Hydrologic Balance: Hydrology for Engineers

This lecture introduces the science of hydrology, covering the occurrence, circulation, and distribution of Earth's waters, as well as their chemical properties. It explores the role of hydrology in engineering, focusing on floods, droughts, and water distribution. The lecture delves into the challenges of water scarcity, emphasizing the global issues of access to safe drinking water and sanitation. It also discusses the hydrologic cycle, quantifying the global water balance. Control volumes and the continuity equation are explained, highlighting their importance in understanding mass flux. Various scales in hydrology, from local to global, are examined, emphasizing the spatial and temporal aspects of water processes.
