Precipitation Precipitation is any form of solid or liquid water that falls from the atmosphere to the Earth’s surface.Forms of precipitation : – Drizzle: water droplets, low intensity, 0.1 – 0.5 mm – Rain: water droplets, higher intensity, > 0.5 mm – Glaze: ice coatings formed by freezing rain – Sleet: ice grains formed … Read more
INTRODUCTION ‘Hydrology’ is derived from two words: ‘hydro’ and ‘logos’. ‘Hydro’ means water, and ‘logos’ means study. Simply, hydrology is defined as the study of water. Hydrology is the science which deals with the origin, distribution and circulation of water in different forms in land phases and the atmosphere.A broad definition of Hydrology given by … Read more
