Abstract Karkheh river’s Delta is located in the west of Khuzestan Plain and can be divided into two smaller deltas; northern delta named as (including Bostan, Sableh Neisan Deltas) southern -e- Noor Delta. Based on Galloway7 classification, river-dominated type (type 1). Considering activity, this to parts; an active part north inactive south. Orton Reading 16 placed fine-grained (muddy) categ...

The engineering behavior of nonplastic silts is more difficult to characterize than is the behavior of clay or sand. Especially, behavior of silty soils is important in view of the seismicity of several regions of alluvial deposits in the world, such as the United States, China, and Turkey. In several hazards substantial ground deformation, reduced bearing capacity, and liquefaction of silty so...

This research describes the goals, design and implementation of a quasi natural gradient, laboratory scale, sand tank (aquifer) model experiment. The model was used to study the transport of an inorganic tracer (Chloride) in groundwater, within a tropical aquifer (porous medium) material. Three-dimensional sand tank (1.8 m × 0.3 m × 0.8 m) experiments were conducted to investigate contaminant t...

SUMMARY This Report describes work undertaken in an attempt to establish the feasibility of using models to investigate the performance of gravel arresters for aircraft. The experiments were designed using the techniques of physical similarity and dimensional analysis, Tests were carried out with 1:9.3 scale models of Lightning and Canberra aircraft in two types of sand, and the results compare...

Bankfull discharge was identified in some 30 gravel-bed rivers representing in total c. 40 gauging stations. The catchment sizes vary from 4km2 to nearly 2700km2. Bankfull discharge value increases with basin size. In the case of gravel-bed rivers developed on an impermeable substratum, the following equation emerges: Qb=0·087 A 1·044. Bankfull discharge recurrence interval was determined by fi...

In geothermal reservoirs, hydrothermal distribution is significant. The most widely utilized reservoirs to date are those of systems, which systems where the reservoir contains steam, water, or a mixture both, depending on pressure and temperature reservoir. One geophysical method that enough map subsurface conditions determine 2-Dimensional Geoelectric using Wenner configuration. This aims stu...

The study aims at measuring the gamma activity concentration (Ra, Th and K) of sub-slab filling gravel of Finnish houses. This study forms a part of a wider study aiming at exploring factors affecting high indoor radon concentrations in Finnish dwellings. The gamma activity and radon emanation were measured from gravel samples sent from 229 Finnish municipalities, the gamma activity was reporte...
