what sea is located south of the indus river valley?
the arabian sea
the indus river feeds the indus submarine fan, which is the second largest sediment body on the earth. it consists of around 5 million cubic kilometres of material eroded from the mountains. studies of the sediment in the modern river indicate that the karakoram mountains in northern pakistan and india are the single most important source of material, with the himalayas providing the next largest contribution, mostly via the large rivers of the punjab (jhelum, ravi, chenab, beas and sutlej). analysis of sediments from the arabian sea has demonstrated that prior to five million years ago the indus was not connected to these punjab rivers which instead flowed east into the ganga and were captured after that time. earlier work showed that sand and silt from western tibet was reaching the arabian sea by 45 million years ago, implying the existence of an ancient indus river by that time. the delta of this proto-indus river has subsequently been found in the katawaz basin, on the afghan-pakistan border.
indus river
lbod is located in the catchment area of the old nara river which is a left bank delta channel of indus river. old nara river streams are used to collect the saline water generated from irrigated lands and the industrial effluents. in the middle reach (i.e nara canal) of this river, saline and polluted water flowing into the river are diluted by feeding main indus river water from sukkur barrage and supplied by gravity canals for irrigation and industrial needs. the saline water generated from the irrigated lands and the industrial effluents are collected by the lbod canal network from the lower reaches of the old nara river or puran river to discharge by gravity flow to the sea. also bore wells are used to pump saline water in to the lbod or the old nara river streams to depress the saline ground water level at safe depth or prevent waterlogging. as most of the cultivated lands are located on the left side of the indus river, lbod would be the predominant means of discharging the river salt load to the sea once the indus river waters are fully put to use without letting the indus river water overflow to the sea from the kotri barrage which is the last barrage across the river. effective usage of lbod is crucial to preserve/enhance the soil fertility in lower reaches of indus basin area or sind province or indus river delta for discharging adequate salt load to the sea.
