“…Pakistan is a flood-prone country with historical records of various magnitudes of flood events [37,53,54]. In the past decade, flood disasters in Pakistan have surpassed all other disasters in terms of the frequency of occurrences, and also killed over 5700 people coupled with severe damages to the country's economy [5,12,15,17].…”

In flood-prone areas, the delineation of the spatial pattern of historical flood extents, damage assessment, and flood durations allow planners to anticipate potential threats from floods and to formulate strategies to mitigate or abate these events. The Chenab plain in the Punjab region of Pakistan is particularly prone to flooding but is understudied. It experienced its worst riverine flood in recorded history in September 2014. The present study applies Remote Sensing (RS) and Geographical Information System (GIS) techniques to estimate the riverine flood extent and duration and assess the resulting damage using Landsat-8 data. The Landsat-8 images were acquired for the pre-flooding, co-flooding, and post-flooding periods for the comprehensive analysis and delineation of flood extent, damage assessment, and duration. We used supervised classification to determine land use/cover changes, and the satellite-derived modified normalized difference water index (MNDWI) to detect flooded areas and duration. The analysis permitted us to calculate flood inundation, damages to built-up areas, and agriculture, as well as the flood duration and recession. The results also reveal that the floodwaters remained in the study area for almost two months, which further affected cultivation and increased the financial cost. Our study provides an empirical basis for flood response assessment and rehabilitation efforts in future events. Thus, the integrated RS and GIS techniques with supporting datasets make substantial contributions to flood monitoring and damage assessment in Pakistan.

“…Monsoon season temporally extends from June to September in South Asia, but it brings more rain during July and August which results in disastrous floods [14]. Pakistan has faced flood events of various magnitude since 1950 but the catastrophic were in 1988, 1992, 2010, and 2014 [15]. The hydrometeorological conditions, geography, and lack of standard structural measures in the Indus watershed are the main factors of flood genesis [16].…”

“…The spatial extent¸ depth, duration, and direct effect of flood were variable because of the spatial diversity in relief features and landforms, human land uses, population density, and anthropogenic activities. This was the most calamitous flood in Pakistan's flood history [15]. Similarly, high flood in river Chenab and Jhelum has been observed in September 2014 in which Chenab has attained peak of 0.45 million m 3 /s [16].…”

This chapter analyzes the extent of flood damages in the Chenab basin upper Indus plain. The upper Indus plain is a fertile area and supports millions of human population and diverse economic activities. Every year in summer, the combined action of monsoon rain water and meltwater (melting of snow and glaciers) augment rivers discharge leading to damaging flood. The study region is prone to floods. The upstream areas of Chenab basin are mountainous and experiences characteristics of flash floods, whereas riverine floods dominate the lower reach. In wake of observed climate change, there is a rising trend in temperature, which indicates the early and rapid melting of snow and glaciers in the catchment areas. The analysis reveals that the spatial and temporal scales of violent weather events have also been grown during the past three decades. The substantial increase in heavy precipitation events and rapid melting of snow in the headwater region, siltation in river channels, human encroachments on the active flood plain and bursting of embankments have further escalated the flooding events. Analysis further reveals that in the study region, almost every year, the floodwater overflows the levees and cause damages to standing crops, infrastructure and sources of livelihood, and incurs human casualties.
