Improved Drought Management by Setting up Restriction on Consumption: Multimodal Stream Flow Forecasting
, M.Sc. Thesis Sharif University of Technology ; Abrishamchi, Ahmad (Supervisor)
Abstract
The Droughts in various parts of the world cause a lot of economic and social damage every year. In fact, droughts are due to climate fluctuations that are inherent in the natural processes of meteorological and hydrological processes and reduce water resources; population growth; Of course population growth, exacerbates its consequences. Research as well as observations have shown that climate change also exacerbates extreme phenomena such as drought and flood. The population of Kabul city, the capital of Afghanistan, is increasing due to migration from other cities, and on the other hand, the flow of the river in the summer is minimized, which for some years leads to drought. In these...

Abstract
Monthly mean satellite derived Chl-a, aerosols, wind, SST, PAR, and turbidity datasets were used to investigate the possible factors regulating phytoplankton variability in the Persian Gulf. The spatial correlation analysis revealed two distinct regions of SST and PAR, and a relatively uniform spatial correlation pattern of the other parameters. The cross correlation between aeolian dusts and Chl-a was significantly positive with 1–3 months offset. The pattern of spatial correlation between Chl-a and SST was positive in the shallow regions without time lag, and was negative with time offset of 3–5 months in deeper regions. The cross correlation between Chl-a and north-ward winds were...
