Flood is a condition of the phenomenon of natural disasters that have a relationship withamount of damage in terms of life and material. Flood starts from an increasepopulation, climate change and land use change. Drainage capacitywhich is small and the amount of sediment in drainage causes flooding / flooding.Other problems also arise from household wastewater. Urban areas that aresolids cannot treat waste water individually. So, waste water willflow in urban drainage systems.
In this study, rain plays an important role in the evaluation and planning of drainageurban area. Data needed for rainfall data, land use data and datatopography. The rainfall data used is the maximum daily rainfall datareward station with a comparison of other stations. Rainfall data is analyzedwith the Log Person III and Gumbel methods then tested by Chi Square forchoose the distribution of statistics received. Rainfall data is then applied inthe intensity of rainy days with the mononobe method. Rain intensity is useful forcalculate peak discharge with a rational method.Based on the data, flooding in several channels in Tegal Barat was like on the roadPineapple, Rambutan Road, Lumba Lumba Road, Cinde and Bawal Road.
The evaluation is in the form of analyzing the discharge of each drainage channel atall of Tegal Barat region. After evaluation there are several channelsdrainage that needs re-planning such as the channels of pineapple and western baroque, cinde and dolphin channels; andsome drainage channels need normalization like the Bawal canal. |
