  abstract = {{H}ere we investigate the changes of temperature, precipitation, river runoff and sediment transport in the {W}adi {A}bd in northwest {A}lgeria over a time series of 40 hydrological years (1970-2010). {T}emperature increased and precipitation decreased with the reduction in rainfall being relatively higher during the rainy season. {A} shift towards an earlier onset of first rains during summer was also found with cascading effects on hydrology (hydrological regimes, vegetation, etc.) and thus on erosion and sediment yield. {D}uring the 1980s, the flow regime shifted from perennial to intermittent with an amplification of the variations of discharge and a modification of the sediment regime with higher and more irregular suspended particulate flux. {S}ediment flux was shown to almost double every decade from the 1970s to the 2000s. {T}he sediment regime shifted from two equivalent seasons of sediment yield (spring and fall) to a single major season regime. {I}n the 2000s, autumn produced over 4 times more sediment than spring. {T}he enhanced scatter of the {C}-{Q} pairs denotes an increase of hysteresis phenomena in the {W}adi {A}bd that is probably related to the change in the hydrologic regime. {A}t the end of the period, due to irregularity of the discharge, the ability of a rating curve to derive suspended sediment concentration from river discharge was poor.},
