The discharge of wastewater from net washing is one of the most significant problems in the marine ecosystem because of its high organic and saline content. Sea water quality is deteriorated every day due to the high amount of organic matter produced in the aquaculture sector. The aim of this study...

Electrochemical Machiningplayed a vital role in the aircraft, atomic, and healthcare industries via electrochemical machining (ECM). Even with difficult-to-machine materials. ECM has generally preferred to machine Nickel-based alloys compared to other non-conventional and conventional machining...

Water resources are subjected to different pollution sources. Point source water pollution of surface water is an important issue when considering the limited surface water availability as well as the potential knock-on effects of this pollution on human health as well as habitat and land...

Athens in antiquity as well today, included all the settlements in the wider Attica region. That is why its official name was “the Athens” (plural). Since prehistoric times, the city of Athens and the wider region of Attica did not contain many natural water sources so aquatic reserves were never...

GROWA is a modular grid based empirical hydrological model that is being used to address practical water resources management related issues. It has been successfully applied in typical hydrological and hydrogeological setups of northern European basins ranging typically between meso-scale river...

Extreme floods often demonstrate unanticipated characteristics that pose problems for management and response. The flood in the Stratoni region in February 2010 provided an example of such unexpected response. The aim of this paper is the quantification of the hydrologic response of the torrents...

Determining peak flows for ungaged areas is difficult and involves high uncertainty. Advanced computer capabilities provided by geographical information systems and hydrologic modeling software are used for detailed determination of the parameters involved, both for simple methods as the rational...

In order to design a network of drainage canals, it is essential to consider the excess water from the agricultural land (overland flow) and to evaluate the characteristics of flow routing, such as the flow depths and discharges in the system of tertiary and main drainage canals of various order. In...

The present paper aims at a treatment technique designed for special industrial wastewaters contaminated with only traces of halogenated organic compounds (HOCs) – concentrations which are nevertheless large enough to make a discharge into municipal sewage works impossible. Our research follows the...

The intrusion of salt wedge in rivers is a natural phenomenon, which occurs in many estuaries. Saline water tends to propagate upstream from the river mouth, due to the limited freshwater and the tidal and density currents developed, resulting in deterioration of water quality in the lower river...

All stormwater management projects in Greece are required to get environmental permit before construction. The design return period is often determined by the environmental permit. Determination of design discharges is an important parameter for the design. Design discharge for a given return period...
