Flow computation in Saptamukhi river estuary of Sunderbans delta in West Bengal using finite element method – A research report by National Institute of Hydrology

The study deals with flow computation in Saptamukhi river estuary in Sunderbans delta of West Bengal using finite element method. Complex interactions between physical, chemical and biological processes are present in coastal areas. Water circulation is one of the most important factors controlling these processes. The study of the real hydrodynamic regime and proper management of estuaries, lagoons and coastal regions due to high tides, peak flows erosion, sedimentation and pollutant load discharges is vital.Read More

Evaluation of groundwater table and quality in Krishna delta of Andhra Pradesh – A research report by National Institute of Hydrology

The report attempts to analyze the shallow groundwater table and water quality data for about 20 years pertaining to the Krishna delta. The trend analysis of groundwater level data of shallow wells indicates that in the upper part of the delta, the groundwater table moved up during the period 1979 to 1999. This may be due to the dense canal network in the delta and increase in irrigated area over a period of time.Read More

Estimation of rainfall recharge in a coastal area through inverse groundwater modeling - A research report by National Institute of Hydrology

The study focuses attention on the use of inverse modeling technique for estimation of rainfall-recharge in a coastal aquifer. MODINV (Modular Inverse Model), which is software for parameter optimization of 3-D groundwater flow model, MODFLOW is applied to the Central Godavari delta in Andhra Pradesh to estimate the distributed rainfall-recharge during monsoon season.Read More

A study of saline freshwater interface phenomena in the Mahanadi delta region (Orissa)

A study of saline freshwater interface phenomena 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, both of which are prone to saline water mixing/migration with time and development:Read More

  • 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.
  • The north eastern parts of Mahanadi delta is represented by deep freshwater confined aquifers overlained by brackish/saline water aquifers with aquitard/ aquiclude boundary.

Baseflow studies for three rivers between Mahanadi and Godavari deltas - A research report by National Institute of Hydrology

The study suggests a procedure based on the methodology of Gustard et al (1992) for estimation of baseflow index (BFI) using the mean daily discharge data over a period of 4 to 6 years for three rivers between the Mahanadi and Godavari deltas. The rivers from the Zone 4 (A) are Rushikuliya at Purushottampur in Orissa, Nagavalli at Narayanpuram wier and Sarada at Anakapalli in Andhra Pradesh.Read More
