Development of a conceptual model for snow, glacier and rainfed catchments - A research report by National Institute of Hydrology
Posted on 29 Jun, 2010 10:47 PMIn this report, a conceptual model is proposed and described for calculation of streamflow runoff arising from rainfall, snowmelt and glacier melt for the Himalayan basins. The simple structure of the model is designed keeping in view the sparse network, the availability of data and topography of the Himalayan basins. The model is based on the area-elevation characteristics of the watershed and utilizes the relationships describing the temperature lapse rates and orographic precipitation distribution.
Review of methods analyzing pump test data - A research report by National Institute of Hydrology
Posted on 29 Jun, 2010 10:34 PMThe methods of pump test analysis reviewed in this report has been classified as traditional, computer based and new graphical. Quantitative data on hydraulic characteristics of aquifers including transmissivity and storativity are essential to the understanding and solution of aquifer problems and the proper evaluation and utilization of groundwater resources.
Procedures for systematic processing of rainfall data - A research report by National Institute of Hydrology
Posted on 29 Jun, 2010 08:33 PMThe report is an attempt to compile the procedures for systematic processing of rainfall data. The concepts of rainfall data processing have been discussed. It provides computer programs that are meant for processing and analysis of rainfall data collected from various sources. Different well documented computer programs, their description with input specifications and test input are given in the report.
Soil moisture movement and recharge to groundwater using Tritium tagging techniques in Hardwar - A research report by National Institute of Hydrology
Posted on 29 Jun, 2010 08:27 PMThe study looks at soil moisture movement and recharge to groundwater using nuclear methods like tritium tagging. It estimates the recharge to groundwater due to monsoon rain and irrigation through the unsaturated porous media in case of cultivated and uncultivated fields.
Application of a modified SCS-CN model - A research report by National Institute of Hydrology
Posted on 29 Jun, 2010 10:20 AMIn 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.
Calibration of a catchment model using Shuffled Complex Evolution Algorithm (SCE-UA) - A research report by National Institute of Hydrology
Posted on 29 Jun, 2010 12:17 AMThe study attempts to apply the Shuffled Complex Evolution Algorithm (SCE-UA) of Duan et al for the calibration of a Conceptual Rainfall Runoff (CRR) model. CRR modeling lies intermediate between physically based models and black box models.
Flood estimation for large catchments using deterministic approach – A research report by National Institute of Hydrology
Posted on 28 Jun, 2010 08:04 PMThe report presents an interactive software that has been developed to not only provide design flood estimates for large as well as small sized catchments but also help the users analyse their historical rainfall-runoff records for calibration and validation of the various techniques for part or whole of the catchment and river reaches.
Software for reservoir analysis – A research report by National Institute of Hydrology
Posted on 28 Jun, 2010 05:14 PMThe report describes a software developed by the National Institute of Hydrology (NIH) for reservoir analysis in view of the importance of reservoir operation problem in the Indian context and the non-availability of generalized software for reservoir analysis.
Spectral response of rice plant canopy – A research report by National Institute of Hydrology
Posted on 28 Jun, 2010 04:26 PMThe study was conducted with the objective of establishing the relationship between spectral reflectance of rice canopy and crop growth. Significant relationship was developed between spectral indices and growth period. The coefficient of correlation between crop growth period and spectral reflectance ranged from 0.41 to 0.97 for the plant growth stages and canopy reflectance in single band and ratio spectra.
