Arkansas Water Resources Center Technical Reports

Four experimental filter fields were constructed with built-in monitoring equipment in Nixa soils. These soils contain many chert fragments and a fragipan about 60 cm below the soil surface. The fragipan restricts downward movement of water and is the designlimitingfeature. The four filter fields were: 1. A "standard" filter field, 76 cm deep. The bottom of the trench was in the fragipan. 2. A "modified standard" filter field, 30 cm deep. The bottom of the trench was above the fragipan. 3. A "modified pressure" filter field, 40 cm deep. The bottom of the trench was above the fragipan. In addition, …

Modeling Erosion On Long Steep Slopes With Emphasis On The Rilling Process, Michael C. Hirschi, Billy J. Barfield, Ian D. Moore

KWRRI Research Reports

A model of soil erosion, known as KYERMO, is presented which emphasizes those processes which are important on steep slopes. Particular emphasis is placed on modeling rill development and geometry since this is the least understood process in erosion mechanics. The model requires an input rill pattern.

Rainfall inputs to the model require the use of breakpoint rainfall and kinetic energy. Surface storage is calculated based on random roughness data of Linden (1979). Infiltration is modeled by use of the two layer Green-Ampt-Mein-Larson model as proposed by Moore and Eigel (1981). Runoff is related to rainfall excess and surface storage …

Improved Methods And Guidelines For Modeling Stormwater Runoff From Surface Coal Mined Lands, Michael E. Meadows, George E. Blandford

KWRRI Research Reports

The investgations, developments and guidelines for several hydrologic modeling strategies are presented. Investigations were conducted to determine appropriate event curve numbers for surface mined disturbed watersheds; and performance of four synthetic unit hydrograph models (SCS curvilinear, SCS single triangle, Williams and TVA double triangle) on 38 USDA experimental watersheds in 14 physiographic provinces using in excess of 270 events. A second test using only the SCS curvilinear unit hydrograph on 11 small watersheds and 48 events was conducted to investigate the excess rainfall pattern simulated with the curve number model. A procedure for developing a unit hydrograph using the time …

Predicting Infiltration And Surface Runoff From Reconstructed Spoils And Soils, Larry G. Wells, Andrew D. Ward, Ronald E. Phillips

KWRRI Research Reports

A laboratory system was fabricated to measure infiltration and runoff from spoil and soil profiles constructed in rectangular bins. Construction, calibration and operation of a rainfall simulator is discussed and instrumentation used to measure transient infiltration and transmittance of water through experimental profiles is described.

Spoil and soil materials from surface mines in Eastern and Western Kentucky were transported to the laboratory and used in constructing experimental profiles in rectangular bins (0.91 x 1.83 x 1.07 m). An extensive series of infiltration experiments were conducted utilizing a rainfall simulator and soil moisture monitoring instrumentation. A dual probe gamma density gauge …

Disposal Of Household Wastewater In Soils Of High Stone Content (1977-1980), E. M. Rutledge, C. R. Mote, M. S. Hirsh, H. D. Scott, D. T. Mitchell

Arkansas Water Resources Center Technical Reports

Two experimental septic tank filter fields were constructed with built-in monitoring equipment in Nixa soils. These soils contain many chert fragments and a fragipan about 60 cm deep which restricts downward water movement and is the design-limiting feature. The standard filter field (76 cm deep) was built into the fragipan and the modified standard filter field (30 cm deep) was placed above it. During 30 months' observation, the modified standard performed better than the standard filter field. Maximum rise of effluent in the standard and modified standard came within 11 and 19 cm of the soil surface, respectively. Performance of …

Bibliography Of Nebraska Geology, 1843-1976, John H. Sandy, Jay Fussell

Conservation and Survey Division: Faculty and Staff Publications

Preface

The computer brightened the 1970s considerably by giving researchers a tool for storing, retrieving and manipulating electronically sizable blocks of literary material on a single subject. which would otherwise have cost researchers years of scholarly investigation to bring together. It was in such a propitious moment mat we set out to assemble this state bibliography as an aid to scholars, researchers. scientists, teachers, writers, editors, and decision makers in the earth sciences, universities, and all levels of government.

As we collected, compiled, and checked citations for this bibliography, we relied heavily on the following standard sources that have indexed …

Hydrological Studies In Soil Salinity, C J. Henschke

Resource management technical reports

Investigations involved examination of near-surface indurated layers to investigate their role in saltland formation. It was found that groundwater could move readily through this layer due to the presence of macro-pores. Close examination of apparently impermeable pallid zone clays, shows that decayed tree roots and large diameter voids provide a continuous pathway for the veritical transport of saline water from deeper aquifers.

An Assessment Of Wisalts Banks At Dangin, C J. Henschke, J A. Bessell-Browne

Resource management technical reports

This report compares two alternative approaches for the treatment and management of salt affected land at Dangin, Western Australia by determining whether there are benefits from a WISALTS bank system which would not accrue from standard soil conservation recommendations; comparing the costs and benefits of the two systems; and determining the nature of the effects of the two systems, particularly with respect to soil salinity.

Progress Report On Effects Of Contour Banking On Surface Runoff At The Berkshire Valley Experimental Catchment (Near Moora) 1961-82, K J. Bligh

Resource management technical reports

The time lag prior to peak runoff following rains of comparable high intensity increased by approximately 80 per cent in the largest event after the construction of contour banks. Although 80 per cent more runoff also occurred because the catchment was wetter and had been cultivated for three years in a row, the peak rate of runoff increased by only approximately 20 per cent. That the peak rate was not increased by 80 per cent, may be primarily attirbuted to the effect of the contour banks.

Atrazine Degradation, Sorption And Bioconcentration In Water Systems, Duane C. Wolf, Ramon L. Jackson

Arkansas Water Resources Center Technical Reports

The herbicide atrazine is used extensively to control broadleaf and grass weeds in such crops as sorghum and corn. A small portion of the atrazine may be lost from the area of application by surface runoff and could enter a stream or lake. The objective of this study was to evaluate atrazine degradation, sorption, and bioconcentration in watersediment systems. The results indicated that sediments with lower pH values and higher organic matter levels adsorbed higher levels of atrazine than sediments with neutral pH values and lower organic matter levels. Microbial decomposition of the herbicide was slow under the conditions of …

Preliminary Groundwater Investigations In Relation To Soil Salinity At Fitzgerald, Western Australia, C J. Henschke

Resource management technical reports

This study investigated soil salinity problems in relation to new land releases at Fitzgerald near the south coast of Western Australia. Fairly widely spaced set of bores was established to compare the groundwater hydrology regimes beneath cleared and virgin land. A large storage of soluble salts (over 100 kgm-2 in some profiles) was measured in the pallid zone clays under both cleared and virgin land conditions. Seasonal fresh to brackish perched watertables were found to overlie highly saline deep waterbles at a number of valley sites on land which has been cleared for agriculture during the past 15 years. Salinity …
