Ecological Modelling of River-Wetland Systems: A Case Study for the Abras de Mantequilla Wetland in Ecuador

Ecological Modelling of River-Wetland Systems: A Case Study for the Abras de Mantequilla Wetland in Ecuador

1st Edition

Forthcoming

Maria Gabriela Alvarez Mieles
July 16, 2019

Around 6% of the Earth's land surface is covered by wetlands. Wetlands play a key role in hydrological and biogeochemical cycles, delivering multiple benefits to society: sources of water supply, flood regulation, water purification, agriculture, fisheries, and biodiversity. Hence, wetland systems...

Improved Hydrological Understanding of a Semi-Arid Subtropical Transboundary Basin Using Multiple Techniques - The Incomati River Basin

Improved Hydrological Understanding of a Semi-Arid Subtropical Transboundary Basin Using Multiple Techniques - The Incomati River Basin

1st Edition

Forthcoming

Saraiva Okello
June 20, 2019

This study aims at improving the hydrological process understanding of the semi-arid and transboundary Incomati river basin to enable better water management. Comprehensive statistical and trend analysis of rainfall and streamflow were conducted, and the Indicators of Hydrological Alteration tool...

Estimating Combined Loads of Diffuse and Point-Source Pollutants Into the Borkena River, Ethiopia

Estimating Combined Loads of Diffuse and Point-Source Pollutants Into the Borkena River, Ethiopia

1st Edition

Eskinder Zinabu Belachew
May 09, 2019

This book is an initial attempt to estimate the loads of heavy metal and nutrient loads into an industrial effluent receiving rivers of a typical industrializing catchment. It shows the effects and impacts of diffuse and point sources of these loads into the rivers, and illuminate management,...

Integrating Multiple Sources of Information for Improving Hydrological Modelling: an Ensemble Approach

Integrating Multiple Sources of Information for Improving Hydrological Modelling: an Ensemble Approach

1st Edition

Isnaeni Murdi Hartanto
May 01, 2019

The availability of Earth observation and numerical weather prediction data for hydrological modelling and water management has increased significantly, creating a situation that today, for the same variable, estimates may be available from two or more sources of information. Yet, in hydrological...

Photo-Activated Sludge: A Novel Algal-Bacterial Biotreatment for Nitrogen Removal from Wastewater

Photo-Activated Sludge: A Novel Algal-Bacterial Biotreatment for Nitrogen Removal from Wastewater

1st Edition

Angélica Rada Ariza
April 25, 2019

Nitrogen rich wastewaters (10-400 mg N L-1) are usually produced by municipal, industrial and agricultural wastes, such as effluents from anaerobic treatments. These represent a risk to the environment due to the high nutrient concentrations (nitrogen and phosphorous), which can cause...

Protection of Public Health from Microbial and Chemical Hazards in Swimming Pool Environments

Protection of Public Health from Microbial and Chemical Hazards in Swimming Pool Environments

1st Edition

Yuli Ekowati
April 25, 2019

This thesis describes the occurrence of microbial and chemical contaminants in swimming pools and the investigation of an alternative disinfection technology, UVOX Redox® that could reduce reliance on chlorine and the formation of chlorinated disinfection byproducts (DBPs) in swimming pools. This...

Metal Recovery from Electronic Waste: Biological Versus Chemical Leaching for Recovery of Copper and Gold

Metal Recovery from Electronic Waste: Biological Versus Chemical Leaching for Recovery of Copper and Gold

1st Edition

Arda Işildar
November 15, 2018

Waste electrical and electronic equipment (WEEE) generation is a global problem. Despite the growing awareness and deterring legislation, most of the WEEE is disposed improperly, i.e. landfilled or otherwise shipped overseas, and treated in sub-standard conditions. Informal recycling of WEEE has...

Developing an Impact-Based Combined Drought Index for Monitoring Crop Yield Anomalies in the Upper Blue Nile Basin, Ethiopia

Developing an Impact-Based Combined Drought Index for Monitoring Crop Yield Anomalies in the Upper Blue Nile Basin, Ethiopia

1st Edition

Yared A. Bayissa
October 24, 2018

Having a robust drought monitoring system for Ethiopia is crucial to mitigate the adverse impacts of droughts. Yet, such monitoring system still lacks in Ethiopia, and in the Upper Blue Nile (UBN) basin in particular. Several drought indices exist to monitor drought, however, these indices are...

Novel Bioremediation Processes for Treatment of Seleniferous Soils and Sediment

Novel Bioremediation Processes for Treatment of Seleniferous Soils and Sediment

1st Edition

Shrutika Laxmikant Wadgaonkar
October 17, 2018

The aim of this Ph.D. was to develop a technology for the remediation of seleniferous soils/sediments and to explore microbial reduction of selenium oxyanions under different respiration conditions and bioreactor configurations. Seleniferous soil collected from the wheat-grown agricultural land in...

Optimization of the Electron Donor Supply to Sulphate Reducing Bioreactors Treating Inorganic Wastewater

Optimization of the Electron Donor Supply to Sulphate Reducing Bioreactors Treating Inorganic Wastewater

1st Edition

Luis Carlos Reyes-Alvarado
September 12, 2018

The main objective of this research was to optimize the electron donor supply in sulphate reducing bioreactors treating sulphate rich wastewater. Two types of electron donor were tested: lactate and slow release electron donors such as carbohydrate based polymers and lignocellulosic biowastes....

Sediments in the Tema Harbour (Ghana): Chemical Pollution and Sedimentation Rates

Sediments in the Tema Harbour (Ghana): Chemical Pollution and Sedimentation Rates

1st Edition

Benjamin O. Botwe
August 14, 2018

Sediment pollution and accumulation in harbours are major environmental issues and studies that advance their solutions are essential for harbour sustainability. This book provides the first comprehensive assessment of chemical pollution in sediments and sediment accumulation rates in the tropical...

Treatment of Petroleum Refinery Wastewater with Constructed Wetlands

Treatment of Petroleum Refinery Wastewater with Constructed Wetlands

1st Edition

Hassana Ibrahim Mustapha
August 14, 2018

Pollution of waterbodies and the environment by petroleum industry is of particular concern in Nigeria. This problem can be addressed by the application of constructed wetlands (CWs) which is a nature-based system that is simple to construct, have low operational and maintenance costs in terms of...
