  • Governance and socio-political issues in management of acid mine drainage in South Africa

    The water resources in South Africa are threatened by current and past mining practices such as abandoned and closed mines. While mining is considered valuable for its contribution to this country's gross domestic product, its polluting effects on water and land resources have been criticised as unsustainable. Acid mine drainage (AMD) is one specific public health and ecological issue that has ...

  • 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 ...

  • Adaptation to urbanization impacts on drainage in the city of Hohhot, China

    This study presents a quantitative assessment of urbanization effects on hydrological runoff and drainage network in the city of Hohhot, China. The evolution of urban spatial morphology for the historical years (1987–2010) and projected year (2020) is described by changes in geographic information system (GIS)-based land use maps and further represented in hydrological parameters in the Storm ...

  • PondR: a process-oriented model to simulate the hydrology of drainage ponds

    Drainage ponds are a useful measure to manage water resources. However, these small water bodies are characterized by highly dynamic internal processes. This article discusses a simple process-oriented model developed to simulate temporal dynamics of internal processes within drainage ponds. The PondR model is able to simulate the relevant hydrological processes of the pond by using commonly ...

  • Flood control in an urban drainage system using a linear controller

    Effective management of floods in densely populated urban areas poses a great challenge. Computer modeling plays an important role in appropriate management of urban drainage systems. In this study an effort has been made to develop an efficient urban drainage model in which hydraulic results obtained from the developed SWMM model have been linked with a Proportional Integral Derivative (PID) ...

  • GIS applications in urban drainage master planning - Case Study

    Introduction: The City of Stratford, Ontario, located 150 km (94 mi.) west of Toronto, initiated the development of an infrastructure asset database in the early 1990’s and continues to develop digital mapping to support the maintenance and management of municipal services. In continuing these efforts, the City initiated the City-Wide Storm System Master Plan (the Study) in 2002 to ...

  • Flood control and disaster management

    Flood control refers to all methods used to reduce or prevent the detrimental effects of flood waters (wikipedia). Some of the common techniques used for flood control are installation of rock berms, rock rip-raps, sandbags,  maintaining normal slopes with vegetation or application of soil cements on steeper slopes and construction or expansion of drainage channels. Other methods include ...

  • 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 ...

  • 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 ...

  • Flood forecasting within urban drainage systems using NARX neural network

    Urbanization activity and climate change increase the runoff volumes, and consequently the surcharge of the urban drainage systems (UDS). In addition, age and structural failures of these utilities limit their capacities, and thus generate hydraulic operation shortages, leading to flooding events. The large increase in floods within urban areas requires rapid actions from the UDS operators. ...

  • 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 ...
