Soil moisture plays an important role for understanding hydrology and climate. Soil moisture is a key variable in hydrological process, as the availability of moisture content in soil controls the mechanism between the land surface and atmospheric processes. Accurate estimation of soil moisture is crucial in environmental studies. Soil moisture can...

Pakistan experienced a devastating flood which originated on 22th July, 2010 from Khyber-Pukhtunkhwa and Punjab. In order to monitor the daily extent of the inundated area due to flooding medium resolution MODIS data has been used. The frequent availability and good temporal resolution MODIS data has been very effective for obtaining the first hand...

TRMM satellite is a joint venture project of JAXA, Japan and NASA, USA. It has been launched for assessment of rainfall in global and regional perspective. The objectives of this paper include validation of TRMM satellite data for Pakistan. In this paper a detailed comparison of 07 years TRMM based precipitation data (product 3B43 V6 0.25 o o X 0.2...

1. ABSTRACT Flooding is the inundation of land with unwanted water causing damages to lives and livelihood. Flooding can be triggered by heavy rain fall accumulation, due to cyclones that may generate intense rains, due to tides at coastal areas, due to melting of glaciers or stream blockage in nearby areas. Floods can hit the region's economy badl...

... Soil moisture is highly variable in time and space due to heterogeneity of soil properties, topography, land cover and the non-uniformity of rainfall events and evapotranspiration rates at various spatial scales (Crow et al., 2012;Umar et al., 2016;Santos et al., 2014). Time domain reflectometry (TDR) or gravimetric sampling techniques can provide quantitatively accurate point based field measurements of soil moisture but they cannot consider changes in spatial distribution across gradients of soil surface characteristics (Lakhankar et al., 2009). ...
... • The pre and post flood image of PALSAR had been downloaded and region of interest (ROI) were drawn using ENVI software along the path of Indus River to distinguish flooding in the river. • The PALSAR images used were geo-rectified using ENVI-software Another case study was carried out for mapping inundated areas in Mardan city in NWFP Province of Pakistan that was hit by intense heavy rains during month of August, 2006 [4]. For the study it was thought to use PRISM DEM for analysis of low laying areas and pan sharpened PRISM + AVNIR images for land cover study. ...
... The other betterperforming model was IPSL_CM-4.1 (mean 11%), but with a higher standard deviation (32.7%). Earlier studies have shown that the TRMM data match well with the station data in the region (Rahman and Sengupta, 2007;Jilani et al., 2008), which gave us confidence to replace the WM data with the TRMM data for further analysis. ...
... Similar work was done for another flood study that hit the north region of country, during February 2010. The floods or inundation in villages near by affected area had occurred due to land slide that blocked the flow of glaciated fed river Hunza, causing upstream villages under water [5]. Methodology followed was as is given below: @BULLET Houses and crop fields were annotated with the help of google-earth (the only source of high resolution imagery). ...
