The development of the Water Framework Directive aimed to establish an integrated framework of water management at European level. This framework revolves around inland surface waters, transitional waters, coastal waters and ground waters. In the process of achieving the environment and ecological objectives set from the Directive, the role of economics is put in the core of the water managemen...

Urban communities around the world are grappling with challenges associated population increases, drought, and projected water shortages. With a substantial global shortfall between supply demand expected by 2030, planning strategies must adapt to new reality characterized higher temperatures less precipitation, requiring ways of thinking about management, use, governance. Commonplace such as c...

Applied water quality monitoring of coastal zones or aquatic systems, such as rivers and lakes, requires processing of multiple images with variable temporal and spatial resolution. Compatible results in this case can be obtained by sensor-independent processing techniques. The physics-based, flexible, modular image processing system MIP can ensure standardized product outputs for a variety of ...

EDTA: THE CHELATING AGENT UNDER ENVIRONMENTAL SCRUTINY. The chelating agent EDTA (ethylenediaminetetraacetic acid) is a compound of massive use world wide with household and industrial applications, being one of the anthropogenic compounds with highest concentrations in inland European waters. In this review, the applications of EDTA and its behavior once it has been released into the environme...

Organisms can adapt to local environmental conditions as a plastic response or become adapted through natural selection on genetic variation. The ability to adapt to increased water temperatures will be of paramount importance for many fish species as the climate continues to warm and water resources become limited. Because increased water temperatures will reduce the dissolved oxygen available...

A freshwater lens underlain by saltwater exists beneath the entire northern Yucatan karst plain, Mexico. Water levels recorded in this plain, during the period June 1987 April, 1989, were used to map the water table, identify inland hydrogeologic boundaries, and estimate the thickness of the freshwater lens using the Ghyben-Herzberg relation. The water table under most of northwestern Yucatan i...

To develop the models for chlorophyll (CHL) estimation, the nature of a peak near 700 nm on the reflectance spectrum of water should be investigated. Simultaneous measurements of the reflectance spectra from 400 to 750 nm and relevant water quality constituent concentrations were carried out. A shift of the peak position and an increase of the peak magnitude, when chlorophyll concentration incr...
