This study was conducted to determine if the Agricultural Policy/Environmental Extender (APEX) model could reasonably replicate the effects of silvicultural practices on streamflow and loading of sediments and nutrients. APEX was modified to enhance

The ∼190±5 Ma Big Creek hornblende-syenite and monzogabbro batholith has an outcrop area of ∼400 km2 within the Yukon–Tanana Terrane (YTT) in the west-central part of the Yukon Territory of Canada. Paleomagnetic analysis of 245 specimens from

The ~75 Ma Mount Lorne monzodiorite stock has been studied paleomagnetically to estimate the tectonic motion of the northern Canadian Cordillera since the Late Cretaceous. The stock is one of several paleomagnetic studies currently underway at the Un

This is the first of several Lithoprobe paleomagnetic studies underway to examine geotectonic motions in the northern Canadian Cordillera. Except for one controversial study, estimates for terranes underlying the Intermontane Belt in the Yukon have b

Effects of long-term prescribed burning on infiltration and interrill erosion were assessed on two longleaf pine-bluestem sites in Louisiana. Treatments represented biennially-applied winter, spring, or summer burning on an upland sandy loam site for

Technology for modeling runoff and erosion on rangelands has improved, but improvements in simulation accuracy are often lost in techniques used to estimate model parameters. This is particularly true on semiarid rangelands which have significant spa

Five small (4 ha) forested watersheds in East Texas were instrumented in December 1980 to determine the effect of forest harvesting, mechanical site preparation, and livestock grazing on stormflow, peak discharge rate, and sediment loss. After three

The 94 Ma La Posta granitoid pluton is intruded into the eastern zone of the Peninsular Ranges batholith in southern and Baja California. Paleomagnetic analyses of 297 specimens from 25 sites along an ∼45 km stretch of Interstate 1-8 across the plu

Simulated rainfall was used to study infiltration rates and sediment production of28 plant communities and soils of five watershed areas in central and eastern Nevada. Two antecedent moisture conditions were used: soil initially air dry and initially
