Sediment Transport Characteristics of Hyperconcentrated Flow with Suspended Load
In this paper, based on the analysis of the ovserved data, a set of theories is proposed of the transport of heper-concentrated sediment, the basic points of which are: (1) The hyperconcentrated...
A Mathematical Model of Erosion and Sedimentation of Hyperconcentrated Flow in Reservoirs
The motion of the flow with hyperconcentration has its unique law. In this paper, based on the analysis of the motion of the flow with hyperconcentration of sediment and the sediment transport...
A Study on Sediment Transportation in Debris Flow
By analysing the observation data of debris flows at the Jiangjia Ravine, Dongchuan, Yunnan Province, China in 1982-1986, this paper comprehensively and systematically describes the sediment...
Sediment Transport Models for Small Gullies in Loess Hill and Gully Regions
Three items are studied: the equation of the relation between discharge and sediment for small gullies derived by using the theory of river dynamics; the extension of the Nash theory of...
Sediment Sources, Transport and Delivery to an Alluvial Fan, Caliente Creek, California
Sediment delivery to a proposed flood detention reservoir site in the medial region of the Caliente Creek alluvial fan is dependant on the magnitude and duration of flood flows. Because...
Soil-Moisture Flux Studies on the Nevada Test Site A Review of Results and Techniques
Over the last 20 years, numerous studies of soil-moisture flux and/or ground-water recharge have been conducted on the U.S. Department of Energy's (DOE) Nevada Test Site (NTS)...
Erosion Processes in Upland Areas
After a soil particle is detached and entrained, it will be transported by the surface runoff. However, depending on the eroding and transport capacities of the surface runoff, some of...
Flood Control Improvements on Alluvial Fans
Floodplain management on alluvial fans has become an increasingly important issue with continued growth and urbanization in the southwest. The design of flood control facilities for new...
Task Committee on Transport Processes at the Interface of Water Column and Bottom Sediment
The Task Committee on Transport Processes at the Interface of Water Column and Bottom Sediment was formed on October 1, 1989 under the Technical Committee on Hydrologic Transport and Dispersion...
Observation of Sediment Resuspension in Old Tampa Bay, Florida
Equipment and methodology have been developed to monitor sediment resuspension at two sites in Old Tampa Bay. Velocities are measured with electromagnetic current meters and suspended...
A Review of the State-of-the-Art in Sediment-Water Column Interaction Measurement Techniques
This paper reviews the state-of-the-art measurement techniques available to water quality modeling practioners to estimate: (a) sediment oxygen demand rates, (b) sediment-water column...
Soluble Pollutant Enrichment in Snow Covers
A mathematical model is presented to simulate enrichment of soluble pollutants in snow covers. The model is based on the liquid water flow, heat transport, and pollutant transport equations....
A Branched Mass Transport Model of the Sacramento-San Joaquin Delta, California
A new branched mass (salt) transport model is used to simulate salt transport in the Sacramento-San Joaquin Delta, California. The model uses a two-step procedure to determine the salt...
A Computational Analysis of Dynamic Interaction of Dam with Reservoir Water and Sediment
A two-dimensional model of porous media is employed to calculate the reduction of the onset hydrodynamic pressure with the bulk modulus of pore water in reservoir sediment. However, the...
Effect of Temperature on Settling of Fine Sediments
Results from settling experiments in an annular flume using kaolinite clay in distilled water are presented. Identical experiments carried out at different temperatures show that as temperature...
A Hybrid Model for Sediment Concentration Profiles
The paper discusses the deficiency in the existing theories on suspended concentration profiles which is due to the variations of theories for modeling the velocity profiles. As can be...
Stable Channel Analytical Design Method
The Flood-Control Channels Research Program is being conducted at the US Army Engineer Waterways Experiment Station to develop systematic methods for design of stable channels for small...
Guidance on the Selection and Use of Sediment Discharge Formulas
The purpose of this paper is to discuss the sediment function module of the computer program SAM. SAM is being developed as a product of the US Army Corps of Engineers Flood Control Channels...
Physical Modelling of Self Forming Alluvial Channels
A method is presented for the determination of a practicable physical model of self-forming channels in cohesionless alluvium. Both sand bed and gravel bed regime channels are considered....
The Sediment Weighted Histogram Generator and Estimation of Sediment Transport Trends
Long term sediment transport trends may be evaluated using a sediment histogram generator program that was written for microcomputers. Flows can be extracted directly from a compact disc...
