Simulation Of Daily And Monthly Stream Discharge From Small Watersheds Using The Swat Model, Crystal A. Spruill, Stephen R. Workman, Joseph L. Taraba

Biosystems and Agricultural Engineering Faculty Publications

The Soil and Water Assessment Tool (SWAT) was evaluated and parameter sensitivities were determined while modeling daily streamflows in a small central Kentucky watershed over a two-year period. Streamflow data from 1996 were used to calibrate the model and streamflow data from 1995 were used for evaluation. The model adequately predicted the trends in daily streamflow during this period although Nash-Sutcliffe R² values were –0.04 and 0.19 for 1995 and 1996, respectively. The model poorly predicted the timing of some peak flow values and recession rates during the last half of 1995. Excluding daily peak flow values from August …

Pride Water Quality Assessment Report: I. Problems And Programs, Kentucky Water Resources Research Institute. University Of Kentucky

KWRRI Research Reports

This report provides an overview of the water quality problems and associated state and federal programs in the 40 counties that make up the PRIDE region. The 2000 Kentucky 305(b) stream assessment has identified over 1000 miles of impaired stream within the region. The major cause of pollution in the region is related to problems with pathogens. Much of these problems are related to straight pipes and failing septic and wastewater systems. It has been estimated that there are over 35,000 straight pipes and failing septic systems in the PRIDE region. A second major environmental impact in the region is …

Pride Water Quality Assessment Report: Iii. Existing And Proposed Monitoring Network, Kentucky Water Resources Research Institute, University Of Kentucky

KWRRI Research Reports

This document provides a recommendation for proposed sampling sites in support of the general water quality assessment of the 40 county PRIDE region. A general assessment of the associated environmental problems and programs in the region can be found in the companion report: PRIDE Water Quality Assessment Report I: Problems and Programs while the report PRIDE Water Quality Assessment Report II: Chemical, Biological and Habitat Assessments provides a 10 year baseline assessment of environmental conditions in the region as measured by indicators of pH, fecal coliforms, habitat assessment, and macro-invertebrate assessment.

Pride Water Quality Assessment Report: Ii. Chemical, Biological And Habitat Assessments, Kentucky Water Resources Research Institute, University Of Kentucky

KWRRI Research Reports

The efficient utilization of federal funds in improving the water quality and aquatic habitat of the region requires a mechanism for assessing and evaluating the impacts of the proposed and ongoing projects as well as some mechanism for prioritizing the allocation of additional funds. In order to evaluate the effectiveness of these projects it is important to provide a formal monitoring and assessment program based on sound scientific principles. This report provides an initial 10 year baseline assessment of the existing water quality conditions in the 40 county PRIDE·region for the purpose of evaluating the impacts of the PRIDE programs …

Effects Of Longwall Mining On Hydrology, Leslie County, Kentucky Part 2: During-Mining Conditions, Shelley Minns Hutcheson, James A. Kipp, James S. Dinger, Lyle V.A. Sendlein, Daniel I. Carey, Gregory L. Secrist

Report of Investigations--KGS

The effects of longwall coal mining on hydrology in the Eastern Kentucky Coal Field are being investigated. The study area is in the Edd Fork watershed in southern Leslie County, over Shamrock Coal Company's Beech Fork Mine. Longwall panels approximately 700 ft wide are separated by three-entry gateways that are approximately 200 ft wide. The mine is operated in the Fire Clay (Hazard No. 4) coal; overburden thickness ranges from 300 to 800 ft. Mining began in panel 1 in September 1991 and concluded with panel 8 in September 1994. Long-term monitoring consisting of a network of piezometers and time-domain …

The Effect Of Turfgrass Maintenance On Surface-Water Quality In A Suburban Watershed, Inner Blue Grass, Kentucky, R. Michael Williams, James S. Dinger, Andrew J. Powell, Dwayne R. Edwards

Report of Investigations--KGS

Nutrients and pesticides applied during routine maintenance or establishment of turfgrass could result in nonpoint-source pollution. Nutrient and pesticide concentrations in water exiting a turfgrass management area in the Sinking Creek watershed, a suburban watershed in the Inner Blue Grass Region of central Kentucky, were monitored. This watershed was selected because it contains multiple land uses: agricultural, residential, and recreational (golf course).

A survey was conducted to determine the extent to which lawn-care products are used in the residential sector of the watershed. For the golf-course portion, the golf-course superintendent recorded chemical application daily.

Runoff from the golf course was …

1998-1999 Monitoring Strategy, Kentucky River Basin Management Unit, L. Ormsbee, G. Epp, E. Caudill, Lee Colten

KWRRI Research Reports

During the fall of 1997 and spring of 1998 about 40 individuals and more than 30 organizations and agencies provided input into the development of a monitoring strategy for the Kentucky River basin under the Kentucky Watershed Management Framework. In addition to the agencies that were able to commit resources to the monitoring effort, citizen input was sought in the design of the strategy. Citizen monitoring efforts are also providing valuable information in many portions of the state. The intent of the coordinated planning process was to carefully consider agency resources and capabilities, taking into account where and when each …
