Steep pressure increase and decrease are often generated by such events. This pressure upset quickly propagates over the system along the associated piping. The increasing pressure propagation may cause overpressure problem, while the decreasing pressure propagation may cause vacuum problem and sometimes induce secondary pressure upset due to vapour cavity formation and collapse (vaporization and condensation) at highly elevated portions, dead ends etc. A mathematical model consists of a set of partial differential equations of hyperbolic type, which have been transformed by the method of characteristics into ordinary differential equations which are solved by the predictor-corrector method. The method of characteristics is used to find the pressure increase and decrease and hence help to decide the kind of safety device required in the water mains. Interactive software is developed that provides user to draw network structure of pipelines with components like valves, pumps etc. and also obtain the result in graphs. Thus, allowing user to not only detect faults but also provides information about which anti-surge device is to be used in order to increase the life of water mains.","PeriodicalId":270099,"journal":{"name":"2015 International Conference on Technologies for Sustainable Development (ICTSD)","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2015-02-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"133112690","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}

Wind being one of the most abundant and easily available sources is an excellent alternative to conventional energy sources. Vertical Axis Wind Turbines (VAWT's) are of two type's viz. Darrieus (lift based) and Savonius (drag based). The problem associated with Darrieus is the lack of self-starting while the Savonius has a low efficiency. In order to overcome these flaws, an innovative design has been created by incorporating both the types into one single unique structure not tested before. In this design, the Darrieus blades are helically twisted to get even torque distribution. The Savonius blades are of half drum type and at the center of the assembly. This unique design allows the use Savonius as a method of self-starting the wind turbine which the Darrieus cannot achieve on its own. There are 3 Darrieus blades placed circumferentially and 2 Savonius couples attached perpendicular to each other along the shaft. The cross-section of the Darrieus blades is of NACA-4415. The objective is to eliminate the need for external motors for self-starting purposes and study the performance of the model. The testing of the model was carried out for different wind velocities. Initially the Darrieus and Savonius blades were tested independently and then the new model which combines the two designs was tested.","PeriodicalId":270099,"journal":{"name":"2015 International Conference on Technologies for Sustainable Development (ICTSD)","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2015-02-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"116537538","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}

Runoff prediction and sediment yield estimation using distributed hydrologic modeling requires spatially distributed soil data especially saturated hydraulic conductivity, water content and particle size distribution. Therefore, soil data becomes one of the major inputs in any watershed management studies. The present study was conducted to analyse spatial variability in soil physical and hydraulic properties in Netravati river basin, Karnataka State, India. The spatial interpolation of soil properties was carried out by using three methods such as Ordinary Kriging (OK), Inverse Distance Weighting (IDW) and Radial Basis Function (RBF). Results indicate that soil properties such as %sand, %silt and %clay are highly variable in nature with standard deviation value of 16.08, 13.27 and 8.82. The OK method is efficient in predicting sand, silt, clay and saturated hydraulic conducted. IDW and RBF methods predicted organic matter content and bulk density with acceptable error of 1.084%, 1.09% and 0.05gm/cc, 0.04gm/cc respectively.","PeriodicalId":270099,"journal":{"name":"2015 International Conference on Technologies for Sustainable Development (ICTSD)","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2015-02-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"129477170","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}

Remotely sensed data have played an important role in detecting urban morphologies effectively. Remote sensing datasets contain more information of earth surface as compared with usual urban maps hence used in urban planning and management. Very high resolution (VHR) satellite imageries provide resolution less than 1m. These imageries have enhanced the applications of remote sensing. Timely and accurate information of urban land cover and biophysical parameters is crucial. Earth observations which are being useable play an important role in detecting, management and solving environmental problems such as climate changes, deforestation, disasters, land use, water resource and carbon cycle. With the help of high resolution satellite imageries it is possible to get the details on earth surface. A different approach is used to get the efficient result called Object-based image analysis (OBIA) in which the image is divided into homogeneous regions prior to classification instead of classifying individual pixels. These are called segments, or image objects. OBIA have gain popularity as a method bridging the gap between the increasing amount of detailed geospatial data and the inefficient results of conventional pixel base classifiers.","PeriodicalId":270099,"journal":{"name":"2015 International Conference on Technologies for Sustainable Development (ICTSD)","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2015-02-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"121811758","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}
