Nowadays, there are too many models in the world for simulation of hydrological processes, such as the SWAT physically based model. The SWAT model is a continuous and physically based hydrologic model that is the smallest unit in this model is Hydrologic Response Unit, and all hydrological processes are simulated in each of these units. This model can simulate runoff, sedimentation, erosion and...
arid and semi-arid ecosystems are very sensitivity to changes. fluctuations in climate variables and increasing human activities; result in the changes in hydrological processes of these ecosystems, and consequently, their structures degradation. in this study, hydro-climatic data of the bakhtegan basin for the period of 1972–2011, were analyzed to assess effects of climate variability and huma...
BACKGROUND Few nomograms can predict overall survival (OS) after curative resection of advanced gastric cancer (AGC), and these nomograms were developed using data from only a few large centers over a long time period. The aim of this study was to develop and externally validate an elaborative nomogram that predicts 5-year OS after curative resection for serosa-negative, locally AGC using a lar...
the present paper investigates how far ideologies can be tease out in discourse by examining the employed schemata by two ideologically opposed news media, the bbc and press tv, to report syria crisis during a period of nine months in 2011. by assuming that news is not a valuefree construction of facts and drawing on micro structural approach of schema theory, for the first time in discours...
The scope of this paper is to describe, evaluate, and forecast fishing trip choices of the Bay of Biscay pelagic fleet using random utility modeling (RUM). First, alternative fishing trip choices of this fleet were identified using multivariate statistical methods based on species landings weighted by value and defined as distinct fishing activity or fisheries (termed métiers). A RUM was specif...
Regular operation of weather radar mandates frequent calibration to ensure accurate measurements. Even modest calibration errors in reflectivity factor Z and differential reflectivity ZDR may produce severe deficiencies in the quality of radar products such as rainfall estimates and hydrometeor classes. Radar users, including the Federal Aviation Administration (FAA), rely on high quality weath...
the wepp physically model is able to dynamically simulate runoff and soil erosion using physical concepts of erosion and hydraulic of overland flow science considering plant growth, residue decomposition, winter process. determination of the capability of this model in runoff and erosion estimation in different range type with investigation the effects of management were the main objectives of ...
The runoff simulation have particular importance in Civil works, river training, design and planning of ground water resources, flood control and prevention of environmental hazards and reduction of erosion and sedimentation in the watershed. The runoff in each region varies according to climatic conditions, hydrological, soil and vegetation in the basin. Simulate these processes need to ...
Permafrost is warming globally which leads to widespread permafrost thaw. Particularly ice-rich vulnerable rapid thaw and erosion, impacting whole landscapes ecosystems. Retrogressive slumps (RTS) are abrupt disturbances that expand by several meters each year lead an increased soil organic carbon release. Local Remote Sensing studies identified increasing RTS activity in the last two decades n...
