Scientists early Earth water world’ exposed ocean crust
2020/3/13
The Earth of 3.2 billion years ago was a "water world" of submerged continents, geologists say, after analyzing oxygen isotope data from ancient ocean crust now exposed on land in Australia. The findi...
IMPORTANCE OF INCORPORATION OF GEOSPATIAL TECHNOLOGY APPLICATIONS IN WATER RESOURCES AT GRADUATE AND POST-GRADUATE COURSES OF CIVIL ENGINEERING
water resources geospatial technology civil engineering course curriculum
2019/2/27
Water is a very crucial element to sustain life on earth. The availability of water varies both spatially and temporally. India being a water stress country, the per capita availability of water is re...

Geospatial technology Water resources Education and Training
2019/2/27
In India, water resources are managed at different levels, i.e. at central level by Ministry of Water Resources, River Development & Ganga Rejuvenation, Central Water Commission and Central Ground Wat...
Research on the fault controlling mechanism of geothermal water in Zhangzhou Basin
faulted structure Hydrothermal activity Geothermal reservoir temperature Circulation depth
2018/3/23
Fault has an important influence on the storage and movement of geothermal water. The Zhangzhou Basin is wholly located in a granodiorite rock mass. Due to the low permeability of granodiorite, faulte...
Clogging mechanism in the process of reinjection of used geothermal water: A simulation research on Xianyang No.2 reinjection well in a super-deep and porous geothermal reservoir
Xianyang Super-deep and porous geothermal reservoir Reinjection Clogging mechanism
2018/3/23
In the process of geothermal exploitation and utilization, the reinjection amount of used geothermal water in super-deep and porous reservoir is small and significantly decreases over time. This has b...
Tonga is a seismologists’ paradise, and not just because of the white-sand beaches. The subduction zone off the east coast of the archipelago racks up more intermediate-depth and deep earthquakes than...
Size fractionation of nanoparticulate metal sulfides in oxic water of Lake Teganuma, Japan
metal sulfides nanoparticle size fractionation acid volatile sulfides Lake Teganuma
2017/4/10
Concentrations of acid volatile sulfides (AVS) as metal sulfides in three different size fractions (<30 nm, 30–200 nm,
>200 nm) at Lake Teganuma were measured using a nano-filtration followed by a pu...
Source signature processing in deep water, Gulf of Mexico: comparison between deterministic deconvolution and phase conjugation
