The Present Condition and Future Prospects of the Shonan Nagisa Plan
The central part of Kanagawa prefecture adjoining metropolitan Tokyo, and facing the Sagami bay is called the Shonan area. Since the 1950', the area's mild climate, abundant greenery and...

Design Manual for Artificial Reefs
Artificial reefs are wave-breaking structures artificially constructed from rubble to mimic the wave-control functions of coral reefs. Since these structures are located below sea level,...

Development of Offshore Breakwaters for the Marine Multipurpose Zone Project
Under these circumstances, the ministry of construction of Japan has launched the marine multipurpose zone (MMZ) project,and is promoting the effective use of seashores facing the open...

Development of the Long Caisson Type Vertical Breakwater
The width of the caisson of a breakwater is calculated based mainly on the wave force expected to act on the caisson. IN this calculation, the assumed wave force is the peak wave force...

Improvement of Terminal Reliability and Travel Time Reliability Under Traffic Management
Terminal reliability and travel time reliability of road networks are proposed as new indicators for road network management and construction. First, the significance of road network management...

Alluvial Fan: Subset Definitions
The Flood Control District of Maricopa County, Arizona recently completed a study whose goal was to identify and describe four alluvial fans for instrumentation and long-term monitoring....

Dynamic Perspective on the Capillary Barrier Effect at the Interface of an Upper Fine Layer with a Lower Coarse Layer
The theoretical principles behind the determination of infiltration rate into a coarse layer overlain by a tight layer are reviewed. As a descending unsaturated wetting front hits the...

Kinematic Mixing in Stratified Aquifers
The mixing process in heterogeneous aquifers is presented as the bending and stretching of material lines. A linear mixing efficiency is defined in terms of the mean values of a unit length...

Practical Experience in the Probabilistic Based Management of Large Water Resources Systems
Probabilistic tools to assist with the management of large water resource systems in South Africa were developed and applied during the last decade. Acceptance today is not only due to...

Urban Wetlands for Multi-Disciplinary Stormwater Management

Polyacrylamide Decreases Furrow Erosion
Erosion from furrow irrigated land is a serious problem in southern Idaho and several other areas. Polyacrylamide, a very long chain polymer, increases aggregate stability and flocculates...

A New Look at the Potential of Hygroscopic Seeding in Summertime Convective Clouds
Hygroscopic seeding was conducted in the sixties and early seventies in the USA, but since then, most cloud seeding efforts have used glaciogenic seeding materials, usually silver iodide...

IRRICAD ? Computerized Irrigation Design
IRRICAD is a software program that helps irrigation designers by using a computerized systems approach to design. The program features drawing CAD input, interpolation of elevation data,...

Soil Bulk Density Sampling for Neutron Gauge Calibration
The ASCE Task Committee on Neutron Gauge Calibration met in Logan, Utah in July 1992 to investigate the various methods of soil sampling, installation of access tubes, effect of various...

Measuring Soil Bulk Density Profiles with a Single Probe Gamma Density Gauge
Calibrating neutron depth gauges for measuring soil water content profiles requires soil bulk density data. In this study, the feasibility of using a single probe gamma density gauge to...

Error Analysis of Bulk Density Measurements for Neutron Moisture Gauge Calibration
Six bulk density sampling methods were evaluated for use in neutron gauge calibration. All six methods provided estimates of bulk density which were generally within 5% of bulk density...
