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 …

Investigation Of Optimum Sample Number And Timing For Determining Pollution Loads, T. S. Soerens, Marc A. Nelson
Technical Reports
In order to determine the impacts of non point source (NPS) pollution and to develop Total Maximum Daily Loads (Tr\tfDLs), accurate measurements of pollution loads in streams are critical. The objectives of this study were to accurately detemline pollutant loads at two sites by intensive storm sampling, to develop sub-sampling and other data analysis techniques, to detemline the effect of sample interval on load calculation accuracy, and to find the minimum sample interval required to determine storm loads at a required accuracy. The two stream sites used were a 1st order and a 3rd order stream in the Illinois River …
A Conceptual Hydrogeological Model For The Lake Warden Recovery Catchments Esperance, Western Australia, R Short
Resource management technical reports
The National Land and Water Resource Audit (NLWRA), has identified Dryland Salinity as one of seven major themes for an audit of the nation’s land, water, vegetation and natural resource management. Within this theme, Project 3 has been developed to investigate a key catchment type and how management scenarios will impact on dryland salinity processes. The Lake Warden catchments have been chosen as one of four catchment water balance studies to be undertaken nationally. The catchment water balance analysis will be undertaken using numerical modelling by the CSIRO, Division of Land and Water.

Managing For Enhancement Of Riparian And Wetland Areas Of The Western United States: An Annotated Bibliography, David A. Koehler, Allan E. Thomas
United States Bureau of Land Management: Staff Publications
This annotated bibliography contains 1,905 citations from professional journals, symposia, workshops, proceedings, technical reports, and other sources. The intent of this compilation was to: (1) assemble, to the extent possible, all available and accessible publications relating to riparian management within a single source or document; (2) provide managers, field biologists, researchers, and others, a point of access for locating scientific literature relevant to their specific interest; and (3) provide, under one cover, a comprehensive collection of annotated publications that could disseminate basic information relative to the status of our knowledge.

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 …
