In this study, regional flood frequency relationships have been developed using L-moments for South Bihar, in the alluvial plains of Indo-Gangetic basin and Kaimur-Chhotanagpur Santhal Pargana plateau. The annual maximum peak flood data of twenty-two gauging sites whose catchment areas vary from 11.7 to 3171 sqkm have been used. The mean annual peak floods of these sites vary from 29.15 cumec to 1293.2 cumec. Comparative regional flood frequency analysis studies have been carried out using some of the commonly used frequency distributions viz Extreme Value (EV1), General Extreme Value (GEV), Normal, Log Pareto (GPA) and Wakeby based on L-moments approach.

A study of saline freshwater interface phenomenon in the Mahanadi delta region, Orissa
The subsurface aquifer systems in Mahanadi delta region in Orissa (India) is largely characterized by two groups of freshwater aquifer systems: 1. The south western Mahanadi delta region is represented by unconfined to semi-confined freshwater aquifers underlained by brackish/ saline aquifer systems with a diffusion boundary 2. The north eastern parts of Mahanadi delta is represented by deep freshwater confined aquifers overlained by brackish/saline water aquifers with aquitard/ aquiclude boundary. Both the systems are prone to saline water mixing/ migration with time and development. The present paper incorporates results of a simulation study using a finite element based FEFLOW model and examines saline water migration scenarios when subjected to increasing rates of pumping under steady state conditions with the help of a calibrated groundwater model. The results indicate the unconfined and semi-confined aquifer systems in the south western part of Mahanadi delta are prone for faster rates of saline water mixing of the contamination when compared to the deep confined systems in the north eastern parts of Mahanadi delta.

In this study from the GIS Development site,  the hydrogeophysical parameters generated from vertical sounding, geohydrological, inferred fractures and geomorphic zones derived from remotely sensed data have been analysed in Kewta watershed of upper Barakar Basin, Hazaribagh. The study area is part of lower Hazaribagh plateau and is part of pediplain developed over Chotanagpur granite gneiss and meta- sedimentary.
