Abebe","doi":"10.21276/IJEE.2017.10.0106","DOIUrl":"https://doi.org/10.21276/IJEE.2017.10.0106","url":null,"abstract":": In the present study landslide hazard zonation (LHZ) was carried out in an area around Alemketema town, central Ethiopia, about 120 km north of Addis Ababa. For LHZ map preparation, GIS based expert evaluation technique was followed. The parameters considered are; slope geometry, slope material, structural discontinuities, landuse and landcover, groundwater, seismicity, rainfall and manmade activities. For landslide hazard evaluation the study area was divided into 273 slope facets and thematic layers on slope facets and intrinsic parameters were prepared in GIS environment from secondary data, topographical map and satellite images. Later, primary data on various parameters was collected facet wise from the field and as per actual observations suitable modifications were made to the thematic maps. Further, geo-processing in GIS environment was done to know the type of parameter classes that fall within each slope facet. Based on the presence of various intrinsic and triggering parameters class within a slope facet, appropriate ratings were assigned to the parameters as per expert evaluation. Later, sum total of all ratings for various parameters form the basis to prepare the LHZ map in GIS. As per prepared LHZ map, 66.9% of the area falls into ‘high hazard zone’ and 33.1% falls into ‘moderate hazard zone’. Validation of this LHZ map revealed that about 80% of past landslides fall within ‘high hazard zone’. This reasonably confirms the rationality of adopted methodology, considered parameters and their evaluation in producing LHZ map.","PeriodicalId":344962,"journal":{"name":"International journal of Earth Sciences and Engineering","volume":"20 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2017-03-06","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"131531269","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The ingredients which are used for this, contribute most optimally and efficiently to the various properties like compressive strength, split tensile strength, flexural strength as well as durability. Appropriate use of supplementary cementitious materials and super plasticiser gives good results. Usually GGBFS and micro silica which are the industrial by- products are used as supplementary cementitious materials to produce HPC. In this paper, study of effect of steel fibres, GGBFS and micro silica on the mechanical properties of HPC M80 grade was performed. Hooked end steel fibre was used. The dosage of fibre was 1%. Water binder ratio was 0.26. Mix was designed as per Indian Standards IS 10262. The mix proportion obtained was 1:1.25:2.3 and the dosage of super plasticiser was 1% . The compressive strength obtained was 10.5% greater than the target strength.","PeriodicalId":344962,"journal":{"name":"International journal of Earth Sciences and Engineering","volume":"45 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2017-03-06","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"128182636","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

India needs to be much more concerned since its vast population largely depends on climate sensitive sectors like hydrology, agriculture, forestry and fishery for livelihood. In these circumstances a study has been carried to find out the impacts of climate change in Sabari sub-basin which involves rainfall-runoff modeling using PRECIS model data. The daily rainfall-runoff modeling was carried out using ARNO model for a period of 39 years (1970 to 2008). Out of 39 years calibration and validation was carried out for a period of 30 years (1970 to 1999) and 9 years (2000 to 2008) respectively. The Regional Climate Model (RCM) data supplied by PRECIS model which have a grid cell size of 50 km X 50 km and contains three different scenario periods i.) Base line period (1961 to 1990) ii.) Mid Century Period (2021 to 2050) and iii) End century period (2071 to 2098). The observed IMD and predicted RCM downscaled data for the base line period (1960-1990) has been compared and found that there is a huge variation in both the temperature and rainfall measurements. Analysis of RCM data reveals that the temperature is alarmingly increasing during the Mid Century and End Century periods. The futuristic hydrological scenarios have been arrived by incorporating the downscaled RCM data with the calibrated ARNO model. From the analysis it is opined that climate change may pose frequent high peak floods that occurs in a short period of time may alter the landuse/lancover conditions and agricultural patterns in the study area.","PeriodicalId":344962,"journal":{"name":"International journal of Earth Sciences and Engineering","volume":"8 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2017-03-06","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"127287923","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
