This study explored the application of a multi-objective evolutionary algorithm (MOEA) and Pareto ordering in the multiple-objective automatic calibration of the Soil and Water Assessment Tool (SWAT). SWAT was calibrated in the Calapooia watershed, Oregon, USA, with two different pairs of objective functions in a cluster of 24 parallel computers. The non-dominated sorting genetic algorithm (NSG...

14 The Soil and Water Assessment Tool (SWAT) is a well established, distributed, eco15 hydrologic model. However, using the study case of an agricultural intensive irrigated 16 watershed, it was shown that all the model versions are not able to appropriately reproduce the 17 total streamflow in such system when the irrigation source is outside the watershed. The 18 objective of this study was t...

<p>Changes in land use are closely related to the increasing number of people who from time time. This change has an impact on runoff coefficient because rain that falls will not be retained or seep and flows directly into river. is what causes increase peak discharge a watershed. The purpose this study was determine magnitude changes occurred Serenan watershed 2015 2021 due use. method u...

Accurate predictions of sediment yield from distributed models of runoff and sediment yield depends in part of how well matched the model structure is to input data spatial representation. This study investigated how model structure and input data representation affect sediment predictions made using the Soil and Water Assessment Tool (SWAT). The study focused on the integration of two specific...

Microarrays are novel and dominant techniques that are being made use in the analysis of the expression level of DNA, with pharmacology, medical diagnosis, environmental engineering, and biological sciences being its current applications. Studies on microarray have shown that image processing techniques can considerably influence the precision of microarray data. A crucial issue identified in g...

This paper describes the effect of DEM data resolution on predictions from the SWAT model. Measured hydrologic, meteorological, watershed characteristics and water quality data from Moores Creek watershed (near Lincoln, AR, USA) were used in the simulation. The effect of input data resolution was evaluated by running seven scenarios at increasing DEM grid sizes (30 ð 30 m, 100 ð 100 m, 150 ð 15...

This paper discusses the development and application of a spatial tool for erosion modeling named Spatial Decision Assistance of Watershed Sedimentation (SDAS). SDAS computes export (yield) of sediment from watershed as product of erosion rate and sediment delivery ratio (SDR). The erosion rate is calculated for each raster grid according to a digital elevation model, soil, rain fall depth, and...

Abstract Purposely introduced in 1879, Pacific coast Striped Bass Morone saxatilis once supported a commercial fishery and currently supports recreational the San Francisco Estuary Watershed, CA, USA; however, population has been decline for decades. Since little is known about sub-adult behavior on coast, we used acoustic telemetry to investigate seasonal movement patterns habitat use across t...

Abstract The upper Benue River watershed is undergoing remarkable modifications due to man-made and natural phenomena. Hence, an evaluation required understand the hydrological process of for planning management strategies. This study aimed assess morphometric characteristics prioritize watershed. boundary sub-watersheds, as well stream networks, was extracted from digital elevation model (DEM)...

flood is one of the major natural disasters in iran, which is mostly, affected most parts of the country and caused hazards. therefore, identification of the area with high potential risk of flood occurrence is the main purpose in order to the flood control and reducing its damages. in this research the role of the flood routing in identification of the area with high potential flooding has inv...
