Abstract

There are several problems related to water resources such as floods and drought. One of the critical issue is drought. Drought is a nature phenomenon which is considered as common dangers which occurs in accordance of climate cycle related to hydrological cycle that affected by rainfall. Drought that affected only by rainfall is meteorological drought which is an early indication of drought. Based on the large impact, it is necessary to analyze index of dryness to find out the level of dryness as the early warning of further droughts. The location of the research was the Batang Anai watersheds which is one of water source of agricultural sector in Sumatera Barat Province. Standardized Precipitation Index (SPI) was one of the methods to analyze drought index in an area. The calculation was done based on rainfall data of half monthly period and monthly period from 1997 to 2016 on every rain station in DAS Batang Anai. The result of SPI drought index was correlated with Indian Ocean Dipole (IOD) phenomenon and then was mapped using ARC GIS software with tools Polygoon Thiessen. The final result of this research showed that in half period the highest value of drought index was -2,3811 (January, 1st periode, 2013) with extreme drought classification. While in monthly period, the value of drought index was -1,9183 (January, 2012) with very dry classification. This research also showed the suitability of SPI drought index with IOD drought phenomenon which has suitable average 70,14%.Keywords : Drought index, Standardized Precipitation Index, GIS, Indian Ocean Dipole

Abstract

On this study to review the rainfall-runoff modeling of GR4J (Ge'nie Rural a`4parame`tres Journalier) on Watershed (DAS) Indragiri Bagian Hulu. In this study using two methods:by modeling GR4J and length of the data elaboration method for calibration and verification. This GR4J models using input data including daily data of rainfall at the Lubuk Ramo stationand daily data of evapotranspiration potential is the result of a program CropWat within input data is climatological data at Sentajo stations, modeling results is tested using daily data of discharge observations on the Pulau Berhala station. This modeling to optimize four free parameters such as Maximum Capacity Production Store (X1) is 1200,00 mm, Coefficient Changes in Ground water (X2) is 3,00 mm, Maximum Capacity Routing Store (X3) is 20,00 mm, and Peak Time Ordinate unit hydrograph (X4) 24,75 days. In the second method, performed of calibration in certainly year and verification in thereafther. As a determinant of the model’s success is use dequation NashSutcliffe Coefficient (R2) and the correlation coefficien tmethod (R) to calculate the deviation occurs.Keywords : GR4J, Calibration, Verification.

Abstract

River water level data forecasting Qn to Qn+1 by using Artificial Neural Network model approach Backpropagation algorithm produces good value if the value of the correlation between upstream and downstream AWLR good enough, it can be seen from the process of training, testing and validation of the neural network that generates the value correlation learning high enough. Where in the wake of the artificial neural network model Backporagation algorithms using MATLAB programs, such as for this parameter is Epoch = 2000, Ir = 0.1, mc = 0.9. Data Variation 70 (training) and 30 (Tests), it is proven in testing the artificial neural network model is applied to predict water levels in 2012. So this data can be a flood early warning system in the downstream areas of the river.Keyword : neural network, the back propagation algorithm, face high water forecasting

Abstract

A physical characteristic of a river is specifically able to describ by the morphometry parameters of a watershed. One method avalaible to analyze the characteristics of river stream is by itilizing the Digital Elevation Model (DEM) data obtained from the satellite image. Then this is processed by the GeographicInformation System (GIS) in order to develop river network mapping. Watershed characteristic data can be used to calculate the flood discharge using synthetic unit hydrograph method. Flood discharge data is used in many fields of waterresource design such as drainage, dams, and many others. Syhntetic unit hydrograph is the most pratical and simple method analyze flood discharge at watersheds which are not measurable. The most popular type of HSS is Gama Iand Nakayasu method. The principle of unit hydrograph with one millimeter of direct runoff is used to determine the most appropriate synthetic unit hydrograph method to be applied in watershed. In the case study of Siak-sub-watershed,Nakayasu method provides better result with less than 5% of error value and HDRO value close to 1 mm.Key words: Watershed characteristic, GIS, Gama I, Nakayasu, DRO

Abstract

Analysis of hydrological data is needed to determine the rainfall characteristics that suitable to space and time. Analysis of hydrological data can interpret the possibility of an upcoming event based on the data from the past. This interpretation uses probability distribution. The probability distribution that commonly used is Gamma Distribution, Exponential Distribution, Normal Distribution, Normal Log Distribution, Gumbel Distribution, and Log Person III Distribution. The purpose of this study was to choose the probability distribution based on Akaike Information Criterion (AIC) and to determine its compatibility with the Chi Square test and the Smirnov Kolmogorov test. The maximum likelihood value of each data distribution is evaluated by AIC value. The distribution that has the smallest AIC values were re-tested with Chi Square test and Smirnov Kolmogorov test. The results showed that in the Siak River Basin, Normal Distribution has the smallest AIC value with AIC value -2.203 for Buatan Station, -2.486 for Kandis Station, -2.939 for Pekanbaru Station and -3.184 for Petapahan Baru Station. However, Normal Distribution can not be accepted as the best distribution according to Chi Square test and Smirnov Kolmogorov test.Keywords: Akaike Information Criterion (AIC), Probability Distribution, Chi Square test, Smirnov Kolmogorov test

Abstract

There are several methods that can be used to predict discharge some future time, but the results still have relatively high error value. The use of models softcomputing a method that can be used to model a hydrological analysis such as forecasting discharge. Adaptive Neuro Fuzzy Inference System (ANFIS) is one softcomputing models that have proven reliability in conducting hydrological analysis as to forecast the flood discharge, and long reservoir inflow of seawater intrusion.Reliability ANFIS models need to be tested in the analysis of hydrological especially to predict discharge.ANFIS models were built to predict discharge using the main data is data on Tapung river left in the year 2002-2012 (except on taun 2007). Then ANFIS foresees the discharge of each of the data sources and analyze the magnitude of the error forecasting results debit ANFIS models. Then the forecast results will be compared with the results of forecasting with ANN method.Results discharge by using ANFIS models showed excellent results with test parameter value statistical correlation coefficient (R) of more than 0.75 are included in the category of correlation is very strong. To forecast results debit ANFIS models, yielding a value of correlation (R) of 0.99 while the forecast results debit ANN method produces a value of correlation (R) of 0.94903.Keywords: hydrological analysis, tidal forecasting, softcomputing, ANFIS.

Abstract

Rainfall distribution is one of the parameters required for calculations of the design flood. The pattern of rainfall distribution is the mean of rainfall expressed in a graph that describe time function to variation in depth of rainfall. The pattern of rainfall distribution is obtained in two method, empirical method and averaging hourly rainfall data. The rainfall data used is obtained from TRMM JAXA in eight years (2009-2016) for Kampar Regency. In this research, the approach of distribution form between empirical methods with the hourly rainfall data average of TRMM to simplify the acquisition pattern of rainfall distribution. The empirical method used is Alternating Block Method (ABM), Modified Mononobe, and Tadashi Tanimoto. Based on TRMM rainfall data, that rainfall duration was dominated by one hours rainfall events. The analysis results for pattern of rainfall distribution approach of TRMM JAXA with empirical method shows that designed rainfall duration (3 to 8 hours) tends to approach Alternating Block Method (ABM) pattern.Keywords: Rainfall distribution, satellite rainfall data, Alternating Block Method, Modified Mononobe, Tadashi Tanimoto
