South Africa has numerous thermal springs that represent topographically driven meteoric water migrating along major fracture zones. The temperature (40-70°C) and pH (8-9) of the thermal springs in the Limpopo Province are very similar to those of the low salinity fracture water encountered in the South African mines at depths ranging from 1.0 to 3.1 km. The major cation and anion composition o...

Springs and spring runs represent a unique class of aquatic ecosystems typified by high water clarity and relatively constant water temperature and chemical conditions. Structurally, springs are best characterized by their basin morphometry (shape and volume), their position in the landscape, and their flora and fauna. A classic aquatic food web and biomass pyramid in spring ecosystems includes...

numerous techniques have been presented by different researchers to analyze piled raft. in order to analyze pile foundation, soil can be modeled as spring, continuous medium, or porous media. pile can also be modeled as spring or continuous medium. this study includes three main stages: a short description of different types of analysis methods of pile foundation, writing a computer program bas...

in this study multivariate statistical analysis are used to characterize relationships between hydrochemical properties ofthermal and non-thermal springs. four factors for thermal waters and two for non-thermal springs were extracted basedon factor analysis. in thermal springs, the first factor showed high loading on ca, mg, na and k and this factor wasinterpreted as leaching of cations in the ...

The dynamic nature of groundwater is not readily apparent, except where discharge is focused at springs or where recharge enters sinkholes. Yet groundwater flow and storage are continually changing in response to human and climatic stresses. Wise development of groundwater resources requires a more complete understanding of these changes in flow and storage and of their effects on the terrestri...

Budapest is a major spa center with numerous thermal baths that are open to the public. Thermal spas in Budapest were first developed by the Romans and followed by the Turks, present spas were built mainly in the 19th and 20th centuries. At the city of Budapest the Danube River flows along a geological fault which separates the Buda Hills from the Great Plain. Within this fault zone in the vici...

The utilization of cold-formed steel (CFS) elements has become more popular recently, due to their cost efficiency and feasibility in construction work. Nevertheless, since such are subjected a variety complex stability issues, numerous approaches strengthening have been examined. Namely, CFS members were braced by using lightweight concrete through previous experimental program. A simplified f...

the aim of this study was to determine the best interpolation method to achieve spatial and quality distribution of springs from point view (tds) and ph in mirdeh watershed nw kurdistan province. field sampling collections was done and 268 springs of total 904 springs of whole watershed selected randomly. electrical conductivity and ph of springs was determined and 168 springs was used as train...
