Stochastic Evaluation of Reservoir Operation Rules
The major water facilities in California encompass the State Water Project, operated by the State of California, and the Central Valley Project, owned and operated by the United States...
Probabilistic Dependable Hydro Capacity: Benefits of Synthetic Hydrology
This paper focuses on the benefits of using synthetic streamflows (the 'synthetic hydrology' approach) for determining a probabilistically defined dependable...
Seasonal Streamflow Forecasts Based Upon Regression
Many western water-supply system operators employ forecasts of seasonal inflows for the snow-melt season to plan spring and summer operations. This study considers the simple statistical...
City of Roseville, California, Alert System: Real Time Microcomputer Based Flood Warning System
The ALERT system was developed by the California-Nevada River Forecast Center of the National Weather Service. The System integrates self-reporting, field sensors, a base station microcomputer,...
The Los Vaqueros Model: A Microcomputer-Based Reservoir Planning System
This paper describes the development and application of a set of microcomputer models for the evaluation of a complex water resources project. The Los Vaqueros Model includes components...
Single-Channel Alluvial Fan Hydraulics with Application to Design of Medium-Density Projects
Methods to identify flood hazards on alluvial fans are provided by the Federal Emergency Management Agency (FEMA) in their Flood Insurance Study, Guidelines and Specifications for Study...
The Effects of Bank Protection on River Morphology
Revetment of bends with radius of curvature to width ratios (R/W) between 1.9 and 3.3 on Red River AR, and Sacramento River CA, does not cause the expected thalweg deepening and channel...
The Role of Vegetation in River Bank Erosion
The purpose of this paper is to describe briefly how streambank vegetation, both roots and shoots, modify the 'skin' or surface layer and how this in turn affects...
Numerical Model Studies of Wetland Hydraulics for Bolsa Bay, California
The Bolsa Bay area, near Los Angeles, presently consists of three distinct regions separated by two sets of culverts. A development is being considered, in which a balance between housing...
A Branched Hydrodynamic Model of the Sacramento-San Joaquin Delta, California
A new and efficient hydrodynamic model is used to simulate flows in the Sacramento-San Joaquin Delta, California. The model solves the one-dimensional shallow water equations for flow...
An Ongoing Investigation of Residual Suspended Material Transport in Central San Francisco Bay, CA
A study of suspended material transport in San Francisco Bay, California, is presently underway by the U.S. Army Corps of Engineers. This paper describes preliminary numerical model and...
Probability of Extreme Precipitation by Months
Daily rainfall records during the months of October through April at rainfall gaging stations near the Kings River drainage basin in the Sierra Nevada Mountains of central California were...
Hydrologic Implications of Global Warming on Water Resources in California
The possible effects of climate change on the water resources of the Sacramento-San Joaquin River Basin, as predicted by general circulation models (GCM's) were evaluated...
Conditional Simulation of the Wilmington Sand-Shale Sequence, Los Angeles Basin
In shaly clastic reservoirs at a scale where vertical cross flow cannot be ignored the main source of heterogeneity is the apparent random geometry of the sand-shale sequence. That geometry...
Sediment Ramping at Mill Creek
A Corps of Engineers study completed in 1988 analyzed this ramping phenomenon Mill Creek in Southern California Using an approach which combined sedimentation research with Corps experience...
Jet Injection Model Studies for the City of Los Angeles
The Hypersion Treatment Plant for the City of Los Angeles is currently undergoing an expansion project. A major component of this system is a sludge recycling system. And it is essential...
Design Procedures for Soil-Cement Grade-Control Structures
Grade-control structures are effective channel-stabilization measures that may be used singly or as a part of a stabilization plan involving such measures as bed and bank revetment. Grade-control...
Applicability of Several Common Methods of Debris Estimation
In southern California, the Tatum method and the Los Angeles County Flood Control District procedures have been widely used to estimation debris production rates. To evaluate the applicability...
Devil Canyon Second Afterbay
This project is located in the City of San Bernardino (Southern California). The addition of a second afterbay for the Devil Canyon Powerplant has been in the planning stages since October,...
Upgrading Trashraking Equipment During Scheduled Maintenance Outages
Four small hydro plants in Northern California were selected by Pacific Gas and Electric Company to upgrade and automate their trashrack raking equipment during the 1988 maintenance outages....
