Soil erosion is one of the most serious land degradation problems and the primary environmental issue in the Loess Plateau region of China. To identify the critical sub-basins and assess the impacts of land use change and climatic variability change on soil loss, this study tested the feasibility of the Soil and Water Assessment Tool (SWAT) model on sediment load simulation in the upper Sang-ka...

INTRODUCTION The Centers for Disease Control and Prevention developed the Swift Worksite Assessment and Translation (SWAT) evaluation method to identify promising practices in worksite health promotion programs. The new method complements research studies and evaluation studies of evidence-based practices that promote healthy weight in working adults. METHODS We used nationally recognized pro...

Watershed models such as SWAT (Soil and Water Assessment Tool) simulate water quality impacts of land and water resource management alternatives. To simulate these impacts, long-term daily rainfall data are necessary. In the absence of measured rainfall data, watershed models use weather generators to simulate rainfall events. The objective of this study is to examine several daily precipitatio...

Agricultural pollutant runoff is a major source of water contamination in California’s Sacramento River watershed where 8500 km of agricultural land influences water quality. The Soil and Water Assessment Tool (SWAT) hydrology, sediment, nitrate and pesticide transport components were assessed for the Sacramento River watershed. To represent flood conveyance in the area, the model was improved ...

With the increasing knowledge about the natural processes, hydrological models such as the Soil and Water Assessment Tool (SWAT) are becoming larger and more complex with increasing computation time. Additionally, other procedures such as model calibration, which may require thousands of model iterations, can increase running time and thus further reduce rapid modeling and analysis. Using the w...

III Lincoln Laboratory recently completed the three-year Short-Wavelength Adaptive Techniques (SWAT) field program, designed to investigate the performance of adaptive optics in a variety of scenarios. This article describes the operation of the SWAT adaptive optics system working with cooperative beacons. Examples are presented of system operation in compensating star images and in propagating...

The key to integrating a biological index to output from the SWAT/HUMUS model is to develop a relationship between the pertinent output from SWAT (nutrients and sediment) to the biological index. Wang et al. (2007) began developing the relationship between nutrients and assemblages of fish and macroinvertebrates in 240 wadeable streams in Wisconsin. From their sampling data they were able to de...

In this paper we introduce a new algorithm for assigning sensors and weapons to targets in the dynamic environment, where sensors, weapons, and targets are allowed to move freely (but predictably) over a certain region of a battlefield. In addition, we determine when such an assignment should be executed. This new algorithm for Sensors/Weapons And Targets pairings is named SWAT. In SWAT the opt...

Results of modelling studies for the evaluation of water quality impacts of agricultural conservation practices depend heavily on the numerical procedure used to represent the practices. Herein, a method for the representation of several agricultural conservation practices with the Soil and Water Assessment Tool (SWAT) is developed and evaluated. The representation procedure entails identifying...
