Retence vody v povodí
  • Flood ; Flood control ; River basin ; Water retention
  • The paper discusses a broad range of flood control measures designed mainly to increase water retention capacity. It focuses on the main trends in flood control, i.e. on passive flood control and functions of dikes and retention basins. - (EN)

  • Czech Republic ; Digital elevation model ; Drainage ; Flood ; Flood wave ; Floodplain ; Geographical information system ; Lužnice river ; Model ; Stream flow ; Topography ; Water retention
  • One of main topics of interdisciplinary project NIVA – Water Retention in Floodplains and Possibilities of Retention Capacity Increase is the assessment of flood wave transformation in the floodplain. Despite the fact that the main influence
  • on flood wave transformation is flow retardation due to the flow velocity decrease, the retention in surface depressions within floodplain has been analyzed to get better overview of whole transformation process. Detailed digital relief model (DRM) has been
  • to assess the retention capacity of real floodplain with natural character which usually means higher surface retention capacity in comparison to trained rivers. - (EN)
Chemical trap efficiency of a construction site storm-water retention basin
  • Chemical trap efficiency of a construction site storm-water retention basin
  • Storm-water runoff from construction sites is an important source of nonpoint-source (NPS) pollution in an urban areas, and retention basins are widely used on construction sites to control NPS pollution. Data collected during storms for a retention
  • are to be developed to improve the chemical sediment-trap efficiency (TE) of retention basins.
Factors influencing retention of coarse particulate organic matter in streams
  • Factors influencing retention of coarse particulate organic matter in streams
  • Input of terrestrial coarse particulate organic matter (CPOM : leaves and small wood,>1 mm) adds food resources and habitat to streams. The AA. investigated retention characteristics under base-flow conditions in 65 stream reaches in pasture, native
  • forests and pine plantations in 5 contrasting New Zealand regions, using 3 CPOM analogues, namely 30 cm dowels, soaked ginkgo leaves and waterproof paper triangles. These differed significantly in geometric mean retention distance. A comparison
  • with results from Spain showed similar relationships between retention distance of plactic CPOM analogues and dicharge under base-flow conditions.

Variability of dry sediment bulk density between and within retention ponds and its impact on the calculation of sediment yields
  • 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

Natural iron precipitates in a mine retention pond near Jabiru, Northern Territory, Australia
  • Natural iron precipitates in a mine retention pond near Jabiru, Northern Territory, Australia
  • The objectives of this paper are to: a) report on the detailed characteristics of the red-brown precipitates forming the sludge plumes in retention pond 4; b) describe and characterise the red-brown precipitate coating the organic mat over the pond
Uwarunkowania retencji wybranej zlewni źródliskowej strefy krawędziowej Wysoczyzny Gdańskiej
  • Gdańsk ; Mathematical model ; Poland ; Water retention ; Watershed
  • The paper aims at identifying retention types and their natural and anthropogenic determinants in the catchment of the Potok Oliwski, especially in its headwater section, by means of Mike She mathematic model. The calculations performed allowed
  • to determine that the studied area, due to natural factors, has high retention potential, mostly in the underground zones. - (BJ)

The nature of small-scale flooding, muddy floods and retention pond sedimentation in central Belgium
  • The nature of small-scale flooding, muddy floods and retention pond sedimentation in central Belgium
  • and the site in relation to topography and landuse. This study also focuses on the use of retention ponds as a control measure, the problem of siltation of the ponds and to their potential for estimating sediment yield.
Exploring potential spatial-temporal links between fluvial geomorphology and nutrient-periphyton dynamics in streams using simulation models
  • Using a nutrient retention and periphyton growth model coupled to a dynamic geomorphic template, the AA. explore the potential role of channel shape, slope, and sediment texture on downstream nutrient retention, and attempt to determine if physical
  • changes alone can drive or influence changes in nutrient-periphyton dynamics. The overall model results suggest there is a strong potential control of both nutrient retention and periphyton biomass by channel morphology.
