Flume Experiments on Debris Flow
With the different characteristics of grain motion in debris flow, three layers are vertically divided, i.e., viscous collision layer, inertial collision layer and suspension layer. Both...
Conjunctive Use of Surface and Groundwater Resources in the Central Valley of California
California Department of Water Resources (DWR) is evaluating the feasibility of incorporating a conjunctive use program into the State Water Project (SWP) to augment its delivery capability...
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...
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...
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....
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,...
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...
Integration of GIS, Remote Sensing, and Digital Elevation Data for a Hydrologic Model
The Agricultural Nonpoint Source Pollution Model (AGNPS), which was developed by Agricultural Research Service, was used as a test model for assessing nonpoint source pollution. The model...
Application of the Ackers-White Procedure for Transport by Size Fractions and Testing in HEC-6
Modification of the Ackers-White method for the calculation of sediment transport by size fractions has led to a procedure which not only permits such calculations, but also increases...
Municipal Stormwater Management Ordinance Development and Implementation in Pennsylvania
This paper discusses the critical planning and engineering components of a sound stormwater management ordinance and how they can be shaped to avoid commonly encountered basin-wide implementation...
An Expert Advisor for Selective Withdrawal Operations
A rule-based computational advisor that aids in the selection of selective withdrawal operations for project release temperature maintenance is discussed. This advisor couples a one-dimensional...
