Mangroves in gulf of Kachchh, Gujarat, India has been studied for grain size spectrum and textural parameters namely phi mean, standard deviation, skewness and kurtosis. Grain size spectrum shows a marked variation in the upstream riverine input stretch. Variation of energy conditions is controlled by the fluvial profile in the channel. Textural pattern shows complicated profile as a result of ...

The current low temperatures and pressures at the martian surface are not conducive to the stability of liquid water; hence the discovery of recently active, fluvial-like gullies [1, 2] presents an apparent paradox: how can these fluvial landforms have occurred if water is not stable at the surface? To approach this problem we have compared the morphometric properties of gullies in various sett...

The presence of valley networks and open-basin lakes in the late Noachian is cited as evidence for overland flow of liquid water and thus a climate on early Mars that might have supported precipitation and runoff. Outstanding questions center on the nature of such a climate, its duration and variability, and its cause. Open basin lakes, their interior morphology, and their associated channels p...

Degraded craters on Mars record the cumulative ffects of the complex interplay between erosion, transport and deposition by competing intermittent processes. Fommately, impact craters are instantaneous landforms common to both the Earth and Mars that are characterized by similar topography and local lithofacies. Deconvolving the signatures of individual degradation processes around young crater...

River channels and valleys have been observed on several planetary bodies in addition to the Earth. Long sinuous valleys on Venus, our Moon and Jupiter's moon Io are clearly formed by lava, and branching valleys on Saturn's moon Titan may be forming today by rivers of methane. But by far the most dissected body in our Solar System apart from the Earth is Mars. Branching valleys that in plan res...

The Paleozoic Dniepr-Donets Basin in Belarus, Ukraine, and Russia forms a major hydrocarbon province. Although well- and seismic data have established a 20 km thick stratigraphy, field-studies of its sediments are scarce. The inverted Donbas segment (Ukraine) exposes the middle Carboniferous part of the basin's stratigraphy. Here, we provide detailed sedimentological data from 13 sections that ...

The thick sequence of Quaternary sediments preserved within the northern North Sea contains important information about glacial history, palaeo-oceanographic conditions and slope stability this region during last 2.6 million years. interplay between glacial, fluvial contouritic processes can be determined from seismic stratigraphic studies. Here, horizon, attribute geomorphological interpretati...
