ABSTRACT Frequency analysis of rainfall involves selecting a probabilistic model to represent sample data and perform design estimates. Various probability distributions are available for this purpose, but there is no general consensus on the most appropriate one. In Brazil, such as Log-Normal, Gumbel, Generalized Extreme Value (GEV) commonly used, while less conventional models like Kappa (KAP) Wakeby (WAK) require further investigation. This study provides comparative evaluation GEV, KAP,...
AbstractThe effects of cycle time (CT) (8, 12 and 16 h) C/N ratio (3, 6 9) on nitrogen removal efficiencies in a bench top sequencing batch reactor treating slaughterhouse wastewater were investigated under different operating conditions: condition I, the reaction comprises an aerobic/anoxic phase II, anoxic I/aerobic/anoxic II phases (with pre-denitrification).

Abstract The design and management of various hydraulic structures (such as stormwater drains, bridges dams) require the estimation rainfall with duration a few minutes up to 24 h or more. Intensity-duration-frequency (IDF) curves links probability occurrence given intensity. procedure for obtaining IDF basically involves two steps: (i) frequency analysis different durations (ii) modeling curves. In first step, this study aimed adequately select upper tail weight following distributions:...
