2018 Nebraska Water Leaders Academy - Final Report, Mark E. Burbach Jan 1999

2018 Nebraska Water Leaders Academy - Final Report, Mark E. Burbach

Conservation and Survey Division: Faculty and Staff Publications

Nineteen participants completed the 2018 Water Leaders Academy bringing the total number of graduates to 120 since the inception of the program in 2011. Assessment of participants’ transformational leadership skills, champion of innovation skills, water knowledge and engagement, civic capacity, and entrepreneurial leadership behaviors showed a significant increase over the course of the year, from both participants’ and their raters’ perspectives. Feedback from participants was highly positive and constructive. Participant concerns were addressed, and only minor changes are planned for the 2019 Academy curriculum. Results of the program assessment indicate that the curriculum is meeting Academy objectives. Most importantly, Alumni …

Modelling Direct Episodic Recharge In The Western Australian Wheatbelt, F Lewis, Cooperative Research Centre For Catchment Hydrology (Australia) Nov 1998

Modelling Direct Episodic Recharge In The Western Australian Wheatbelt, F Lewis, Cooperative Research Centre For Catchment Hydrology (Australia)

Resource management technical reports

In agricultural regions of Western Australia, salinity is spreading. This is because the area taken up by groundwater discharge is increasing as a result of increased groundwater recharge following the replacement of native vegetation systems by annual crops and pasture species. Attempts to reduce groundwater recharge are now being made as it is hoped that this will decrease the rate of land salinisation. At several sites, average recharge rates have been estimated to be from 2% to 13% of the average annu ter hydrographs from the agricultural regions indicate that at some sites recharge does not occur as small amounts …


Managing Granite Outcrops. Revegetation On Farms Information Kit, David Bicknell, Department Of Conservation And Land Management (Calm), The Royal Society Of Western Australia Jul 1998

Managing Granite Outcrops. Revegetation On Farms Information Kit, David Bicknell, Department Of Conservation And Land Management (Calm), The Royal Society Of Western Australia

Natural resources published reports

In Western Australia, granite outcrops rise from the surrounding countryside like an extensive island chain, stretching from the high rainfall south-west to the arid interior. They are extremely rich in biodiversity, which can change dramatically from outcrop to outcrop. They may contain relics of unique plant and animal populations and are very significant for nature conservation.

Granite outcrops can also be a major source of groundwater recharge within catchments, especially where the surrounding fringe and woodland vegetation has been cleared.

What is granite?

*Granite is an igneous rock consisting of large crystals of quartz, feldspar and mica or hornblende.

An Atlas Of The Sand Hills, Ann S. Bleed, Charles A. Flowerday May 1998

An Atlas Of The Sand Hills, Ann S. Bleed, Charles A. Flowerday

Conservation and Survey Division: Faculty and Staff Publications

The Sand Hills region, approximately 19,300 square miles of sand dunes stretching 265 miles across Nebraska and into South Dakota, is the largest sand-dune area in the Western Hemisphere and is one of the largest grass-stabilized dune regions in the world.


The Physical And Hydrological Characteristics Of A South Coast Sandplain Site : East Howick Site Survey, Robert Anthony Sudmeyer Jan 1998

The Physical And Hydrological Characteristics Of A South Coast Sandplain Site : East Howick Site Survey, Robert Anthony Sudmeyer

Resource management technical reports

This Technical Report documents the physical and hydrological characteristics of a farmland site on the Esperance Sandplain. The site was located on 'Belalie Farm East' 110 km east of the town of Esperance in the locality of Howick (AMG 488900, 6277500) The site was typical of the sandplain landsystem which covers 35% (0.72 million ha) of the Esperance Agricultural Region. The farm was cleared over a number of years beginning in the 1970's and an extensive network of windbreaks established.


An Inventory And Condition Survey Of The Sandstone-Yalgoo-Paynes Find Area, Western Australia, A L. Payne, A M E Van Vreeswyk, K A. Leighton, H J. Pringle, P Hennig Jan 1998

An Inventory And Condition Survey Of The Sandstone-Yalgoo-Paynes Find Area, Western Australia, A L. Payne, A M E Van Vreeswyk, K A. Leighton, H J. Pringle, P Hennig

Technical Bulletins

The inventory and condition survey of the Sandstone-Yalgoo-Paynes Find area, undertaken by the Department of Agriculture and Food, Western Australia (DAFWA) between 1992 and 1993, 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 area’s natural 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 covers about …

Quartzite Fabric Transition In A Cordilleran Metamorphic Core Complex, Allen J. Mcgrew, Martin Casey Jan 1998

Quartzite Fabric Transition In A Cordilleran Metamorphic Core Complex, Allen J. Mcgrew, Martin Casey

Department of Earth, Environment and Sustainability Faculty Publications

Photomicrographs 143A-143F record fabric variations in quartzite with increasing structural depth in a > 1 km thick, amphibolite-facies, normal-sense shear zone in the East Humboldt metamorphic core complex, Nevada (Figure 143.1). This shear zone and the overlying detachment system unroofed an infrastructure of high-grade, migmatitic gneiss during Oligocene to early Miocene extension (Dallmeyer and others, 1986; Wright and Snoke, 1993; McGrew and Snee, 1994). Thermobarometric constraints from near the base of the mylonitic zone record deformation conditions of 550°- 620°C and 300-400 MPa (Hurlow and others, 1991). Sample WBC6 (l43A and 143B) characterizes the mylonitic zone, whereas sample 8706-1 (143C and …

Description Of The Sections And Subsections Of The Interior Highlands Of Arkansas And Oklahoma, Thomas L. Foti, George A. Bukenhofer

Journal of the Arkansas Academy of Science

Sections and subsections of the Interior Highlands of Arkansas and Oklahoma are redefined, mapped and briefly summarized. The map was produced to support the Ozark- Ouachita Highlands Assessment (OOHA), being conducted by the USDA Forest Service. It revises the USDA Forest Service map "Ecological units of the eastern United States, first approximation" by Keys et al. (1995) and the earlier maps of the natural divisions of Arkansas (Foti, 1974; Foti, 1976; Pell, 1983) to reflect new knowledge and to achieve consistency with units recognized in Missouri. Four sections (natural divisions) are defined as opposed to the three of the previous …
