Seismic Strengthening of Existing RC Buildings
Seismic strengthening of existing reinforced concrete (RC) frame buildings by the use of steel braces or panels was studied experimentally. A special joint between steel elements and the...

Construction QA/QC Systems that Work
Case Studies
Four case studies discuss the issue of responsibility for quality assurance and quality control by describing actual situations where quality work is being done in the field. The case...

Geographic Information Systems: A Planning Tool
Geographic Information Systems provide an opportunity for water resource planners to examine potential impacts of proposed plans early in the study process. Conflicts can be identified...

Analysis of Reservoir Operations on the IBM-PC
The optimization of reservoir operations is a major economic concern. This paper contributes a computer software package, SPORO, written for the IBM-PC, for the stochastic optimization...

Forecasting Demand for Urban Water
The purpose of this study is to assess current water use forecasting practice in the US Army Corps of Engineers and to recommend additional approaches which best satisfy current requirements....

Prototype Laser Fluorescence/Fiber Optics Groundwater Contaminant Detector
Laboratory testing of a prototype field-portable instrument for in-situ laser fluorescence analysis of groundwater contaminants using fiber optics is discussed. Gasoline, gasoline components,...

Computer Simulation of Lime-Soda Softening of Cooling Waters
A computer model is developed to simulate the process of lime-soda softening of cooling waters. Results from the model are compared with those from a laboratory experimental study using...

Theoretical and Experimental Evaluation of Single-Activated Sludge
The objective of this paper is to discuss the results of operating a laboratory bench scale compartmentalized activated sludge unit operated at a hydraulic detention time ( theta ) of...

Design and Operation of Belt Filter Presses
This report summarizes the findings of a study performed to identify and concisely document improved design and operation procedures for belt filter presses for municipal sludge that have...

Foundations in Permafrost and Seasonal Frost
The papers in this volume cover the following subject areas: A method that utilizes a decision matrix diagram for selecting the most suitable and economical foundations for construction...

Drilled Piers and Caissons II
Drilled piers or caissons, also called drilled shafts or bored piles, have long been a very cost effective foundation solution for many soil profile and load situations. A distinct advantage...

Picture Index for Field Verification of Crop Coefficients
A picture index has been developed for eight irrigation crops to obtain reliable, rapid, and low-cost field determinations of crop growth stages and corresponding crop coefficient (Kc)...

Formation of a Caribbean Coastal Management Unit
Rational management of Caribbean coastal areas is hindered by the poor state of knowledge of coastal ecosystems and by shortage of manpower with expertise in coastal management. To address...

Histological Markers of Environmental Effect
This paper evaluates the potential use of histopathology in determining the health of wild fish relative to the quality of the water in which the fish are residents. This paper examines...

Guidelines for Beach Nourishment: A Necessity for Project Management
This paper outlines detailed studies that have been performed on recently completed projects to assess the fill sediment redistribution and profile response. This compilation of data has...

Experimental Study on Sandbag Stability and Runup
Sandbag model tests are performed in a wave flume to examine the effects of berm-type slopes on the stability of sandbags and wave runup as compared to uniform slopes. Measurements of...

Experimental Studies of Coastal Process and Improvement Works on Xiaodinggang Coast
The field observation and investigation in recent years show that the coast erosion in the area is mainly caused by rapid reduction of sediment supply. The deposit materials are uplifted...

Coastal Zone Management in Emilia-Romagna, Italy
The beaches of the seaside resorts in the Emilia-Romagna region are of great importance to the regional economy. During the last decades, certain natural and man-induced developments have...

Equilibrium Beach Profiles: Prediction of Coastal Erosion Due to Severe Storms
This paper describes a method that calculates coastal erosion due to severe storms. The equilibrium beach profile concept used in this study was developed by Swart. The agreement between...

Anadromous Fish Impacts at Proposed Hydroelectric Plants
This paper describes a series of field techniques successfully used by the authors to determine a minimum flow downstream of hydroelectric plants. The minimum flow of water required for...
