Environmental water governance in federal rivers: opportunities and limits for subsidiarity in Australia's Murray–Darling River
A reform process is underway in the Murray–Darling Basin (Australia) to reallocate water from irrigated agriculture to the environment. The scale, complexity and politics of the recovery process have prompted interest in the role of local environmental water managers within state and federal governance arrangements. This paper examines prospects for a local role in environmental water ...

An environmental perspective on the water management policies of the Upper Delaware River Basin
Since 1954, the Delaware River has been managed under the framework of a Supreme Court decree and the subsequent concomitant intergovernmental collaboration between New York State, New Jersey, Pennsylvania, Delaware, New York City (NYC) and the US federal government. Taking an environmental perspective, we review the evolution of water release policies for three NYC reservoirs from the ...

How to reallocate water rights when environmental goals conflict with existing entitlements
Emerging concerns for environmental flows translate into reforms that aim to preserve minimal flows in rivers. These policy measures have consequences for traditional right-holders: how to share between consumptive users the new scarcity created by the protection of instream flows? This paper compares different policy mechanisms in France, Australia and California in an attempt to answer the ...

Integrated constructed wetlands: water management as a land-use issue, implementing the ‘Ecosystem Approach’
Awareness of the need for social, economic and environmental coherence in the management of water is becoming evermore apparent. Water supply as well as treatment is becoming more costly; a challenge that is not only limited to developing countries. The use of wetlands, natural and constructed, is now more widely accepted as a means of tackling a range of problems in water management to deliver ...

Review of toxicological effects caused by episodic stressor exposure
Water quality monitoring tools that rely on data from stress‐response tests with continuous exposure at constant concentrations are not always appropriately protective when stressor exposure in the field is episodic in nature. The present study identifies various approaches that have attempted to account for episodic stressor exposure, describes the development of a toxicological effects database ...

Legislating for sustainable basin management: the story of Australia's Water Act (2007)
Australia's Millennium drought, a 13-year dry period unprecedented in the instrumental record, inspired a change in the extant water management principles. The Water Act of 2007 was introduced and required the preparation of a Basin Plan to set environmentally sustainable levels of water extraction and to reduce the over-allocation of water entitlements that threatened water security. ...

Application of water quality indices to define surface water quality in Tehran
Tehran is one of the capitals of the world that is not situated around a river, therefore surface water discharges into a network of natural streams and even some artificial canals. Owing to the lack of sewerage system, part of the sewage runs to the network of streams without any control. The aim of this work is to identify a baseline for the water quality, which will then help policy-makers and ...

The potential for reusing treated municipal wastewater for irrigation in the Hashemite Kingdom of Jordan
This paper elaborates on the chemical composition of wastewater at selected Wastewater Treatment Plants (WWTPs) in Jordan. These plants have immense potential of providing reused treated water for irrigation. Samples from treated effluents analysed to study the efficiency of the impact of treated water on irrigation. The results revealed the effluents from WWTPs could be used for irrigation with ...

Application of SWOT analysis for the management of transboundary River Evros (Bulgaria, Greece, Turkey)
River Evros is a transboundary river flowing through Bulgaria, Greece and Turkey and coincides with the borderline among them for a considerable part of its length in the downstream part of its basin. River Evros is historically engaged to a long series of serious and devastating flood events with high socio–economical costs and environmental impacts on the riparian communities and even on ...

Analysis of effects of climate change on runoff in an urban drainage system: a case study from Seoul, Korea
Both water quantity and quality are impacted by climate change. In addition, rapid urbanization has also brought an immeasurable loss of life and property resulting from floods. Hence, there is a need to predict changes in rainfall events to effectively design stormwater infrastructure to protect urban areas from disaster. This study develops a framework for predicting future short duration ...

Urban stormwater inundation simulation based on SWMM and diffusive overland-flow model
With rapid urbanization, inundation-induced property losses have become more and more severe. Urban inundation modeling is an effective way to reduce these losses. This paper introduces a simplified urban stormwater inundation simulation model based on the United States Environmental Protection Agency Storm Water Management Model (SWMM) and a geographic information system (GIS)-based ...

An evaluation of hydrologic modeling performance of EPA SWMM for bioretention
Recent techniques should be investigated in detail to avoid present and future problems of urbanization like flood, drought and water pollution. Low Impact Development (LID) Best Management Practices (BMPs) such as bioretentions, green roofs, rain barrels, vegetative swales, and permeable pavements have been implemented to diminish the adverse effects of urbanization. In this study, a ...

Effect of non-point source runoff and urban sewage on Yaque del Norte River in Dominican Republic
A Yaque del Norte, Dominican Republic watershed survey monitored dissolved oxygen, eutrophication from point and non-point sources, and high conductivity resulting from agricultural runoff. The upper mainly forested watershed had good water quality except for untreated sewage from the city of Jarabacoa. The mid-watershed had a deforested landscape, mixed agriculture and the city of Santiago ...

A model for integrated water resources management in water-scarce regions: irrigation with wastewater combined with desalination processes
We have developed a model for planning water supply from diverse sources, including groundwater, the National Water Carrier, wastewater and seawater. The model integrates hydrological, technological and economic considerations, and estimates the economic and environmental impacts of alternative water management policies; it was implemented in a case study of the Emek Heffer and northern Sharon ...

Monitoring, environmental emergencies management and water treatment improvement of freshwater lakes in China: the Chao Lake case study
Severe eutrophication of freshwater lakes, with the subsequent risk of algal blooms, has a critical effect on the safety of drinking water supplies in China and is one of the main environmental emergencies in the country. This paper focuses on Chao Lake, a large, shallow eutrophic lake used as a source of drinking water. The study considers the possibilities of improving the lake monitoring ...

What is Geomembrane used for in Civil Engineering?
Geomembranes are synthetic materials used extensively in civil engineering for various applications related to containment, environmental protection, and water management. They are typically made of polymers like high-density polyethylene (HDPE), low-density polyethylene (LDPE), polyvinyl chloride (PVC), and other flexible materials. Geomembranes serve several critical functions in civil ...
