Kudus city is lowland area with flat-gentle slope steepness. Usually, this area in wet season having indunation especially at city center which having high dense society. Because drainage capacity is not capable to transmited overlandflow from rainfall. The objective of the research is to account and analyse of maximum overlandflow affected by rainfall in 2,5 and 10 years return periods, and to know drainage capability for maximum overlandflow. The methode of the rsearch are analyse of rainfall frequencies based Gumbel Type 1 distribution and Pearson Type III, inlet methode, rational method, hydrograph rouitng method and slope area method. The result of the research show overlandflow in the reseacrh area affecte by similar flat of the topography conditions, few of the drainage capacity, maintenaceless of drainage, and changes of the function for waste disposal location. The darinage capacity in the research area just capable to transmite 2 years period overlandflow was dominated. Volume and time of maximum indunation on Kali Gelis G13 with 30.240 m3 overlandflow volume and 112 minute for 10 years return period.
