background: provision of safe drinking water is one of the basic needs of every society and it will only be possible through preventive and comprehensive management of drinking water security programs such as haccp. hazard analysis critical control point (haccp) is an internationally accepted process control system which includes recognition and determination of risk factor properties of proces...

The spatial and temporal variations of Ross River virus infections reported in Queensland, Australia, between 1985 and 1996 were studied by using the Geographic Information System. The notified cases of Ross River virus infection came from 489 localities between 1985 and 1988, 805 between 1989 and 1992, and 1,157 between 1993 and 1996 (chi2(df = 2) = 680.9; P < 0.001). There was a marked increa...

Introduction Recent debate has focused on the timing of events that initiated the Colorado River and first delivered sediments to fault-bounded basins in the Salton Trough. Any successful model for integration of this system must include regional linkages from the Colorado River source to the basinal depocenter in the Salton Trough. The Bouse Formation is a regionally extensive, latest Miocene ...

In recent years, new ideas and techniques appear very quickly, like sustainability, adaptive management, Geographic Information System, Remote Sensing and participations of new stakeholders, which contribute a lot to the development of decision support systems in river basin management. However, the role of models still needs to be emphasized, especially for model-based decision support systems...

The paper discusses how the well known USACE HEC models, RAS and HMS, are fully integrated within the decision support system of the Romagna River Basins in order to predict flood effects. The models are fully available from the web and cope with such a variety of problems as rainfall-runoff modeling, river and civil works hydraulics, and the mapping of hydraulic hazard. The paper illustrates t...

limitations on freshwater resources have caused water resources managers to focus an increasing attention over the past few decades on water quality protection. surface water quality management in such resources as rivers, seas, lakes, and estuaries is of a greater importance than other water resources and a greater number of studies have been conducted on them as they are more accessible and, ...

Models are essential in a decision support system for river basin management. In a decision support system for integrated planning and management, the use of appropriate models is important to avoid models being either too simple or too complex. In this paper, appropriate models refer to models that are good-enough-but-not-more-than-that to obtain an acceptable ranking of river engineering meas...

The title of my paper comes from an essay by Václav Havel. In his essay, Havel addressed most evocatively the question of the unique power of words for thinking and to influence, for good or for harm, as well as to inform and to educate. As analysts our medium is the word. I suggest that it is of inestimable importance that we are able to listen deeply to our patients' words and to be aware of ...

In this note we describe the notion of a rectifiable scan and consider some applications [DH1], [DH2] to Plateau-type minimization problems. “Scans” were first introduced in the work [HR1] of Tristan Rivière and the second author to adequately describe certain bubbling phenomena. There, the behavior of certain W 1,3 weakly convergent sequences of smooth maps from 4 dimensional domains into S le...

Conservation attention on charismatic large vertebrates such as dolphins is often supported by the suggestion that these species represent surrogates for wider biodiversity, or act as indicators of ecosystem health. However, their capacity to act as indicators of patterns or trends in regional biodiversity has rarely been tested. An extensive new dataset of >300 last-sighting records for the Ya...
