Sentences with phrase «hydrological changes in the region»

Although the recent drought may have significant contributions from natural variability, it is notable that hydrological changes in the region over the last 50 years can not be fully explained by natural variability, and instead show the signature of anthropogenic climate change.

That's a growing problem, because in many places, finding water for energy isn't easy - and it's bound to get tougher as energy demands soar and climate change alters hydrological cycles in already arid regions.

This study investigates a physical basis for heterogeneity in hydrological changes, which suggests a greater detectability in wet than dry regions.

Although these hydrological changes could potentially increase soil water availability in previously snow - covered regions during the cool low - ET season (34), this effect would likely be outweighed by the influence of warming temperatures (and decreased runoff) during the warm high - ET season (36, 38), as well as by the increasing occurrence of consecutive years with low precipitation and high temperature (Fig. 4A).

As noted in the TAR (McAvaney et al., 2001), vegetation change during the mid-Holocene likely triggered changes in the hydrological cycle, explaining the wet conditions that prevailed in the Sahel region that were further enhanced by ocean feedbacks (Ganopolski et al., 1998; Braconnot et al., 1999), although soil moisture may have counteracted some of these feedbacks (Levis et al., 2004).

PTI: Studies conducted by Geological Survey of India indicate some of the likely impacts of melting of glaciers on the hydrological system in form of changes in the river hydrology, increased debris production and siltation of rivers in downstream region.
