Drought Management in Northeastern Colorado
The Northern Colorado Water District (the District) has established a set of policies and procedures and constructed a water storage and distribution system that allows for the effective...
Results of Field Evaluations of the New Modular Inclined Fish Diversion Screen
The Electric Power Research Institute (EPRI) has developed and biologically evaluated a new type of fish diversion screen known as the Modular Inclined Screen (MIS). The MIS is designed...
Chandler Canal Fish Screen Facilities
Diversions from rivers must be protected from negative effects on migratory and non-migratory fish species. Diversions to canals often have to be screened to prevent removal and loss of...
How Did a California Dam Get a Section 404 Permit?
This paper describes the wetland mitigation planning and implementation efforts conducted for the Contra Costa Water Districts (CCWDs) Los Vaqueros Project in eastern Contra Costa County,...
Sediment Transport Modeling for the Glen-Colusa Irrigation District Fish Screen Modifications
The Glen-Colusa Irrigation District (GCID) pumping plant is located on an oxbow of the Sacramento River approximately 100 miles north of Sacramento (Figure 1). The existing fish screen...
Estimation of Bed Material Transport Capacity
A procedure is presented which combines several computational components for the estimation of bed material transport capacity in alluvial channels. Bed load transport is estimated through...
Upper Chehalis River Pollutant Capacity and Load Allocations
Dry season water quality was evaluated in the Upper Chehalis River in western Washington state, focusing on low dissolved oxygen (DO), and using the Total Maximum Daily Load (TMDL) process....
Challenges and Opportunities in Egypt's Integrated Water Resources Strategy
Egypt's Nile irrigation system is a very complicated, old operated, continuously expanding system. It may be also described as a highly productive irrigated agriculture system....
Juvenile Fish Separator Design
Separation by size of downstream migrant juvenile salmonids at hydroelectric projects in the Columbia River basin is an integral part of transportation and bypass programs. However, separation...
White River Fish Screen Project Planning and Design
In 1983, Puget Sound Power and Light Company (Puget Power) submitted a license application to FERC for the overall White River Project. One of the elements of the project application was...
Flooding from Rain-on-Snow Events in the Sierra Nevada
The most damaging floods in rivers of the Sierra Nevada of California have occurred during warm storms when rain fell in snow covered catchments. These large floods in the major tributaries...
Scour Study for Bridge Design on Temecula Creek
Channel-bed scour was studiedfor the proposed new Pala Road Bridge on Temecula Creek in Riverside County, California. In order to determine the general scour, sediment transport and potential...
Periodic Variation in Karst Stream Losses
A cave taking water from an ephemeral stream periodically reroutes surface and subsurface drainage because of a plug that forms 10 m below the main entrance to the cave. The plug of sand,...
Estimation of the Probable Maximum Rainfall and Snowmelt Floods Via Physically Based Model of River Runoff Generation
Disastrous floods can be caused by unusual combinations of hydrometeorological factors and river basin conditions that have not been observed during a long observation period. The physically-based...
Accidental Situations: Application of Surface-Water Monitoring Data
Under severe manmade environmental changes, nature-protective activities serve to effectively solve a triune task: conservation and recovery of environmental ecosystems, safety of man...
System of River Floods Warning in Ukraine
The diversity of climatic, geomorphologic, and soil conditions causes significant space differences in the conditions of river flood formation in Ukraine. The Carpathians region is the...
Application of GIS Technology to Floodplain & Habitat Analyses
A long-term flood control and maintenance plan for the Mojave River, located in southern California, is currently being developed to satisfy permit requirements for state and federal regulatory...
Water Resources Investigation Along Salt River in Phoenix and Tempe Area
The Salt River originates in the White Mountains of eastern Arizona and drains westward through the Phoenix metropolitan area to its confluence with the Gila River approximately 15 miles...
Suspended Sediment Loads in Dry and Wet Years
Many factors other than water discharge influence the suspended sediment load in rivers. The climate condition is one of the factors. It is expected that the relation between Qs...
Specification of Cu, Pb and Cr in Contaminated Sediment Effected by pH
Sediment was sampled from a contaminated river. Sequential extraction was applied to determine the speciations of Cu, Pb, and Cr in the sediment with varied pH (5?9), and the redox potential...
