The Soil and Water Assessment Tool (SWAT) was evaluated parameter sensitivities were determined whilemodeling daily streamflows in a small central Kentucky watershed over two-year period. Streamflow data from 1996were used to calibrate the model streamflow 1995 for evaluation. adequatelypredicted trends during this period although Nash-Sutcliffe R 2 values 0.04 0.19 for1995 1996, respectively. poorly predicted timing of some peak flow recession rates duringthe last half 1995. Excluding...

Policy scholars generally agree that greater coherence of policies is desirable, but the concept under‐theorized and has received little empirical examination. This research examines policy 18 domains considers institutional factors affect variation among them. There considerable in substantive, regional, identity‐based domains. Greater degrees exist for have dominant congressional committees or more involvement lead federal agencies. These findings extend what know about subsystems American...

In this article, we trace the evolution of punctuated equilibrium theories policy process to development a full theory government information processing. Noting that is one realization larger processing, outline research agenda for study setting, dynamics, and flows in process. doing so, relate processing such important features American as inter‐institutional dynamics delegation

The overall study objective was to evaluate the applicability of different qualitative and quantitative methods forcomparing daily monthly SWAT computer model hydrologic streamflow predictions observed data, recommendstatistical for use in future evaluations. Statistical were tested using streamflows monthlyequivalent runoff depths. statistical techniques included linear regression, Nash-Sutcliffe efficiency, nonparametrictests, t-test, functions, autocorrelation, cross-correlation. None...

Pasture runoff can contribute to elevated concentrations of nutrients, solids, and bacteria in downstreamwaters. The objective this study was determine the effects vegetative filter strip (VFS) length on concentrationsand transport nitrogen, phosphorus, solids fecal coliform from plots treated with cattle manure. Threeplots dimensions 2.4 30.5 m were used. upper 12.2 each plot manure, while thelower 18.3 acted as a VFS. Runoff produced by rainfall simulators sampled at VFS lengths 0, 6.1,...

Federal agencies are routinely confronted with requests from policymakers that they must address in some manner. These range routine directives to cut through red tape exceptional demands alter policy priorities. We theorize how attention is organized by public bureaucracies affects their responses. draw on a variety of scholarship about develop theory the bureaucratic organization and its consequences. In illustrating these notions, we trace federal agency threat terrorism as it gained...

We address theoretical and empirical aspects of policy disruptions that affect multiple areas policymaking. Our theorizing leads us to consider the effects widespread in gaining attention elected officials, affecting policymaking, reshaping involvement federal agencies. analyses concern threat terrorism United States its implications for public risk subsystems over past 25 years. policymakers resultant policymaking volatility show selective patterns subsystem disruption related terrorism....

The traditional means of tracking animal location in a field is by visual observation. Not only this method laborintensive, it also prone to error as the observer can alter cattle movement, observation periods are often too short obtainconfidence general daily behavior patterns, and fatigue becomes an issue. In 1990s, University Kentuckybegan using GPS collars on track their position with goal incorporating information into managementpractices. One key unanswered questions regarding accuracy...

Hydrologic modeling of karst watersheds requires detailed information on geologic settings and hydrologic properties for efficient simulation spring streamflow hydrographs. In this paper, sinkholes located in the streambed a watershed Kentucky were conceptualized as orifices, flow through these orifices was modeled function sinkhole diameter. The components incorporated soil water assessment tool (SWAT), called KarstSWAT study. able to reproduce observed hydrographs better than SWAT model...

The effects of cattle grazing on stream stability have been well documented for the western portion U.S.,but are lacking east. Stream and riparian damage resulting from can include alterations in watershedhydrology, changes to morphology, soil compaction erosion, destruction vegetation, water qualityimpairments. However, few studies examined successes best management practices (BMPs) mitigating theseeffects. objective this project was assess ability two common BMPs reduce streambank erosion...

ABSTRACT The transient, one-dimensional finite-difference model, SWATREN, was tested using field data from Aurora, North Carolina. SWATREN model could not be used for conditions when the water table rose to surface. Since frequently rises surface on poorly drained soils in humid regions of United States, modified by authors enable simulation these high tables. results were compared with performance management DRAINMOD, which had previously been same data. site consisted three drainage...

Preferential flow through large continuous pores affects the distribution of water in soil profile by reducing runoff and increasing total infiltration. In this study, a management model (PREFLO) was developed which could be used to simulate unsaturated saturated movement preferential might occur. PREFLO is based on one-dimensional finite difference solution Richards equation with nonuniform grid spacing. Large are described macroscopic scale vertical computed from for capillary tube. Water...

We consider the involvement of different interests in policymaking following disruptions that affect agendas multiple subsystems. The policy process literature suggests increased uncertainty and jurisdictional ambiguity could lead to substantial upheavals interest involvement. address these possibilities studying mobilization after terrorist attacks September 11, 2001, for eight disrupted Contrary expectations derived from literature, we find limited evidence upheaval or cross‐subsystem...
