A dual box system, consisting of a 2 m long feeder box and a 5 m long test box with 150 gradient was used to quantify effects of run on water and sediment on rill erosion process at down slope section and rill flow hydraulics parameters, as well as relationship of rill flow hydraulics parameters and sediment delivery by rill erosion.

Effects of runoff from upslope on rainfall infiltration and soil water redistribution at a planar slope;

Response of the bank-full discharge to runoff and sediment load in the Lower Weihe River;

Based on two phases(1987?2002)vector data about wetland in lower Yellow River basin and runoff and sediment load data,we reconstructed the former landscape structure and elucidated the changes in landscape patterns during the last 20 years,and discussed the feedback to the runoff and sediment load.

This article studies the characteristics of the water & sediment load from 1960 to 1997 and the longitudinal & transversal bed profile from 1977 to 2002 by employing statistic analysis.

There are different sources for water flow and sediment in the upper Yellow River with uneven distribution of water and sediment inflows.

There are main factors effecting on elevation in Tongguan reach, such as the conditions of incoming water and sediment, the scouring and depositing condition in the upper and lower reaches and the operation water level before dam, among them, the conditions of incoming water and sediment as dominant one.
