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...
Land Use Change and Soil Erosion Hazard in the Zambezi Basin
An experimental model for estimating soil erosion hazard in southern Africa (SLEMSA) was linked to a raster based Geographical Information System. Soil erosion hazard maps were constructed...
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 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...
Vertical Transport in the Vadose Zone by Fingering
Water containing contaminants may infiltrate through the vadose zone as a series of fingers which result from a hydrodynamic instability initiated at an interface in which a fine textured...
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...
Moving Toward the Millennium
The last decade of the 1990's is just beginning and paradoxically the water resources readily available to Clark County, Nevada are just ending. In a few short years Nevada's...
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...
Design Storms and Sizing of Flood Control Facilities
Design stroms which embody the rainfall characteristics of an area are used for the sizing of drainage facilities. The selection of a design strom may significantly influence the design...
A Value Engineering/Risk Analysis Approach to Operation and Maintenance of Hydraulic Structures
Value engineering is an objective, systematic method for minimizing cost of a system. Risk analysis is a method of quantifying uncertainties or probabilities of possible economic loss,...
Estimation of Expected Damages, Indemnification Costs and Joint Probabilities of Dam Failures
This paper describes three methods to evaluate structural options for the rehabilitation of an existing dam using the dollar-denominated risk and capital cost associated with each option...
GIS: Easing Infrastructure Management
GIS provides an ideal means for city planners and engineers to plan construction and maintenance of water-distribution networks, wastewater-collection systems and treatment plants, highways,...
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...
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....
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...
CORMIX2: Expert System for Multiport Diffuser Discharges
The Cornell Mixing Zone Expert System (CORMIX) is a series of software systems for the analysis, prediction, and design of aqueous toxic or conventional pollutant discharges into watercourses,...
Failure Modeling of Hydraulic Systems
Techniques of survival analysis are investigated for modeling the failure of hydraulic systems. The Proportional Hazards Model has the advantage of being able to separate the effects on...
Optimal Design of Highway Drainage Structures
Hydraulic design of a bridge or culvert using a risk-based approach is to choose among the alternatives the one associated with the least total expected cost. In this paper, the risk-based...
Conceptual Evaluation of Dam Safety by Instrumentation
The criteria governing the design of dams can frequently be imprecise. One of the most practical methods of evaluating dam safety in the dam safety surveillance programs is to check the...
