Land Reclamation In The North Stirling Land Conservation District, M F. Lewis, National Soil Conservation Program (Australia)

Resource management technical reports

Investigations were carried out to determine the interaction between the lakes and groundwater systems, the influence of bedrock structures on groundwater flow, and the regional flow characteristics in the basin. The hydrological investigations showed that water does flow from lakes to the groundwater system. However, the benefits from draining land have to be compared with the benefits of not adding water to the lakes. A basin water balance showed that most of the excess water resulting from reduced epotranspiration since clearing remains in the basin as increased groundwater storage. Only relatively small quantities of the extra water leave the basin …

Paleoenvironmental Analysis Of Three Subfossil Coleopteran Faunas From The Toklat River Drainage, Central Alaska, Lisa L. Churchill

Senior Scholar Papers

Three sediment samples were collected from exposures along the Tok lat River. Central Alaska and analyzed for subfossil Coleopteran remains. Two samples arc Holocene in age (650 ± b.p .. and submodem) and the other is believed to be laic Pleistocene in age, based on stratigraphic interpretations. The Pleistocene fauna was representative of a tundra environment adjacent to a fluvial system. The older Holocene sample was indicative of a point bar deposit wi rh sl ightly moister conditions. although rhe occurrence of several tundra species was also noted. These tundra species were evidently able to make the transition from their …

Mesh-Generating Computer Program For The Feswms-2dh Surface-Water Flow Model, Kirk G. Thibodeaux

United States Geological Survey: Staff Publications

A mesh-generating computer program, GNMESH, has been developed to generate two-dimensional finite element meshes for the U.S. Federal Highway Administration's FESWMS-2DH, a two-dimensional depth averaged finite element flow model. GNMESH uses a modified mapping technique that incorporates piecewise Hermitian and weighted interpolation schemes to layout the generated mesh within given or calculated flow tubes. Minimum required input data for GNMESH is required when the program is run using its default settings. These input data consists of the X, Y, and Z coordinates of points defining a minimum of three cross sections, the roughness coefficients at the given cross sections, an …

Rainfall-Runoff Relations For The Puget Sound Area, R. S. Dinicola

United States Geological Survey: Staff Publications

The characteristics of rainfall-runoff relations were hypothesized for the study area using existing information. These hypotheses were incorporated into the Hydrologic Simulation Program-FORTRAN, and the model was calibrated concurrently at 21 stream-gage sites in the study area. The simulation errors after model calibration were not large enough to reject the hypothesized characteristics. A proxy-basin validation effort was performed.

Characteristics Of U.S. Geological Survey Discharge Measurements For Water Year 1990, Janice M. Fulford

United States Geological Survey: Staff Publications

The U.S. Geological Survey (USGS) Water Resources Division makes ten of thousands of stream discharge measurements each year throughout the United States and Puerto Rico. The majority of the measurements requires the use of point velocity instrumentation. Interest in new instrumentation technology and the performance of in-use instrumentation prompted a survey of current-meter usage and discharge measurement data for water year 1990. This paper is a summary of survey results: the velocity, discharge and depth ranges measured; the types of meters used; and the measurement problems encountered.

Watershed Models For Resources Management Decisions, Alan M. Lumb

United States Geological Survey: Staff Publications

Comprehensive hydrologic analyses can be very effective for the assessment of hydrologic effects of land use and climate changes, but the costs and expertise is often prohibitive. Progress has been made in four areas to reduce the costs and expertise required: (1) Watershed Data Management (WDM) system for the storage and retrieval of data used and generated by the model, (2) an expert system for the calibration of the model, (3) use of Geographical Information Systems to generate distributed parameters for the model, and (4) easy to use software for applications of the model.

The basins studied are the Colorado River above Cisco, Utah: the Kissimmee River above Lake Okeechobee, Florida; the Mississippi River above Anoka, Minnesota; the Neuse River above Streets Ferry Bridge near Vanceboro, North Carolina; the Potomac River above Point of Rocks. Maryland; the Sacramento River above Sacramento, California: …

First- And Second-Order Patterns Of Stress In The Lithosphere: The World Stress Map Project, Mary Lou Zoback

United States Geological Survey: Staff Publications

To date, more than 7300 in situ stress orientations have been compiled as part of the World Stress Map project. Of these, over 4400 are considered reliable tectonic stress indicators, recording horizontal stress orientations to within < ±25 °. Remarkably good correlation is observed between stress orientations deduced from in situ stress measurements and geologic observations made in the upper 1-2 km, well bore breakouts extending to 4-5 km depth and earthquake focal mechanisms to depths of-20 km. Regionally uniform stress orientations and relative magnitudes permit definition of broad-scale regional stress patterns often extending 20-200 times the approximately 20-25 km thickness of the upper brittle lithosphere. The "first-order" midplate stress fields are believed to be largely the result of compressional forces applied at plate boundaries, primarily ridge push and continental collision. The orientation of the intraplate stress field is thus largely controlled by the geometry of the plate boundaries. There is no evidence of large lateral stress gradients (as evidenced by lateral variations in stress regime) which would be expected across large plates if simple resistive or driving basal drag tractions (parallel or antiparallel to absolute motion) controlled the intraplate stress field. Intraplate areas of active extension are generally associated with regions of high topography: western U.S. Cordillera, high Andes, Tibetan plateau, western Indian Ocean plateau. Buoyancy stresses related to crustal thickening and/or lithospheric thinning in these regions dominate the intraplate compressional stress field due to plate-driving forces. These buoyancy forces are just one of several categories of "second-order" stresses, or local perturbations, that can be identified once the first-order stress patterns are recognized. These second-order stress fields can often be associated with specific geologic or tectonic features, for example, lithospheric flexure, lateral strength contrasts, as well as the lateral density contrasts which give rise to buoyancy forces. These second-order stress patterns typically have wavelengths ranging from 5 to 10+ times the thickness of the brittle upper lithosphere. A two-dimensional analysis of the amount of rotation of regional horizontal stress orientations due to a superimposed local stress constrains the ratio of the magnitude of the horizontal regional stress differences to the local uniaxial stress. For a detectable rotation of 15 °, the local horizontal uniaxial stress must be at least twice the magnitude of the regional horizontal stress differences. Examples of local rotations of S_Hmax orientations include a 750-85 ° rotation on the
northeastern Canadian continental shelf possibly related to margin-normal extension derived from sediment-loading flexural stresses, a 50 °-60 ° rotation within the East African rift relative to western Africa due to extensional buoyancy forces caused by lithospheric thinning, and an approximately 90 ° rotation along the northern margin of the Paleozoic Amazonas rift in central Brazil. …

