This study attempts grade-wise mapping in a limestone mine in Ariyalur, Southern India, and in the iron ore mines of Noamundi, Eastern India. After noise removal in the Sentinel 2A (multispectral) and EO-1 Hyperion (hyperspectral) image datasets, spectral matching is performed using the Jeffries-Matusita (JM) distance, Spectral Correlation Mapper (...

Correct selection of similar materials is key to geomechanical model tests. According to similarity theories, a novel similar material for the fluid–solid coupling model test was developed to solve problems of low similarity and poor stability. A similar material is mixed with calcium carbonate, white cement, paraffin, quartz sand, silicone oil, ta...

Natural toxic elements such as arsenic and mercury are widespread distributed in nature and the over accumulation of them usually has adverse effects on both environment and human beings. Therefore, to assess potential toxicity of these elements in natural environment such as water, soil, and stream sediment, it is significant to determine threshol...

Miandoab plain aquifer, with 1150-km2 area, supplies a significant portion of the agricultural and drinking water demands of the area. In recent years, it has been faced with a significant decline in water level as a consequence of the deterioration of groundwater quality. Therefore, a scientific study of the groundwater resources in the study area...

Expansive clays cause problems throughout the earth, in particular for the locations in arid or semi-arid climate. Ankara (Turkey) is in semi-arid climate and change in moisture content of the reddish-brown expansive Ankara clay causes swell-shrink related movements and damages on lightweight structures. Over-estimation of undrained shear strength ...

Experimental studies on tunneling and other kinds of underground engineering using similar materials are an important technique for investigating relevant problems in civil engineering. Compared with case studies in real-world engineering construction, laboratory experiments have three distinctive characteristics: high maneuverability of the proced...

The methods commonly used to prepare fractured structures can be used to form only 2D cracks or holes in rock specimen. In engineering, however, the geological structures considered usually have prominent 3D characteristics. To prepare specimens with 3D internal structures, a method to form real cavity in a hard-brittle rock-like model is proposed ...
