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...

The Pukhtun of Swat in Northern Pakistan refer to Islam to justify the local practice of polygamy and female subordination. However, a survey of Islamic law shows its intent is far more egalitarian than Pukhtun practice. Using a mixture of case studies and statistical evidence, this paper argues that in Swat husbands take second wives mainly in a spirit of revenge, reflecting the endemic hostil...

This study assessed the impact of potential climate change on the nutrient loads to surface and sub-surface waters from agricultural areas and was conducted using the Soil and Water Assessment Tool (SWAT) model. The study focused on a 3500 km2 catchment located in northern England, the Yorkshire Ouse. The SWAT model was calibrated and validated using sets of five years’ measurements of nitrate ...
