Main Article Content
Abstract
Aggradation of the urban drainage channels caused by sediment transport discharge from upstream Sq, sheet erosion from catchment area Se, and decomposition of domestic solid wastes entering to the channel Sd. Formulation for the aggradation is S = Sq + Se + Sd. Each is from Engelund and Hansen, formulation of the Universal Soil Loss Equation (USLE) from Wischmeier and Smith, and Marsudiantoro and Soeryantoro. From the result, the influence of sediment transport and sheet erosion to aggradation process of channel are small (5,39% and 7,45%), while the most part of aggradation came from solid waste's decomposition (87,16%).
