CRITICALREVIEW: I am writing an reviewarticle on the subject of “Techniquesof Remote Sensing and GIS for flood monitoring and damage assessment: A casestudy of Sindh province, Pakistan “, written by the Mateeul Haq,Memon Akhtar, Sher Muhammad, Siddiqi Paras and Jillani Rehmatullah.
The topicof the journal does not suits as it may not includes any software and justrequires the MODIS images. The abstract is not covering the methodology section.The topic of the journal is of great importance that is Flood damageassessment, it causes a lot of problems associated with rehabilitation, foodinsecurity due to crop failure. The material of the data is enough to tellabout the complete story of the assessment process.Introduction: Duringthe monsoon period, a natural disaster known as flood is causing too muchdestruction for the entire country since 1928. The journal includes the yearsof the main damages that occur due to flood. The Indus River claimed more than7000 population, and 7.7 million acres of land that was affected due to theflood.
The focused flood starts from the august and ends in September, causingthe inundation canals to be over flow. The flood causes economic loss, foodrelated issued and starving population. Now we can use GIS and RS to evaluatethe destruction of the flood.
The rapid evaluation may assists us to solve allthe problems related to flood.The journal covers thearea of 140915 km2 of Sindh province that receives thesouthern monsoon and retreating monsoon. The maps are used having distinctboundaries that elaborates the boundaries of lakes, rivers, mountains, roadsand railway tracks etc. The main myth of the reviewing the article is to findthe rapid evaluation for flood management and to assess the damages. There aremany terms like MODIS is not understandable for the common reader so it must beclear. Only abbreviation is not enough.
The Usage of ArcGIC and RS is not thateasy, so journal demands a man too who have expertise in these softwares. Themost of the problems in cities of Sindh province show variation in the tabularform to compare the results for the damage.Methodology:The images areprocessed by the NASA and the satelliteimages are intersected with the shape file to form classification, flooded areaextraction, and to find the affected area, affected agriculture, affected roadsand affected forests that causes loss in biodiversity. Discussionand results: Thereare details of damages associated with the different parameters. The area is a majorconcern here.
Badin have 3820.39 km2damaged area, whereas Mirpurkhas has an areaof 1836.26 km2 Jacobabad covered damaged area of 1352.32 km2 Shahdadkot was damagedby the area of 1597.50 km2 Dadu by 1887.57 km2 and Sanghar with an area of 2494.
18 km2overall. There were damages to 5.88 million people, 5329 settlements and alarge network of the roads were also affected. At the end only a few referencesare given that are insufficient for the proper knowledge.The work reported wascarried out for the National Disaster Management Authority, Pakistan and SindhIrrigation Department, Pakistan.
