Mezometeorologicka a mikrometeorologicka charakteristika teploty vzduchu v clenitom reliéfe. (Mesometeorological and micrometeorological characterization of air temperature in varied relief)
The four expedition measurements in the years 1975 to 1977 in the Mostenik river-basin at 11 points in two cross and one longitudinal profiles give the characterization of temperature differences occuring in two m height as a result of different

In this paper, the AA. use analytical methods and numerical models to explore 2 specific questions : how reliable is Playfair's law in the vicinity of junctions particularly when uplift rate (or baselevel lowering rate) varies in time ? and what
are the implications for the associated parameter estimates ? Because incision rates vary within the basin, Playfair's law only holds exactly at the junctions. These effects are more important when slopes are measured over longer distances. Finally, measurement

Sediment-sorting processes related to varying channel-bed morphology were investigated from April to November 1993 along a 1-km pool-riffle and step-pool reach of North Saint Vrain Creek, a small mountain stream in the Rocky Mountains of northern
In order to determine the effect of bed roughness on velocity distribution, the AA. used 7 different configurations of bed roughness, with 16 test runs of varying discharge and slope for each configuration. Results indicate that velocity profile
vary with flow discharge. In parallel, an attempt is made to relate average vertical velocity profiles and derived estimates of the components of shear stress to the generally used average reach values derived from energy gradient and mean flow depth.
The aims of this paper are to show how the widths of channel, floodplain, fan, terrace, colluvial, and glacial deposits vary along the profile and to assess the impacts of internal and external controls on these variations. The paper begins

The advance mechanism of longitudinal dunes in Physics of desertification.
Results of field work studying the mecanism of movement and advance for longitudinal dunes shows that wind that encounters longitudinal dunes obliquely is deflected on the lee flank and blows along that flank parallel to the crest line.

The rivers in Japan and Taiwan lying in a warm-humid climatic region and on island arcs with violent crustal movement have markedly large erosion rates and are today not at grade. Nevertheless most of the longitudinal profiles of the rivers
are described by either exponential or power functions, both of which have been proposed for graded rivers. Using the coefficients of the functions best fitting to the longitudinal profiles, the stages in morphological development of the profiles are discussed

This paper, with CCA and other quantitaive methods, compares the characteristics of vegetation distribution in the longitudinal and transverse directions across the landscape in the Gurbantunggut Desert, and discusses the response to spatially
varying gradients of environmental factors, such as landform morphology and soil physical and chemical properties. Thus, this paper aims to provide ecological understanding of the relationship between the vegetation patterns and environmental factors

This paper examines the characteristics of small offset streams in Japan, through the analysis of planform channel course geometry and longitudinal profiles measured in the field. Some configurations characteristic to the deformation types still
remain in their longitudinal profiles with various degrees of fluvial adjustment as long as the fault activity continues.
