By definition, integrated water resources management (IWRM) deals with planning, design and operation of complex systems in order to control the quantity, quality, temporal and spatial distribution of water with the main objective of meeting human and ecological needs and providing protection from water disasters. Complexity is a result of water resources system structure and interaction betwee...

In areas lacking substantial freshwater resources, the utilisation of alternative water sources, such as desalinated seawater and reclaimed water, is a sustainable alternative option. This paper presents an optimisation approach for the integrated management of water resources, including desalinated seawater, wastewater and reclaimed water, for insular water deficient areas. The proposed mixed ...

Design of policies within the integrated water resources management (IWRM) paradigm demands to take into account multiple objectives such as flood protection, water supply for hydropower generation, irrigation and urban use, imposition of minimum environmental flows, etc.. Finding efficient water management policies is a demanding task and Stochastic Dynamic Programming (SDP) can provide an eff...

Integrated Water Resources Management (IWRM) has often been interpreted and implemented in a way that is only really suited to countries with the most developed water infrastructures and management capacities. While sympathetic to many of the criticisms levelled at the IWRM concept and recognising the often disappointing levels of adoption, this paper and the series of papers it introduces iden...

An integrated water resources management model for Canada, CanadaWater, has been developed using the system dynamics simulation approach. The CanadaWater model takes into consideration dynamic interactions between quantitative characteristics of the available water resources and water use that are determined by the socio-economic development level, population and physiographic features of Canad...

Wetlands as water resources have a special place in the semi-arid plateau of Iran and boundary determination is necessary for their effective conservation and conflict resolution among stakeholders that are dependent on these resources. Determination of the wetland boundaries should be commensurate with environmental features affecting on it which normally extend beyond water extent. Ecological...

a general overview on the prospective of various oxidation and combined processes in the treatment of tannery industry effluent are reported. various oxidation and combined processes such as uv/h2o2/hypochlorites, fenton and electro-oxidation, photo-chemical, photo-catalytic, electro-catalytic oxidation, wet air oxidation, ozonation, biological followed by ozone/uv/ h2o2, coagulation or ele...

Urban rainwater reuse preserves water resources and promotes sustainable development in rapidly growing urban areas. The efficiency of a large number of urban water reuse systems, operating under different climate and demand conditions, is evaluated here on the base of a new risk analysis approach. Results obtained by probability analysis (PA) indicate that maximum efficiency in low demanding s...
