the present research focuses on the changes of urmia lake level. for this purpose, two timescales have been considered. the trend changes of temperature, precipitation rate and quantitative values of climate type for the observational period from 1968 to 2011 (past scale) and from 2011 to 2100 (future scale) have been analyzed. general circulation model (gcm) is considered for simulating the va...

Abstract Understanding water level (WL) fluctuations in river deltas is of importance for managing resources and minimizing the impacts floods droughts. Here, we demonstrate competing effects atmospheric oceanic forcing on multi-timescale variability changes Pearl River Delta (PRD) WLs southern China, using 52 years (1961–2012) in-situ observations at 13 hydrological stations. PRD WL presents s...
