Abstract The paper deals with an analysis of the shear strength behaviour coarse-grained materials using large-sized direct apparatus. curve compacted material allows for determining three typical strengths, i.e. a maximum density sample tested (shear at point A), peak P), and critical achieved large horizontal movement C). Professional laboratories usually apply two different methods. first me...

Mapping in the Homs region of Syria has revealed a hitherto unrecognized staircase of at least 12 gravel terraces of the upper Orontes River. The terrace gravels overlie Pliocene lacustrine marl and have been calcareously cemented into conglomerates, sometimes interbedded with cemented fine-grained alluvium. A tentative dating scheme, based on modelling the regional-scale surface uplift that ha...

Phosphorus (P) can leach from topsoil in inorganic and organic forms. While some evidence has shown P (orthophosphate) to depth soils, less is known of dissolved (DOP). This not helped by a paucity DOP data for groundwater. We hypothesized that species would greater amounts at faster rate through aquifer gravels than orthophosphate. applied superphosphate with or without dung low P-sorption soi...

We analyzed the characteristics of red soils that are often considered collapsible soils. In this study, we examined depositional environment and lithologic characteristics, stratigraphy, conducted mechanical sieve, X-ray fluorescence, X-Ray diffraction, scanning electron microscope, fluorescence analyses optically stimulated luminescence dating. The samples were collected from gravel pits to e...

The chert gravels are a by-product of sand mining in the south Israel; reserves amount to tens millions tons and continue grow. attempts their comminution for production aggregates by conventional mechanical methods have not yet been successful due high abrasiveness, as well flaky form fracturing. This study was motivated need find an alternative method rock that would ensure aggregate line wit...

Over the last two centuries, rivers worldwide have been affected by human interventions, including dams, river training, and gravel mining. Such actions often involved fragmentation sediment starvation. In this regard, augmentation is an increasingly common restoration practice for mitigating starvation in gravel-bed rivers. However, uncertainties remain on how to better implement design such o...

The increasing demands on lateritic gravels in road construction presently make it necessary to quantify the available resources that can be used construction. This study aims estimate tonnage and valorize of north flank Mount Bangou (west Cameroon) Interpretation 48 vertical electrical soundings coupled with 20 pedological wells from five gravel sites was carried out determine thickness level....

the mode of heat and mass transfer during baking of bakery products is an important factor determining the quality of the final product. the heating rate could alter the starch properties during gelatinization and affect the quality of products after baking and during aging. sangak is a kind of iranian flat bread baked on the hot pebble gravels. the aim of this study was to evaluate the impacts...

Rapid transmission of contaminants in groundwater can occur alluvial gravel aquifers that are permeated by highly conductive small-scale open framework gravels (OFGs). This structure and the associated distribution hydraulic properties is complex, so assessments contamination risks these uncertain. Geostatistical models, based on lithological data, be used to quantitatively characterize this st...
