Specific Features of Shoreline Development in Sochi Region and Engineering Methods of Coast Protection
A coast segment from Tuapse City to the Psou River, 113 km long, is extended in this paper. Geological description of the coast has been made, and approximate values of the abrasion rate...
The Flows of Suspended Sandy Material Along the Section of Bulgarian Coast
Combining of available models of elementary hydro- and lithodynamic processes in a single calculation scheme permits to evaluate the volumes of detrital material transported either way...
About Some Dynamic Conditions of the Beach Sedimentary Strata Formation on the Bulgarian Sandy Coast of the Black Sea
Based on detailed studying of the beach sedimentary sequence composition in sections of perpendicular trenches in the western (Bulgarian) coast of the Black sea and comparison with results...
Disposal of Dredged Material from the Estuaries
The silting up of harbours and the lower parts of rivers are serious problems. These problems can be characterized in terms of quantity and quality. Two separated cases are described....
Aquatic Disposal of Dredged Material in the Belgian Part of the North Sea
Extensive research and study on the behaviour of dredged material after dumping in the sea has been conducted on the disposal grounds S1 S2 and Zb Oost located in the southern Bight of...
Utilization of the Coastal Areas for Aquaculture in Nigeria
The current domestic fish production in Nigeria is estimated to be 363,706 tonnes whereas the projected demand is 1,237,000 tonnes. This leaves a deficit in demand of 874,294 tonnes which...
CANUSLANT?An Evolving-Marine Pollution Contingency Plan
The progress of CANUSLANT exercises to data is addressed in this paper. This exercise model can be used to initiate or improve Marine Pollution Contingency planning....
Scaling Laws of Gravity Driven Fingering During Organic Liquid Infiltration
Wetting front instability can occur during vertical infiltration of a liquid into porous media, particularly when a fine soil layer is overlying a coarse layer. The result of this instability...
Infiltration in Two Sand Dune Areas in Saudi Arabia
Field infiltration experiments at several locations in two sand dune areas in Saudi Arabia were conducted. Results of these field tests are compared with predictions of the Green and Ampt...
The Use of Residence Time to Describe a Hillslope
Queueing theory has been applied to the determination of Soil Water Residence Time (SWRT) using an 18 year data set. The calculated SWRTs agree qualitatively with the lags exhibited by...
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...
National Weather Service Operational River Forecasting in a UNIX Environment
The mission of the National Weather Service (NWS) includes providing river and flood forecasts and warnings for protection of life and property, and providing basic hydrologic forecast...
Sacramento Drainage Manual?Hydrologic Procedures
For a period of over two years, HDR Engineering, Inc. (HDR) and HYDMET have been working with the City and County of Sacramento to develop a Drainage Manual. This Manual contains seven...
Sacramento Hydrologic Procedures Interim Adoption
In November 1989, the County and City of Sacramento jointly undertook the development of a manual for the design of drainage and flood control facilities in the region. Significant technical...
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...
Nitrogen and Phosphate in Vadose Waters in Heber Valley
During the last decade best management practices have been gradually implemented in Heber Valley to maintain and enhance the qualities of surface waters that flow into Deer Creek Reservoir....
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...
