  • Comparative analysis of the outflow water quality of two sustainable linear drainage systems

    Three different drainage systems were built in a roadside car park located on the outskirts of Oviedo (Spain): two sustainable urban drainage systems (SUDS), a swale and a filter drain; and one conventional drainage system, a concrete ditch, which is representative of the most frequently used roadside drainage system in Spain. The concentrations of pollutants were analyzed in the outflow of all ...

  • What is so hard about drainage modeling?

    Drainage modeling often suffers from the misconception that it is simple, but while it appears obvious that rain water will flow to the lowest point, the physical processes involved are not always well-understood or predictable. Drainage models attempt to predict that part of the water cycle that involves rainfall and its consequences, including potential flooding. Although flooding is, at its ...

  • Predicting infiltration pollutant retention in bioretention sustainable drainage systems: model development and validation

    A major problem of increased urbanization is the rise in pollution caused by runoff. A solution to this problem can be found through the use of Sustainable Urban Drainage Systems (SUDS) such as rain gardens. Previous research has focused primarily on hydrologic design including the degree to which groundwater is replenished by these systems and models have been developed to quantify the extent ...

  • Catchment delineation and morphometric analysis using geographical information system

    The geographical information system (GIS) has emerged as an efficient tool in delineation of drainage patterns of watershed planning and management. The morphometric parameters of basins can address linear, areal and relief aspects. The study deals with the integrated watershed management of Baliya micro-watersheds, located in the Udaipur district of Rajasthan, India. Morphometric analysis in ...

  • Correlation analysis and threshold value research on the form and function indexes of an urban interconnected river system network

    As urbanization has accelerated, the form of river and lake systems has changed greatly in cities, which has caused variations in the functioning of the interconnected river system network (IRSN). To quantitatively evaluate the influence of the urbanization process on IRSN, the form index system and function index system were established in this study. The form index system involved eight ...

  • Sustainable wastewater separation treatment systems coupled with nutrient and water reducing greywater reuse technologies

    Nationally and internationally, pressure is increasing to introduce nutrient reducing, water conserving and recycling measures for sustainable residential and small community water/wastewater systems. Reports of inadequate water quality and quantity are being reported daily. Over the past thirty years the federal government and State of Alaska have invested over 4 billion dollars installing piped ...

  • Simulation of wastewater treatment plant within integrated urban wastewater models

    In the federal state of Hesse in Germany the application of an integrated software modelling framework is becoming part of the planning process to attain legal approval for the operation of combined sewer systems. The software allows for parallel simulation of flow and water quality routing in the sewer system and in receiving rivers. It combines existing pollution load model approaches with a ...

  • Identification of groundwater potential zone of Nawada district, Bihar (India) – a study based on remote sensing and GIS platform

    A study was conducted to delineate the groundwater potential zones of Nawada district of Southern Bihar using satellite-derived information layers, namely, elevation, slope, drainage density, land use, fractional impervious surface (FIS) and also using existing thematic maps (lithology, soil, pre- and post-monsoon water level) based on the weighted linear combination method. On the basis of the ...

  • Tengiz oil fields, Kazakhstan case study

    Client: Chevroil CSG supplied a half kilometre stretch of D400 Translinea to the Oil and Sulphur fields in Kazakhstan. The site, operated by Chevroil, is located on the shores of the Caspian Sea in North West Kazakhstan and covers some 970 square miles. It is the sixth largest oil field in the world holding an estimated 25 Billion barrels. When running at full capacity the area is capable of ...

  • Missing the Fairway – A Creative Sewer Design through a Private Golf Course

    THE PROBLEMThe City of Sioux Falls, South Dakota is experiencing rapid growth and is being pressured to open additional land for development. A ridgeline on the City’s eastern border prevents the extension of the existing gravity sewer system and creates the need for a completely new system. As shown in Figure 1, the new $31 million dollar system will extend from the ridgeline eastward to the Big ...

  • Developing optimum solutions to flooding

    Developing optimum solutions to flooding With a very long period of wet weather in the summer overlaid by intense rainfall, 2007 was the wettest summer in the UK on record. This unusual weather pattern resulted in very high localised runoff, with three events in England exceeding the 1 in 100 year return period over that time – some of the worst flooding that has ever occurred in ...

  • Erosion and Sediment Control: Navigating NPDES Regulations, the SWPPP, and Techniques for Compliance

    Erosion and Sedimentation: Why Are They a Problem? The US Environmental Protection Agency lists sediment as the single most common pollutant in rivers, streams, lakes, and reservoirs. With all the potentially harmful chemicals and substances in the world, it seems odd to many people that sediment—dirt, essentially—is singled out as the major culprit. Yet these particles of ...
