In this study, we apply an integrated land use and transportation model, the Sacramento MEPLAN model, to evaluate transit investment alternatives combined with supportive land use policies and pricing polices in the Sacramento region. Highway investment alternatives are simulated as well for purposes of comparison. The application of the Sacramento MEPLAN model is relatively advanced because th...

Pumping at the water export facilities in the southern Sacramento-San Joaquin Delta kills fish at and near the associated fish-salvage facilities. Correlative analyses of salvage counts with population indices have failed to provide quantitative estimates of the magnitude of this mortality. I estimated the proportional losses of Sacramento River Chinook salmon (Oncorhynchus tshawytscha) and del...

-The San Francisco Estuary is the largest estuary on the west coast of North America and one of the most altered . It supports a diverse fish fauna in which key species are in severe decline . The estuary is faced with catastrophic structural and ecological changes, especially in the Sacramento-San Joaquin Delta and Suisun Marsh, as the result of levee failure caused by the combination of earth...

I read with great interest the report by Bessac et al. entitled: “Transient receptor potential ankyrin 1 antagonists block the noxious effects of toxic industrial isocyanates and tear gases (1).” In the introduction the authors mention a variety of environmental exposure scenarios, including Bhopal, India, and a large-scale pesticide spill that occurred on the Sacramento River in Northern Calif...

A probabilistic risk assessment was conducted to evaluate the likelihood and ecological significance of potential toxic effects of diazinon in the Sacramento-San Joaquin system. Diazinon, an organophosphorus insecticide, is used in the Sacramento-San Joaquin River Basin as a dormant spray on almonds and other tree crops, as well as for other agricultural and urban applications. Diazinon and oth...

During California’s Gold Rush of 1849–1855, thousands miners rushed to San Francisco, Sacramento, and elsewhere throughout northern California, creating a significant demand for food. Here we in...
