Content Introduction Precipitation Applications The Hydrologic Cycle Conclusion References

Introduction Engineering or applied hydrology – a study concerned with engineering application like design dam, our project given realistic case study (og catchment) in west bank. In our project we want to calculate the peak flow that produced from the excess rainfall at the area that we want to design the Dam.

Applications  Determining the water balance of a region.  Determining the agricultural water balance.  Designing riparian restoration projects.  Mitigating and predicting flood, landslide and drought risk.  Real-time flood forecasting and flood warning.  Designing irrigation schemes and managing agricultural productivity.  Part of the hazard module in catastrophe modeling.  Providing drinking water.  Designing dams for water supply or hydroelectric power generation.  Designing bridges.  Designing sewers and urban drainage system.

Precipitation Single strongest variable driving hydrologic processes Formed by water vapor in the atmosphere As air cools its ability to ‘hold’ water decreases and some turns to liquid or ice (snow)

Causes of Precipitation

Weather (day to day) vs. climate (years-decades and patterns) What are hydrologists most concerned with? Climate and geography result in biome classification Weather vs. Climate Patterns

Plant Transpiration Most water absorption occurs in upper half of root zone

Conclusion The Hydrologic Cycle is constantly happening all around us each and every day and is an essential part of life. It is necessary so that we have shade from clouds, to water our plants with the falling rain, and for fish to swim in. I hope you found this unit interesting and enjoyable, and appreciate water even more! To learn more about water and the Hydrologic Cycle refer to the links on the websites given, look in your school library, or ask your teacher to direct you to other resources.
