Mapping groundwater potential in Kitui District, Kenya using geospatial technologies

January 2011

  Kitui district is a semi-arid region characterized by erratic and unreliable rainfall. Despite this, the main economic activity is rain-fed agriculture, with irrigation agriculture taking place on small parcels adjoining riparian reserves. During the dry season, local people travel long distances in search of water, necessitating groundwater potential mapping to support exploitation and complementing other...

Water resources management and sustainable development in Sudan

December 2010

  For the thirty-nine million who live in Sudan, environmental pollution is a major concern; therefore industry, communities, local authorities and central government, to deal with pollution issues, should adopt an integrated approach. Most polluters pay little or no attention to the control and proper management of polluting effluents. This may be due to a lack of enforceable legislation and/or the fear of...

Environmental flows in Bhadra River, Karnataka, India

November 2010

  Environmental water requirements, also referred as ‘environmental flows’, are a compromise between water resources development and the maintenance of a river in ecologically acceptable or agreed condition. Managing environmental water flow is a complex task because the change of quantity of water occurs as the flow moves downstream. In this work, an attempt has been made to evaluate the...

Need of benchmarking for socially and environmentally sustainable development of a major irrigation scheme

November 2010

  It is a proven fact that the quantity and quality of available water resources have been recognized as limiting factors in development of most of the arid and semi arid regions. The function of the conveyance and distribution systems and services should be providing sufficient water in a timely manner so that it can be used efficiently for crop production. Reliability, flexibility and efficiency are the...

The diurnal variation of the physico-chemical parameters of a lowland river flow in a semi-arid landscape with human interferences in Zimbabwe

September 2010

Using data from southeast Zimbabwe intensive agricultural zone we investigated diurnal changes in the Runde River to discover the variations that can occur in the control and test sites of agricultural development. This should predict how the aquatic ecosystem responds when ’stressed' by human activities, such as runoff from the land. Diurnal changes were studied at a resolution of 2 h intervals between 0500...

A methodology of finding dispersion coefficient using computational fluid dynamics (CFDs)

July 2010

  The treatment efficiency of waste stabilization pond is directly related to its hydraulic regime. The hydraulic efficiency of the pond is dependent on parameters such as the pond geometry, the location of inlet and outlet and the inlet flow velocity. Poorly designed or specified hydraulic parameters may lead to short circuiting and dead regions within the pond. This in turn impacts the dispersion coefficient....

Prioritization of micro watersheds on the basis of soil erosion hazard using remote sensing and geographic information system

July 2010

  Degradation of agricultural land by soil erosion is world wide phenomenon leading to loss of nutrient-rich surface soil, increased run off from more impermeable subsoil and decreased water availability to plant. Thus estimation of soil loss and identification of critical area for implementation of best management practice is central to success of soil conservation programme. In this study universal soil loss...

Making a case for systems thinking approach to integrated water resources management (IWRM)

July 2010

  While definite benefits could be gained from integrating the management of natural and human systems, taking into account the effects of human activities on the environment, the task of operationalising and implementing this approach in practice represents an enormous challenge. Some limitations highlighted include the definition of integrated water resources management (IWRM) itself, where it appears to be...

Modeling hydropower plant system to improve its reservoir operation

June 2010

  One way of improving water management is increasing the efficiency of utilization of dam reservoirs. Even small improvement in reservoir operation can lead to large benefits. But there is no universal solution for reservoir operation problems. Hence, it is necessary to study the system and determine optimal reservoir operation guides for each scheme. In the present study, Melka Wakana Hydropower Plant in...
