    Description / Table of Contents: Performance improvement of usbr vi stilling basin model for pipe outlet -- Rain water harvesting for the main campus of jaipur national university, jagatpura, Jaipur -- Bio Inspired Genetic Algorithm for Optimal Design of Water Distribution Networks -- Drought assessment using various drought indices: a case study of banaskantha district -- Top surface soil moisture retrieval using c- band synthetic aperture radar over kudremukh grasslands -- Meteorological drought assessment in the bharathapuzha river basin -- Experimental and numerical analysis of mean pressure coefficient on C-shaped building with and without round corner. .
    Abstract: This book carefully considers hydrological models which are essential for predicting floods, droughts, soil moisture estimation, land use change detection, geomorphology and water structures. The book highlights recent advances in the area of hydrological modelling in the Ganga Basin and other internationally important river basins. The impact of climate change on water resources is a global concern. Water resources in many countries are already stressed, and climate change along with burgeoning population, rising standard of living and increasing demand are adding to the stress. Furthermore, river basins are becoming less resilient to climatic vagaries. Fundamental to addressing these issues is hydrological modelling which is covered in this book. Integrated water resources management is vital to ensure water and food security. Integral to the management is groundwater and solute transport, and this book encompasses tools that will be useful to mitigate the adverse consequences of natural disasters.

    Description / Table of Contents: Effect of bed permeability on flow turbulence in gravel-bed stream -- Study on Erosion and Undercut of Cohesive River Bank – An Experimental Approach -- Hydraulic design of reservoir in permeable pavement for mitigating urban storm water -- Analytical expression for measurement of discharge using conical obstruction in a small rectangular channel -- Efficient numerical algorithm for flow field around vertically submerged tandem and aligned circular cylinders. .
    Abstract: This book presents key principles of the hydraulics of river basins, with a unique focus on the interplay between stream flows and sediment transport. Addressing a number of basic topics related to the hydraulics of river systems, above all it emphasizes applicative aspects in order to provide the reader with a solid grasp of river engineering. The understanding of the river hydraulics is essential for the assessment of optimum locations for the conservation of water resources and its structures. This book will be interesting to readers and researchers working in the specialized area of river hydraulics of Ganga basin, Narmada, Tapi, Godavari, and other basins of India. It consists of review on hydraulics of meandering river; hydraulic design of reservoir in permeable pavement; optimization of hydraulic design; hydraulic investigations to optimize the design of spillway and design of energy dissipater; and analysis of performance of orifice spillway using computational fluid dynamics.

    Dielectric studies of molecular complexes ofDDT with some compounds of biological interest (1981)

    Description / Table of Contents: Zusammenfassung Es wurden Molekülkomplexe vonDDT (als Acceptor) mit einigen Verbindungen von biologischem Interesse (als Donoren: Indol, 2-Methyl-indol, 3-Methyl-indol, Benzol und Naphthalin) mittels Brechungsindex,Guggenheim-Methode und dielektrischer Titration untersucht. Dipolmomentberechnungen ergaben, daß die intermolekulare Wechselwirkung von einer Anziehung induzierter Dipol-Dipol bestimmt wird; es wurde auch der charge-transfer-Anteil des Dipolmoments abgeschätzt. Alle diese Daten unterstützen die Annahme der charge-transfer-Komplexierung vonDDT.
    Notes: Abstract The molecular complexation ofDDT (acceptor) with some compounds of biological interest as donors (e.g. indole, 2-methylindole, 3-methylindole, benzene and naphthalene) have been studied using refractive index,Guggenheim and dielectric titration plot methods. The interaction between these donors with solvents (CCl4 and C6H6) have also been observed by calculating μind through μind=μsol−μinert. These data have shown that the molecular interaction between polar solutes and non-polar aromatics is governed by dipole-induced dipole electrostatic attraction. The dipole moment obtained due to charge transfer (μDA) has also been calculated and found that its value increases with the increase in the extent of interaction between donor and acceptor. These data support the charge-transfer complex formation hypothesis for the mode of action ofDDT on molecular level.

    Description / Table of Contents: Zusammenfassung Es wurde die Bildung von Molekülkomplexen zwischenDDT als Acceptor und Indol, 2-Methyl-indol, 3-Methyl-indol, Benzol und Naphthalin als Donor in CCl4 mittels Refraktometrie und differenzieller Refraktometrie untersucht. Es wurde1∶1-Stöchiometrie der Komplexe festgestellt, Gleichgewichtskonstanten und das Ausmaß der Elektronenpolarisation wurden berechnet. Zwei Typen von Komplexen wurden beobachtet; in einem Fall erfolgt die Assoziation primär über die Benzhydryltrichlormethyl-Gruppierung desDDT, im anderen Fall über π-Elektronenwechselwirkungen. Die Daten unterstützen ein chargetransfer-Modell der Komplexbildung vonDDT mit geeigneten Donormolekülen.
    Notes: Abstract Formation of molecular complexes betweenDDT as acceptor and indole, 2-methylindole, 3-methylindole, benzene and naphthalene as donors have been studied in carbon tetrachloride using refractometric and differential refractometric measurements. Titration techniques through these measurements have indicated1∶1 stoichiometry of these complexes. Equilibrium constants (K 1) and extent of electronic polarization were calculated. Two types of complexes were observed, one association involving primarily the benzhydryltrichloromethyl grouping ofDDT with a polar complexing agents, and the other interaction of theDDT aromatic π-electron system with π-electrons of donors in the complexing molecule. These data support the charge-transfer complex formation hypothesis for the mode of action ofDDT on molecular level.
