The model involves the continual circulation of water between the oceans, the atmosphere, vegetation and land. Hydrologic Cycle The field of science that is concerned with the study of the occurrence, distribution and movement of water below the surface of the earth is called Groundwater Hydrology. f Hydrological Cycle is fundamental to the functioning of the Earth as it recycles water, and has a role in modifying and regulating the Earth's climate. Hydrological Cycle Water cycle, also called hydrologic cycle, cycle that involves the continuous circulation of water in the Earth-atmosphere system. Again, taking careful notes over key concepts and terms. Explore now. Most biogeochemical cycles can be described as elemental cycles involving nutrient elements such as carbon, oxygen, nitrogen, sulfur and phosphorus. ), but there are strong feed-back mechanisms between hydrological and meteorological processes. the other quantities in the hydrologic cycle. Water is constantly moving through the spheres (atmosphere, hydrosphere, biosphere, geosphere). The hydrologic cycle can be broadly divided into two phases - land phase, and atmospheric phase. Many are gaseous cycles in which the element • Hydrologic cycle and its components, • Measurements of Hydrologic cycle components: -Precipitation, Evapo-transpiration, Infiltration, Runoff • Types and forms of precipitation. Figure 1.1 shows a schematic flow chart of the hydrologic cycle. Simply, Hydrology is defined as the study of water. Precipitation on Land 1 Surface Runoff Infiltration Subsurface Flow Evaporation from Land Groundwater Flow Moisture over Land Surface Outflow to Oceans Groundwater Outflow to Oceans Evaporation from Ocean Precipitation on Ocean.6.4 4.2 3.9.4.01 Big Picture (Syllabus) Today's Objectives Hydrology . The rain water that falls on the ground surface is divided into three parts: They are: ADVERTISEMENTS: (i) One part directly returns to the air as water vapour by evaporation and transpiration from plants. 'Hydro' means water and 'logos' means study. In India, rainfall data is collected everyday at 8.30AM and if this rainfall is more than 2.5mm on a day then that day is called Rainy Day. The largest reservoir for water is the oceans, but considerable water is present in the atmosphere (as gaseous water vapor), on land (in lakes, rivers and glacial ice) and under the ground (as groundwater). This cycle is the exchange of energy which influences climate. Global water balance (volumetric) Land (148.7 km2) (29% of earth area) Ocean (361.3 km2) (71% of earth area) Precipitation 100 Evaporation 61 Surface Outflow 38 Subsurface Outflow 1 Precipitation 385 Evaporation 424 Banks are failing, money is drying up and even profitable geological ventures like oil, View HYDROLOGIC CYCLE (1).pdf from ECE 2402 at School of Law, at Jomo Kenyatta University of Agriculture and Technology. The same water that existed on the earth millions of years ago is still present today. Water is constantly moving due to the energy of the sun transforming surface water into wa對ter vapor. The Free Water Cycle PDF includes three Water Cycle Diagrams to help explain the steps of the water cycle as well as two lesson check worksheets. Water cycle also known as Hydrological cycle or Hydrolic cycle is the continuous movement of water on above or below the surface of land. The Global Hydrological Cycle might be more simply referred to as the water cycle. Snow : These are ice crystals having a density of .1gm/cc. The biggest Benefit of these notes i.e. The quantities of water going through various paths of the hydrological cycle in a given system can be described by the continuity principle known as water-budget equation or hydrologic equation.It is important to note that the total water resources of the earth is constant and the sun is the source of energy for the hydrologic cycle. Though the actual hydrologic cycle is quite complex, this figure just broadly depicts the sequence of major events of the cycle. It's like a big circle! The hydrological cycle is also known as the water cycle. During this process, water changes its state from one phase to another, but the total number of water particles remains the same. Lecture Page 34/55. Hydrological Cycle See Prosser, p.41 Waugh, p.58 fig. The Water Cycle What is the Water Cycle? The hydrological cycle is a process of constant water exchange or water circulation in the hydrosphere, i.e. The role of different processes in the hydrological cycle and their description depends on the Seas and oceans contain 97% of the world's water, and ice holds 2%. The physical and chemical properties . hydrologic cycle (contd.) The water cycle is also known as the "hydrologic cycle" Earth has been recycling water for over 4 billion years! Water is an Components of the Hydrologic Cycle - Storages and Flows • Precipitation - Includes rain, snow and other forms of water falling from the atmosphere in liquid or solid phase into the land and oceans. The water vapor eventually forms clouds, and clouds condense back into . cal cycle is theresult of a re-orientation and in part extension of the lecture notes I used during the years I was teaching the hydrology students of the Free University of Amsterdam an annual course in Isotope Hydrology. NYS Regents Earth Science Mr. Burgess Unit 12: The Hydrologic Cycle Notes Packet 6 | P a g e Soil Sandy soils can hold more water and drain faster because they have more pore space for water to flow Soils made mostly of clay hold water, but do not drain quickly Rock Type Some rocks that are permeable allow water to enter them Other liquids like oil can enter the rock as well Because 70 percent of the Earth's surface is covered by water, perhaps the Earth The hydrologic cycle describes the continuous re-circulating transport of the waters of the earth, linking atmosphere, land and oceans. Did you know? This is due to the water cycle. Hydrologic Cycle Importance of Hydrology §Hydrologic design provides a service §Level of service must be defined and acceptable risk of failure must be determined (local drainage ordinances) §Cost and site characteristics are typical constraints What is the importance of hydrologic engineering design?
