Analyzing Drought with a Simplified Climate Model
A simplified climate model with combined atmospheric-hydrologic processes has been developed at the University of California Davis for the study of physical processes related to drought....

Infiltration Properties at Two Sites in the Konza Prairie
The spatial variability of soil hydraulic properties that govern infiltration were investigated at a pristine site and an agricultural site in the Konza Prairie Research Area of east-central...

Aquifer Transmissivity Computations Based on Data from Pump-and-Treat Facilities
Contamination from petroleum hydrocarbons spilled from USTs is a concern in urban areas that depend on shallow unconfined aquifers for their water supply. Studies on the transmissivity...

The Environmental Valuation Reference Inventory (EVRI) for Water Related Benefits Transfers
Managing our water resources requires knowledge not only of flows, water chemistry and aquatic life, but also of the various uses and economic values that humans place upon the water....

Scour in Erodible Rock II: Erosive Power at Bridge Piers
Scour depths around bridge piers founded on erodible rock can be determined by making use of the Erodibility Index Method. This method defmes an erosion threshold by relating the erosive...

The Effect of Climatic Change on Hydrologic Variables
There has been increasing concern about the threat of global warming affecting the earth's climate. This warming scenario, called the greenhouse effect, is believed to be...

New Block Copolymers for Membrane Materials
New fluorine containing polymer materials, which contain n-fluoro octylacrylate (pFOA) or n-fluorooctylmethylacrylate (pFOMA) repeating units, are being explored for use in thin film composite...

Identifying Potential Trophic Relationships and Bioaccumulation Pathways between Fish and Invertebrates
A large ocean monitoring database was used to quantify relationships between demersal fish, epibenthic macroinvertebrates (EMI) and benthic infauna that provide potential pathways for...

Characterization of Canal Operations under Ideal Anticipatory Control
A dimensionless formulation of a gate.stroking model is being used to study general characteristics of control measures that need to be applied upstream in single.pool canal systems to...

Alachlor Transport in Laboratory Soil Columns
Spraying of agricultural chemicals result in their travel downward through the unsaturated zone and adsorption to the surrounding soil. Infiltration from rainfall and irrigation solubilize...
