Effect of Antecedent Rainfall Patterns on Rainfall-Induced Slope Failure [PDF]

open access: yesJournal of Geotechnical and Geoenvironmental Engineering, 2011
Rainfall-induced slope failure occurs in many parts of the world, especially in the tropics. Many rainfall-induced slope failures have been attributed to antecedent rainfalls. Although it has been identified as a cause of rainfall-induced slope failure, the pattern or distribution of the antecedent rainfall has not received adequate attention.

Effect of Radar-Rainfall Errors on Rainfall-Runoff Modeling [PDF]

open access: yesWorld Environmental and Water Resources Congress 2007, 2007
Recent years have witnessed significant adv ances in development of operational radar rainfall products. These products are desirable for several hydrologic applications such as flood forecasting and rainfall -runoff modeling. It is recognized that radar -rainfall estimates are associated with unkno wn uncertainties.
