1) BENEFICIAL AND ADVERSE EFFECTS OF EXCAVATION OF AN INCREASING NUMBER OF GRAVEL PITS IN ALLUVIAL FORMATION TO SUPPLY BUILDING MATERIAL AND BACKFILL. 2) HYDRODYNAMIC EFFECT OF THE FREE WATER IN THE PITS. INVESTIGATIONS REQUIRED PRIOR TO PROJECT
APPROVAL. FACTORS TO ALLOW FOR AND IN-SITU MEASUREMENT REQUIREMENTS. 3) TWO RECENT CONCRETE EXAMPLES. DETERMINATION OF A PRACTICAL METHODOLOGY FOR SIMULTANEOUS WORKING OF GROUNDWATER SUPPLIES AND GRAVEL PITS.
This study examines : 1) the morphology of mound, pit, and undisturbed pedons| 2) the effect of pit/mound microtopography on soil water content and soil freezing| 3) the spatial and temporal variability of pedogenesis as indicated by cations of Fe
This paper reviews the formation and longevity of pit and mound microtopography formed by tree uprooting, and examines the importance of this process to mass wasting and soil genesis. This paper focuses on the physical environment, concentrating
This study examines and compares methods of dating pit/mound microtopography formed by tree uprooting, and provides C 14 evidence for the longevity of these landforms. The AA. use C 14 analysis of buried wood and charcoal in treethrow mounds
optimum. Nine horary pH measurements have been done donc during 26 hours in 4 solution pits developed on the emerged beach-rock. High variations are observed. These observations are the same for each pit and this corroborates the importance of biochemical
processes like photosynthesis and respiration on the pH control in the solution pits.
solution facetting, microrills, solution pits, case-hardening, micropitting or vesicular weathering and possibly surface crazing. Such microforms are the most likely representatives of a truly arid karst.
A multivariate analysis of soil pit data from 20 sites indicates three major soil groups (alkaline-neutral sands, acid sands, acid loams) in the area, each supporting distinct groups of vegetation types. On the Agulhas Plain, the hypothesis
In this paper the morphometry and morphoscopy of sand grains are considered from one of the pits of the Russian Plain (at Arapocichy). Roundness and mat are examined. The histogrammes show that the angular grains are also mat, so they have not been
Variations in the loose mantle thickness have been traced along 24 test pit profiles across convex and convex-concave slopes in the Lower Amur drainage basin. The analysis revealed that the loose mantle thickness on the slopes of mass movement
This study extends the understanding of the chemical weathering of surficial debris in alpine cirques to that operating in snowpatch hollows on valley sides. Clay mineralogy within the pits exhibits a widespread and distinct change at a depth of 15
Large-scale cross-bedded sets form a Holocene subtidal sequence exposed in a construction pit at the mouth of the Oosterschelde were used for comparative studies with present-day tidal processes. The calculated tidal current velocities, tidal ranges
The aim of the investigations was to get an idea of sources of error and their order in heavy mineral analysis. Samples have been taken from three pit-sections of a terrace-unit. The results of the investigations have been tested with statistical
