  • A Dutch first in the polder - Water Board Zuiderzeeland measures flow rates to achieve sustainability

    The Dutch province of Flevoland lies metres below sea-level. That’s why rain and seepage need to be removed from the polder, some 6 metres up. And that’s the reason Flevoland is drained continuously by seven huge pumping stations. The quantity of energy involved in this is as great as the energy consumption of 4,000 households. Water Board Zuiderzeeland has launched the ‘Energy ...

  • 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 ...

  • Lake Edku water-quality monitoring, analysis and management model for optimising drainage water treatment using a genetic algorithm

    Lake Edku, one of the northern Nile Delta Lakes, subjected to huge inputs of nutrients (especially phosphorous and nitrogen). These nutritional conditions create rich resource spectrum for algal growth and make the lake suffer from high level of eutrophication. Lake Edku does not have numeric water quality criteria for nutrients. The main objective of this research is to develop a model which can ...

  • Integrated treatment of acid mine drainage using cryptocrystalline magnesite and barium chloride

    This study endeavours to report the efficiency of a hybrid approach in the treatment of acid mine drainage. Cryptocrystalline magnesite was used to pre-treat acid mine drainage and barium chloride was used to remove the residual sulphate through the formation of barium sulphate. Batch experimental approach was adopted and the documented optimum conditions for both cryptocrystalline magnesite ...

  • Optimization of hydrometric monitoring network in urban drainage systems using information theory

    Regular and continuous monitoring of urban runoff in both quality and quantity aspects is of great importance for controlling and managing surface runoff. Due to the considerable costs of establishing new gauges, optimization of the monitoring network is essential. This research proposes an approach for site selection of new discharge stations in urban areas, based on entropy theory in ...

  • Evolution of an integrated 1D/2D modeling package for urban drainage - Case Study

    Introduction: Recent flooding events in North America have revealed deficiencies in existing stormwater infrastructure and management practices. The development of effective and efficient designs requires a comprehensive understanding of flooding in urban areas and complex open channel and overland flow systems. Traditional one dimensional (1D) models are used to simulate flow in river ...

  • Two-stage combined treatment of acid mine drainage and municipal wastewater

    This study examined the feasibility of the combined treatment of field-collected acid mine drainages (AMD, pH = 4.2 ± 0.9, iron = 112 ± 118 mg/L, sulfate = 1,846 ± 594 mg/L) and municipal wastewater (MWW, avg. chemical oxygen demand (COD) = 234–333 mg/L) using a two-stage process. The process consisted of batch mixing of the two wastes to ...

  • Past, present, and future design of urban drainage systems with focus on Danish experiences

    Climate change will influence the water cycle substantially, and extreme precipitation will become more frequent in many regions in the years to come. How should this fact be incorporated into design of urban drainage systems, if at all? And how important is climate change compared to other changes over time? Based on an analysis of the underlying key drivers of changes that are expected to ...

  • Assessing the potential of using telecommunication microwave links in urban drainage modelling

    The ability to predict the runoff response of an urban catchment to rainfall is crucial for managing drainage systems effectively and controlling discharges from urban areas. In this paper we assess the potential of commercial microwave links (MWL) to capture the spatio-temporal rainfall dynamics and thus improve urban rainfall-runoff modelling. Specifically, we perform numerical experiments ...

  • Fate of hydrocarbon pollutants in source and non-source control sustainable drainage systems

    Sustainable drainage (SuDs) is an established method for managing runoff from developments, and source control is part of accepted design philosophy. However, there are limited studies into the contribution source control makes to pollutant removal, especially for roads. This study examines organic pollutants, total petroleum hydrocarbons (TPH) and polycyclic aromatic hydrocarbons (PAHs), in ...
