The watershed Landscape characteristics are important variables that influence surface water quality. Freshwater research and management efforts could be greatly enhanced by a better understanding the relationship between these variables and surface water quality. The major focus of this paper involved modeling relationships between watershed characteristics variables and water quality indicators...
In order to study the geochemical characteristics and medical values of geothermal water in Xi'an, 78 water samples were collected and analyzed. Results show the main factor affecting the chemical composition of geothermal water in Xi'an is the depth of the geothermal reservoir. The temperature, TDS and the concentration of SiO2 of geothermal water generally increase with the depth of geothermal reservoir...
