Flash Floods and Their Control in the Indian Arid Zoneby K. D. Sharma,
Abstract: Flash floods are common hydrologic phenomena in the arid north west India. Drainage basins of high relief, a large percentage of surficial bed rock, sparse vegetation, and shallow soils are susceptible to flash flooding when cyclonic storms and monsoon depressions produce intense and localized rainfall. Favorable antecedent moisture condition and breaches in the earthen dams worsen the flood situation. Since 1917 there have been 15 flash floods of moderate to severe intensity in the Luni Basin (34,866 km²) located within the Indian arid zone.
