  • 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)

  • Applied hydrology ; Heavy metals ; Nutrient ; Ohio ; Pollution ; Rainstorm ; Rill wash ; Suspended load ; United States of America ; Water management
  • 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.

  • 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
  • used for given purposes to be able to analyze terrain depressions volumes. The methodology itself is based on analysis of areas inundated by water at different elevation levels. The method was then applied on the area of Lužnice River floodplain section
  • to assess the retention capacity of real floodplain with natural character which usually means higher surface retention capacity in comparison to trained rivers. - (EN)
  • 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)

  • 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
  • floor in areas adjacent to the plumes during times of low water level; c) speculate on the processes of formation of the precipitates, and; d) comment in their environmental significance.
