Assessment of climate change impact on water diversion strategies of Melamchi Water Supply Project in Nepal

Bias correction of climate models for hydrological modelling – are simple methods still useful?

“…Of the few, in Shrestha et al . (), Hadley Centre Global Environmental Model version 3 regional climate model (HadGEM3‐RA RCM) also exhibits overestimation of mean precipitation (by almost a factor of 2) at four out of six precipitation stations. An underestimation of maximum and minimum temperature by around 9 and 2 °C respectively was also observed in the same study.…”

“…Studies such as this one, with RCM estimates based on the latest representative concentration pathway scenarios under the International Panel for Climate Change Fifth Assessment Report (IPCC AR5), are rare in the Nepalese Himalayas. Of the few, in Shrestha et al (2015), Hadley Centre Global Environmental Model version 3 regional climate model (HadGEM3-RA RCM) also exhibits overestimation of mean precipitation (by almost a factor of 2) at four out of six precipitation stations. An underestimation of maximum and minimum temperature by around 9 and 2 ∘ C respectively was also observed in the same study.…”

Bottom-up quantification of inter-basin water transfer vulnerability to climate change

“…Maknoon et al (2012) used Dez to Qomrood Inter-Basin Water Transmission Project in Iran as a case study and evaluated the efficiency of different protocols under the effect of climate change. Shrestha et al (2015) analyzed the impact of climate change on the water diversion plan for the Melamchi Water Supply Project (MWSP) in Nepal. However, the existing studies were all based on the top-down framework mentioned above, i.e.…”

Assessment of Climate Change Impact on Water Diversion from the Bago River to the Moeyingyi Wetland, Myanmar

“…Although climate change is a global phenomenon, the impact is mostly faced by regional communities 8 . It is of utmost importance to assess the impact of climate change on hydrology at regional scale to better understand the potential change in water resources 6,[8][9][10][11] . Previous studies in many Asian countries have concluded that climate change will negatively impact water resources 8,9,12,13 .…”

“…The impact of climate change on river run-off was projected using three general circulation models (GCMs) and two emission scenarios for different future periods. Multiple GCMs were used in the study to reduce the uncertainty while projecting the climate change impact analysis, which has been widely adopted in other studies 8,11,13,15,16 . The result of this study would provide a change in the discharge of the Bago River due to climate change for diversion to the Moeyingyi wetland.…”
