The AA. present the results of a statistical-climatological study of evaporation from the water surface in Wroclaw and its variability in the years 1946-1995. The evaporation was characterized by year-to-year variability in the annual, half-year
. with saturation deficit, solar global radiation and wind velocity. The variability of variability was taken into consideration and multi-year periods of relative stabilization and extinction of amplitude fluctuations separated and contrasted with intervals
Variability of dry sediment bulk density between and within retention ponds and its impact on the calculation of sediment yields
The objectives of this study are to make an assessment of the variability in dry sediment bulk density (dbD) between and within small flood retention ponds in central Belgium and to look at the factors controlling this variability. It will further
Riparian vegetation variability along perennial streams in central Arizona
This study clarifies linkages between fluvial hydrologic processes, fluvial landforms, and patterns of riparian vegetation populations by using a suite of geomorphic and hydrologic variables. 5 riparian vegetation populations were examined along 5
The AA. compare various real estate valuation models and the manner in which they take into account environmental variables. A reference model is compared with linear models which incorporate environmental quality notes extracted from the urban
Stage dependent variability in tractive force distribution through a riffle-pool sequence
High resolution data on spatial and temporal variability in flow hydraulics and sediment transport within riffle-pool sequences are required to improve understanding of how fluvial processes maintain these meso-scale bedforms. This paper addresses
Explaining access to human services : the influence of descriptive and behavioral variables
Cet article explore l'influence de variables descriptives, telles que les caractéristiques socio-démographiques, le lieu de résidence, la santé physique, et de variables comportementales telles que le réseau, les interactions et la mobilité sociales
Divergent evolution and the spatial structure of soil landscape variability
The spatial structure of soil variability at the landscape scale was examined on adjacent geomorphic surfaces dating from 80 to 200 ka in eastern North Carolina. The purpose was to determine whether there is evidence at broader scales
Talbot Terrace and younger Pamlico Terrace surfaces showed distinctly different patterns of spatial variability.
Variability in sediment delivery and storage along river courses in Bega catchment, NSW, Australia : implications for geomorphic river recovery
This paper analyses the catchment-wide spatial variability in the capacity of reaches to source and transfer alluvial materials. This sediment budget is extended to the estuary. The specific pattern of different types of rivers dictates the spatial
variability in sediment storage and transfer. By assessing the volume of material stored in different stores and sinks, implications for river sensitivity, sediment exhaustion and geomorphic river recovery are interpreted.

Etude des relations entre l'ENSO (Oscillation Sud/El Niño) et les débits fluviaux d'une série de bassins-versants de Patagonie. On a sélectionné la période avec le débit le plus élevé et on a utilisé les anomalies des débits fluviaux comme variables
Multicentury-scale records of carbonate (hydrographic ?) variability on the northern Iceland margin over the last 5000 years
The waters off northern Iceland are subjected to extreme hydrographic variability on annual to decadal timescales. In years when cold low-salinity water moves coastward and sea ice is prevalent (i.e., the late 1960s), marine productivity of surface
, in situ assessment of the phase relationship between the North Atlantic climate system and vegetation changes on the adjacent landmass. This demonstrates for the first time that variability in NW Iberian tree population closely tracked millennial-scale

The aim of this paper is to analyze the interannual variability which characterizes the late-winter surface air temperature in mid-latitude Europe, 45-60°N, and discuss its causes. The AA. analyze the interannual variability at its extreme
Runoff-induced sediment yield over dune slopes in the Negev Desert. 1 : quantity and variability
of a thin microbiotic crust. The runoff in turn produces erosion. The goals of this study are to study the relationship between runoff and sediment yield; to study the variability of sediment production from the crest to the base of dune slopes; to compare

Complexity in weathering profiles may reflect variability in the parent material and/or complex feedback relationships within regolith weathering systems. Because regolith formation modifies or destroys the parent material, it is difficult
to determine the extent to which variability in the weathering profile is inherited, as opposed to created by the weathering processes. The state probability function (SPF), designed to model the spatial pattern of transitions in system states, is applied
for an eastern North Carolina study area. This case study shows that intrinsic variability within homogeneous landscape units is more important in determining the total pedodiversity of the study area than is the extrinsic variability associated with measurable
