Evolution of Hydrological Drought in Human Disturbed Areas: A Case Study in the Laohahe Catchment, Northern China

Figure 5

Variations of annual precipitation, runoff, runoff coefficient, baseflow, and baseflow index (BFI) over the Laohahe catchment since 1964. The red dashed line represents linear trend for hydrological variables (precipitation, runoff, and baseflow) and the blue dashed line for runoff coefficient and BFI.
