  • Rejuvenation and Beautification of River and Nala

    • Free pre-print version: Loading...

      Authors: Rutuja Kendre; L.G. Patil, Sandeep Zade
      Abstract: Nowadays almost all water bodies in India are getting more and more polluted and facing with three major problems which are likely to be Untreated Sewage, Solid waste and abetting encroachment or slums areas along the bank of River, nala or any water body. Due to population development, outdated storm water drainage systems, climate change, and poor management of utility infrastructures, significant damage has recently been done to urban areas, including Hyderabad City, the capital of Telangana. One of the most practical methods to manage these complex urban systems is using process of Rejuvenation of the Nala and pollution abetment works by diverting the incoming Sewage leading to Nala in the Designed Sewerage Systems. In this research work, the framework is prepared for Rejuvenation of Polluted Nala channel and Designing Sewerage System for sewage outfall from the abetting slums including effective management of the nala system. This study is divided into three main parts which consists of 1. Contribution of Upstream Catchment area-Determination of the contribution of Catchment flow from Upstream to Confluence point of Nala and delineation of the Catchment area. 2. Nala Channelization- The Inlet flow has been intercepted and diverted to STP and total carrying capacity of Nala is found and check has been determined. 3. Design of Sewerage System- Determining the Sewage flow generation beside the Nala and four Inlets joining the Nala. For the first stage various Design Software like Civil 3D, Power Civil, Infraworks were used to simulate the existing catchment flow leading at the Confluence point then by using capabilities of QGIS 3.16.11 software application the Drainage networks, stream orders and elevation details has been achieved. In the Second stage the carrying capacity of storm water Nala is been determined by making calculation check for total of upstream flow, storm water flow and Inlet flows. Finally the third stage determines the generation of Sewage flow tapping and diverting it to the Sewer System by Designing and optimizing it in SewerGEMs select-series 4 Software which will get carried to the Sewage Treatment Plants, thereby treating the water as per CPCB-NGT norms. The proposed strategic approach is able to abate the pollution in Nala, maintain the ecological flow and conserve the public realm along the river.

  • Validating the Gravity Recovery and Climate Experiment (GRACE) terrestrial
           water storage dataset using Terra MODIS NDVI anomaly.

      Authors: Sachin Malhari Bhere; Shweta Panaskar, Raju Narwade, Karthik Nagarajan
      Abstract: The Gravity Recovery and Climate Experiment (GRACE) is the advance tool for mapping the changes in the gravitation field of the earth. The satellite launches in 2002 and the follow off mission is in 2016. The gravitational changes of the earth are downscaled into the changes in the mass with the different algorithm by three institutions. Further the mass anomaly is converted into the equivalent water thickness of the terrestrial water storage which comprises of different water component which can be used and modelled for different application. The objective of this paper is to validate the GRACE data for soil moisture and land use analysis using MODIS NDVI anomaly. For calculating NDVI index Moderate resolution imaging spectroradiometer (MODIS) vegetation index product is used. NDVI is used to determine the condition of healthy vegetation. It ranges from -1 to 1. These values represent the health of vegetation. Values near one represent the healthy vegetation. It is calculated by taking ratios of spectral reflectance of NIR and Red spectrum of electromagnetic wave. The study shows the GRACE includes all aspects of water storage deficit including groundwater and soil moisture which important for region like Western Ghat as many farmers depends on ground water resources like well and borewells. NDVI sometimes fails to show the monsoon drought condition but it can be used to for characterization of post monsoon condition as it shows the vegetation health index. The study significant correlation with GRACE and NDVI, one should adopt these indices for characterization of Vegetation, soil moisture and canopy cover.

  • Estimation of Peak Flood Discharge for the Ungauged Catchments in the
           Tributaries of River Sutlej using Synthetic Unit Hydrograph Approach

    • Free pre-print version: Loading...

