Meteorological Forcing on Louisiana Wetlands
The open wetland areas of southern Louisiana are vulnerable to meteorological forcing. On the basis of over one year U.S.G.S. funded measurements of atmospheric pressure, air-sea temperature...
Formation of Kolkhida Shore During Sea Level Rise
A reconstruction of the Kolkhida coastline evolution during one of the thermal maximum in Holocene was made on the basis of geological data. These data are taken as a principle in calculation...
Can Statistical Methods Help to Forecast Drought?
Relationships have been developed between rainfall in eastern Australia and both southern oscillation (SO) and sea surface temperatures (SSTs), and between rainfall in Ghana, West Africa...
Modeling Water Table Response to Climate Change in a Norther Minnesota Peatland
Projections of global warming raise questions concerning the fate of wetlands in many parts of the world. In northern Minnesota, there is concern that the nearly 3 million hectares of...
Impacts of Potential Climate Change on Colorado-Big Thompson System Operations
The objective of this study is to examine the response of the Colorado-Big Thompson (CBT) system to specific local changes in climate, using the model CBTAOP to project the operating plan...
How is the Water Quality Affected by Droughts?
The moving average method was applied to daily time series of water quality and flow data obtained from a stream gaging station affected by the 1988 drought in the midwest of the United...
Estimating Runoff from Precipitation and Temperature
Increasing demands for water and the global climate change resulting from the CO2 buildup in the atmosphere require an improved evaluation of surface-water...
Development of Test Procedures for Unbalanced Head Operation of Slide Gates
This paper will discuss the steps taken by the Bureau of Reclamation to develop a standardized procedure for testing unbalanced head operation of high-pressure slide gates for outlet works...
Estimating ET Using Turbulent Coherent Structures
Two methods for estimating sensible heat flux to use in energy balance equations for computing crop evapotranspiration are discussed. The methods use high frequency temperature measurements...
Density Fluctuations and Use of the Krypton Hygrometer in Surface Flux Measurements
The magnitude of the of the Webb et al. (1980) density corrections on water vapor fluxes due to the flux of sensible heat is examined in terms of the Bowen ratio. The correction due to...
Effect of Choptank Watershed Drainage Project on Stream Temperatures
Between 1974 and 1982, the Soil Conservation Service, U.S.D.A conducted a stream study on the Choptank Watershed in Caroline County, Maryland to monitor the effects of channel construction...
A Model for Low-Drag Landslides
Field observations and experimental records indicate that the primary mode of motion of many large landslides is that of sliding rather than flowing. Most of the shear during sliding is...
An Assessment of Fish Entrainment and Impingement Potential for an Offshore Cooling Water Intake in a Tropical Bay
Fish entrainment and impingement potential were assessed for a proposed cogeneration facility on the west coast of Puerto Rico that will withdraw cooling water using offshore intake structures....
Scour at Highway Structures in Tidal Waters
Scour analysis of bridges over tidal waterways uses the same scour equations as for the rivers. However, determining the hydraulic variables to use in the equations is complex. A major...
Bridge Hydraulic Design in Tidal Situations
The analysis of bridge hydraulics and scour potential in tidal waters, in comparison with inland rivers, requires consideration of various additional factors. This paper condenses a simplistic...
Confirmation of Seismic Safety at Stafford Dam
A critical aspect of the North Marin Water District's mission to maintain reliable water supply facilities and water service is periodic assessment and re-evaluation of the seismic safety...
Hydraulic Performance of a Flexible Curtain Used for Selective Withdrawal ? A Physical Model and Prototype Comparison
Reclamation (U.S. Bureau of Reclamation) studied a 1:120 scale undistorted density stratified physical model to develop a lightweight flexible curtain barrier that would control the outflow...
A Flexible Curtain Structure for Control of Vertical Reservoir Mixing Generated by Plunging Inflows
To maintain salmon habitat in the Sacramento River, efforts are being made to pass cold water inflows through Whiskeytown Reservoir, California, with minimal warming. In Whiskeytown, summer...
Seismic Performance and Composite Action of Older Structures
A study into the seismic performance of older steel structures is described. A review is made of the types of steel building construction completed during the period of interest, and the...
Proposal on Story Drift Limit Based on Axial Behavior of Column under Seismic Loads
The main function of columns primarily is to support axial loads both under and after repeated lateral loading from earthquakes. A definition of the story drift limit in any structural...
