An Inventory And Condition Survey Of Rangelands In The Ashburton River Catchment, Western Australia, A A. Mitchell, A L. Payne, W F. Holman

Technical Bulletins

The inventory and condition survey of rangelands in the Ashburton River catchment, undertaken by the Department of Agriculture and Food, Western Australia (DAFWA) between 1976 and 1978, describes and maps the natural resources of the region’s pastoral leasehold land. This survey report provides a baseline record of the existence and condition of the natural area’s resources, to assist with the planning and implementation of land management practices. The report identified and described the condition of soils, landforms, vegetation, habitat, ecosystems, and declared plants and animals. It also assessed the impact of pastoralism and made land management recommendations. The area surveyed …

Drought Management: The Role Of Near- Real Time Weather Data, Donald A. Wilhite, Kenneth G. Hubbard

National Drought Mitigation Center: Faculty Publications

The ability to collect weather data in near-real time has improved because of technological advances, enabling weather data users to obtain more weather data over wider areas, and in a more timely fashion. The number of near-real time climate networks is increasing as new applications are found for climate data. More than fifteen states in the United States have established automated weather station networks. This paper presents an overview of recent developments in automated weather data collection in the United States and gives a detailed description of the network in Nebraska.

Cropstatus--A Computer Program To Assess The Effects Of Seasonal Weather Changes On Nebraska's Agriculture, R. E. Neild, Donald A. Wilhite, K. G. Hubbard

National Drought Mitigation Center: Faculty Publications

CROPSTATUS is a series of programs residing in Nebraska's AGNET system using daily weather data to assess seasonal changes in crops, livestock, and other agricultural conditions. Assessments are based on parameters developed from accumulations of current daily temperature and precipitation data collected from a network of synoptic, climate, and automated micrometeorological stations in Nebraska in comparison with daily normals. The daily normals were derived from monthly summaries using multiple regression models to compute daily values as a function of Julian day numbers. Crop phenology models based on growing degree days were used to monitor and forecast the progress of different …

Improving Projected Potential Evapotranspiration Estimates Using National Weather Service Forecasts, Steven J. Meyer, Kenneth G. Hubbard, Donald A. Wilhite

National Drought Mitigation Center: Faculty Publications

In a recent survey conducted by the University of Nebraska's Center for Agricultural Meteorology and Climatology of Agricultural Network (AGNET) users, the results of potential evapotranspiration (ET_p) projections (calculated using the Blaney-Criddle approach, which employs "normal" climatic data to project ET_p estimates up to three days into the future) were labeled "unrealistic." To improve these projections, National Weather Service (NWS) forecast variables were used as input into the Blaney-Criddle and Penman equations. ET_p projections calculated according to the Penman equation, with data measured by automated weather stations as input, were assumed to represent the "best" …

Preliminary Groundwater And Salinity Investigations In The Eastern Wheatbelt 2. Merredin Catchment, Richard J. George Dr, P W C Frantom

Resource management technical reports

Saline groundwater occurs within twelve metres of the surface throughout the valley of the Merredin catchment. Saline groundwater occurs within deep sediments deposited in the valley and deeply-weathered bedrock materials. Rapid groundwater recharge appears to be taking place in sandy-textured soils high in the landscape and directly into the Cainozoic sediments in the valley floor. Water-tables are rising at approximately ten centimetres each year in the upper catchment area.

The Use Of Permeability, Conductivity, Conductance And Resistance In The Description Of Water Movement In Soils And Plants, H Borg

Resource management technical reports

Permeability, conductivity, conductance and resistance are important parameters in the description of water movement in soils and plants. These terms are related, but not synonymous. Permeability is only a function of the flow pathgeometry of the medium, while conductivity also depends on the fluid involved. Conductance, in addition, takes the size of the medium into account. Resistance is simply the inverse ofconductance. By applying the definition of resistance, it isshown that Darcy's law and Ohm's law are equivalent. Conductance and resistance relate volume flow rate to a potential difference, but to relate volume flux (volume flowrate per unit area) to …

Preliminary Groundwater And Salinity Investigations In The Eastern Wheatbelt. 3. Welbungin And Beacon River Catchments, Richard J. George Dr, P W C Frantom

Resource management technical reports

Water-tables show no obvious signs of a nett annual rise in the bores monitored in the valley floor, lower slope areas over the three year period. Groundwaters are extremely saline, the sedimentary and saprolite aquifers permeable (hydraulic conductivity range 0.1-2.0 m/day) (0.0001). Future management systems should seek to decrease recharge by changing rotations and farm practises while increasing discharge by using trees, pumps and halophytes. Options are available for drainage.

Development Of Dynamic Non-Hortonian Watershed Models For Steeply Sloping Forested Watersheds: Application To Eastern Kentucky, Lindell E. Ormsbee, Abdul Q. Khan

KWRRI Research Reports

A comprehensive conceptual watershed model is developed to simulate the hydrologic response of steeply sloping forested watersheds. Two non-Hortonian and two Hortonian models were first tested with data from selected watersheds in West Virginia and eastern Kentucky in order to understand the different mechanisms of flow responsible for storm hydrograph generation in this type of watersheds. The two non-Hortonian models tested were the kinematic storage model (Sloan et al. 1983) and the saturation deficit model (Beven and Wood, 1983). Both models were unable to adequately reproduce the observed hydrographs in the four forested watersheds considered in this research. The two …

A Preliminary Study Of The Hydrogeology Of The Dakota Formation In Douglas, Sarpy And Washington Counties, Eastern Nebraska, Thomas Mark O'Connor

School of Natural Resources: Dissertations, Theses, and Student Research

This study provides preliminary information on the hydrogeology of the Dakota Formation within a 1,000 square-mile area in eastern Nebraska. Isopach maps of the Dakota Formation and individual sand and gravel beds were constructed using a computer contouring program. Hydraulic conductivity values for water-bearing sand beds in the Dakota were estimated using the equation for calculating the specific capacity of wells and results from a grain-size analysis. Concentrations of major dissolved species were determined for samples collected from twenty five wells. The Dakota Formation is characterized by an increase in thickkness and an increase in percentage of clay versus sand …
