U.S./PRC Cooperation on the Three Gorge Project
The Three Gorge Project is the keystone project in developing and using the Yangtze River. It is located on the main stem of the Yangtze River, about 40 km upstream from the Gezhouba Project...
A Laboratory Study of Factors Affecting Wetted Snow Roads
A brief review of the the literature concerning the application of water to the surface of snow roads is presented. It is demonstrated that there is no general agreement on the proper...
Upper Delaware River Ice Control?A Case Study
During February 1981 a castastrophic breakup ice jam occurred along a reach of the Delaware River near Port Jervis, NY, causing 14. 5 million in damages. In February 1982 another breakup...
A Perspective on Landslide Dams
The most common types of mass movements that form landslide dams are rock and soil slumps and slides; mud, debris, and earth flows: and rock and debris avalanches. The most common initiation...
The 1983 Landslide Dam at Thistle, Utah
The Thistle, Utah, landslide began rapid movement on April 13, 1983. The landslide, a reactivation of an estimated 22 multiplied by 10**6 m**3 of old landslide debris, blocked Spanish...
Landslide Damming in the Cordillera of Western Canada
Major landslide dams in the Cordillera are a result of rock slope movements, landslides in stratified Pleistocene deposits, and landslides in till or colluvium in steep mountain watersheds....
Landslide Dams in Japan
Damming of rivers by landslides is common in Japan because widespread unstable slopes and narrow valleys exist in conjunction with frequent hydrologic, volcanic, and seismic landslide...
Landslide Dams in South-Central China
The Yangtze and Yellow Rivers and their tributaries drain mountainous areas of south-central China that are highly susceptible to landslide activity. This paper describes six major cases...
An Expert System for Flood Estimation
This study was made to investigate the feasibility of expert systems for solving certain engineering problems. A prototype system was developed to demonstrate the applicability of these...
New Approaches to Rehabbing Old Dams
The U.S. Bureau of Reclamation takes a look at several new ways of building old dams for maximum flooding. A labyrinth spillway was built at Ute Dam near Logan, N.M. to increase reservoir...
Viscoplastic Fluid Model for Debris Flow Routing
This paper describes how a generalized viscoplastic fluid model, which was developed based on non-Newtonian fluid mechanics, can be successfully applied to routing a debris flow down a...
Flood Risk Below Steep Mountain Slopes
Alluvial fans spread at approximately the critical hydraulic slope below apexes at canyon mouths. Periodic torrents that rage out of the canyons are devastating at the apex and have diminishing...
Generalized Methodology for Simulating Mudflows
In this paper, a one-dimensional dynamic flood-routing model, for non-Newtonian fluid properties, is described and applied to two different mudflow events: Holbrook Canyon, Utah, and Mount...
Parameter Optimization of Dynamic Routing Models
The methodology utilizes approximate cross-sectional properties represented by separate power functions for channel and floodplain, and a very efficient optimization algorithm for determining...
Routing Comparisons in Natural and Geometric Channels
A method of establishing composite geometric cross section shapes hydraulically similar to natural cross sections with flood plains is proposed. The method is based on the nondimensionalized...
Rainfall-Loss Parameter Estimation for Illinois
The U. S. Geological Survey is currently conducting an investigation to estimate values of parameters for two rainfall-loss computation methods used in a commonly used flood-hydrograph...
Remote Sensing Applications in the Model of Runoff Formation in Excess of Storage
The model of runoff formation in excess of storage applied in some humid regions of China is revised in this paper, so that the model can adopt the information provided by Landsat remote...
Solving Stormwater Drainage Problems Through an Area Drainage Master Study Program
The Flood Control District of Maricopa County, Arizona, is the floodplain and stormwater management agency for the most densely populated county in the State. A major new tool being used...
Flood Reduction Efficiency of the Water-Management System in Dade County (Miami), Florida
Two tropical weather systems, Hurricane Donna (1960) and Tropical Storm Dennis (1981), produced nearly equivalent amounts of rainfall in a 48-hour period south of the Miami (Florida) area....
Emergency Flood Management, Salt Lake City, Utah
This paper discusses Salt Lake City's response to the floods of 1983 and 1984. Peaks during these years were very high with historic records being set in both years. Management...
