The study presents a status report on hydrological problems of hard rock areas related to hydrological network design, groundwater quality, failure of open and borewells, regional flood formulae, groundwater balance studies, reservoir sedimentation, hydrological aspects of droughts, forest hydrology and drainage problems of black soil of the hard rock terrain.

The study reviews the present status of urbanization in the developed and developing countries and assesses the changes in urban hydrological cycle owing to this. The softwares used for studying urbanization and sanitation issues in the urban areas have been reviewed.

The report tries to review the hydrological studies done in the northeastern region of India by all agencies, governmental or non-governmental. Sufficient care has been taken to include all the salient features of the studies to make it comprehensive. The various information  included in this report are the purpose and year of study, location and extent of the study area with its brief description, data used, list of specific studies along with its results and recommendations wherever possible.

An attempt has been made to pull together all the studies related to hydrology and its allied field. Besides these planned studies done by various departments, research studies done by academic institutions and research and development organizations has also been included.

The hydrological inventory of Ganga basin provides information regarding availability of hydrological data and highlights major hydrological problems of the basins. The information is a useful input in water resources planning, management and research activities.

The study endeavors to test the Storm Water Management Model (SWMM) in an urban area. The report presents the technical summary of the model, its structure, interaction between the various blocks of SWMM, the input requirements and the output. The Windows implementation of the blocks, including descriptions of the screen sequences, corresponding blocks, changes made for ease of use and limitations of the implementation are presented. The minimum hardware requirements and installation information for the Windows SWMM are discussed.

Natural resources are limited and considering industrialization and global warming we should start focusing on preserving natural resources or need to find out optimum way to utilize these resources.

Earth, tree and water are linked to each other and due to vast industrialization we are breaking the nature rules now the time has come to give back or restore our natural resources.

The study evaluates groundwater on the basis of widely used graphical methods like Piper, Stiff and US Salinity Laboratory classification. The study concludes that, in general, the groundwater in the area varies from medium salinity to very high salinity, the latter being more common in the irrigated stretches. The irrigators are advised to ensure good land and water management practices in the fields, with particular emphasis on creating favorable leaching and drainage conditions to avoid further development of saline conditions in the area. 

The study aims to establish relationship between spectral reflectance of rice canopy, crop growth, chlorophyll concentrations and water use. Two fields were chosen for radiometric and agronomic measurements over the period from flowering to maturity (August to November).

The term skimming well is used for any technique employed with an intention to extract relatively freshwater from the upper zone of the fresh-saline aquifer. The types of skimming wells include: the conventional single strainer well, multi-strainers wells, scavenger wells, radial collector wells and dug wells.
