  • Employing Digital Elevation Model (DEM) for Floodplain mapping with
           applications of HEC-HMS, HEC-RAS, and ArcGIS : A Review

      Abstract: Disasters caused by climate change have wreaked havoc on the environment around the world in recent decades, to the point that even deserts have been flooded. Considering floods as a major disaster across various countries, this research has accumulated different methodologies and techniques to analyze flood mapping according to geography of many regions across the world. This paper discusses about flood plain mapping and analysis of the past two decades. Recently with the help of satellite images and the application of remote sensing and GIS this concept is widely used by various researchers. To simulate these flood plain areas, software such as HEC-HMS, HEC-RAS and ArcGIS are quite popular and widely used. The purpose of this review article is to divide the research into four primary sections: floodplain mapping, analytic method, digital elevation model, and software used.. It was observed that globally according to site and climate conditions the effect of floods changes geographically and as a result, the approaches and techniques employed by various researchers differ from one location to the next and according to their research goals. As a consequence, gaps have been identified, and the authors have applied strategies to tackle their problem. This document serves as an overview of the research's important literature review

  • Petrographic Study of Basalt from Adi hill, Nipani, Belgaum District,
           Karnataka, India

      Abstract: Adi is a rural region in India's Karnataka state's Belgaum district. The Co-ordinates are 16.4962° N and 74.3727° E. The area is underlain by basaltic lava flows, known as Deccan Trap. Plagioclase and pyroxene make up the majority of the fine-grained volcanic rock known as basalt, which also contains biotite, olivine, and quartz. Basalt is composed of calcic plagioclase and pyroxene. Plagioclase is seen in the form of laths. Common pyroxene found in basalts is augite. Along with this modal analysis of these rock samples has been carried out. From this it is evident that plagioclase is most abundant mineral followed by augite. Iron oxide and glassy material is also present in considerable amount followed by biotite. Olivine has been found exceptionally. Basalt samples from different flows show different textures, like porphyritic, intergranular and sub ophitic. Laterite covers the uppermost basaltic flow. The flows are equivalent to Panhala Formations of Wai Subgroup.

  • Multi Criteria Suitability Analysis for Identifying and Selecting Suitable
           Site/s for Solar Farm Development; Somali Region, Ethiopia: A Decision
           Support Approach

      Pages: 25 - 54
      Abstract: By now, the world is shifting its energy source from nonrenewable energy to renewable energy in need of sustainable energy source, mitigating environmental and climatic problems. Renewable energy sources are sufficient and environmentally friendly. Ethiopia has a significant potential in hydro, solar, wind, and geothermal energy source. Particularly, in the study area, Somali region, there is significant amount of solar energy potential ranging from a minimum of 1,772.557983 Wh/m2 (approximately 1,772 Kwh/m2) and maximum of 2,476.39502 Wh/m2 (approximately 2,476 Kwh/m2) per year. Even though, the zone has not given sufficient consideration to its opportunities. But, currently, in the country’s ten year strategic plan, the government gives significant attention to invest on this abundant energy source. To make this abundant amount of solar energy useful and functional, identifying and selecting suitable site/s for the development of solar power plants are very crucial. This paper focuses on suitability analysis for identifying and selecting suitable site/s using Geographic Information System (GIS) and multi criteria based Analytical Hierarchy Process (AHP) by taking into account factors like solar energy potential, slope, aspect, land use land cover, proximity to road, proximity to electric main grid and distribution lines, proximity to river/streams, technical and socio economic aspects. AHP method was adopted to determine the weight of each criterion. Suitable areas were identified through a linear overlay of spatially distributed weighted criteria using a GIS solution. Criteria GIS layers were converted into rated value layers using four grades and by combining the rating value layers with the weightings, a site suitability map was developed, in high, moderate, low and unsuitable. Accordingly, in the study area, nearly about 11.51% highly suitable for solar farm development and about 77.63% of the study area is moderately suitable. Thus, with some modifications and investment 89.14% of the study area is suitable to deploy solar farm. Contrary to this 10.85% is less or unsuitable for the development of solar farm in the region because of some restrictive factors which are not suitable for solar farm installation and development.

  • Correlation Between Tree Diversity and Spectral Variables of Sentinel-2
           Images: A Study of Langtang National Park, Nepal

    • Free pre-print version: Loading...

      Authors: Anisha Puri, Babatunde Adeniyi Osunmadewa, Ram Asheshwar Mandal, Dr. Elmar Csaplovics
      Pages: 55 - 66
      Abstract: This study was objectively conducted to explore the tree diversity of Langtang National Park (LNP), Nepal and show the correlation between spectral variables and tree biodiversity. Sentinel-2 MSI of LNP in Nepal was acquired from https://scihub.copernicus.eu/. Total 60 samples were collected from forest. Pearson correlation was established to show relationship between tree species diversity and reflectance values. Bagging LASSO algorithm was used to validate the model. Result shows that Shannon-Weiner index was ranging from 2.9 to 3 and it was the highest in dense forest. Altogether, there was 18 tree species in LNP. The highest importance value index was 79.64 of Rhoderndron arborum and it was the least around 3.44 of Prunus cornuta. Classified map of tree species of LNP showed high Kappa statistics with 0.7. The NIR band B6, B7, B8 and B8A performed high separability for tree species. High reflectance values were recorded of Betula alnoides, Qurecus semicarpofolia and Castonopsis hystrix but it was the lowest of Querus lamellose. The higher reflectance value was recorded of Juniperus indica and Sorbus cuspidate in case of shortwave-infrared spectrum (SWIR, Band 11) and SWIR2 (Band 12). The highest negative correlation was recorded between Simpson’s index and B7 with -0.386 and it was the highest positive correlation between Shannon-Weiner Index (H’) and B8 of Sentinel-2 with 0.361. The highest correlation was found between Simpson index and B8A_Entrophy with -0.365. Bagging LASSO model performed better prediction to show correlation between biophysical characteristics and reflectance value of remotely sensed data.