      Authors: C. Srishailam; N. Vivekanandan
      Abstract: Estimation of peak flood discharge (PFD) for a given return period is of utmost importance for planning and design of hydraulic structures, river protection works, and development of integrated water resources management projects which can be computed by applying various approaches viz., flood frequency analysis, rational formula, envelope curve and synthetic unit hydrograph (SUH). In this paper, SUH approach is adopted for estimation of PFD for the ungauged catchments viz. Saisso Khad up to Giabong village, Saisso Khad between Giabong and Rushkling villages, and Kannam Nallah up to Kannam Village (viz. Kannam Khad) in the tributaries of river Sutlej in Tehsil Pooh, Kinnaur District, Himachal Pradesh. For this purpose, rainfall depth (i.e., 24-hour maximum rainfall) is considered as one of the inputs which can be estimated through extreme value analysis (EVA) by fitting Extreme Value Type-1, 2-parameters Log Normal and Log Pearson Type-3 (LP3) distributions to the annual 1-day maximum rainfall data series. The estimators of the parameters of the distributions are determined by method of moments and used for estimation of rainfall for different return periods. Goodness-of-Fit (viz. Chi-square and Kolmogorov-Smirnov) and diagnostic (viz., D-index) tests are applied for checking the adequacy of fitting probability distributions adopted in EVA. The rainfall depth is computed by multiplying the estimated 1-day maximum rainfall using LP3 with 1.15 and used as an input for estimation of PFD. The paper presents the procedures adopted in estimation of PFD for the ungauged catchments in the tributaries of river Sutlej using SUH and the results obtained thereon.

  • Extreme Value Analysis of Rainfall using L-Moments of Five Probability
           Distributions for Chandwa and Latehar Sites in Jharkhand

    • Free pre-print version: Loading...

      Authors: N. Vivekanandan
      Abstract: Estimation of rainfall for a given return period is of utmost importance for planning, design and management of civil and hydraulic structures. This can be achieved by conducting Extreme Value Analysis (EVA) of rainfall that consists of fitting probability distributions (PDs) to the annual maximum series of rainfall. In this paper, a study on intercomparison of L-Moments (LMO) of five PDs viz., Extreme Value Type-1 (EV1), Extreme Value Type-2, Generalized Extreme Value (GEV), Pareto and 2-parameter Log Normal for estimation of rainfall for Chandwa and Latehar sites is carried out. The adequacy of fitting five PDs adopted in EVA of rainfall is quantitatively assessed by applying the Goodness-of-Fit (viz., Chi-square and Kolmogorov-Smirnov) and diagnostic (viz., D-index) tests, and qualitatively assessed by using the probability plots of the estimated rainfall. The EVA results of rainfall indicate the GEV is better suited distribution for rainfall estimation for Chandwa while EV1 for Latehar.

  • ASSESSMENT OF BUILDING AGAINST FLOOD

    • Free pre-print version: Loading...

      Authors: Birendra Kumar Singh
      Abstract: Flood problem is vital problem for building, railway track, highway etc. Thrust of water due to standing water & velocity of flow taken place on building i.e. above G.L. & below G.L. due to percolation of water. If 70 cm thick layer of silty sand is spread all around the building the percolation of water below G.L. is prevented. Here analysis is made due to thrust taking place of water below G.L. & velocity of water. Above G.L. the thrust exerted by water is sustained by brick masonry which strength is 6 kg/cm2.  Below G.L. the soil may be sandy or clayey.

  • Computation Analysis of Selected Communities Water Quality Assessment

    • Free pre-print version: Loading...

      Authors: C. Ukpaka; B.G. Jephter
      Abstract: The study is aimed at evaluating water quality based on assessed parameters for Ede, Erema, Obagi and Oboboru Communities groundwater. The mathematical computations using water quality index model (WQI) reveals WQI ranges as 53.89, 23.85, 33.06 and 36 for Ede, Erema, Obagi and Oboboru Communities indicating poor water quality for Ede Community and good water quality for Erema, Obagi and Oboboru Communities. Therefore, there is need to treat groundwater from Ede Community before it will be supplied to the general public.
