Field testing of Glew and Ford's model of solution flute evolution
The aim of this paper is to review the Glew and Ford (1980) model of the mode and rate of solution flute evolution; to consider field evidence of the rate of flute evolution in different materials; to consider field evidence of the morphological
development of solution flutes. The occurrence of dated fluted surfaces in the field presents opportunities to test this model. The time to formation of flutes is confirmed as limestone (1000 years) > gypsum (100 years) > salt (10 years), and is consistent
The influence of slope aspect on soil weathering processes in the Springerville volcanic field, Arizona
A comparison was made between soils on north- and south-facing slopes of cinder cones in the Springerville volcanic field (SVF), in order to determine the influence of slope aspect on soil weathering processes. Accelerated rates of weathering
Location of farm woodlands in Denmark : a quantification of the results of the scheme for field afforestation in Ribe and Vejle counties
The article analyses the results of the scheme for field afforestation in Denmark. The purpose is twofold, firstly to document the afforestation on arable land. The former is documented in two counties whereas the latter is documented in three
Soils and geomorphic evidence for a high lake stand in a Michigan drumlin field
the presence of lithologic discontinuities was achieved through field observations and laboratory analysis. Lithologic discontinuities with varying strengths of expression were found in all upland soils. Upland soils typically have a sedimentologic cap
dominated by fine sands at the surface with dense, more gravelly till beneath. This occurrence suggests that upland soils in the Northport drumlin field formed from subaqueously reworked glacial till.

The study consists of the evaluation of bioclimatic conditions of Krasnobrod (south-eastern Poland). The basis of this evaluation were the multiannual data from meteorological stations as well as the results of field investigations carried out
A model, the Tillage-Controlled Runoff Pattern model (TCRP model) was developed to create a runoff pattern with flow in the direction of the plough-lines for all tilled fields within a catchment. The model needs a digital elevation model (DEM
), a landuse map and the major tillage orientation per tilled field as input. Runoff patterns created with the model could be used in any raster-based erosion model. The effect of the runoff pattern on simulated erosion patterns is shown for one field using
Weathering of a gypsum-calcareous mudstone under semi-arid environment at Tabernas, SE Spain : laboratory and field-based experimental approaches
The weathering of a Late Miocene gypsum-calcareous mudstone outcropping in large badland areas of SE Spain, under a semi-arid Mediterranean climate, was studied by means of 2 experimental approaches using both laboratory and field-based techniques

The AA. report on a field experiment studying the effects of different densities of roughness elements on sediment transport and foredune profile development. Reed stems are planted as a surrogate for vegetation at the frontal side of the foredune
and to provide validation data for the foredune development model SAFE. The AA. present a comparison between field and model results.
, their strikes fitting the shear lines of the neotectonic stress field. It is suggested that the local appearance of joints as extension fractures may have nothing to do with their orientation in the large-scale neotectonic stress field.
Direct measurement of three-dimensional flow fields and morphological evolution of the anabranches in the braided Brahmaputra-Jamuna River, Bangladesh, were undertaken to investigate the interactions between fluvial processes and anabranch
to discriminate between channels with single and multi-thread velocity fields.
Far-field test of the ICE-4G model of global isostatic response to deglaciation using empirical and theoretical Holocene sea-level reconstructions for the Fiji Islands, Southwestern Pacific
Detailed field investigations in the centre of the ancient city of Cibyra (nearly 1 km NW of the modern town of Golhisar) and its vicinity, located along a fault trace within the central part of the Burdur-Fethiye fault zone, showed geological
and faulted archaeological evidence for post-Roman earthquake surface faulting. This paper presents field observations that have been made at Cibyra and discusses the relationship between deformed relics and historical earthquakes in view of the historical
Historical aerial photographs and field observations on 5 fluvially dominated alluvial fans in southern Arizona demonstrate that channel avulsion invariably occurs where bank heights are low and often at channel bends. 5 distinct channel
. Climate is hyperarid. Results of the 2 scales of mapping (airphoto and Landsat image), supplemented by field observation north of Dakhla Oasis, further converged on an evolutionary scheme for this yardang field and a link is made between this scheme
The paleoshoreline features were first identified on RADARSAT satellite SAR imagery. The AA. investigated the features during the 1998 field season of the Joint Mongolian-Russian-American Archaeological Expedition to the Gobi-Altai region
. They identified paleoshorelines of multiple elevations in the field, which are considered to be relict beach ridges and wave-cut terraces. One hypothesis is that the high lake stands occurred during the wetter period corresponding to the Oxygen Isotope Stage 3
