Delineation of groundwater potential zones in the hilly topographic region of Serchhip, Mizoram, using Geospatial and analytical hierarchy process

Groundwater is the most important source of freshwater next to the surface water. Delineation of groundwater potential is critically essential, particularly in hilly complex topographic regions, where the surface water dries up during the dry season. The present study aimed to delineate groundwater potential areas to address the issue of water scarcity in the Serchhip district, Mizoram. The integration of different thematic layers such as lithology, Normalized Difference Vegetation Index (NDVI), rainfall, slope, soil texture, geomorphology, drainage density, lineament density and Topographic Wetness Index (TWI), the groundwater potential zone layers was prepared by Analytical Hierarchy Process (AHP) method. The groundwater potential zones (GWPZ) were classified into five: poor, fair, moderate, good, and excellent. The study revealed that the moderate-good zone occupied about 79.27 % (1126.77 km2), and the fair zone covered an area of about 9.52 % (135.3 km²), while the poor area was only 5.30 % (75.3 km²) out of the total study area (1421.5 km2). The demarcation of groundwater potential zones in Serchhip, Mizoram, served to combat water scarcity in mountainous areas. The amalgamation of geospatial data and AHP methodologies offered pivotal insights for the sustainable management of water resources, facilitating informed decision-making and conservation endeavours amidst the challenges posed by climate fluctuations and population expansion.  

Modelling and Analysis (Gravity & Seismic) Of Two Different Buildings with and Without Infill Walls Using Software SAP 2000

Reinforced Concrete framed structures are consistentlyincluded in the building developments which are framed as exposed edge structures and for the most part the casings in the uncovered edge structures are filled by workmanship infill or concrete pieces in numerous nations arranged in seismic districts. The nearness of infill divider in RC Frames offers a monetary and tough arrangement as well as improving the quality and solidness of edge by acting like pressure strut in the middle of the void space of segment and shaft in RC Framed structures and exchange the compressive powers starting with one hub then onto the next. It is plainly frames that the nearness of infill divider has noteworthy basic ramifications within the sight of buildings in earthquakes (like Bhuj quake). The execution of RC Framed buildings with and without infill walls is seen by this investigation. Here investigated and frame the workmanship infill walls as pressure struts by receiving identical corner to corner strut idea, to evaluate the contribution of infill divider in seismic resistance of customary RC Buildings. Modeling the two diverse multi storied buildings (G+5, G+9) with and without infill walls and planned it and investigated for horizontal burdens utilizing programming (SAP 2000). Modeled the strut buildings as double strut model, triple strut models for both the structures and looking at the got comes about because of the modernized model investigation for with and without infill divider structures. At long last, we check the outcomes for add up to weight of building, Base shear, time period, and zone of steel required by building and model interest mass proportion for the looking at of result
