Late Quaternary landscape evolution in river valleys of the Nebraska sand Hills, USA
• First detailed late-Quaternary landscape evolution study of rivers in the Sand Hills. • Gradual alluvial aggradation in river valleys from ca. 12.8–8.0 ka; marshes common. • Increased aridity from 8.0 to 3.0 ka triggered landscape instability and erosion. • Episodic alluvial aggradation and landscape stability after ca. 3.0 ka. • After 1.2 ka, rivers incised and alluvial fans (7–8 m thick) rapidly aggraded.
