Gravity survey is one of the passive geophysical techniques commonly used to delineate geological formations, especially in determining basement rock and overlying deposit. Geologically, study area made up thick quaternary alluvium deposited on top older rock. The Muda River basin constitutes, approximately, more than 300 m unknown type. Previous studies, including drilling geo-electrical resis...

Entomologist, Spirochetosis Transmission Enquiry Calcutta School of Tropical Mcdicinc. In October 1929, whilst on leave, I carried out a study of the anopheline fauna and malaria in Blmgalpur. The results of this investigation may be of some interest, as there is no previous detailed record of the anopheline fauna nor of the malaria of the place. Bhagalpur, the chief town and administrative hea...

This article proposes hybrid fiber-reinforced concrete (HFRC) mixed with polyvinyl alcohol fiber (PVA) and polypropylene steel (FST) as a wall construction material to improve the bearing capacity durability of frozen shaft lining structures in deep alluvium. According stress characteristics engineering environment lining, strength, impermeability, freeze–thaw damage, corrosion resistance are t...

Internally oscillating cycles of cutting and filling occur naturally in many coupled geomorphic systems. As a demonstration, we have modeled stream entrenchment and backfilling where alluvial systems couple to uplifting mountain blocks. This simple model tracks bedrock stream erosion and transport of alluvium to base level. Internal oscillations arise from coupling of a kinematic wave model for...

The north-central zone of Chile is described with respect to groundwater supply problems. In this region, groundwater is almost exclusively obtained from the thin alluvium in the main transverse valleys, which descend from the Andes in those sections where the valleys cross the northerly trending "central valley." Because of the steep groundwater gradients prevailing, the groundwater resources ...
