Various researchers have concluded the existence of many glaciers in doubt by the end of this century due to global warming phenomenon. The great Himalayas are also under such stress. The recent acceleration in rainfall pattern resulted the ever worst destruction due to floods (2010) in Pakistan. Many Watershed models, capable of incorporating the climate change scenarios have been developed in...

A watershed is a complex ecosystem. Assessment of watershed condition entails consideration of numerous issues and factors. The problem is complex, the issues are not well defined, and data are often lacking. These characteristics suggest that a knowledgebased approximate reasoning approach is especially useful for watershed assessment. This paper describes a knowledge base for watershed assess...

Due to the rapid population growth and urbanization in the City of Calgary, the Elbow River watershed in southern Alberta covering 1238 km has been subjected to considerable land-use changes over the last decade. The objective of this study is to assess the impact of land-use intensification simulated with a cellular automata (CA) model on the hydrological processes of the watershed using MIKE-...

BACKGROUND AND PURPOSE Infarction in the internal border-zone region has been described radiologically and pathologically. The aim of this study was to define the clinical and pathophysiological correlates of internal watershed infarction. METHODS Eighteen consecutive stroke patients with evidence of internal watershed infarction on computed tomography (CT) were studied. RESULTS Two CT patt...

Evaluation of flow and transport processes in a watershed-scale requires that the watershed be divided into homogenous spatial units referred to as hydrologically similar units (HSUs). Although a few discretization schemes are already in use, a universally acceptable method of obtaining HSUs is yet to emerge. In this study, we developed a fuzzy inference system (FIS) to classify the saturated h...

Determining the sediment delivery rate and watershed delineation is among the first stage in environmental research, especially in water erosion estimation. The determining the accurate boundary of watershed is important for the hydrological and morphologic characteristics of watersheds. The study aims to present an automatic extraction model of watershed delineation and calculate sediment deli...

Sagitaria trifolia, Alisma plantago-aquatica and Echinochloa spp. are among the most important damaging weeds in paddy fields. In this research, Alternaria pellucida was isolated from the weeds and then its pathogenicity effects was examined on these weeds and five other rice cultivars, including two bred (Sepidroud and Khazar) and three landraces (Ali Kazemi, Hashemi and Binam), in a completel...

A mapping population consisting of 236 F2:3 families derived from the cross between two rice varieties, Gharib as female parent (with good cooking quality) and Sepidroud as male parent (with poor cooking quality) was used to analyze the quantitative trait loci (QTLs) associated with amylose content (AC), gelatinisation temperature (GT) and gel consistency (GC). A total of 105 single sequence re...

A watershed scale assessment of the effect of conservation practices on the environment is critical when recommending conservation management practices to agricultural producers. The identification of all sources of sediment and subsequent tracking of the movement of sediment downstream is a necessary part of this assessment including the often overlooked contributions from gully erosion source...
