A method for analysing longitudinal variations in cross-sectional shape and channel slope is developed and demonstrated with an application to the Wimmera River, Australia. The method involves characterising the geometry and spatial location
of individual cross-sections using 4 parameters and then conducting statistical analyses of the parameters from a set of cross-sections. The application to the Wimmera River identifies longitudinal trends and variability in cross-section characteristics
This paper discusses some of the results of studies on karst geomorphological process response to climate and other environments in the Hongshui River Basin of South China as well as Beijing and Shandong areas of North China. Based upon the water
chemicals with runoff data of 124 karst springs and underground rivers in the Hongshui River Basin, the rates of solutional denudation were calculated by means of the simplified Corbel's formula. The karst solution is a complex response process
Estimation of snow and glacier-melt contribution to the Chenab river, western Himalaya
A ten-year (1982-1992) assessment of the total water budget of the Chenab River at Akhnour. About 70 percent of the basin area is covered with snow in March/April which is reduced to ca. 24 percent in September/October. - (DWG)
Paleohydrology and paleoclimate of the past 33,000 years at the Tamanduá River, Central Brazil
Deposits of the Tamanduá River contain evidence for 4 major paleohydrologic stages in the last 33,000 years. Using these deposits, the AA. reconstruct paleohydrological conditions and infer relations among landform processes, paleohydrological
Spatial patterns of historical overbank sedimentation and floodplain evolution, Blue River, Wisconsin
This paper examines the processes that influence spatial patterns of historical floodplain sedimentation and the implications for the evolution of floodplains in the Blue River watershed, Wisconsin. The storage of historical overbank sediments
Anthropogenic impact on water conditions (Vistula and Oder river basins)
. As an effect of this hydro-economic activity of man the natural cycle and balance of hydrological processes have often been interrupted. This is particularly visible in the modification of the hydrographic network : changes in river routes, the elimination
of some rivers and lakes, the loss of marsh areas and the regulation of outflow conditions in rivers.
Structure of the solute yield in the Vistula river basin with special regard to anthropogenic components
Anthropogenic impact on water conditions (Vistula and Oder river basins)
concentrations from data for the years 1976-1985, and mean discharges of river waters. For 20 selected larger catchments of the Vistula tributaries the AA. also calculated the total solute yield, i.e. including the sources of municipal and industrial wastewater
The characteristics of overbank deposits associated with a major flood event in the catchment of the River Ouse, Yorkshire, UK
A high magnitude flood event in the catchment of the River Ouse, UK, in January and February 1995, afforded a valuable opportunity to collect representative samples of the associated overbank sediment deposits at various locations throughout
in the local rivers in order to investigate the particle size selectivity of conveyance losses during overbank flood events.
Floodplain sedimentation and sensitivity : summer 1993 flood, upper Mississippi River valley
This paper elaborates on the pattern of overbank sedimentation associated with the point failure of artificial levees during the summer 1993 flood in the upper Mississippi River basin. These failures inundated clearly delineated, 16 to 179 km2
in the upper Mississippi River valley to the summer 1993 flood by comparing the response of the floodplain in the study reach to that of the floodplain reaches further downriver.
Nonlinear downstream changes in stream power on Wisconsin's Blue River

Spatial characteristics of stream power are examined along 4 stream reaches through the Blue River watershed in southwestern Wisconsin. This study contributes to the general problem of explaining the spatial structure of energy expenditure
Fingerprinting the origin of fluvial suspended sediment in larger river basins : combining assessment of spatial provenance and source type
and source type information for contemporary suspended sediment fluxes from the upper and middle reaches of the River Exe and River Severn, UK. A nested approach is adopted, whereby sediment origin is initially addressed in terms of the distinct spatial zones
Large woody debris and river geomorphological pattern : examples from S.E. France and S. England
This paper contributes to the evaluation of the geomorphological significance of large woody debris, LWD, in European rivers. It provides a context for this evaluation through an analysis of the international literature on LWD. It then presents
an analysis based upon semi-natural hydrosystems in S.E. France and S. England of different geomorphological pattern or type. Finally, some recomendations for management based upon geomorphological river types are presented.
The internal structure of scrolled floodplain deposits based on ground-penetrating radar, North Thompson River, British Columbia
This study examines the channel-scale, 3-D structure of a scrolled floodplain of a meandering river, specifically a square kilometer of the North Thompson River Floodplain near Kamloops, British Columbia. Sedimentologic data are acquired largely
Use of fallout 137Cs in investigations of overbank sediment deposition on river floodplains
floodplain sediments will be discussed, and the primary factors influencing the distribution of Cs 137 in the sediment will be examined. The results obtained from a case study of a floodplain reach of the River Stour, Dorset, UK, will be used to illustrate

Fluvio-coastal interactions are examined on a progradational sand, and mixed sand and gravel beach sequence between the Ashley and Kowai rivers, Pegasus Bay, New Zealand. This coastal system presents an example of a wave-dominated environment
energetic enough to deal with the sediment supply derived from the rivers, but where the coast is still prograding. Its provides an opportunity to examine a prograding sand and MSG beach sequence in a non-downdrift situation.
First data on the coastal dynamics and the sedimentary characteristics of the area influenced by the River Irminio basin (SE Sicily)
This paper examines the drainage basin of the Irminio River, in the southern sector of Sicily, and concerns the evolution of its delta, which became submerged in the recent geological past and in the present historical period. The evolution
