Evaluation of the Return Period of the September 1992 Flood in Genova, Italy
The September 1992 flood in Genova caused great damage and loss of life. The flood peak, at the outlet of a 12.5 km2 basin, was estimated at 200...
Time-related Deflections of Cantilever Bridges
Many prestressed concrete bridges with spans between 100 and 160 m have been built in the Netherlands. The method of construction is the so-called in situ free cantilever construction....
The Usefulness of Stone Columns to Reduce Settlements and Distortions - A Case History
A shed had to be built as a storage area for ashes and gypsum resulting from the combustion of coal in a power plant in Sardinia, Italy. Two field loading tests have been performed. In...
Settlement of a Silo Subjected to Cyclic Loading
The paper presents the vertical settlement values for a corn silo located at Ca' Mello, close to Porto Tolle (Italy), and compares it with the theoretical results obtained using a simplified...
The Influence of Engineering Judgement in the Settlement Analysis of a Test Fill Near Ch?lon-sur-Sa?ne, France
This paper describes the settlement study for a test fill near Chalon-sur-Saone (France). The soil profile at the site comprised a silty clay layer 4.2 m thick. The elevation of the ground...
Vacuum consolidation Technology?Principles and Field Experience
Vacuum consolidation is an effective means for improvement of saturated soft soils. The soil site is covered with an airtight membrane and a vacuum is created underneath it by using a...
Application of the Diflupress L.D. Field Test to Settlement Calculation
Electricite de France developed a new in situ measurement apparatus (Diflupress L.D.) in order to predict the delayed settlements that can appear under heavy constructions. From the experimental...
Coastal Eutrophication and Temperature Variation
A 3-D hydroecological model has been developed to simulate the impact of climate-change-induced daily temperature variation on coastal water quality and eutrophication. Historical daily...
Two-Dimensional Modelling of Flow in the River Sava
On the river Sava near Ljubljana, a sports centre with a kayak racing channel was built in 1948. For the world championship in kayak-canoe racing in 1990 totally new racing channel had...
Comparison of Current Meters Used for Stream Gaging
The U.S. Geological Survey (USGS) is field and laboratory testing the performance of several current meters used throughout the world for stream gaging. Meters tested include horizontal-axis...
Integrated Planning for International River Basin
The integrated development of the Vardar/Axios Basin includes a system of projects scheduled to meet the needs and aspirations of Yugoslavia (in particular, the former Socialist Republic...
A model to describe the fate of agricultural pollutants
The distributed parameter hydrological model CEQUEAU is coupled to nitrogen and pesticide sub-models to study agricultural non-point pollution at the watershed level. This developing tool...
Roughness Coefficient in Mountain Rivers
River discharge estimations require an evaluation of the river flow resistance that generally is related with Manning's roughness coefficient. The literature suggests different ways of...
Hocking River Sedimentation Study
The channel improvement project located on the Hocking River in Athens, Ohio is estimated to have prevented over 68 million dollars in flood damages since its completion in 1971. However,...
A Watershed Model for Estimating Suspended Sediment Hydrographs
A mathematical model was developed to estimate soil detachment and transport and, consequently, suspended sediment hydrograph for single storms on a watershed basis. In this linear cascade...
Poland Gets Moving
Poland's transportation network is a victim of two world wars, foreign domination, and neglected maintenance, but there are ambitious plans to rebuild the road and rail systems....

Reduction of Head Losses in Tunnels by Means of Shotcrete
Head losses in blasted rock tunnels conveying water to hydropower stations often significantly reduces the energy production in the plant. Typical values on the head losses in tunnels...
Active Tunnel Design?A New Concept for Predesign, Contractual Lay-out and Construction Management
Active tunnel Design is a new concept for design, layout of specification and contract, and for construction management of tunnels and underground carverns. Investigations yeild more information...
Development of Mechanized Wet Mix Shotcrete Application in Norwegian Tunnelling Industry
From 1971 to 1980 wet mix shotcrete won the Norwegian market 100%. In the same period hand held spraying was replaced by hydraulic manipulators. From 1980 to 1986, steel fibre use increased...
