“…The Indus originates in the high Himalayan mountains of China, India and Pakistan in the north and extends to the dry alluvial plains of Sindh Province in Pakistan in the south, finally draining into the Arabian Sea (Ali & De Boer, 2007;FAO, Aquastat, 2011a). The major part of the basin lies in arid-to-semi-arid climatic zones, but there is considerable temporal and spatial climatic variation across the area.…”

The Indus, Ganges and Brahmaputra river basins support 700 million people in Asia. The water resources are used for irrigation, drinking, industry, navigation and hydropower. This paper reviews the literature on the impact of climate change on the hydrological regime of these river basins and suggests that the different basins are likely to be affected in different ways. Climate change will have a marked affect on meltwater in the Indus Basin and may result in increased flood risk in the Brahmaputra Basin. The overall impact on annual discharge is likely to be low, but more studies are required to understand intra-annual changes and the impact of extreme events.

“…Exceptional damage was inflicted on crops and cropland, and on agricultural support systems, such as canals and levees; 4.5 million people, mainly agricultural workers, lost their employment for the period 2010À2011 (Khan et al 2011). Human interventions through the construction of embankments, barrages, dams, land clearance and land-use change, etc., have also disturbed the river system in terms of sediment load and their runoff, leading to more severe floods (Ali & De Boer 2007;Gaurav et al 2011).…”

“…The upper and lower parts of the Indus River experience very diverse rainfall patterns and weather conditions. The northern part of the Indus Basin is mainly characterized by high mountains and glaciers, and cold-arid climatic conditions, whereas the lower part experiences subtropical to tropical climate as it reaches the Arabian Sea (Ali & De Boer 2007). Much of the flow of the Indus River originates from either glacier melt or monsoon rainfall.…”

“…Summer monsoon and western disturbance in late winter and early spring are responsible for high precipitation in the Indus Basin. The basin receives the highest rainfall during the monsoon season (JulyÀSeptember), and this often causes major flooding in Pakistan (Ali & De Boer 2007;Inam et al 2007). The average annual precipitation of the Indus region varies from 125 mm over the lower plains to about 500 mm in the upstream in Lahore (Khan et al 2011;Inam et al 2007).…”

The paper presents a moderate resolution imaging spectroradiometer (MODIS) time-series imagery-based algorithm for detection and mapping of seasonal and annual changes in flood extent, and tests this using the flooding of the Indus River Basin in 2010 À one of the greatest recent disasters that affected more than 25 million people in Pakistan. The algorithm was applied to produce inundation maps for 10 annual flood seasons over the period from 2000 to 2011. The MODIS flood products were validated in comparison with advanced land observing system (ALOS) sensors, which have both advanced visible and near infrared radiometer and phased array type L-band synthetic images using the flood fraction comparison method. A simple threshold method is created to cluster the data to identify the flood pixels in the imagery. Calculations are then made to estimate a flood area for each resolution. A statistical study is performed to analyze false positive and false negative rates using the ALOS sensors as 'ground truth'. Comparison of two flood products at a grid size of 10 km resulted in the coefficient of determination range of 0.72À0.97. This research points to a relevant spatial resolution that could be effectively used to obtain accurate mapped products of the extent of the inundated area. The approach can be used to quantify the damage caused by floods.

“…Ali and De Boer 2) found that the main sediment sources in the Indus valley includes channel erosion, gully erosion, and steep hill-slope erosion due to the combination of continuing tectonic instability, glaciers melting and heavy monsoon rains. It is the need of hour to practice river basin management techniques to reduce sediment yield.…”

Sedimentation aspects have a major role during the design of new reservoir projects because life of the reservoir mainly depends upon sediment handling during reservoir operation. Therefore, proper sediment management strategies should be adopted to enhance the life span of reservoirs. Basha Reservoir is one of the mega water resources projects which are being planned to construct on the Indus river. Under this study, the efficiency of four sediment management strategies were evaluated by using the RESSASS model. The reservoir management strategies considered for sediment simulation of Basha reservoir include the normal operation, raising of MoL, draw-down the MoL (flushing) and controlling the sediment inflows. Under normal operation, the model predicted the life span of Basha reservoir around 55 -60 years. But by raising of Mol 2.0 m/year implemented after 35 years of operation may add 10 -15 years more to the life-span of the reservoir. However, by adopting the flushing operation to draw-down the MoL at El. 1010 m initiated after 35 years of operation, it may also add about 15 -20 years more. Moreover, the results obtained by considering 50% reduction in sediment inflow due to implementation of river basin management projects upstream of Basha within 30 years of reservoir operation, depicts that the life of the reservoir will be more than 100 years. It is therefore concluded that proper sediment mitigation measure can significantly enhance the life-span of planned reservoirs.
