About 15,000 wetland birds of 26 species, including several vulnerable species, have been recorded at the Yellow River source area, where an infrared camera captured rare images of snow leopards and black wolves, proving that the natural resources and ecosystem have been restored effectively since the construction of the national park.
Using arrival times and waveform modeling, they determined source parameters of earthquakes, velocity structures and discontinuity topography in and around the source area.
The petrographically and geochemically determined tectonic setting, physiography of the region and the southeast dominated paleo-current direction, as deduced from the observed sedimentary structures, all suggest Indian Craton as the most probable source area for the Tredian sediments.
The whole area including the 'water source area' and the 'water purification area' has a total area of 56 hectares.
In the assessment of the probability of rockfall propagation, the analysis with the ELA of 38[degrees] covered the area closest to the rockfall source area. This zone was defined as having a high probability of propagation, and forests in this zone were thus deemed valuable for serving a protective function (Tacnet, 2012).
Temporal changes in the depositional environment, tectonic setting, geology of the source area are frequently considered as some of the main factors controlling the characteristics of river sediments (Blank and Margolis, 1975; Anderson and Ashley, 1991; Ehrmann et al., 1992; Grobe and Mackensen, 1992; Yoon et al., 2000; Mehl et al., 2012, Prizomwala et al., 2014).
The source area for the Wajid is not clearly defined, with some geologists saying it to be from elevated eastern areas adjacent to the Hadhramaut Arch of south-eastern Yemen.
The four colors are emitted from a nearly coincident source area, which is crucial for light-beam forming in many optical applications.
According to the EPA, the agency proposes to treat thenon-aqueous phase liquid consisting of fuel oil comingled with TCE (about 40,500 cubic yards), in the one-acre source area beneath the former plant using electrical resistance heating, a technology that heats the material.
Shiyan City serves as a core water source area on the middle route of the project.
Sediment maturity is a measured by transportation distance/time from the source area to the depositional site.
