A watershed in which the observed discharge data is not available or incomplete becomes a problem in thewater utilization projects. Observation discharge data obtained from Pos Duga Air Sungai Temef is less reliable because the measurement of water level data for the last few years has been carried out by direct observation without using a discharge measuring device. Obtain river discharge data, it can be done by simulating rainfall data into discharge data, one of them is NRECA Model. In NRECA Model, there are several parameters, namely index soil moisture capacity (nominal), Percent Sub Surface (PSUB), Ground Water Flow (GWF), and crop coefficient (kc). Determination of the parameters NRECA Model was obtained by trial and error based on the value limit so that the coefficient correlation (r) between observation discharge and simulation discharge was close to 1. The values used for the index soil moisture capacity (nominal), percent sub surface (PSUB), ground water flow (GWF), and crop coefficient (kc) are 0,20; 0,85; 0,50; and 0,60.

The main principle of designing the multi-storey building is increasing the building strength on lateral force. The higher the building, then the more vulnerable the building in resisting the lateral force, such as earthquake force. In structure design in multi-storey building, there are 2 systems lateral force restraint that often used, that are frame that use shear wall and frame without shear wall. The purpose of this research is to analyze the effect of shear wall placement with respect to structure deflection as an effect of quake load also to find out the sensitivity of the adding the amount of shear wall on decreasing rate of structure deflection as an effect of quake load, that the calculation of quake load effect done by use the Equivalent Static Analysis Method. The result of the analysis obtained the structure deflection decreases with the increasing of the amount of shear wall and the average of decreasing rate of structure deflection for every addition of 1% shear wall is 1.97% also the layout of shear wall placement very react on structure deflection alteration.

Temef Dam is located in Oenino Village Oenino District and Konbaki Village Polen District, Timor Tengah Selatan Regency which has a capacity of 45.79 millions m3. This research aimed to determine the amount of potential evapotranspiration using Penman Modification Method, the amount of dependable discharge with three methods that are NRECA, F.J. Mock, and Tank Methods, from those three methods will be selected a method that have closest characteristic of Temef Watershed, and filling timein Temef Reservoir. The maximum half monthly potential evapotranspiration in Temef Watershed using Penman Modification Method is 142.72 mm and the minimum is 71,25 mm. The average of annual discharge using NRECA Method is 249.89 m3/sec, F.J. Mock Method is 258.66 m3/sec, and Tank Method is 92.15 m3/sec. Based from three methods that have been used, Tank Method is the closest method to the characteristics of Temef Watershed, which RMSE value from Tank Method is 2.99. Filling time of Temef Reservoir to reach the planned reservoir volume in normal water year condition is three months and fifteen days and in low water year condition is six months.

This research is aimed at analyzing the slope is average in a model of river bed, the slope of each section and the maximum depth of the degradation which result from the construction of permeable on the model for the river that is using moderate bends (II), of minimum discharge , average discharge and maximum discharge, in order to determine the proper course of water flow, so as to achieve balance in river beds. The scour area of the permeable groyne formation is perpendicular to the scour I (ATLG I) = 0,4800 m2 with benchmarks  ATLG I < SeDKP and scour II(ATLG II) = 0,6000 m with benhmarks ATLG II < SeDKP and the average slope of the river bed that occurs and the average slope of the river bed that occurs (Ids TL) = 0,0097 with benchmarks IdsTL <  SeDKP so that the balance of the river bed is achieved and the hypothesis is accepted
