Gravel dispersion on a granite pediment (East Mojave Desert, California): a short-term look at erosional processes
Autor: S. B. Edinger-Marshall, L. J. Lund
Publikováno v: Earth Surface Processes and Landforms. 24:349-359
Hypotheses about the influence of surface shape, landscape unit and vegetation cover on gravel dispersion were tested on a shallowly dissected portion of a low-sloping granite pediment in the East Mojave Desert of California. Painted gravels (2 to 20

Spatial and Temporal Variations in Nitrate Contamination of a Rural Aquifer, California
Autor: Z. J. Kabala, Alan E. Williams, J. A. Johnson, L. J. Lund
Publikováno v: Journal of Environmental Quality. 27:1147-1157
The quality of groundwater in the Sierra Pelona watershed, California is examined as an example of a small rural groundwater basin in a mountainous area of arid climate. Water quality in this region has been seriously impacted by nitrate (NO 3 ) cont

Natural and Anthropogenic Nitrate Contamination of Groundwater in a Rural Community, California
Autor: L. J. Lund, J. A. Johnson, Z. J. Kabala, Alan E. Williams
Publikováno v: Environmental Science & Technology. 32:32-39
Contamination of small basins impacts the quality of groundwater resources and the health of residents dependent on local, limited water supplies. Understanding contaminant sources is crucial not only to planning mitigation and cleanup but also to th

Factors Controlling Throughfall Characteristics at a High Elevation Sierra Nevada Site, California
Autor: L. J. Lund, Aaron D. Brown
Publikováno v: Journal of Environmental Quality. 23:844-850
The composition of throughfall (TF) is influenced by wet and dry deposition on foliar surfaces and by chemical and biological interactions between rain and the foliage. The relative importance of these process was investigated for TF collected in the

Mapping Soil Salinity Using Calibrated Electromagnetic Measurements
Autor: Dennis L. Corwin, James D. Rhoades, Scott M. Lesch, L. J. Lund
Publikováno v: Soil Science Society of America Journal. 56:540-548
A statistical modeling approach is presented that predicts spatial soil salinity patterns from aboveground electromagnetic induction (EM) readings. In this approach, EM readings are obtained from a field sampled on a uniform (centric systematic) grid

Block Diagrams and Soil Profile Characteristics in Soil Genesis and Classification Courses
Autor: S. B. Edinger, L. J. Lund
Publikováno v: Journal of Agronomic Education. 20:86-92
One objective of a soil morphology, genesis, and classification course is to teach students how to generate reasonable hypotheses to explain soil distributions on landscapes. By the end of the course, students can begin to make predictions regarding
