Geomorphologic evolution of the shallow-buried abandoned Yellow River delta during the last 2000 years Open
Different from the continuous development of many river deltas since the major Holocene transgression, the modern Yellow River delta (YRD) remained for nearly 1000 years (from 893 AD to 1855 AD) in an abandonment state, until after 1855 AD…

Technical note: Evaporating water is different from bulk soil water in <i>δ</i> <sup>2</sup> H and <i>δ</i> <sup>18</sup> O and has implications for evaporation calculation Open
Soil evaporation is a key process in the water cycle and can be conveniently quantified using δ2H and δ18O in bulk surface soil water (BW). However, recent research shows that soil water in larger pores evaporates first and differs from wa…
