Non-linear hydrologic organization

Abstract. We revisit three variants of the well-known Stommel diagrams that have been used to summarize knowledge characteristic scales in time and space some important hydrologic phenomena modified these focusing on spatiotemporal scaling analyses underlying processes. In present paper we focus soil formation, vegetation growth, drainage network organization. use existing relationships for growth both which refer same fundamental length timescales defining flow rates at pore scale but different powers power law relating space. The principle a hierarchical organization optimal subsurface paths could underlie root lateral spread (RLS) basin To assess applicability scaling, extend diagrams, data depth, spread, accessed. new considered here include out 150 Myr correspond depths up 240 m horizontal 6400 km probe limits development time, extent.
