In 2011, the summer temperatures were moderate and the rains came in small doses, judiciously spaced, after a wet winter had built up water reserves.
Super-heating occurs when water in a microwave heats water past its boiling point but the water is unable to form bubbles because there are no nucleation sites (essentially rough spots for the bubbles to form on). As soon as the water is disturbed or a nucleation site is introduced, the built-up superheated water forms steam very quickly, causing a small explosion of boiling water.[6].
The images of the study area were categorized into five different classes namely vegetation, agriculture, barren, built-up and water body.
Overall, an estimated 1m people need food aid now, and many will need it through the winter.In built-up areas, water and sanitation systems have been shattered, so some 4m people are defecating in the open, giving a high risk of an outbreak of disease.
The constraints were built-up areas, water (lakes and rivers), and areas characterized by hydrogeological instability.
Hence, the five land-cover classes are as follows: urban built-up, vegetation, water body, green spaces, and crop land were mapped.
The satellite data of IRS LISS-III were classified into five categories viz., built-up, vegetation, water body, agricultural land and others by employing unsupervised ISODATA classification technique.
A Stratified Random Sampling (SRS) technique was used to plot 299 samples (30 m × 30 m) on various LC features e.g. forest, agriculture, grassland, built-up area, water body etc. GPS readings (latitude, longitude and altitude) were recorded with digital camera photographs against each sample, which were added into a geo-database for record keeping.
Land use types were classified as follows: built-up land, water body, dry land, scrub, orchard, irrigable land, rice paddies, and forest.
Both LUC maps contained four categories, namely built-up area, vegetation, water body, and wet land.
