In this paper, all possible flood-causative factors of road flooding have been investigated. Representative indicators have been chosen to reduce the mutual influence and its derivative, including road characteristics, climatic factors, hydrological characteristics, geology environmental factors (topographical characteristics) and social factors (human activities).

(BQ) Ebook Engineering hydrology (Third edition): Part 1 is presented in four chapters. The characteristics of flood hydrographs and the unit hydrograph theory together with an introduction to instantaneous unit hydrograph are covered insufficient detail with numerous worked examples in Chap. 6. Floods, a topic of considerable importance, constitute the subject matter of Chap. 7 and 8. While in Chap. 7 the flood-peak estimation and frequency studies are described in detail, Chap. 8 deals with the aspects of flood routing, flood control and forecasting.

In recent years, the construction of upstream reservoirs and the extraction and structural construction activities on the river banks and beds have caused downstream changes in river morphology and hydrological regime of the Red river system, which has especially accelerated from 2000 to 2018. These dramatic variations have significantly changed the morphological characteristics and relationship between the flow and morphology that are a fundamental parameter to evaluate the stability of the channels.

This experiment was conducted at Dept.of Soil and Water Conservation and Engineering, CAET, OUAT, Bubaneswar, Odisha, India. It was conducted to estimate the hydrologic parameters of 67E/17 watershed of Kandhamal district under North- eastern ghat zone. In this study the various hydrological parameters of 67E/17 watershed of Kandhamal district was found out using the topo sheet.

Watershed is generally considered as the smallest unit to get hydrological response of any developmental activity. To work out a comprehensive development plan for optimum use of natural resources the study of watershed characteristics is necessary. Watershed characteristics can be understood from the morphometric analysis and which can be better analyzed by GIS. The aim of the present study is to understand the morphometric characteristics of Katra watershed of Koraput, Odisha, situated in part of Eastern Ghats, an ecologically sensitive region using GIS.

This paper presents an integration approach involving Remote sensing / Geographic information system(RS /GIS) and hydrological models to characterized and quantify the effect of land use/ land cover (LULC) change on basin hydrology parameters. The Arc SWAT model was used daily weather and stream flow data of Upper Narmada basin from 1989 to 2011. Study evaluates change in Surface runoff, Evapo-transpiration, Total water yield, stream flow and Total aquifer recharge. Further analysis present additional evidence that changes in vegetation cover altered the hydrological response to region.

Watersheds are natural hydrological entities that cover a specific aerial expanse of land surface from which the rainfall runoff flows to a defined drain, channel, stream or river at any particular point. In the last two decades, watershed management has gained the top most priority in water resources sector necessitating delineation of watersheds upto mini watershed level in order to take up watershed development and management programmes. Prerequisite for watershed management is knowledge of watershed characteristics like slope, relief, aerial extent and drainage networks.

Land use cropping pattern are altering the hydrologic system and have potentially large impacts on water resources. The present study aims at analyzing the impact of various cropping patterns on water quality parameters of rivers located at Pantnagar, for a duration of three months from August, 2017 to October, 2017. Three sites Barour (S1), Beni (S2) and Chakpheri (S3) were selected which exhibits different cropping pattern in their catchment area i. e. Paddy (Oryza sativa), Dhaincha (Sesbania bispinosa) and Maize (Zea mays) respectively.

Hydrological modelling is a powerful technique of hydrologic system investigation for both the research hydrologists and the practicing water resources engineers involved in the planning and development of integrated approach for management of water resources. In present study, the observed rainfall and runoff data of 2010, 2011, 2013 and 2014years were used as input data. In ANN, input data was divided in 70 per cent, 15 per cent and 15 per cent for training, testing and validation purpose, respectively.

The Yellow River Delta Wetland is one of the youngest wetlands, and also the most complete, extensive wetlands in China. The wetland in this delta is ecologically important due to their hydrologic attributes and their roles as ecotones between terrestrial and aquatic ecosystems. In the study, the spatial and temporal variation characteristics of CH4 and CO2 emission flux under five kinds of land use types in the wetland were investi gated.

A realistic new sediment–laden water prediction computer model was developed. In this model unsteady non-uniform flow computations were incorporated. Using this model, flooding flow–sediments were simulated and compared to earlier research including hydrologic engineering centre (HEC-series) computer models. Uncertain value of parameters and errors in flow–sediment transport equation in existing coupled flow–sediment models were studied.

The Baltic Sea is one of the most investigated water bodies in the world. For decades, the many highly industrialised nations around the Baltic have financed basic and applied investigations, as well as the building and development of research stations and vessels. After World War II, research in the Baltic Proper was intensified and investigations became much more international. The main goals of such investigations were analysis of the eutrophication and pollution of the Baltic Sea, and development of mitigating strategies (e.g. the HELCOM-Program).

3 Soil Bioengineering The transformation of watersheds is a characteristic of human civilization. Humans transform natural landscapes into various kinds of “land use” that provide them with habitation and resources. Altered hydrology and soil erosion occur as a consequence of these transformations.
