An Improved Method for Measuring System Performance of Hydraulic Infrastructure Systems
Due to the public awareness of the importance of functioning of hydraulic infrastructure systems and the serious consequences caused by their failure, many researches were undertaken to...

Prediction of Occurrence and Runoff Analysis of Debris Flow
A debris flow will occur on a slope when the rainfall exceeds a certain value determined by the hydraulic, geological and topographic properties of the slope. To estimate this critical...

Integration of Environmental Management with Reservoir and Power System Operations
Two examples related to the Tennessee Valley Authority's reservoir and power systems operation with environmental performance and management as major goals are given in this paper. One...

Time-Dependent Landslide Probability Mapping
Case studies where time of failure is known for rainfall-triggered debris flows can be used to estimate the parameters of a hazard model in which the probability of failure is a function...

Operation of a Real-Time Warning System for Debris Flows in the San Francisco Bay Area, California
The United States Geological Survey (USGS) and the National Weather Service (NWS) have developed an operational warning system for debris flows during severe rainstorms in the San Francisco...

Structural and Non-Structural Debris-Flow Countermeasures
Debris-flow can potentially occur for almost any torrents whose gradient is steeper than a given critical value and the frequency at which the debris-flow occurs depends on geological...

Evaluation of Hydraulic Structure Reliability Considering Uncertainties in Hydrologic Models
Uncertainties in a hydrologic model give rise to uncertainty in model outputs which, in turn, can be used for reliability-based design and /or evaluation of hydraulic structures. This...

Analyzing Uncertainty of IUH of Nash
Uncertainties in hydrologic modeling are the primary factors affecting the reliability of hydraulic structures. Among various hydrologic rainfall-runoff models for engineering applications,...

Assessing the True Value of Flood Control Reservoirs: The Experience of Folsom Dam in the February 1986 Flood
Over the last 40 years considerable public investments have been made in large flood control storage reservoirs throughout the U.S. and internationally. These projects were typically designed...

TRIM?3D: A Three-Dimensional Model for Accurate Simulation of Shallow Water Flow
A semi-implicit finite difference formulation for the numerical solution of three-dimensional tidal circulation is discussed. The governing equations are the three-dimensional Reynolds...

Integrated Planning Analysis for an Aggregate Mine
Planning and design work of an aggregate mining facility within the Sutter Bypass, a key component of California's flood control system, is being performed by multidisciplinary team of...

Field Examination of a Distribution System Water Quality Model
In the aftermath of the Safe Drinking Water Act (SDWA) of 1974, numerous models have been established to assess the quality of water and simulate its deterioration in distribution systems....

The EUR Water Station in Rome?Italy
The paper deals the new steel Water Centre realized by ACEA in Rome. The Water Station is destined to manage the water consumption of around 500,000 inhabitants with an output of 3,900...

Vortex Spillway: Test Study on a Hydraulic Model
The paper deals with an experimental study on a model of the forced vortex of Eur hanging reservoir realized by ACEA (Rome). Some vortex characteristics are investigated and, in particularly,...

Optimizing Water Transfers in Urban Water Supply Planning
A number of water supply agencies in the Western United States have begun to integrate water transfers into their overall water supply planning, including the use of transferred water...

Hydraulic and Water Quality Reliability and Resiliency for Water Distribution Systems Under Random Demands
This paper develops a preliminary method to evaluate the reliability and resiliency of water distribution systems under random spatial and temporal demand patterns, including random fire...

GIS and SWMM Applications in Developing the Lake Houston Watershed Management Program
The City of Houston has undertaken the task of developing a Watershed Management Program for the 2,828 square mile lake Houston Watershed in an effort to prevent future degradation of...

Interaction of Steel Structure and Composite Supercolumns in Spine Structures
Modern architecture has departed from uniform rectangular cigarette boxes for high-rise buildings. A structural system which goes uninterrupted through the common denominator of the varying...

A New Method from China to Determine Load-Carrying Capacity for CFST Members
The most common research method for CFST (concrete-filled steel tubular) members is to study the behaviors of the steel tube and the core concrete separately, then add them together to...

Hybrid Lifted Structure for the Collserola Tower
The structure of the 300 m. Collserola Tower is a hybrid system formed by three combined structural systems consisting of: - a very slender cylindrical concrete shaft: - a large steel...
