Geomorphology and Sedimentology of a Valley Fan, Southern Utah
Sink Valley, located in semi-arid west-central Kane County, Utah, lies on an erosional surface of Cretaceous age Tropic Shale. The valley contains an example of a previously undocumented...
Experimental Investigation of Density-Driven Hyperconcentrated Flows
Lock-exchange type of laboratory experiments have been conducted in order to evaluate the dynamical characteristics of density-driven hyperconcentrated fluid mud. Fluid mud, confined in...
Activation and Degeneration of Turbidity Currents
Flow properties of the front of a turbidity current are investigated using the two layers model which takes into account of pick up and deposition of sediment. The amount of pick up rate...
Resistance Consisting of Both Viscous Force and Dispersive Force
A set of specially designed experiments have been carried for studying the resistance of a flow consisting of water and both fine and coarse particles. The viscous force caused by fine...
Limit Concentration of Suspended Sediment
It is found from experiments that there is a limit on suspended sediment concentration. The limit concentration of uniform sediment varies with sediment diameter, and it is about 1000...
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...
Arid Zone Hydrologic Implications for the Proposed Yucca Mountain Repository
The U.S. Department of Energy (DOE) has chosen Yucca Mountain, Nevada for characterization to determine if it is suitable to become the Nation's first High-Level Radioactive...
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...
Prediction of Debris Flow Prone Areas and Damage
It is very important when drawing hazard maps to estimate damage to houses from debris flow of certain fixed quantities. A debris flow disaster, which occurred in Kake Town, Hiroshima...
Stochastic Modeling of Monthly Flows in Streams of Arid Regions
A new stochastic model is presented herein which is applicable to simulating monthly flows of streams in arid regions. The model enables one to reproduce the percentage of zero flows in...
Way Against Debris Flows at China's Mountain Towns
For important protected objectives, the measures against debris flow in mountain towns should ensure all-round reliability and adopt a comprehensive system of engineering projects combined...
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...
Flow Distribution in Multiple Channels with Partial Ice Coverage
It is not uncommon for rivers to have multiple channels. The distribution of the total flow to the individual channels depends on their relative hydraulic characteristics of depth, width...
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...
The Effect of Grain Size Distribution on the Entrainment of Interstitial Water into Overland Flow
Non-point source pollution from agricultural runoff is an important environmental problem. This experimental study considers the effect of media heterogeneity on the entrainment of interstitial...
Water Supply and Aeration Demands for Shrimp Farms
A computer model was developed simulating flow and aeration requirements for a range of farm sizes, from 50 to 2000 hectares. Climatic effects and water quality upset conditions were included...
Forces Acting on a Vortex-Excited Vibrating Cylinder in Planar Oscillatory Flow
An experimental investigation into the vortex-excited vibration of a circular cylinder in planar oscillatory flow has been made with emphasis being placed on the amplification of the forces...
Modeling of Surface Vortices in Unsteady Flow
Hydraulic model studies of lock filling and emptying systems include investigating vortex tendencies at the intake vincinity during filling. The flow at the intake vicinity is unsteady...
