Flood frequency analysis of river kosi, uttarakhand, india using statistical ...eSAT Journals
Abstract In the present study, flood frequency analysis has been applied for river Kosi in Uttarakhand. The river Kosi is an important tributary of Ganga river system, which arising from Koshimool near Kausani, Almora district flows on the western side of the study area and to meet at Ramganga River. The annual flood series analysis has been carried out to estimate the flood quantiles at different return period at Kosi barrage site of river Kosi. The statistical approach provided a significant advantage of estimation of flood at any sites in the homogenous region with very less or no data. In the at –site analysis of annual flood series the Normal, Log normal, Pearson type III, Log Pearson type III, Gumbel and Log Gumbel distribution were applied using method of moments . From the analysis of different goodness of fit tests, it has been found that the Log Gumbel distribution with method of moment as parameters estimation found to be the best-fit distribution for Kosi River and other sites in the region. It is recommended that the regional parameters for Kosi Basin may be used only for primary estimation of flood and should be reviewed when more regional data available. Keywords: Flood Frequency Analysis, River Kosi, Annual Peak Flood discharge, Return Period, Goodness of fit Test.

Harmonic analysis and Power factor improvement with UPQC under two Novel cont...IJERA Editor
This paper presents unified power quality conditioner (UPQC)for power quality improvements in terms of
harmonics compensation and power factor correction in a three-phase four-wire distribution system.The UPQC
is implemented with PWM controlled voltage source converter (VSC) and switching patterns are generated
through Indirect PI and Synchronous Reference Frame controller. The selected topology for voltage source
converter is the three-leg and six-leg VSC for Indirect PI and Synchronous reference frame (SRF) control
strategies respectively. The behavior of UPQC has been analyzed by considering a case study with switching of
three phase half bridge diode rectifier and a parallel star connected unbalanced R-L loads. Harmonic spectrum
of the source current and load voltage are compared in between without UPQC and with UPQC by considering
both control strategies. The complete system has been modeled using MATLAB software with its stimulus’s
sim power system toolboxes.
Computer Based Free Vibration Analysis of Isotropic Thin Rectangular Flat CCC...theijes
The paper is aim at the development of a computer program for free vibration analysis of an all-round clamped (i.eCCCC) rectangular thin isotropic plate. Polynomial-based shape function for a CCCC plate, was used in Ritz energy equation to formulate an equation in term of a non-dimensional parameter 'k' for calculating the fundamental natural frequency of the plate. Computer program based on the formulated equation was develop in Matlab language for calculating fundamental natural frequency of a CCCC rectangular thin isotropic plate subjected to free vibration. To validate the values of the fundamental natural frequency obtained from the program, comparison was made between the values obtained and those available in relevant existing literatures. And the average percentage difference was 0.079% which is acceptable. Hence, it can be deduce that the computer program can be adopted as a better and faster alternative to the former rigorous approaches for obtaining the fundamental natural frequency of CCCC plate.
Water scarcity is the lack of fresh water resources to meet the standard water demand. There are two type of water scarcity. One is physical. The other is economic water scarcity.
CFD Simulation of By-pass Flow in a HRSG module by R&R Consult.pptxR&R Consult
CFD analysis is incredibly effective at solving mysteries and improving the performance of complex systems!
Here's a great example: At a large natural gas-fired power plant, where they use waste heat to generate steam and energy, they were puzzled that their boiler wasn't producing as much steam as expected.
R&R and Tetra Engineering Group Inc. were asked to solve the issue with reduced steam production.
An inspection had shown that a significant amount of hot flue gas was bypassing the boiler tubes, where the heat was supposed to be transferred.
R&R Consult conducted a CFD analysis, which revealed that 6.3% of the flue gas was bypassing the boiler tubes without transferring heat. The analysis also showed that the flue gas was instead being directed along the sides of the boiler and between the modules that were supposed to capture the heat. This was the cause of the reduced performance.
Based on our results, Tetra Engineering installed covering plates to reduce the bypass flow. This improved the boiler's performance and increased electricity production.
It is always satisfying when we can help solve complex challenges like this. Do your systems also need a check-up or optimization? Give us a call!
Work done in cooperation with James Malloy and David Moelling from Tetra Engineering.

Flood: Situation having excessive Stage of a river
generally above Full River Level(FRL).
Frequency: Number of time that a given magnitude of event
may occur in a given Return Period.
Analysis: Procedure adopt for evaluation.
3. REASONS
Estimation of Flow i.e. Possible Flood Magnitude.
Safe design of Hydraulic Structures i.e. Dams, Culverts etc.
More Reliable and Logical approach.
Knowledge Flood insurance and Flood zoning.

4. Statistical Analysis
Annual Maximum Series Partial Duration
Series
One Discharge i.e. Peak per Year
N>20, AMS is adopted
More than one Discharge/Year
Used for Independent Event
N<5,PDS is adopted
Time Series
Flow represented by Series of ordinates
at equally interval of Times.
Day unit is taken rather than month or

7. Introduction
Peak Flood Magnitude is prerequisite for Planning ,Operation and Post
Commissioning of Hydraulic Structures.
Gumbel’s Distribution is adopted only because of Peak Flow Data are
Homogeneous & Independent hence lack long term trends, the river is less
regulated ,flow data cover a long record and is of good quality.
Objectives
To develop a Mathematical Model between Peak Flood
Discharge & Return Period from a given 6-hr UH.
To estimate of Qp (Peak Flood Discharge) at any
desired value of T (Return Period).

21. Discussion: 1. Value of the Variate XT is unbounded. Variation of X1, XT
and X2 with T are truly convergent in nature.
2. Empirical model has been compared with the model
developed here by Gumbel’s method (Table 3).
3. Qp for a given Return Period (T) computed by two models
mentioned above do not vary too much
4. For a given Return Period (T) , Qp can be computed by any
of the two models, particularly at higher values of Return
Period (T).

22. Conclusion: 1. The entire water resource of river Subernarekha is largely
untapped. Hence, construction of hydraulic structures will be
helpful for resource generation also.
2. For any anticipated T, XT can readily be estimated from the
developed model as shown in the Figure-3 and corresponding
equation has also been furnished there.
3. The Stage (G), corresponding to XT can be estimated.These
Stages may be obtained from Stage-Discharge (G-Q) model.
4. If presently adopted Danger level for ‘Flood’ for the river
Subernarekha at the gauging site, is lower than the stage
computed from (G-Q) model, then there is no problem and
vice versa. Sanjan Banerjee
