recharge source of the groundwater in El-Dabaa is the local precipitation during the rainy season.
Abstract: The EI-Dabaa area is located on the northwestern coastal zone of Egypt and is considered to be one of the most important regions for land reclamation and agriculture. In addition, it has been selected as a potential site for constructing Egypt's first nuclear power plant.

TL;DR: Based on the analysis of the environmental isotopes of about 100 water samples, the waters in the front plain of the Tainshan Mountain are divided into eight subprovinces on a horizontal plane and four zones in a vertical plane as discussed by the authors.
Abstract: Based on the analysis of the environmental isotopes of about 100 water samples, the waters in the front plain of the Tainshan Mountain are divided into eight subprovinces on a horizontal plane and four zones in a vertical plane. The characteristics of the recharge, runoff, and water storage of different waters are discussed, and the runoffs in several sections are also calculated. Last, the tentative space-time regulation plan of the water resources is presented on the basis of the study of the environmental isotopes.

TL;DR: Isotope hydrology involves hydrologic work, particularly regarding groundwater, using both environmental and artificially introduced isotopes, some of which constitute part of the water molecule itself.
Abstract: Isotope hydrology involves hydrologic work, particularly regarding groundwater, using both environmental and artificially introduced isotopes, some of which constitute part of the water molecule itself. Natural isotopic ratio variations label natural waters in which they occur and can be monitored because the fractionation processes entailed are well understood. Resulting data can be employed in interpreting such problems as ages of particular water samples, mixing between different waters and water-rock and water-gas interactions. Natural isotope tracing can be exploited, but not controlled.