Deep Drains : A Case Study And Discussion, Russell John Speed, John Andrew Simons

Resource management technical reports

Typically, deep, open drains are about 2 in deep and about 1 in wide at the base and dug with a backhoe or excavator. The movement of groundwater is controlled by two factors. One is the physical ability of the material to transmit fluid. Permeability is the measure used to describe the ability of a material to transmit fluid through pores and cracks. It depends largely upon porosity (the percentage of the total volume of thematerial that is pore space) and the degree of interconnectedness of the pore spaces. The other factor controlling groundwater flow is gradient. George (1985) found …

A Reconnaissance Study Of Herbicides And Their Metabolites In Surface Water Of The Midwestern United States Using Immunoassay And Gas Chromatography/Mass Spectrometry, E. Michael Thurman, Donald A. Goolsby, Michael Meyer, Margaret Mills, Michael L. Pomes, Dana W. Kolpin

United States Geological Survey: Staff Publications

Preemergent herbicides and their metabolites, particularly atrazine, deethylatrazine, and metolachlor, persisted from 1989 to 1990 in the majority of rivers and streams in the midwestern United States. In spring, after the application of herbicides, the concentrations of atrazine, alachlor, and simazine were frequently 3-10 times greater than the U.S. Environmental Protection Agency maximum contaminant level (MCL). The concentration of herbicides exceeded the MCLs both singly and in combination. Two major degradation products of atrazine (deisopropylatrazine and deethylatrazine) also were found in many of the streams. The order of persistence of the herbicides and their metabolites in surface water was atrazine …

Dissociation Quotients Of Malonic Acid In Aqueous Sodium Chloride Media To 100°C1, Richard Kettler, David J. Wesolowski, Donald A. Palmer

Department of Earth and Atmospheric Sciences: Faculty Publications

The first and second molal dissociation quotients of malonic acid were measured potentiometrically in a concentration cell fitted with hydrogen electrodes. The hydrogen ion molality of malonic acidJbimalonate solutions was measured relative to a standard aqueous HCI solution from 0 to 100°C over 25° intervals at five ionic strengths ranging from 0.1 to 5.0 molal (NaCl). The molal dissociation quotients and available literature data were treated in the all anionic form by a seven-term equation. This treatment yielded the following thermodynamic quantities for the first acid dissociation equilibrium at 25°C: log K_1a = -2.852 ± 0.003. ΔH_1̊a = …

Biogeography Of Campanian-Maastrichtian Calcareous Plankton In The Region Of The Southern Ocean: Paleogeographic And Paleoclimatic Implications, Brian T. Huber, David K. Watkins

Department of Earth and Atmospheric Sciences: Faculty Publications

Analysis of biogeographic distribution patterns among Campanian-Maastrichtian calcareous nannoplankton and planktonic foraminifera from the southern high latitudes provides insight to changes in circum-Antarctic climate and surface circulation surface routes. Both microfossil groups are similarly characterized in the early Campanian by low-diversity, cosmopolitan species with few or no austral provincial taxa. This changes by late Campanian-early Maastrichtian time as austral species diversified and began to dominate the high-latitude assemblages. Maximum diversity of austral provincial taxa occurs during the late Campanian among the planktonic foraminifera and in the early Maastrichtian among the calcareous nannoplankton. Climatic cooling is considered the cause for the …

Results Of Stubble Research In Western Australia, Michael Perry, Ron Jarvis, Mel Mason, David Tennant

Journal of the Department of Agriculture, Western Australia, Series 4

Few farmers would question the desirability of retaining stubbles, both for control of erosion by wind and water, and to return organic matter to the soil. While the present debate is focused on the short term management of stubbles, longer term effects also need to be considered.

The Department of Agriculture has several long-running trials intended to measure long term effects.

Current Research On Soil Nitrate Testing For Corn In Kentucky, John H. Grove

Soil Science News and Views

Concern has been expressed that growers do not have the "slte-specific" information they need for more efficient nitrogen (N) fertilizer management on a field-by-field basis. Soil testing has routinely been used to guide recommendations for phosphorus, potassium, and lime additions to individual fields, but effective soil N test procedures have long eluded soil scientists working in warm, humid regions with substantial winter rainfall. Now, recent research suggests that a new soil test procedure has some potential to guide fertilizer N applications for corn. The purpose of this report is to define the concept of soil nitrate testing; to describe how …
