Abstract

In the analysis of flood hydrograph to input of designed rainfall, usually rainfall parameters like as duration and rainfall distribution pattern were not available, but actually the case is very important for analysis. rainfall distribution pattern can be seen in two ways, the first is observation of rainfall events using automatic rainfall recorder and rainfall distribution model.The study using rainfall data from rainfall stations Pasar Kampar, Kampar Regency. The research was done by comparing the rainfall distribution pattern of hourly from observations method with distribution pattern of hourly using rainfall distribution model. Rainfall distribution model used is the Alternating Block Method (ABM), Modified Mononobe, and Tadashi Tanimoto. The analysis showed that rainfall in station Pasar Kampar was dominated by three hour rainfall events. Distribution of rainfall three to seven hours, rainfall distribution model ABM giving out largest deviation compared with distribution model Modified Mononobe, and for the distribution of rainfall eight hours the smallest deviation given by rainfall distribution model.

Abstract

Many studies has shown that the ANFIS  model  has good prediction performance results for forecasting hydrological phenomena such as reservoir inflow. The existence of the success, it is necessary to research the  reliability of the ANFIS models when applied to existing reservoirs in  Riau Province, namely  Koto Panjang Hydropower Reservoir. The results of  the ANFIS  models  in the  development  phase  of this  study indicate that the scheme 4 (4 inputs) with the ROI value of 0.02 is the best scheme so that the scheme is used to build the model of ANFIS. The cross validation on ANFIS models  provide  the best  performance  prediction  with  correlation coefficient (R) between the prediction values and the observational value is 0.90.

Abstract

Drainage system in Garuda Sakti street is not functioning optimally. It can be seen from the innability of drainage channels in the siphon discharge runoff. Floods cause traffic congestion and then disturbed teaching and learning activities in elementary school around the location of research. Analysis of floods was done with analyzing the drainage channels capacity and comparing it with the calculated discharge using Rasional method. The analysis of drainage capacity was conducted by using HEC-RAS version 4.1.0. Drainage geometrical analysis performed on the two types of simulations with three types time period, such as five years, ten years and twenty two years. The results on the existing condition is the maximum depth of floods is 14,30 centimeters for the five years time period, 16,40 centimeters for the ten years time period and 17,40 centimeters for the twenty years time period. Normalization with excavation depth of the channels can flood prevention and tackling effort is maximal.Key words: Flood, the rational formula, HEC-RAS

Abstract

Many rules were did to overcome flood problem which one to use remote sensing in hydrological modeling with data-based satellite. This research conduct hydrological modeling using satellite data with Integrated Flood Analysis System (IFAS) version 1.3.0 for the analysis of the flood discharge at the sub-watershed Rokan Hulu at AWLR Lubuk Bendahara Station. Satellite data of hidrological modeling was the data in February 2012. The rainfall satellite data are used GSMaP_NRT original and corrected in the form of rainfall data hourly. The parameters used to assess the accuracy of the model is wave shape error (Ew), volume error (Ev), and peak discharge error (Ep).

Abstract

Satria street is located at the flood plain of Sail River in Pekanbaru city which is oftenly flooded by high intensity rainfall during the rainy season. Due to its low elevation, water tends to flow and form puddles on the street area. This study aims to overcome the aforementioned problem by performing drainage normalization simulation at Satria Street using HEC-CRAS 4.1.0 software. The normalization was conducted by increasing both width and depth of the drainage ditch from the existing dimensions of 50 cm x 70 cm to 80 cm x 100 cm, and by changing the drainage slope at Satria Street. The design-flow rate an rainfall intensity was computed using rational method and mononobe method, respectively. The analysis result show that the flood problem can be coped by modifying the slope and dimensions of the drainage ditch.Keywords: flood, drainase, Hec-Cras

Abstract

Floods occurred in Rokan Hulu are due to heavy rainfall with fairly long duration and high rainfall. The main difficulty encountered in the analysis of river flooding in Rokan Hulu is due to limited availability of data. An alternative to overcome these limitations is to use a hydrological model. In this research was used as a calibration adjustment process model parameter values to obtain a result of the same model or close observation. This study aims to look at the characteristics of the calibration using rainfall data and flow data hourly to the Transform Method Clark Unit hydrograph and Transform Method Snyder Unit Hydrograph, by using hydrologic Engineering Center Modeling System (HEC-HMS). The best result of the calibration is to use two parameters, the results of two-parameter calibration method Transform Method Clark unit hydrograph has the result Different Percent Percent Peak = 0.0 and Different Volume = -7.67 and methods Transform Method Snyder unit hydrograph have results Different Percent Peak = 0.0 and Different Percent Volume = -23.43. From the results of the calibration is the best method is Transform Method Clark Unit Hydrograph.Keywords: DAS, debit, HEC-HMS

Abstract

Rainfall distribution pattern in Senapelan (Pekanbaru) can not be known certainly Rainfall distribution can be preditced by hourly rainfall distribution. The pattern of hourly rainfall distribution can be calculated with empirical method or observation method. Empirical method process the daily rainfall with ABM (Alternating Block Methods), Tadashi Tanimoto rainfall distribution and Mononobe Modifed method. Observation method using rainfall hourly data. Based on the analysis,the highest incidence of rain in Senapelan the duration of 3 hours. Based on the comparison chart obtained form rain duration 3 hours and 7 hours approaching dsitribusi pattern ABM (Alternating Block Methods), rainfall duration of 4 hours and 5 hours approaching Mononobe Modified distribution patterns. The comparison is based on the duration of the show that the duration of the 3, 4, 5, 6, 7, and 8 approach the distribution pattern of the ABM method (Alternating Block Methods).Keyword: Rainfall distribution, Alternating Block Methods, Modified Mononobe Methods, Tadashi Tanimoto

Abstract

Data availability for hidrologic modeling usually become a problem because of incompleteness and imprecision data. The development of advanced technology recently encourage the development of hydrological modeling by using remote sensing data. This research conducted rainfall-runoff modeling using remote sensing data and ground rainfall data with Integrated Flood Analysis System (IFAS) tools and took a case study in Tapung Kiri sub-watershed in Riau Province. This model was simulated and calibrated with rainfall-runoff periode of forward verification (2005-2006) and backward verification (2006-2005). The results of this research shows that the model to be optimal after calibration process in rain satellite data backward verification period from 1 January to 31 December 2005 by corellation value (R) 0.75, volume error (VE) of 3.22%, and coefficient of efficiency (CE) 0.9. It means that this model has a high degree of association with measurement data (0,7 < R < 1,0), the difference of volume can be tolerated ( VE < 5%), and effiency of this modeling with measurement discharge is highly efficient (CE > 0,75).Key words : rainfall-runoff modeling, satellite data, ground rainfall data, IFAS Model

Abstract

Flood calculation design requires an input of rainfall design that is distributed rainfall into hourly rainfall. Distribution of each pattern from a hourly rainfall was necessary to convert rainfall into hourly rainfall designed. Measurement Rainfall data was used utilizing satellite data. The Rainfall data was obtained from Tropical Rainfall Measuring Mission (TRMM) of satellite data. Processed of TRMM data has been done using a Command Prompt software. Data of the Satellite TRMM were extracted by Command Prompt, it was transfered by Zilla File Software which is gsmap. Duration of rainfall into hourly rainfall from 2009 to 2016 was taken one hour until sixty-nine hours. There is incidence of rain with a total of 4001 incidents of rainfall with 22.1228 mm ranifall average, and 839 was the most rainfall incidence in one hour.Keyword: Rainfall distribution, Satellite data, Tropical Rainfall Measuring Mission
