The Topo River basin, located in the tropical region of Ecuador, is considered a little-known and well-preserved basin, with limited access conditions and scarce data that hinder its hydrological understanding. However, this gap can be addressed through this study, which evaluates morphometric and hydrometeorological factors, relating them to water storage in the Topo River basin and comparing these results with other watersheds. The aim is to identify the morphometric and hydrometeorological factors that control the variability in water storage. Firstly, a morphometric characterization was conducted. Then, a hydrometeorological characterization was carried out based on climatic data from a single station with less than two years of data, along with the calculation of the water balance. Finally, water storage in the Topo basin was compared with the main morphometric and hydrometeorological characteristics of other basins. The results showed that the Topo River basin stores 9.1 mm annually (0.20% of its precipitation), and this storage is the result of its high runoff coefficient. It was concluded that basins with lower precipitation, higher evapotranspiration ranges, larger areas, gentler slopes, smaller altitude ranges, longer rivers, and basins that are narrow and oval-shaped may have higher water storage capacity.
