Potential Application to Studies of Pesticide Transport to California Ground Water. The purpose of this memo is to briefly summarize (i) methods for distinguishing different source contributions to shallow ground water using stable isotope markers, and (ii) methods for age-dating shallow ground waters using various environmental tracers. I. INTRODUCTION The Pesticide Contamination Prevention Ac...
One way cities are looking to promote bicycling is by providing publicly or privately operated bike-share services, which enable individuals rent bicycles for one-way trips. Although many studies have examined the use of little known about how these services influence individual-level travel behavior more generally. In this study, we examine users and non-users a dockless, electric-assisted ser...

The WSR-57 radar a t Sacramento provides an opportunity to observe mountain effects on precipitation and on radar echo patterns. Radar patterns representing a wide range of weather situations are described and interpreted in light of concurrent gage precipitation measurements. The frequent underestimation by radar of rainfall on windward slopes is attributed to the small drop size and low forma...
2 Geomorphologist and Hydraulic Engineer, respectively, Water Engineering & Technology, Inc., Fort Collins, Colorado. Abstract: A 160km-long reach of Sacramento River was studied with the objective of predicting future changes in channel planform and their effects on water-surface elevations. Planform data were used to develop regression relationships between bend radius of curvature (Rc) and b...
Changes in the position of the low salinity zone, a habitat suitability index, turbidity, and water temperature modeled from four 100-year scenarios of climate change were evaluated for possible effects on delta smeltHypomesus transpacificus, which is endemic to the Sacramento–San Joaquin Delta. The persistence of delta smelt in much of its current habitat into the next century appears uncertai...
