We assessed the effects of different modes of operating reservoir on its ability to moderate water shortage impacts caused by climate change. The operating rule approach was enhanced by hedging using multiple zones and monthly rationing ratios for curtailment of water release. The results showed that basic hedging with single zone and constant rationing ratio caused significant reduction in water shortage during severe droughts. More complex operation modes produced only modest improvement.

The aim of this study is to understand the impact of flow regulation on supporting ecosystem services in the Beas Basin in India, using macroinvertebrates as an indicator. Findings show that both river flows and macroinvertebrate abundance have decreased overtime in the Beas Basin. Consequently, this could have a detrimental impact on instream supporting ecosystem services delivery. Such an understanding is important in future water resources management in the Beas River Basin.

This paper investigated the long-term trends in precipitation from 16 stations located in the lower Shire catchment in Malawi over the period 1953–2010. The results indicate that annual precipitation has increased, whereas, monthly precipitation revealed an upward trend in wet seasons (November to April) and a downward trend in dry seasons (May to October). The monthly peak trend analysis has shown upward trend in rainy months at all stations.
