A Systematic Review of Water Resources Assessment at a Large River Basin Scale: Case of the Major River Basins in Madagascar

Assessing water resources at a large river basin scale is important for having an idea of the situation and efficient management. What most appropriate approach to assess scale? This paper aims develop systematic review on assessment scale, intending present new method major basins in Madagascar. investigates 40 articles from Google Scholar, Web Science, PubMed databases, 2000 2022. has demonstrated necessity An improvement use multiple GCMs SWAT models within was found necessary allocating regimes among upper lower reaches. Water allocation scarcity level could be addressed by using inter- intra-basin approaches. The concludes that combination SWAT, GCMs, approaches efficiently applied assessing scale. may benefit scientists specialists.
