This paper compares the predictive performance of different geostatistical kriging algorithms for intertidal surface sediment facies mapping using grain size data. Indicator kriging, which maps facies types from conditional probabilities of predefined facies types, is first considered. In the second approach, grain size fractions are first predicted using cokriging and the facies types are then...

Iran's groundwater hydrochemistry has not been well understood. In this study, is evaluated using a rich, ground-trusted data sampled from 9,468 wells distributed across the country in 2011. Twelve quality parameters were analyzed each sample, resulting 113,616 over study period. Examination of anions-cations shows that concentrations sodium, calcium, chloride, and sulphate are higher than acce...

In ad 1362, a major storm surge drowned wide areas of cultivated medieval marshland along the north-western coast Germany and turned them into tidal flats. This study presents new methodological approach for reconstruction changing coastal landscapes developed from site in Wadden Sea North Frisia. Initially, we deciphered long-term as well event-related short-term geomorphological changes, usin...

The abstract should contain conspicuous acknowledgement of where and by whom the paper was presented. Abstract This paper proposes an annealing-type algorithm for generating multiple realizations of facies distributions that: (i) honor the facies data at well locations, (ii) match global...

The Pasterze is Austria's largest glacier, and it experiencing rapid downwasting retreat. A mosaic of complex sedimentary deposits has been produced in recent years which have not hitherto studied, yet provide excellent lessons into the facies distribution expected from a dying valley glacier. In this paper, new glaciological–geomorphological–geological map presented for glacier July 2021. Fres...

Physical properties of sediments are commonly used to define subsurface lithofacies and these same physical properties influence subsurface microbial communities. This suggests an (unexploited) opportunity to use the spatial distribution of facies to predict spatial variation in biogeochemically relevant microbial attributes. Here, we characterize three biogeochemical facies-oxidized, reduced, ...

We have done a geostatistical inversion of seismic data to facies probabilities. As a first step, we invert the seismic data for elastic parameters using the Bayesian AVA inversion method of Buland et. al. (2003). Next, we use an analysis of the uncertainty in the posterior distribution to filter the elastic parameters given in well logs. By comparing these filtered well logs with facies logs, ...

the study area, paykola anticline, is located in the southwestern part of kermanshah province. the aim of this research is to evaluate the geomorphological indexes of active tectonics in paykola anticline as well as to study the effect of tectonic in the form and direction of geomorphological landforms. to achieve the aim of study, the lithological and tectonic characteristics of study area wer...

of geomorphological investigation. However, the process of this analysis itself is in fact still unclear, even though geomorphologists use it very often. Therefore, a firm concept of geomorphological analysis has been postulated according to a proposal published by Urbánek (2000a, b) and applied to geomorphological research of previously glaciated areas in the Šumava Mts. (the Czech Republic). ...
