Drought in intermittent river and ephemeral stream networks

Intermittent rivers and ephemeral streams (IRES), those watercourses that periodically cease to flow or dry, are the world's most widespread type of river ecosystem. Our understanding natural hydrology ecology IRES has greatly improved, but their responses extreme events such as drought remain a research frontier. In this review, we present state art, knowledge gaps directions on droughts in from an ecohydrological perspective. We clarify definition IRES, giving recommendations promote transferability how studies characterize non-perennial stream networks. Based systematic search literature, also identify common patterns sources variation ecological provide roadmap for further enable improved management during hydrological events. Confusion terminology lack tools assess may have hindered development IRES. found 44% confused term with seasonal drying measure transferable way minority. Studies networks still rare limited few climatic zones organisms mainly explored perennial sections. review highlights need additional topic inform conservation.
