Waibakul City, Central Sumba Regency, East Nusa Tenggara Province, Indonesia is affected by floods every year that comes from overflow of drainage channels. The area of Waibakul is 76, 44 km^2 and dominated by agricultural land. The drainage system is incorporated into the irrigation system, thus forming a complex network of channels. The topography of the area is very flat, with slope (0 to 3) % reaching 78.56% and forming natural basins that are used as rainwater catchment reservoirs. The results of evaluation show that the majority of channel capacity is not roportional to the burden that must be discharged. The reservoir performance is not maximal because the water discharge system only relies on natural water absorption into the soil, so if there is a successive rain then the reservoir is full thus the reservoir control capacity becomes very small. The recommendation for flood control strategies are: (1). Divide the catchment area into sub-catchment areas based on the drainage service area, so the problems can be more easily solved and completed gradually. (2). Increase the capacity of multiple channels. (3). infiltration wells as a means of reservoir water drainage.(4). Control the burden of flood discharge to the office area by making a shotcut. (5). Control the flood water level in rivers that is crossing central office area by making long storage with spillway. 1. Introduction The urban area of Waibakul Regency of Central Sumba, East Nusa Tenggara Province, Indonesia lies in the valley and mostly (78.56%) has a very flat topography slope (0-3)% [1] Waibakul urban area is 76,44 km2[2] and dominated by productive rice fields that become the mainstay to meet food needs. In some locations, natural hollows are formed that accommodate surface runoff water. Waibakul city drainage system is integrated with its rice field irrigation system, and forms a fairly complex network of channels. Routine floods occur annually in several locations, including central office areas. Flooded puddle is [1] lower agricultural productivity, and disrupt economic activity and service to citizens. Flat topography and dual function demands on the channel, conditioning the water level elevation on the drain must be maintained so that when functioning as a water irrigation it can flow into the gravity field. [5] This affects the velocity of the water in the channel becomes very low, and the discharge capacity becomes very small. It causes great sedimentation and channel function as the discharge system becomes [5] not maximal. The flood prevention efforts are carried out by utilizing several natural basins as reservoirs [6] of flood waters and improving the condition of some channels. However, the results obtained have not been significant, since the improvement plan has not been based on appropriate strategies and sufficient [22] technical analysis. In this study, the flood control strategy is prepared with a conservation orientation and does not use modern buildings or tools.

Concept Development In efforts to control flood in urban areas is doing an approach which is combination of channel capacity improvement with existing structural optimization efforts to restore natural flow patterns before urbanization [3]. The approach in flood solving in Waibakul urban area is oriented towards: simplification of problems, improvement of flood channeling system performance, and decrease of flood discharge peak. [6] The simplification of the complexity of the channel network system and the extent of the Water Catchment Area (DTA) is solved by dividing the DTA into several Sub-catchments (Sub DTA). The channel network [41] system is also parsed and grouped into each DTA.
