Dawn's global mapping of Vesta reveals that its observed south polar depression is composed of two overlapping giant impact features. These large basins provide exceptional windows into impact processes at planetary scales. The youngest, Rheasilvia, is 500 kilometers wide and 19 kilometers deep and finds its nearest morphologic analog among large basins on low-gravity icy satellites. Extensive ...

basins leading to tabriz plain are part of the sub-basins of urmia lake basin, which is located in the east azerbaijan province and in the north-western part of iran. the area of this basin is 5397 km2, and agriculture is one of the main sources of income for the people, which is dependent on groundwater and surface water resources. in this study, an attempt was made to investigate the basins l...

-We examined the relationships of timber harvest, stream habitat complexity, and diversity of juvenile anadromous salmonid assemblages in 14 smallto intermediate-sized basins in coastal Oregon between 1985 and 1989. Diversity (the inverse of a species dominance index) of assemblages in streams in basins with low harvest levels (<25% of the basin area harvested) was greater than in streams in ba...

The number of Martian impact basins, once thought deficient owing to a low number of impactors, has been significantly increased through the identification of structural imprints that remain even after nearly complete erasure of basin massifs. Five ancient multiringed impact basins were selected for detailed study and exhibit a systematic pattern of rejuvenation of the multiring plan through en...

Cohen, A. S., 1989. Facies relationships and sedimentation in large rift lakes and implications for hydrocarbon exploration: examples from lakes Turkana and Tanganyika. Palaeogeogr., Palaeoclimatol., Palaeoecol., 70: 65-80. Two African lakes, Turkana and Tanganyika, illustrate a spectrum of sediments and facies architectures which can occur in large rift lacustrine basins. They demonstrate cont...

Flood forecasting has been an effective way to reduce the potential flood hazards for a sustainable socio-economy. However, lack of in-situ precipitation records limited applicability with hydrologic models in poorly gauged basins. To address this problem, we aim develop framework based on merged satellite and model. The was then applied small basin upper Lequan River Basin, Hainan, China exper...

Stormwater detention basins are primarily designed to detain large volumes of storm runoff and trap suspended sediments and associated pollutants. Detaining and retaining nutrients are often not a design focus. The combination of variable moisture patterns in stormwater basins along with potential nutrient influxes may make these basins hotspots for nitrogen transformations such as denitrificat...

The proposal that climate change can drive the uplift of mountain summits hinges on the requirement that glacial erosion significantly enhances the relief of a previously fluvially sculpted mountain range. We have tested this hypothesis through a systematic investigation of neighbouring glaciated and nonglaciated drainage basins on the eastern side of the Sierra Nevada, CA. We present a simple,...

BACKGROUND Extensive intestinal metaplasia (EIM) has been reported in gastrectomies from patients dwelling in the Pacific and Atlantic basins. AIMS To compare all the results in an attempt to explain the findings. METHOD All sections from 3,421 gastrectomies were reviewed at various hospitals: 1946 in the Atlantic and 1475 in the Pacific basin. Sections with EIM showed IM encompassing one o...
