Figure 1 shows where the watershed is and its borders. It's about 4,560 km². Figure 2 describes the land features, like height, slope, plants, and the river system. Figure 3 points out that temperatures change a lot with the seasons, but we can't see a long-term trend from these three years. Figure 4 shows a clear seasonal pattern in rainfall, with 83 to 86 percent falling between December and March. Figure 5 shows that actual evapotranspiration matches what the plants could use during the wet season but is greatly limited by rain during the dry season. Lastly, Figure 6 shows that there's extra water during the wet season and not enough during the dry season. For example, there was about 355 mm of extra water in January 2020, and shortages often went over 50 mm per month. All these figures together show that when and how much rain falls really affects how much water is available in the Upper Ikopa watershed.</p> 2026-09-29T00:00:00Z Image Figure 10.6084/m9.figshare.34027941.v2 https://figshare.com/articles/figure/Figure_Article_GEET-2026-0060/34027941 CC BY 4.0
