The writer is thankful to the discusser for the interest in the original paper and putting forward these viewpoints. A closure to another discussion on this paper has already been published. The discusser should refer ...

Groundwater Mound due to Artificial Recharge from Rectangular Areas

Singh, Sushil K. (American Society of Civil Engineers, 2012)

The suitability of the widely used existing solution for calculating groundwater mound due to artificial recharge from rectangular areas is examined for its applicability to unconfined aquifers, and this solution has been ...

Generalized Analytical Solutions for Alternate and Sequent Depths in Rectangular Channels: Nonuniform Velocity

Singh, Sushil K. (American Society of Civil Engineers, 2013)

Novel generalized analytical solutions, in closed form, of hydraulic-energy and hydraulic-force equations governing the flow in rectangular open channels are derived considering the nonhydrostatic pressure and nonuniform ...

Generalized Analytical Solutions for Alternate and Sequent Depths in Rectangular Open Channels: Sine Form

Singh, Sushil K. (American Society of Civil Engineers, 2015)

Two novel generalized analytical solutions of nondimensional specific energy and specific force equations for flow in rectangular open channels are obtained, which enable direct and explicit calculation of the alternate ...

Simple Parametric Instantaneous Unit Hydrograph

Singh, Sushil K. (American Society of Civil Engineers, 2015)

A new, simple, parametric instantaneous unit hydrograph (IUH) with conceptual and physical justification is proposed. The new IUH has only two parameters, one of which is the time base of the unit hydrograph, an obvious ...

Analytical Solutions of Energy Equation for Rectangular Channels: Direct Approach

Singh, Sushil K. (American Society of Civil Engineers, 2017)

An analytical solution of nondimensional hydraulic energy equation is derived in cosine form for the flow in rectangular open channels considering nonhydrostatic pressure and nonuniform velocity distributions across flow ...

Analysis of rainfall and temperature trends in northeast India

Jain, S. K.; Kumar, Vijay; Sahariad, M. (Royal Meteorological Society, 2013)

The northeast region (NER) of India covers an area of 0.26 million km2. This region is one of the highest rainfall-receiving regions on the planet. Consequently, it has huge water and hydropower potential and analysis of ...

Environmental flows in India: towards sustainable water management

Jain, Sharad K.; Kumar, Pradeep (Taylor & Francis, 2014)

The strong wet and dry seasons of tropical monsoon hydrology in India necessitate development of storage and flow diversion schemes for utilization of water to meet various social and economic needs. However, the river ...

Assessment of environmental flow requirements for hydropower projects in India

Jain, Sharad K. (Current Science Association, 2015)

Increasing water withdrawals from many rivers of the world is leading to severe degradation in river ecosystems. Water is allocated for environmental needs so that a river can perform its natural functions. Environmental ...

Investigating parameters of two-point hedging policy for operating a storage reservoir

Jain, Sharad K. (Taylor & Francis, 2013)

In the operation of a reservoir, at times it is rational not to meet the current demands in full even though there may be enough water to do so. The idea is to save some water to avoid large future shortages. Hedging ...

Streamflow data-sharing policy for the Ganga Basin

Jain, Sharad K. (Current Science Association in collaboration with the Indian Academy of Sciences (India), 2013)

Hilly regions of Uttarakhand, Himachal Pradesh and Uttar Pradesh witnessed a spell of widespread torrential rainfall from 15 to 17 June 2013. India Meteorological Department (IMD) had predicted on 14 June that rainfall ...

Calibration of a catchment model using the ROPE Algorithm

Singh, Shailesh Kumar; Jain, Sharad K.; Bardossy, Andras (Elsevier, 2013)

Results from hydrological modelling are used for many watershed development activities. Hydrological cycle are same everywhere but behaviour of watershed in differenr regions of this world is different and hence hydrological ...

Validation of a new meteorological forcing data in analysis of spatial and temporal variability of precipitation in India

Li, Lu; Xu, Chong-Yu; Zhang, Zengxin; Jain, Sharad K. (Springer, 2013)

During the past two decades, numerous datasets have been developed for global/regional hydrological assessment and modeling, but these datasets often show differences in their spatial and temporal distributions ...

Erratum to: Validation of a new meteorological forcing data in analysis of spatial and temporal variability of precipitation in India

Li, Lu; Xu, Chong-Yu; Zhang, Zengxin; Jain, Sharad K. (Springer-Verlag, 2014)

The figure caption for Fig. 1 is updated. Please find here the figure with updated caption.

Reviving the Ganges Water Machine: Accelerating surface water and groundwater interactions in the Ramganga sub-basin

Surinaidu, Lagudu; Muthuwatta, Lal; Amarasinghe, Upali A.; Jain, S. K.; Ghosh, N. C.; Kumar, Sudhir; Singh, Surjeet (Elsevier, 2016)

Reviving the Ganges Water Machine (GWM), coined 40 years ago, is the most opportune solution for mitigating the impacts of recurrent droughts and floods in the Ganges River Basin in South Asia. GWM create subsurface ...

Reviving the GangesWater Machine: potential

Amarasinghe, Upali A.; Muthuwatta, Lal; Surinaidu, Lagudu; Anand, Sumit; Jain, Sharad K. (Copernicus publications on behalf of the European Geosciences Union, 2016)

The Ganges River basin faces severe water challenges related to a mismatch between supply and demand. Although the basin has abundant surface water and groundwater resources, the seasonal monsoon causes a mismatch between ...

Reference Climate and Water Data Networks for India

Jain, Sharad K. (ASCE, 2015)

The fifth assessment report of IPCC (2013) categorically states that “warming of the climate system is unequivocal, and since the 1950s, many of the observed changes are unprecedented over decades to millennia. The ...
