Objective: Mashhad metropolis as the second largest religioncity in the world and the second largest metropolis of Iran with an annual 3 million pilgrims have significant direct and indirect effects on the watershed leading to the city and surrounding over the past four decades. There is no collection system and sanitation disposal network in towns and villages within the Torghabeh River. Meth...
Recently, a manuscript was published with the objective to complete a multivariable and multisite calibration and validation for the Soil and Water Assessment Tool (SWAT) model on the Motueka River basin by Cao et al. (2006). Physically based distributed parameter models, such as SWAT, have become a preferred tool to predict watershed response not only at the watershed outlet, but also at inter...
Environmental decision support systems (EDSSs) are an emerging tool used to integrate the evaluation of highly complex and interrelated physicochemical, biological, hydrological, social, and economic aspects of environmental problems. An EDSS approach is developed to address hot-spot concerns for a water quality trading program intended to implement the total maximum daily load (TMDL) for phosp...
The interaction between human activities and watershed geology is accelerating long-term changes in the carbon cycle of rivers. We evaluated changes in bicarbonate alkalinity, a product of chemical weathering, and tested for long-term trends at 97 sites in the eastern United States draining over 260,000 km(2). We observed statistically significant increasing trends in alkalinity at 62 of the 97...
California’s primary hydrologic system, the San Francisco Estuary and its upstream watershed, is vulnerable to the regional hydrologic consequences of projected global climate change. Previous work has shown that a projected warming would result in a reduction of snowpack storage leading to higher winter and lower spring-summer streamflows and increased spring-summer salinities in the estuary. ...
the application of e-learning systems - as one of the solutions to the issue of anywhere and anytime learning – is increasingly spreading in the area of education. content management - one of the most important parts of any e-learning system- is in the concern of tutors and teachers through which they can obtain means and paths to achieve the goals of the course and learning objectives. e-learn...
The Khabour River, southernmost tributary to the Euphrates, is a case study in the complexity of managing riparian resources. The river is located entirely within Syria but the watershed includes portions of Turkey and Iraq. Indeed, on account of the steep southward precipitation gradient in the region, the spring-fed Khabour is recharged almost exclusively by precipitation that falls on Turkis...
Some riparian areas of the country are in danger of deterioration due to uncontrolled exploitation coupled with loose implementation of environmental protection policies and regulations. Muleta River, a major watershed in Bukidnon, Philippines, was assessed to determine the present condition of its riparian habitat. Abiotic and biotic conditions of the river were assessed. Other factors includi...
SAR images data are the result of a coherent imaging system that produces the speckle noise phenomenon. Image segmentation is the process of separating or grouping an image into different parts. The good performance of recognition algorithms depend on the quality of segmented image. An important problem in SAR image application is correct segmentation. In this paper, we consider the problem of ...
due to lack of knowledge management system in the organization of technical and vocational university of iran (tvuni) and losing good employees because of retirement and substitution causes huge amount of costs to replace the similar expertise. there is no any suitable system in the tvuni to store, to document, and to distribute knowledge. based on the university’s features such as it has diffe...
