  • Catchment area;Watershed ; Farming;Agriculture ; Land use ; Photointerpretation ; Soil conservation ; Soil erosion ; South Africa
  • Stereoscopic air photographs from 1944/5 and 1976/81 were used to identify eroded areas in the Tugela catchment area. No difference was detected between African and European lands and the extent of erosion declined. - (AJC)
  • The relationship between catchment and hillslope properties implications of a catchment evolution model
  • Catchment area;Watershed ; Drainage network ; Mathematical model ; Model ; Rill wash;Runoff ; Soil erosion
  • This paper will review a mathematical model that simulates the physical runoff and erosion processes that are believed to occur on hillslopes and channels of a typical catchment. More importantly, the model is able to explicitly model the growth
  • and evolution of the channel networks that form the drainage backbone of the catchment.
  • The dispersal of metal minig wastes in the catchment of the river Geul (Belgium-The Netherlands).
  • The study area covers the catchment of the transboundary river Geul in Belgium and the Netherlands. The fluvial dispersal of mining wastes has caused enhanced concentrations of lead, zinc and cadmium in aquatic sediments and flooplain soils in both
  • countries. The objective of this study is to investigate quantitatively the dispersal of metal mining wastes in this catchment. - (AGD)

  • A catchment-scale assessment of anabranching in the 143 000 km2 Fitzroy River catchment, north-eastern Australia
  • . Anabranching channels have a tendency towards shorter link lengths, lower sinuosities and lower valley slopes and occur at larger catchment areas than single channels. These differences are discussed in the context of published hypotheses regarding the cause
  • In this study of the Fitzroy River catchment, the AA. investigate whether an analysis of easily available remotely sensed and DEM data can provide useful information about the occurrence and the styles of anabranching. They present an initial
  • analysis of anabranching in the Fitzroy River using maps and satellite imagery, in which 3 distinct anabranching morphologies that occur in different regions of the catchment are described. This is then followed by a catchment-scale analysis of all channels

  • catchment, discharge, sediment and solutes calculations for 2 additional subcatchments, the assessment of water and solute transport for the total N catchment and comparisons with the most polluted neighbouring area,ie. with the Zala catchment. The AA
  • Lake Balaton being a recreation area of international significance, research on the influx of sediments and solutes as well as on pollution and eutrophication is very important. Methods include a detailed analysis of a test area typical for the N

  • Hydrogeological studies of springs in the catchment of the Gaula River, Kumaun Lesser Himalaya, India
  • Catchment area;Watershed ; Deforestation ; Himalaya ; Human impact ; Hydrology ; India ; Mountain ; Soil erosion
  • One result of deforestation in the catchment area of Lesser Himalayan Gaula River area in south-central Kumaun has been the drying up of some springs and the reduced discharge of others. The AA. develop a typology of springs and measure their water
  • Predicting catchment sediment yield in Mediterranean environments : the importance of sediment sources and connectivity in Italian drainage basins
  • Forecast ; Italy ; Landslide ; Mediterranean area ; Model ; Sediment budget ; Soil erosion ; Watershed
  • From reservoir sedimentation data of 44 Italian catchments, it appeared that there was a (non-significant) positive relation between catchment area and sediment yield. This is in contrast to what is generally expected from the theory of decreasing
  • sediment delivery rates with increasing catchment area. Furthermore, this positive relation suggests that processes other than upland erosion are responsible for catchment sediment yield. Here, the AA. explore the potential of the Factoring Scoring Model
  • A comparison of SRTM and high-resolution digital elevation models and their use in catchment geomorphology and hydrology : Australian examples
  • hydrological and geomorphological statistics and descriptors such as the area-slope relationship, cumulative area distribution and hypsometric curve, along with Strahler and networking statistics. Care must be used for quantitative assessment of catchment
  • hydrology and geomorphology, as in all cases SRTM-derived catchment area is incorrect and smaller digital elevation grid sizes are required for accurate catchment-wide assessment.
  • The AA. examine the Shuttle Radar Topography Mission (STRM) data for 3 catchments in Australia over a range of climates, geology and resultant geomorphology. The SRTM data are compared with high resolution digital elevation models. The AA. use basic

  • Application of catchment scale sediment delivery model INCA-Sed to four small study catchments in Finland
  • Finland. The Mustajoki and Haarajoki catchments are forested and only 10% of the area is under cultivation. In the Luhdanjoki catchment agricultural fields cover 40% of the area. The fourth study site, the Savijoki catchment, represents an intensively
  • The aim of this study was to test the applicability of the novel catchment scale erosion and sediment delivery model INCA-Sed to Finnish catchments. Three of these, the Mustajoki, Haarajoki and Luhdanjoki, are headwater catchments located in central
  • cultivated area in south-western Finland. The INCA-Sed model was able to capture both the correct magnitude and seasonal behaviour of suspended sediment concentrations in the rivers, as well as the correct magnitude of the sediment load derived from different
  • Fluvial dynamic processes in forested catchment areas in the Central German Uplands
  • The activity of fluvial morphodynamic processes in gullies is investigated in order to get information on the actual erosion and denudation rates as well as on the genesis and development of gullies. For this purpose, four small research catchments
  • were chosen in the wooded uplands of the Odenwald and the Taunus and equipped with gauging stations. The influence of different environmental catchment conditions on the geomorphodynamic processes is examined by means of a comparing analysis
  • Holocene alluvial sediment storage in a small river catchment in the loess area of central Belgium
  • erosion intensities and colluvial sediment storage from previous work in this catchment are supplemented with the new data to establish a preliminary sediment budget for this river catchment.
  • Hydrological structure and erosion damage caused by concentrated flow in cultivated catchments
  • by topography or by agricultural practices; 2) rill length is a major component of rill volume variability on a catchment scale; 3) rill cross-sectional areas are controlled by the size of upslope runoff-contributing areas connected to the corresponding channels
  • This study analyses the between-catchment variability of rill volumes produced by concentrated flow erosion during winter in the northern part of the Paris Basin. The working hypotheses were that 1) runoff concentrates along channels determined
  • . Catchment erosion rates were estimated by adding together the predicted rill volumes for each segment within the catchment.
