A simplified climate model with combined atmospheric-hydrologic processes has been developed at the University of California Davis for the study of physical processes related to drought....
Flow through Vertical Barrier Screens?Numerical Model
A simple one-dimensional numerical model based on the energy equation is developed to predict the normal flow distribution through barrier screens composed of several vertical segments...
Preliminary Studies of a Karst Warm Spring in Mt. Kr?uterin, Austria
A warm spring occurs at the west foot of Mt. Kruterin, characterized by relatively higher temperature (17.4?C) and sulfate concentration (162 mg/L) against with the regional background...
Debris Flow Events at Mountainous Creeks near Santiago, Chile- Hydrologic Analysis
One of the most important aspects in relation to peak flows magnitudes generated in mountainous catchments at the western side of the Andes facing the city of Santiago, Chile (latitude...
Sediment Removal from Stormwater Runoff
Sediment traps, also known as baffle boxes, are being used throughout the state of Florida to remove sediment from stomiwater. A baffle box is divided into three compartments by two bathers,...
Filling and Emptying System Model Study for the Innovative Lock Design
Funding constraints have generated innovative ideas regarding the hydraulic system of proposed navigation locks. Two fundamental questions addressed in the innovative lock design study...
Lake Number: A Long-Term Lake Water Quality Predictor
A seasonal maximum Lake number was found to be a good predictor for volume averaged water temperatures, maximum water temperatures near lake bottom, seasonal stratification characteristics,...
Modeling of Rattlesnake Creek Watershed Using Swat Model
Watershed scale models are widely used in design and operation of river basin projects and for guiding public decisions. This paper presents modeling details of Rattlesnake Creek watershed...
Data Analysis for Computer Modeling of Thermal Discharges
Assessment of the thermal discharge impact upon the environment and design of the appropriate discharge structure necessitate a range of data activities, from extensive field measurements,...
Hydraulic Model Study of the Prado Dam Spillway
The existing Prado Dam, located in the City of Corona, CA, is deficient in providing adequate flood protection to the Santa Ana River floodplain downstream of the dam. To provide adequate...
A Combined Physical and Mathematical Modeling Scheme for Kapichira Hydropower Project, Malawi
A physical model and a mathematical model were used to study the flow patterns in a reservoir having a complicated bathymetry. The physical model measurements were compared with the predictions...
Dam Foundation Erosion Study: Pit 4 Scale Model Simulation
This paper describes the results of a sub task of the Dam Foundation Erosion Study, a cooperative research study by Reclamation, PG&E, Colorado State University, and Western Area...
Physical Modeling to Determine Head Loss at Selected Surcharged Sewer Manholes
The head losses at sewer pipe junctions (manholes) under surcharged conditions were measured in a 1:6 scale model of a typical manhole with one main line passing through it and two perpendicular...
Karst Water Inventories Using Thermography
An airborne thermal camera was used to locate springs, swallets, and caves in a karst watershed. The detector was an imaging infrared camera with a temperature sensitivity of approximately...
Modeling Combined Stresses on Aquatic Ecosystems
A mechanistic ecosystem response model is being developed by incorporating exposure/response relationships for selected natural and anthropogenic stresses into an existing hydrodynamic...
Optimal Sizing of Width- and Depth-Constrained Trapezoidal Channels
Open-channels are often designed based on the assumption of uniform flow and normal depth. If a channel is to be lined with a nonerodible material, the dimensions of the channel can be...
Shake, Rattle and Map
Researchers at Stanford's Earthquake Engineering Institute are developing an innovative system that uses geographic information systems to predict earthquake damage. A case study shows...
Quake Proofing a Palace
A $36.5 million renovation of the California Palace of the Legion of Honor included a two-level underground expansion on a very sensitive site and the largest-ever seismic retrofit for...
Bad Vibrations
Insurance companies often hire engineers to investigate homeowner claims of damage caused by vibrations near a blast or construction site. But these engineers often lack the background...
