2 Discharge Fluctuation Effect on Meandering River Bed Evolution Kuntjoro 1 1 Civil Infrastructure Engineering Department, Vocational Faculty of Institut Teknologi Sepuluh Nopember Surabaya kuntjoro_rivers@yahoo.co.id Ismail Saud 2, Didik Harijanto 2 2 Civil Infrastructure Engineering Department, Vocational Faculty of Institut Teknologi Sepuluh Nopember Surabaya Abstract. This research was based on some considerations: first discharge fluctuation argued that none rivers with constant discharge and second meandering river bed evolution with considering that none of rivers in a steady state without bed change. This research developed to get formulation the relationship between fluctuations discharge with the evolution of the bottom of river considering discharge, parameter rivers and parameter sediment. In the span of daily discharge data and cross section monitoring annual results evolution of bottom of a river subjects obtained: Formula 1 is the relationship between discharge fluctuations with rate of sedimentation (S) and Formula 2 is the relationship between discharge fluctuations with rate of erosion (E). Thus formula have higher prediction accuracy than other published formulas and it is applicable to predict Brantas River bed evolution approximate with the real conditions. Further analysis from the output KUN-QArSHOV formula produces: Erosion equation S = 25,167e,34 Q, on constant discharge, sedimentation value occur is meter. Sedimentation equation E = 8,3455e,75 Q, on constant discharge, erosion value occure is meter. Critical point between sedimentation and erosion happened on discharge between 269 m 3 /second and 27 m 3 /second No constant discharge in the real river conditions. In the notes of discharge rivers resulting from automatic water level a recorder (AWLR), river discharge is always changing. It means there are always fluctuations in discharge in all the time. Erosion and sedimentation in the river depend on the discharge in the river. Thus discharge fluctuations will have an influence to the formation and change the bottom of a river. In general, arch is undesirable in open channels, because they friction would increase loss and lead to danger due to levee of the river by erosion and sliding caused helical flow [1],[2]. In erodible channels, the action of helical flow will develop a configuration in the bed [4]. In an alluvial bend it seems that the configuration of the channel cross section is defined more or less in accordance with certain natural laws [18], [19]. The form of bottom in arch river cross section deeper approaching cliff beyond according to Ripley and V.T. Chow [4]. The river bottom evolution in this research was 1 To whom any correspondence should be addressed. Content from this work may be used under the terms of the Creative Commons Attribution 3. licence.

3 erosion and sedimentation quantities analysed based on the discharge quantity Q that happen all the time. Thus obtained change of bottom vertical ( V) and horizontal ( H) in any change of discharge ( Q). The form of bottom in arch river cross section were deeper approached by cliff beyond according to Ripley and V.T. Chow expressed in Figure 1[4] 2 x xk y = 6,35D,437, T r o (1) Where: y = river depth (feet) x = abscise (feet) D = hydraulic depth (feet) r o = outer arc radius (feet) K = 17,52 (Chow, 1959) r o T/2 O T/2 x Arch centre 1,44 y Figure 1. The form of river cross section in arch condition Meandering River Evolution Meander evolution depends on initial geometric condition and upstream meanders that was reviewed. Thus can be estimated the movement of meanders evolution direction [4], some possible direction of meander evolution as shown in Figure 2. [6],[7],[9] Type A describe evolution meanders with low amplitude with the rate of evolution of sluggish. Type B is meander evolution that occurs along flood plains in the narrow flow of river. Type C is meander evolution that occurs in unstable levee of the river. Type D is occurs on highly meandering stream, when the meandering bend becomes too large, secondary meanders were created along the existing loop. Type E is quite similar to Mode D, but cut off is expected in this type. Type F and G were occured along locally braided sinuous or meandering stream. [8],[1] 2

Predicting Scouring and Sedimentation in Meandering River River meandering geometry changes is a natural process [12], for long time will change the river geometry [13]. Erosion and Sedimentation in Meandering River position are illustrated in Figure 3. then predicted by KUN-QArSHOV equation [14], [15], [16]. Erosion in toe of bank of the river cause sliding and other process in the river [17], these can be harmful to the river bank and hydraulic structure near closely with the river. θ = = φ Sedimentation < θ < φ Erosion Water Level Balance Condition River Width Figure 3.
