| Title | : | Change detection analysis of coastal zone features in Cuddalore District, Tamilnadu using Remote sensing and GIS techniques |
| Country | : | India |
| Authors | : | Balasaraswathi P || Srinivasalu S |
Abstract: Coastal environment is viable to huge changes mainly due to the intervention of humans by urbanization, population and its migration. It is essential to study the landuse/landcover, geomorphology and shoreline using GIS and remote sensing for the Cuddalore coast. Landsat imageries were used for the years 1988, 2000 and 2016. The thematic maps were differentiated and displayed by its evolving changes in coastal zone features. Deltaic plain (53.28%) is dominant in geomorphology class, Agriculture area (33.77 km2) in landuse class, 37.5% (1.63km2) of aquaculture practice and mangrove forest (9.75km2) increased due to its economical and tourism value. The study suggests the use of Landsat imagery for change detection and environmental monitoring assessment of the coast y well ............

| Title | : | Evaluation of groundwater quality in and around Ariyalur of Tamilnadu using Geographical Information System |
| Country | : | India |
| Authors | : | Devaraj N || Chidambaram S || Thivya C |
Abstract: A study has been carried out in Ariyalur region of Tamilnadu for premonsoon to assess the quality of groundwater using geographical information techniques. A total of 71 groundwater samples are collected and pH, TDS, EC were measured in the field. Samples were also measured for major ions (Ca, Mg, Na, K, HCO3, Cl, SO4, NO3) using standard techniques. The ground water quality information maps of the entirestudy area have been prepared using GIS spatial interpolation technique for all the above parameters.The results obtained in this study and the spatial database established in GIS will be helpful formonitoring and managing ground water pollution in the study area.

| Title | : | The Interpretation of Aeromagnetic and Satellite Imagery for Structures in Coincident with Gold Mineralization in Anka Schist Belt, Northwestern Nigeria |
| Country | : | Nigeria |
| Authors | : | Salau, S. L || Danbatta, U. A. || Agunleti, Y. S |
Abstract: Several studies have shown that gold deposits in Nigeria are mainly of orogenic nature. They are structurally controlled and spatially associated with shear zones and hydrothermal veins formed in response to the regional stress field. The Anka schists belt has been mined for gold since the 1940s and continues till date. The workings in recent times are mostly artisanal but it is an area considered by most exploration geologists to hold promise of major gold deposits. This study used aeromagnetic data; sate llite imagery and digital elevation model (DEM) to define lineaments associated with the major Anka fault system (AFS) and their relationship with gold mineralization in Anka schist belt. The total magnetic intensity (TMI) covering the area was processed, filtered and transformed to other grids such as First Vertical Derivative, Analytical signal and Horizontal gradient. While ArcGIS software was used to integrate the various layers of information.The TMI enabled the identification of structures, trends, domains of varying intensities and frequencies. The integration of the deduced deformation and the gold occurrences indicate that the dominant mineralisation is more associated with later stage deformation and less with the more regional long trending Anka fault. The results consistent with the observation of Morey et al (2005) for the Bardoc Tectonic Zone, Eastern Goldfields Province of Western Australia...........

Abstract: This paper presents results of paleomagnetic study of the mbagathi phonolitic trachytes, volcanic rocks of lower tertiary age, dated 5.7 my, from Kenya. Specimens of the mbagathi phonolitic trachytes, from five sites were sampled and treated in alternating field up to 100mT, stable primary components of the natural remanence isolated and various magnetic parameters analyzed. The cleaned mean directions have been classified as intermediate or reversed. The mean direction and corresponding pole position of the phonolitic trachytes, for the reversedly magnetized sites, is calculated at declination.............

Abstract: In this study, data obtained with the aid of an ABEM Terameter (SAS 300C), from twenty-five (25) Vertical Electrical Soundings (VES) stations in Kutunku, with maximum half-current electrodes spacing AB/2, of 170m and maximum half-potential electrodes spacing MN/2, of 7.5m for most of the profiles, were analysed with IPI2Win software. The analysis indicated 3 to 5 geo-electric layers where the former was predominant. The lithologic units showed characteristic layer resistivity ranges of 1.95 - 1360Ωm, 0.4 - 1723Ωm, 7.7 - 180000Ωm and 71 - 44878Ωm for the first, second, third and fourth layers respectively.............

| Title | : | Boda Bodas In Kenya Have Alleviated Boys From Poverty, Idleness And Bad Habits Despite Prevailing Challenges |

| Authors | : | Veronica Onjoro |
Abstract: Beginning of the 1960s, Ugandan smugglers needed a cheap, reliable, and quiet way to move materials between Uganda and Kenya. Cars were too expensive and noisy, and so were motorbikes. Their choice was to use bicycles which, with a little luggage rack behind the seat, were perfect for evading the border police while transporting valuable goods. The idea had an unexpected development. Those bikes were so strong that perhaps were also suitable as taxis to transport people. Michael Lipton, identified rural isolation and distance from urban centers as the real obstacle to the growth of developing countries (Lipton 2014). The gains were lower than those derived from smuggling.............

Abstract: Conduction heat flow study has been done around the Penantian geothermal manifestations, Empat Lawang Regency, South Sumatra. A study was carried out the measurements of surface temperature and temperature gradient. Surface temperature measurement data were used for the determination of the prospect area and thermal conductivity of rocks. Then, the temperature gradient of measurement data were used to determine the value of the geothermal temperature gradient. The physical quantities obtained, was used to calculate the value of the loss energy of heat conduction naturally. The study showed that the amount of heat energy by conduction was ± 28.29043 Watt

Abstract: In the State of Rio Grande do Sul (RS), south of Brazil, was recorded by the Brazilian Institute of Geography and Statistics (IBGE) census a total of 10,6 million of people living in 496 municipalities. The water supply in the mostly of these municipalities is provided by groundwater, constituting an important resource for development of all economic activities. It is known through agencies responsible for monitoring water in the State and through various scientific studies, which are found in various places with groundwater fluoride concentration exceeding the maximum allowable values for human consumption (1,5 mg/L), usually from natural sources (geogenic).......

| Title | : | Assessment of Spatial Sediment Distribution and Deposition in Reservoirs: Case study of Cubuk I & II, Turkey |
| Country | : | Turkey |
| Authors | : | Umit Duru |
Abstract: The amount of sediment deposition in a reservoir is controlled by the type of sediment deposited (suspended or bed load), the detention storage time, the shape of the reservoir, and operational practices. Determination of sediment distribution and deposition in reservoirs are significant issue for dam designers estimating probable lifespan of a reservoir. In this study, Remote Sensing (RS) and Geographic Information System (GIS) software were used to assess sedimentation through time in the Cubuk I and Cubuk II reservoirs via Bathymetric maps. Results indicate that a significant amount of siltation occurred between 1978 and 1983: Cubuk I reservoir accumulated 3 m of sediment within 6 years and Cubuk II accumulated about 10 m. Siltation is the most significant problem in the reservoirs, so efficient siltation management practices should be performed to control sediment accumulation in these human made structures.
