The total energy equation is also used to extract an explicit relationship for energy loss based on turbulence parameters. The findings are presented in the form of the application of the relationship to calculate the energy loss based on simulation results for subcritical turbulent flow and hydraulic jump in open-channel transitions, which leads to identifying the effect of non-homogeneity and anisotropy of turbulence on flow energy balance. The results show that the work done by viscous shear stresses, the viscous diffusion of turbulence, and the turbulent diffusion have little to no effect on the total mechanical energy budget of open-channel turbulent flows; instead, the effect of the variations of turbulent kinetic energy and the work done by turbulence stresses is more significant. The benefit of using the modified energy equation is demonstrated by the potential for evaluating the details that were not previously considered.KEYWORDS: Mechanical energy lossenergy budgetturbulent flowdifferent hydraulic regimesnumerical simulations Disclosure statementNo potential conflict of interest was reported by the authors.Data availability statementAll data and models generated or used during the study appear in the submitted article.Notes1. second order, upwind-biased, unbounded.Additional informationFundingThis research received no specific grant from any funding agency in the public, commercial, or not-for-profit sectors.

Vegetation in the open-channel flow significantly affects the velocity of flow. In the present study, influence of the flexible vegetation on the flow characteristics of open-channel flow was resolved numerically using computational fluid dynamics. For the numerical study of the open-channel flow with flexible vegetation, fluid–structure interaction (FSI) is used. The obtained results were then compared with the numerical results of rigid vegetation. The influence of different parameters such as depth of flow, flow velocity, slenderness ratio of vegetation and density of vegetation were studied. It was found that incorporation of FSI in the analysis is essential to accurately predict the flow characteristics. It was also found that the simulation using FSI is more critical in case of submerged vegetation in an open-channel flow for all flow velocities.KEYWORDS: Flexible vegetationcomputational fluid dynamicsfluid–structure interaction List of Abbreviations Abbreviations=DefinitionsCd=Drag coefficientCFD=Computational fluid dynamicsFSI=Fluid structure interactionLES=Large Eddy simulationsVOF=Volume of fluidDisclosure statementNo potential conflict of interest was reported by the author(s).","PeriodicalId":38206,"journal":{"name":"ISH Journal of Hydraulic Engineering","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2023-11-02","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"135875552","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The present study was taken up to develop a methodology for obtaining a gridded Penman-Monteith (PM) ET0 dataset for Karnataka State, India, through spatial interpolation of estimates obtained at climate stations. Three interpolation techniques, Inverse Distance Weighted (IDW), Kriging, and Point-Based Sentinel Hospitals Area Distance (P-BSHADE), were employed to derive PM ET0 estimates. Considering the historical climate records of 67 stations located in Karnataka State for the period of 2006–2016, the interpolation methodologies were evaluated using a cross-validation procedure. Results showed that the performance of IDW was better with significant error reduction at validation sites. Subsequently, the IDW algorithm was used to derive daily PM ET0 values at 0.25° × 0.25° grids over the Karnataka State, India. Finally, the comparative analysis of developed PM ET0 gridded data product against three global ET0 products indicated the developed gridded ET0 to be most accurate across different agroclimatic zones. Web links of the developed product have been created in an effort to share the data on ET0, which is a critical input in a variety of studies in earth sciences.KEYWORDS: Penman-Monteithspatial interpolationIDWKrigingP-BSHADE AcknowledgementsWe are grateful to the Water Resources Development Organization (WRDO), Government of Karnataka, for providing the climate dataset used in the study and to three anonymous reviewers whose critical comments improved the quality of the manuscript.Disclosure statementNo potential conflict of interest was reported by the authors.Data availability statementData are openly available in a public repository that does not issue DOIs.The dataset developed in this study is stored in a repository and available in-text data citation.","PeriodicalId":38206,"journal":{"name":"ISH Journal of Hydraulic Engineering","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2023-10-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"136067879","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

{"title":"Meander geometry characteristics as a response to hydraulic and lithologic control in the active floodplains of Lower Nagar basin","authors":"Pranay Paul, Biswajit Das, Nanigopal Sarkar, Rumki Sarkar","doi":"10.1080/09715010.2023.2269127","DOIUrl":"https://doi.org/10.1080/09715010.2023.2269127","url":null,"abstract":"ABSTRACTThe present work aims to evaluate the controlling factor of meander geometry in the alluvial rivers. The assimilation of lithologic and hydraulic analysis of the meandering channels puts new insight to the understanding of the meander geometry. The study compares two highly contrasting meandering rivers of Nagar and Kulik in the Lower Nagar Basin, India. To assess the connection between the meandering nature with the hydraulic and lithologic factors, extensive field survey was made during the bank-full monsoon period. The principal component analysis between the hydraulic variables and meandering components suggests that the hydraulic factors of Nagar more effectively control the bend structure of the river, whereas the lithology of the Kulik river controls the meandering planforms. The meander patterns have shown significant transition flowing over different lithologies of grainsize combinations. The statistical prediction based on the hydraulic functions was used to predict the future possible changes in meandering planform. Moreover, the implication of the result was validated with the past century changes and thus can be suitable for the river management practices. In general, the meandering dimensions (in terms of λ, Am and Rc) are found to be maximized when finer materials are prevalent and vice-versa.KEYWORDS: Meander geometryhydraulic controlGrainsize statisticssoil grain phi scale (Φ) AcknowledgementsThe authors are grateful to the local people for their support during the field survey.Disclosure statementAuthors state that they have no known conflict of interest financially or academically that would influence the research work.CRediT authorship contribution statementPranay Paul: Data curation, Formal analysis, Investigation, Methodology, Visualization, Writing – original draft & Validation, Review & editing.

Understanding and characterizing these interactions are crucial for effective water resource management. In recent decades, there has been considerable attention and progress in addressing GW-SW interaction problems. The integration of surface and subsurface water modeling has emerged as a practical approach to simulate GW-SW interactions and inform the development of best management practices (BMPs) for water resource management. To effectively simulate GW-SW interactions, a clear understanding of coupling techniques is essential. This study reviews various integrated modeling approaches applied to simulate GW-SW interactions in water resources management. The identified gaps in GW-SW interaction modeling approaches are categorized into three groups: 1) physically based models, 2) surrogate-based models, and 3) simulation-based optimization models. The objective of this study is to make a contribution to the classification of integrated modeling approaches and provide insights into the advantages and limitations of different techniques. Ultimately, this research aims to establish a standard for selecting an appropriate simulation tool for GW-SW management based on specific limitations and requirements.KEYWORDS: Groundwatersurface waterphysically based modelsurrogate based modelsimulation based optimization model Disclosure statementNo potential conflict of interest was reported by the author(s).","PeriodicalId":38206,"journal":{"name":"ISH Journal of Hydraulic Engineering","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2023-10-03","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"135695975","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
