Daily rainfall-runoff modeling of Brahmani river at Rengali reservoir – A research report by National Institute of Hydrology

The report presents a hydrologic simulation model, HYSIM for modeling the daily flows of the Brahmani river at Rengali reservoir in Orissa. Considering the large catchment area of 25,250 sqkm at Rengali reservoir, for modeling purposes the basin has been divided into two sub-basins viz, Upper Sub-basin and Lower Sub-basin. The Upper Sub-basin having a catchment area of 16,900 sqkm up to Bolani gauging site is treated as a nominal sub-basin since the daily flows from this sub-basin as recorded at Bolani gauging site are available.Read More

Modeling of surface runoff, infiltration and evapotranspiration – A research report by National Institute of Hydrology

In this study, a model has been developed considering surface flow component and subsurface flow component along with the evapotranspiration from the crop as the sink term for the Lokapavani area of KR Sagar command of Karnataka. The surface flow component is represented using one-dimensional St-Venant equations and the subsurface flow component is represented using one-dimensional Richards equation with the sink term for the evapotranspiration from crop.Read More

Drought characterization in arid and semi-arid climatic regions of India – A research report by National Institute of Hydrology

The report attempts drought characterization in arid and semi-arid climatic regions of India. Drought frequency and intensity are a function of the dimensionless climatic parameter derived as a ratio of mean annual potential evapotranspiration to mean annual precipitation (Ep/Pa).Read More

Drought characterization in sub-humid climatic region - A research report by National Institute of Hydrology

The study defines the climatic regions in terms of readily available climatic parameters like ratio of mean annual precipitation to global terrestrial mean annual precipitation and ratio of mean annual potential evapotranspiration to mean annual precipitation (Ep/ Pa).

The study focuses on the drought characteristics of the sub-humid climatic regions across different parts of the country. It establishes that the drought frequency and intensity have a significant relationship with the above regional climatic parameters. Average drought frequency (yr) is seen to increase gradually from dry to wet regions, from 4 years in the regions with Ep/ Pa ≥ 2 to above 8 years in the regions with Ep/Pa ≤ 1.Read More
