Integrated hydrological data book (non-classified river basins) by Central Water Commission, Ministry of Water Resources

This data book published by Central Water Commission (CWC) is a compendium of important hydrological information on major basins in India. It provides updated site wise data for 12 non-classified basins that covers aspects such as location, drainage area, population, temperature, average runoff, seasonal water flow, historical water levels, average sediment load, water quality parameters and land use statistics. The statistics of year 2006-07 to 2009-10 are used as the base for the data mentioned in the book.

Climate change impacts, mitigation and adaptation - Science for generating policy options in Rajasthan

This paper by Rajasthan Pollution Control Board on climate change impacts in the context of Rajasthan seeks to address the issue of need of the society for robust knowledge to pursue strategies for mitigation as well as adaptation in order to address the challenges associated with global warming and climate change.

Accordingly, here a brief review of the available literature and an annotated bibliography of published research on climate change impacts, mitigation and adaptation in order to facilitate the identification of policy options in Rajasthan is provided.

Also included is the literature on how human societies contribute to environmental change and how, in turn, become vulnerable to these changes. It also explores the available knowledge on how likely ecosystem goods and services are impacted to climatic oscillations (environmental sensitivity) and the ability of rural communities to cope (social resilience) with those changes.Read More

Estimation of geomorphology parameters for small catchments using GIS – A research report by National Institute of Hydrology

The report deals with the estimation of geomorphology parameters for small catchments using Geographical Information Systems (GIS). Stream channel morphology is literally the study of stream channel form and structure, but generally it is taken to mean their form and structures regarded as a whole or their collective morphology features. Systematic analysis of morphometry of any drainage basin and its stream system is of great importance in understanding the hydrological behavior of the basin.Read More

Application of a modified SCS-CN model - A research report by National Institute of Hydrology

In this study, the modified version of the Soil Conservation Services-Curve Number (SCS-CN) by Mishra and Singh (1998a) was employed to the data of 14 watersheds falling in the arid (Rajasthan) and 2 watersheds in the sub-humid (Madhya Pradesh and Uttar Pradesh) regions of India and the results were compared with those of the existing SCS-CN method. The modified version is found to perform better than the existing SCS-CN method in all applications to the data of 16 watersheds.Read More

Application of Geomorphological Instantaneous Unit Hydrograph and Geographical Information Systems based approach for flood estimation – A research report by National Institute of Hydrology

The study attempts to apply Geomorphological Instantaneous Unit Hydrograph (GIUH) and Geographical Information Systems (GIS) based approach for flood estimation. The design storm data of four catchments along with morphological characteristics have been considered. The geomorphological parameters and time area diagrams for each of the dam catchments were generated using the GIS package, Integrated Land and Water Information Systems (ILWIS).

The geomorphological parameters together with the time-area diagram forms an important input for the GIUH based Clark model. This model has been applied for deriving the instantaneous unit hydrograph and thereby to estimate the design flood in four dam catchments located in Luni and Chambal basins in Rajasthan viz. Jawai, Sei, Gamabhiri and Alnia. A review of the previous studies carried out using GIUH approach has been presented. Furthermore, a review of studies carried out using GIS techniques is also provided.Read More
