Acoustic or phonic pollution is a type of noise pollution caused by noises, a complex of non-periodic sounds with random disagreeable insurgency that affects the psychological and biological state of human and animal organisms. The physical or objective characteristics of the noise are the strength or sound intensity (which depends on the features of the source, the distance and the possibilities of transmission or multiplication), duration and frequency. For the determination of the noise level, sound-meters, whi...

Soil erosion is a naturally occurring process on all land. The agents causing soil erosion are water (especially on sloping land) and wind (especially on horizontally land), each contributing a significant amount of soil loss each year. These factors are responsible for about 84% of the global extent of degraded land, making excessive erosion one of the most significant environmental problems worldwide. Soil erosion is a slow process that continues relatively unobserved, or it may occur at an alarming rate causing...

This paper proposes an evaluation of data acquired with various sensors and used in coastal water segmentation applications. Correct monitoring of coastal changes in dynamic coastal environments strongly depends on accurate and frequent detection of shoreline position. Automatic shoreline delineation methods are preferable, especially in terms of time, cost, labor intensiveness and difficulties of in-situ measurements. Two main issues have been encountered within this application field, the quality of data and the...
