Rock Riprap for Grade Control
Rock chutes (riprap channels on steep slopes) are used as grade control structures to safely conduct a water flow to a lower elevation. Common procedures used for design of rock riprap...
Drop Structures in the Real World: Guidelines for Drop Structures in Grass Lined and Wetlands Channels
Dynamic Analysis of Multi-Pool Irrigation Canal
This paper discusses the dynamic characteristics of an open multi-pool irrigation canal from robustness point of view. In particular, the presence of right-half plane zeros in an open...
Estimate the Hazards of Bank Burst in the Lower Yellow River
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...
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...
Use of Channel Forming Discharge Concepts for Flood Control Channel Design
Evidence suggests that for perennial and ephemeral rivers that are in regime, bankfull flow is strongly correlated with channel morphology. Evidence suggests that this discharge is also...
Vegetative Roughness in Flood Control Channels
Laboratory flume tests and field evaluations were undertaken as a part of the Flood Control Channels Research Program to determine hydraulic roughness values for various types of floodplain...
Hydraulic Effects of Habitat Structures in Flood Control Channels
Three field sites have been established and laboratory flume experiments begun to assess the effect of habitat enhancement measures on water-surface profiles and local scour in flood control...
Debris Basin Design Procedures
Debris basins are widely used in the southwestern areas of the United States, with the majority of the structures located in the Southern California area. More and more development is...
Application of Regime Theory in Practice: A Case Study
Alluvial channels are known to adjust their slope, width, depth and velocity to achieve stable conditions given a supply of water and sediment. Scientific investigations of stable channels...
California Border Environment Activities Since Passage of NAFTA
This paper presents a summary of the activities undertaken by the State of California to improve the border environment since passage of the North American Free Trade Agreement (NAFTA)...
Reduction of Downstream Impacts Through Use of Variable Detention Basin Volume Requirements
The Pre-post Match is the standard policy for regulating the design of detention basins for new developments despite evidence showing that as multiple developments occur in a watershed,...
Channel Junction Effects in Channel Network Flow Simulation
In this paper, the momentum equations, which are applicable at channel junctions, are suggested based on the conservation of momentum flux. In the equation, the lateral inflow angles are...
Modeling Unsteady Open-Channel Flows Having Longitudinally Varied Fluid Density
Unsteady flows in waterways with fluid density varying longitudinally can be described by various sets of partial differential equations, according to conditions of density variation....
Impacts due to Density Current Deposition in Reservoirs
Different flow pafterns of density currents in reservoirs are discussed. In delta region, lateral density currents from non-stratified flow in the main channel occurs resulting in floodplain...
Simulation of Channel Changes Induced by a Reservoir
A fluvial study was made for potential stream channel changes induced by a reservoir. It is generally recognized that a reservoir induces sediment deposition along the upstream channel...
Mitigation of Flood Hazard on Alluvial Fans
A number of investigators have suggested that the limits of the traditional, stochastic, one-dimensional model of alluvial fan flooding have been reached and that there are one- and two-dimensional...
Design Alternatives for Protection of the Santa Ana River Interceptor Sewer
The Santa Ana River Interceptor Sewer (SARIS) line buried within the floodplain of the Santa Aria River is being threatened by long term degradation of the river bed at the pipeline crossings,...
