Watershed nutrient management is essential in minimizing the eutrophication rate of reservoirs. A shortcoming in nutrient management of watershed-reservoir systems has been the lack of successful linking of watershed and water body models to evaluate impact of watershed management options on reservoir water quality. The objectives of this research were to 1) calibrate and validate a Soil and Wa...

In this paper, we investigate the links between the flooding paradigm and the topological watershed. Guided by the analysis of a classical flooding algorithm, we introduce several notions that help us to understand the watershed: minima extension, extension map, and pass values. We investigate the possibility for a flooding to produce a topological watershed, and conclude that this is not feasi...

As originally conceived, watershed analysis is a synthesis of information that focuses on issues important to a particular watershed in the context of larger eco-scape scales. Some practitioners of watershed analysis have ascended a steep and unfamiliar learning curve of synthesizing between disciplines and agencies and addressing ecosystem issues at a large scale. Yet, after two years of inter...

Onderstepoort Journal of Veterinary Research, 64:243-244 Over a period of 15 years, the larval stages of Diphyllobothri id tapeworms of the genus Spirometra were found during routine necropsy in four of 3 007 non-human primates at the Institute of Primate Research (IPR) .

The rare genus Blacometeorus Tobias, 1976 (Hymenoptera: Braconidae: Blacinae)is discovered in Yunnan, China, and a new species, Blacometeorus sinicus Chai & Chen, sp. n. is described and illustrated. It represents the first record of this genus both for China and Oriental region. A key to genus Blacometeorus is updated.

This paper introduces the object counting using the mark controlled watershed transforms. Watershed transform is usually adopted for image segmentation in the area of image processing and image analysis because it always generates closed contours for each region in the original image. This method is good choice for image segmentation in the field of mathematical morphology. In this paper we are...

The Chehel Kaman Formation of the upper Paleocene age formed from carbonate and siliciclastic sediments is located, in the Kapeh Dagh Sedimentary Basin. Two sections where considered for the purpose of research into the effective diagenetic processes of this formation. The Cheshmeh Qorban section with a thickness of 270.8m located 140km down the Mashhad – Sarakhs Highway while the Shourlog Sect...

One of the most important hydrological time series task is to determine if there is any trend in the data and how to achieve stationarity when there is nonstationarity behavior in data. Detecting trend and stationarity in hydrological time series may help us to understand the possible links between hydrological processes and global climate changes. In this study yearly, monthly and daily stream...

Public participation in environmental management is increasingly common across many natural resource sectors. Environmental policies in the water resources sector, in particular, depend upon both computer-based watershed modeling activities and public participation in watershed management decisions, though the integration of participation in watershed modeling remains uncommon. Case studies of ...
