• 1-Flood Estimation in India using regional frequency analysis 

  Seth, S. M.; Singh, R. D. (National Institute of Hydrology, 1987)

  The use of regional flood frequency approach provides one of the most effective ways for the estimation of design floods at ungauged sites. Many distributions such as Gumbel ...
• 2-Regional flood frequency approach estimation of flood peaks for Mahi and Sabarmati basin (sub-Zone 3a) 

  Gupta, P. N. (National Institute of Hydrology, 1987)

  Knowledge of magnitude of flood related to its problem frequency of recurrence is necessary for rational and economical design of water-way and foundations of bridges and appurtenances. In this Paper ...
• 3-An alternative statistical regional approach for estimating design flood peak. 

  Thirumalai, S.; Sinha, P. B. (National Institute of Hydrology, 1987)

  Regional flood frequency studies are often made following traditional approach viz, a formula for mean annual flood and growth factors for higher return periods based on individual station values. This approach ...
• 4-Weighted ordinary least square algorithm for batch processing. 

  Khosa, Rakesh (National Institute of Hydrology, 1987)

  A deconvolution algorithm for a linear system with finite memory is developed using exponential weighting. The algorithm is developed with the idea of using it in batch mode. The solution derived is ...
• 5-A comparative analysis of hydrological and diffusion methods of flood routing. 

  Rangapathy, V.; Karmegam, M.; Sakthivadivel, R.; John, V. K.; Lekha, P. Mathai (National Institute of Hydrology, 1987)

  As a part of the study of flood routing methods as applicable to Indian rivers, an attempt was made to apply the Conventional Muskingum method, the Constant and Variable Parameter Muskingum Cunge ...
• 6-Development of dimensionless hydrographs from Machhu Dam-II failure using DAMBRK model. 

  Santoshi, M. K. (National Institute of Hydrology, 1987)

  This paper presents a methodology for the quick estimation of dam break flood wave and its characteristics such as peak flows, peak stages and their respective timings at the dam site and at specified locations ...
• 7-Design of flood embankments of Katjuri river at Cuttack city. 

  Godbole, M. L. (National Institute of Hydrology, 1987)

  Cuttack city in Orissa state is situated between Katjuri and Mahanadi rivers. There was a proposal to extend the protective embankments along these rivers at the western side of the city. The effect ...
• 8-Problems of flood control. 

  Ganguly, S. S. (National Institute of Hydrology, 1987)

  Flood may be defined as a social perception associated with sudden invension of unusually high levels of water resulting in widespread destruction and distress. Floods are caused due to intense ...
• 9-A case study of unprecedented floods in the Godavari river during August 1986. 

  Pandharinath, N. (National Institute of Hydrology, 1987)

  Unprecedented historical floods were recorded in the lower reaches of the Godavari River during 13-20 August 1986. According to available records since 1881, the highest gauge level was recorded at ...
• 10-An observational study of tropics mid-latitude interactions during different seasons. 

  Singh, Ranjit (National Institute of Hydrology, 1987)

  Over Indian region when the tropical easterly troughs and the extratropical westerly troughs come closer longitudinally, they interact and amplify each other, while maintaining their distinct identities. ...
• 11-Indian droughts-quasi biennial oscillations of stratospheric winds. 

  Singh, Ranjit (National Institute of Hydrology, 1987)

  In his earlier paper klianjit Singh, 1986), the author has shown that between 1964 and 1975, there had been five occurrences of drought in India. They have coincided on four occasions with the ...
• 12-Estimation of evaporation from free water surfaces. 

  Ramasastri, K. S. (National Institute of Hydrology, 1987)

  Methods of estimating evaporation from free water surfaces are discussed. The status of Pan and lake evaporation studies carried out in India is reviewed and the procedure for the estimation of free water surface ...
• 13-Statistical method of estimate drought occurrence. 

  Reddy, P. Bhaskar; Venkataraman, P. (National Institute of Hydrology, 1987)

  Rayalaseema region of Andhra Pradesh is chronically drought prone. The climate is generally dry with very low annual rainfall. R, laseama region comprises four districts viz., ...
• 14-Drought analysis using soil moisture status. 

  Sikka, A. K.; Lohani, Vinay K. (National Institute of Hydrology, 1987)

  The .drought situation can be described by a selected set of variables depending upon the particular water user or interest. For agricultural drought particllarly the soil moisture status in the root zone can be ...
• 15-Intensification and recession of droughts in a dry farming region. 

  Prasad, Rajendra (National Institute of Hydrology, 1987)

  The Dry Farming Region of India, characterised by 40 to 100 cm annual rainfall, stretches from extreme north to the southern tip of the country and comprises of 87 districts. Rainfall is the prime ...
• 16-Stream flow analysis for hydrological drought of Krishna basin. 

  Verma, P. K.; Sikka, A. K.; Singh, R. D. (National Institute of Hydrology, 1987)

  Drought is generally viewed as the occurrence of below normal natural water availability for the place & time, To a hydrologist, it means below average content in streams, reservoirs, lakes, tanks, ground water ...
• 17-Dissolved oxygen modelling in Hindon river (U. P.) 

  Bhatia, K. K. S. (National Institute of Hydrology, 1987)

  Rivers are one of our most important natural resources, However rivers also continue to be the carriers of waste water, Those who deal in water management will have to make many critical decisions concerning the treatment ...
• 18-The Ganga water pollution and waste water supply system in Varanasi. 

  Choudhary, U. K.; Singh, G. S. (National Institute of Hydrology, 1987)

  The most vanerated and sacred river of our country the Ganges plays a major role in the recognisation of Varanasi as a spiritual centre. The city Varanasi is situated on the concave bank of the river. ...
