  • MATHEMATICAL MODELLING OF GROUNDWATER SYSTEM 
    Kashya, Deepak (1981)
    Mathematical models of groundwater system have become an important compontnt of water resources planning. These models assist the planners in arriving at optimal ground water development policies either by studying large ...
  • OPTIMAL DESIGN OF BARRAGE ON PERMEABLE FOUNDATION 
    Kumar, Devendra (1982)
    In irrigation engineering barrage is the most exten sively used hydraulic structure for diversion of river flow. A barrage founded on porous medium is designed for surface and sub-surface flow conditions. For given ...
  • FLOW TO A WELL IN MULTIPLE AQUIFER SYSTEM 
    Nautiyal, M.D. (1984)
    Water wells generally tap more than one aquifer. The mathematical solutions developed so far for determining drawdown and individual aquifer's contribution during the unsteady state flow to a multiaquifer well are ...
  • HYDROLOGICAL RESPONSE OF UNSATURATED ZONE UPTO WATER TABLE 
    Rao, K.M. Mohan (1986)
    The rainfall and applied irrigation exoite the unsatura ted zone, extending from ground surface upto the water table,at the ground surface. The hydrological response to this excitation comprises amongst others, the ...
  • A STUDY OF UNCONFINED SEEPAGE FROM PARALLEL CANALS 
    Bhargava, D.N. (1988)
    Irrigation canals are generally constructed in a deep pervious alluvium and are largely unlined. These canals alongwith their conveyance system are a major source of seepage from them which recharges the aquifer. The ...
  • SURFACE RUNOFF MODELLING OF AN ALKALI WATERSHED UNDER RECLAMATION 
    Thapa, Khadga Bahadur (1988)
    In India and also in many parts of the world, vast tracts of waste-lands are due to alkalinity of the soils. An alkali soil contains sufficient exchange able sodium, which causes the soil to disperse and to increase ...
  • CAPACITY EXPANSION OF A WATER RESOURCES SYSTEM 
    Waikar, M. L. (1989)
    Comprehensive river basin water resources planning is a complex and very difficult task posing numerous social, economic, environmental, and engineering problems. While planning for the development of a big river basin ...
  • APPLICATION OF KINEMATIC WAVE THEORY TO SMALL WATERSHEDS 
    Hossain, Md. Mubarak (1989)
    tn the recent past, in many developing tropical countries a good deal of research has been carried out to solve the problems of 'large basins' whereas not much has been done with regard to the hydrologic problems of small ...
  • INVESTIGATIONS OF CHARACTERISTICS OF BIOGAS GENERATION USING BIOMASS WASTES 
    Sharma, Sudhir K. (1989)
    The vast majority of rural people in the developing and under-developed nations, which make together around half of the world's population, are totally dependent on biomass for their fuel requirements. On the basis of ...
  • MODELLING FOR FLOOD FLOWS 
    Goel, Narendra Kumar (1990)
    Since time immemorial floods have been causing loss of human lives, valuable property and crops in most parts of the world and India is no exception to this. The flood damage can be reduced significantly by proper ...
  • MODELLING OF SOLUTE TRANSPORT THROUGH AN UNSATURATED ZONE EXTENDING FROM GROUND SURFACE TO WATER TABLE 
    Gupta, Sulekha (1991)
    Waste disposal on land and application of fertilizers and pesticides to crop lands has become a common practice universally. Water infiltrating at the ground, dissolves such matter and carries it downward through the ...
  • A STUDY ON SALTWATER TRANSPORT TOWARDS A PUMPING WELL 
    Shalabey, Mostafa Eleraky Ealsayed (1991)
    The available analytical solutions for upconing of saltwater interface are based upon many restrictive assumptions which may not always be satisfied. In the present study, an attempt has been made to develop a numerical ...
  • NUMERICAL MODELLING OF TWO-DIMENSIONAL TRANSIENT SUBSURFACE FLOW TO DITCHES 
    Ahmad, Saleem (1992)
    Inadequate natural subsurface drainage in an agricultural area results in a rise of water table up to the root zone of cultivated plants. This restricts the oxygen supply to the plant root system. The high water table ...
  • MODELING OF FLOOD FLOWS IN NATURAL WATERSHEDS 
    Shahri, Mohammad Reza Najafi (1993)
    In this research work an attempt has been made to develop a model having capabilities of accounting for the spatial and temporal variations of rainfall as well as of physiographic characteristics which do prevail in ...
  • SPACE TIME CHARACTERISTICS OF RAINFALL IN EAST RAJASTHAN 
    Sastri, Kota Sri Rama (1993)
    Rainfall in semi arid regions is low and uncertain. For long term planning of water resources development and short term planning for agricultural operations it is essential to understand the mechanisms and behaviour ...
  • SYSTEMS ANALYSIS OF A COMPLEX WATER RESOURCES SYSTEM 
    Sadeghian, Mohammad Sadegh (1995)
    Basin resources planning has become an increasingly important concept in comprehensive planning of a complex water resources system. Comprehensive basin water resources planning is a complex and a difficult task, posing ...
  • AN INTEGRATED HYDROGEOLOGICAL STUDY OF MAHENDRAGARH DISTRICT, HARYANA, INDIA 
    Tizro, Abdullah Taheri (1995)
    Mahendragarh district, Haryana, located near its border with Rajasthan, is a semi-arid area and affected almost perennially by scarcity of water. The average yearly rainfall for the Mahendragarh raingauge station, recorded ...
  • INTEGRATED PLANNING AND OPERATION OF A RESERVOIR 
    Kohistani, Assadullah (1995)
    Isolated studies on various aspects of planning/operation of a reservoir have been carried out and presented in various studies, using systems analysis techniques. A few studies on combined planning and operation of a ...
  • HYDROLOGICAL STUDIES OF DISTURBED MOUNTAINOUS WATERSHEDS
