  • Vegetated ditches for treatment of surface water with highly fluctuating water regime

    Vegetated drainage ditches (VDD) as a type of constructed wetland primarily serve to remove and store excess water associated with irrigation and storm events. Current research suggests using a VDD as an additional practice in the mitigation of surface water pollution. The VDD for water treatment of the Glinscica River was constructed in 2006. The efficiency of the system was evaluated in 2008 ...

  • Automated Measurement of Slurry Surface Settlement

    An automated float method for measuring slurry surface settlement is described. The system consists of a Perspex float which is denser than water but lighter than the slurry into which it penetrates slightly and floats on the slurry/water interface. Settlement of this float is then automatically tracked using an LVDT. Comparison with direct cathetometer measurement demonstrates that except for ...

  • The hydrogeochemistry of the Lake Waco drainage basin, Texas

    The origin of surface water chemistry in highly impacted drainage basins must be investigated on a drainage-basin scale if the causes of the pollution are to be elucidated. This study characterizes and deciphers the surface water chemistry of a nutrient polluted river system in central Texas. Four tributaries of the Lake Waco reservoir were chemically characterized temporally and spatially in ...

  • Analytical solution for the flow velocity and water surface angle in drainage and sewer networks: case of pipes arranged in series

    Drainage and sewer network runs mostly under free surface flow condition. Among the characteristics which are important for practitioners are the flow velocity and water surface angle. The computation of these parameters in partially full pipes using Manning equation is implicit and requires iterative and laborious calculation methods. The goal of this paper is to provide a new method, where the ...

  • Acid mine drainage treatment

    Acid mine/rock drainage is a rampant problem in the world today. The above photo depicts acid drainage at an abandoned mine in the Yukon Territory of northwest Canada. This mine shares a similar history to thousands of other mines throughout the world. It was in operation for six short years in the 1950’s, producing gold ore. Its profitability eventually failed and it was abandoned. In the ...

  • The management of urban surface water flood risks: SUDS performance in flood reduction from extreme events

    The need to improve the urban drainage network to meet recent urban growth and the redevelopment of old industrial and commercial areas provides an opportunity for managing urban surface water infrastructure in a more sustainable way. The use of sustainable urban drainage systems (SUDS) can reduce urban surface water flooding as well as the pollution impact of urban discharges on receiving ...

  • A grid-based integrated surface–groundwater model (GISMOD)

    A distributed hydrological model, the Grid-based Integrated Surface-groundwater MODel (GISMOD), was developed to simulate hydrological processes by considering water interaction among different soil layers. The model integrates six modules. Basic information on catchment, such as the flow direction and the drainage network, can be obtained automatically from digital elevation model (DEM) data ...

  • Smart SUDS: recognising the multiple-benefit potential of sustainable surface water management systems

    How can we make sustainable urban drainage systems (SUDS) smart? SUDS help us to manage surface water runoff from urban environments but they are capable of delivering much more. This paper looks beyond the water quantity and quality improvement functions of SUDS and investigates the multiple benefits that can be gained by implementing smart SUDS solutions. This work provides a new perspective, ...

  • Characterization of the hydraulic performance of a gully under drainage conditions

    During rainfall events with low return periods (1–20 years) the drainage system can provide some degree of protection to urban areas. The system design is based not only on good hydraulic performance of the surface and the sewer network but also on their linking elements. Although the linking elements are of utmost importance as they allow the exchange of flow between the surface and the ...

  • Factors Influencing Mercury in Freshwater Surface Sediments of Northeastern North America

    We report on an inventory and analysis of sediment mercury (Hg) concentrations from 579 sites across northeastern North America. Sediment Hg concentrations ranged from the limit of detection ca. 0.01–3.7 g g–1 (dry weight, d.w.), and the average concentration was 0.19 g g–1 (d.w.) Sediment methylmercury concentrations ranged from 0.15 to 21 ng g–1 (d.w.) and the mean concentration was 3.83 ng g–1 ...

  • Methodologies to study the surface hydraulic behaviour of urban catchments during storm events

    A good knowledge of the hydraulic behaviour of an urban catchment and its surface drainage system is an essential requirement to guarantee traffic and pedestrian safety. In many cases, inlets have been situated according to spatial density criteria. Indeed a more rational location of inlets on urban catchments must be defined according to an accurate analysis of the relationship between street ...
