Correlating specific conductivity with total hardness in gypsum karst waters
The aim of this paper is to evaluate how adequately simple specific electrical conductivity measurements in the field may be used to estimate amounts of dissolved gypsum and total disolved solids in gypsum karst areas. To illustrate the foreign ion
A high density of settlement (150 inh./km) is a further specific characteristics connected with strongly industrial character of the region. High level of urbanization has accelerated due to demographic transformation and centralization of housing
Critical specific stream power in gravel-bed rivers
Experiments with marked pebbles were carried out on different sized rivers of the Belgian Ardenne (catchment areas varying from less than 1 km2 to 2700 km2). Specific stream power required to cause bedload movement was evaluated and critical values
were obtained. Three types of relationship between critical specific stream power and grain size were established.
Location-specific cumulative distribution function (LSCDF) : an alternative to spatial correlation analysis
The paper presents an approach for spatial correlation analysis for count variables by comparing their cumulative spatial distributions. Using the concept of LSCDF in classical statistics, it shows that location-specific and its associated K-S-like
who are the prime actors in world city network formation. This process is formally specified in terms of four international relational matrices. Through this specification it becomes possible to apply standard techniques of network analysis to world
This article presents research designed to investigate map use. Specifically, we interrogate the long-held assumption that people use maps for specific purposes and in specific ways and those purposes and ways differ from other types of graphics
Zur aufgabenspezifischen kartographischen Modellierung in der Territorialplanung, dargestellt an der Aufgabenstellung Standortverteilung der Produktivkräfte. (Problem-specific cartographical modelling in territorial planning, described
The function of the map is the main determinant of map design. With example of the problem of the distribution of stations of production forces the author illustrated a problem-specific determination of the function of thematic maps and the co
The behavior of specific sediment yield in different grain size fractions in the tributaries of the middle Yellow River as influenced by eolian and fluvial processes
Based on data from 35 stations on the tributaries of the Yellow River, annual specific sediment yield in 8 grain size fractions has been related to basin-averaged annual sand-dust storm days and annual precipitation to reveal the influence of eolian
and fluvial processes on specific sediment yield in different grain size fractions. The period from which the data were used is from 1950 to 1970 as basin-wide erosion and sediment control measures have not yet been practiced during this period, and human
Physiographically controlled allometry of specific sediment yield in the Canadian Cordillera : a lake sediment-based approach
It is generally supposed that specific sediment yield declines as the drainage basin area increases, as part of the mobilized sediment becomes trapped in the downstream cascade of storage zones. Using a larger data set of lake sediment-based
estimates of long-term sediment yield, sub-regional patterns of specific yield have been investigated for the Canadian Cordillera. The results suggest that no single model of sediment yield is adequate to describe sediment transfer processes in the Canadian
