Spatial distribution of representative long-term annual recharge for the Silala River basin.

The overview provides an insight into how drought vulnerability is assessed and framed in forested ecoregions in cold/continental climates. By analysis of identified vulnerability factors, a conceptual framework for drought vulnerability in the study region was developed.

The Silala River at the border between Chile and Bolivia is a gravel-bed river featuring fluvial processes typical of a perennial alluvial watercourse. The entrainment and displacement length of sediments of different sizes have been studied in the field using tracers and sediment transport sampling.

Sustainable lake restoration provides an improved ecological state in the target lake, while also delivering multiple environmental and socio-economic co-benefits extending beyond the scale of intervention.

Simulation of dam break flood propagation is influenced by many parameters such as terrain resolution, mesh, boundary conditions, surface roughness and time step. The hydrodynamic model predictions of dam break will generate the flood inundation maps with flood arrival time, flood velocity and flow discharge.

In drought-prone Kitui country, Kenya, a man collects the household water from a community earth dam. Social norms suggest that only women should collect water for the household while men take care of the livestock. But exceptions happen and when men collect water—as the photo shows—there are potential consequences for community water quality alongside possible social consequences (see Bukachi et al. Water International, 2021;46(5):677–696). Photo credit: M. Korzenevica.
