Flood frequency Studies

(BQ) Ebook Engineering hydrology (Third edition): Part 1 is presented in four chapters. The characteristics of flood hydrographs and the unit hydrograph theory together with an introduction to instantaneous unit hydrograph are covered insufficient detail with numerous worked examples in Chap. 6. Floods, a topic of considerable importance, constitute the subject matter of Chap. 7 and 8. While in Chap. 7 the flood-peak estimation and frequency studies are described in detail, Chap. 8 deals with the aspects of flood routing, flood control and forecasting.

In Odisha the Mahanadi is the largest river with an extensive delta responsible for most of the devastating flood hazards in the coastal zone. Over a period of 146 years between 1855 and 2000 there were 28 high flood years, 57 medium flood years and 48 low flood years (Mishra, 2008). There is a need to study the peak flood magnitude at different probability of exceedences by different probability distribution functions.

In flood-prone cities such as Manila, potential sea level rise and increased frequency and inten- sity of extreme weather events poses enormous challenges on urban local bodies’ ability to adapt. Apart from their location, the scale of risk is also influenced by the quality of housing and infra- structure, institutional capacity with respect to emergency services, and the city’s preparedness to respond.

In recent years, under impacts of human activities and climate change, flood has been increased in both the frequency and magnitude, causing lots of damages to people. This study presents a method to evaluate the direct spatial damages of flooding based on inundation depth and land use data. Damage functions for different types of land use arc selected and applied. Matlab strings and GIS are combined to calculate damage in monitery term. The method is applied for estimating loss caused by thc flood event November 1999 for Huong rivce basin.
