Assessment of hydropower potential using spatial technology and SWAT modelling in the Mat River, southern Mizoram, India

Abstract

In this study, a hydrological model and spatial technologies have been employed to assess water availability in the Mat River basin, southern Mizoram, India. Furthermore, the results obtained from the SWAT (Soil and Water Assessment Tool) model, satellite data and GIS tools were utilized to identify the hydropower potential in the basin. Thirty three sites with hydropower potential were identified within 147 km 2 of the Mat River basin. A total of 3039, 1127 and 805 kW can be harnessed with 50, 75 and 90% dependability, respectively. The study revealed that the hydropower potential of a river basin can be correctly assessed by employing a digital elevation model, stream network data and a hydrological model, such as the SWAT model, within a GIS framework. Evaluation du potentiel hydroélectrique utilisant la technologie spatiale et le modèle SWAT pour la rivière Mat, dans le sud Mizoram, Inde Résumé Dans cette étude, un modèle hydrologique et des technologies spatiales ont été employés pour évaluer la disponibilité de l'eau dans le bassin de la rivière Mat, dans le sud Mizoram, Inde. En outre, les résultats obtenus à partir du modèle SWAT (Soil et Water Assessment Tool), les données satellitaires et des outils de SIG ont été utilisés pour identifier le potentiel hydroélectrique dans le bassin. Trente-trois sites à potentiel hydroélectrique ont été identifiés dans les 147 km 2 du bassin de la rivière Mat. Un total de 3039, 1127 et 805 kW peut être exploitée avec respectivement 50, 75 et 90% de fiabilité, L'étude a révélé que le potentiel hydroélectrique du bassin de la rivière peut être correctement évalué en utilisant un modèle numérique de terrain, le réseau hydrographique et un modèle hydrologique, tel que le modèle SWAT, dans un système SIG.

Identification of Potential Locations for Run-of-River Hydropower Plants Using a GIS-Based Procedure

“…Goyal et al [18] used a multi-criteria approach based on the integration of an advanced methodology for preparation of geospatial raster/grid data and the SWAT model in order to detect potential hydropower locations in the Mahanadi river basin (India). Additionally, Pandey et al [19] used SWAT within a GIS framework in order to assess water availability for hydropower in the Mat River basin, India. The SWAT model has been widely used to simulate the hydrological processes in studies with different purposes, providing reliable estimations of river flow in ungauged basins [20][21][22].…”

“…The flow-duration curve allows for one to estimate the river flow corresponding to different degrees of dependability. In this study, the hydropower of the potential sites has been evaluated while considering the 50% and the 75% dependability river flow values [17,19].…”

Assessment of Hydropower Potential Using Geospatial Technology in a Case Study of Guna-Tana Landscape Upper Abay Basin, Ethiopia

“…Hydropower is environmentally friendly, cost effective and, unlike oil and other commodities, independent from international trade. Construction of a hydropower project requires proper planning and a detailed survey of the topography and ow availability within the basin (Pandey, A. et al, 2015). Hydropower development in hilly terrain requires a thorough study of the geology, topography, and land use patterns, availability of resources, infrastructure and socio-economic activities (Pokhrel, Y., et al, 2018).…”

Identification of Owan Catchment Run-of-River Hydropower Potential Sites in Benin Owena River Basin Nigeria Using GIS And RS Procedures

“…Improvements in GIS, RS, and hydrological modeling offer genuine, modern, and suitable data in the evaluation of hydropower resource potential. GIS environment makes it easier to collect and scrutinize information on land-use practice, geology, topography, and river morphology compare to regular field survey because GIS can deal with catchment characteristics with respect to a specific location and make available analysis about the impact zone of the hydropower project (Pandey et al 2015).…”

“…(Chandra et al 2013) applying geo-spatial techniques in Andhra Pradesh state spotted suitable location for micro-hydropower station locations. (Pandey et al 2015) in their study of Mat River Basin, southern Mizoram, India employs spatial technologies and hydrological models to evaluate water accessibility, and obtained results show hydropower potential of the basin was successfully investigated utilizing GIS tools, satellite data, and SWAT (Soil and Water Assessment Tool) model. Also, RS data and GIS-based technologies have gained more influence across various countries with their application in spotting and selecting hydroelectric prospects of distinct classes, for instance, pumped storage hydropower systems in Ireland (Connolly et al 2010), small run-of-river (ROR) schemes in Thailand (Rojanamon et al 2009), US (Hall et al 2004) and Brazil (Avila et al 2007), and water retention facility (dams) in India (Kusre et al 2010), Brazil (Larentis et al 2010), South Korea (Yi et al 2010) and South Africa (Ballance et al 2000).…”
