Analysis of Rainfall through Space - Time during 1999-2014 in Salem District, South India

Analysis of Rainfall through Space - Time during 1999-2014 in Salem District, South India



P.Arulbalaji, B.Gurugnanam



The present study deals about the Rainfall assessment using various
recent techniques with the help of remote sensing and GIS in Salem
District, South India. The rainfall assessment carried over a period of
16 years from 1999 to 2014, which are clearly analyzed by using mean
annual rainfall, mean seasonal rainfall, mean annual rainfall
variability, mean seasonal rainfall variability, mean annual
precipitation ratio and mean seasonal precipitation ratio methods. The
methodology adopted based on literature study and which has given an
accurate results. Therefore, the output shows that the study area has
received 1 %, 19%, 41% and 39% of precipitation in winter, summer,
southwest and northeast season respectively and the average annual
rainfall is relatively more in N and NE and it is gradually decreases
the eastern, western and southern parts of the study area. The rainfall
variability indicates more than 100% in winter season except Nangavalli
which is indicate the not dependable rainfall and other three season’s
rainfall variability less than 100% except Veeraganoor station, which is
indicate the dependable rainfall available during these period. The
precipitation ratio is less abnormality during SW and NE season and high
abnormality during summer and winter season. Finally, rainfall
variation assessment depicts that the rainfall conditions in Salem
district is normal and fluctuation depends upon time and space.

The Ecological Impacts of Light Pollution at Night-time a Mechanistic Appraisal

The Ecological Impacts of Light Pollution at Night-time a Mechanistic Appraisal Abdullahi MG, Roslan U, Kamarudin M. K. A. Artificial light at night and its negative consequences are of great interest in the fields of Ecology, Human Geography Astronomy, and Human Health. Most of the studies to date concentrated on the influences of light pollution has on our ability to view the night sky, on biodiversity, and ecosystems. Though, in recent years, with the use of new technologies sensors, which provide accurate information for determining of night lights at the area, most consideration were given for estimating artificial light at night within the urban areas. In this study, urban night lights within the cities of Nigeria was evaluated by monitoring data from the ground measurements using Sky Quality Meter (SQM-LU-DL) devices. Besides, the SQM was used at the zenith (upward direction) for maximum evaluating of artificial light at the sites. Differences in night sky bri...

Land Use Land Cover Change Detection by Using Remote Sensing Data in Akaki River Basin

Land Use Land Cover Change Detection by Using Remote Sensing Data in Akaki River Basin Adimasu Woldesenbet Worako   Land use land cover change (LULCC) is the result of the long time process of natural and anthropogenic activities that has been practiced on the land. GIS and remote sensing are the best tools that support to generate the relevant land use/cover change in the basin. This study was conducted in the Akaki River basin to detect land use land cover changes within the 30 years period (1985-2015) by using landsat imagery data acquired from the GCF. Supervised maximum likelihood algorithm classification were deployed to classify land use/cover into four prominent land use groups and data’s were processed by using ERDAS imagine 2014 and ArcGIS10.1 software. In the basin dominant LULC was agricultural land use which accounts around 56.28% and the second largest is built-up area by 31.51% and the rest, forest(11.9%) and water body(0.31%) coverage were takes t...
