Determination of rainfall-recharge relationship in River Ona basin using soil moisture balance and water fluctuation methods
A quantitative evaluation of spatial and temporal distribution of groundwater recharge is a pre-requisite for the management of ground water resources system in an optimal manner. The amount of groundwater recharge depends upon the rate and duration of rainfall, as rainfall is the principal means for replenishment of moisture in the soil water system and recharge to ground water. This paper investigated the relationship...

Hydro and solar-pond-chimney power scheme for Qattara Depression, Egypt
This study summarizes previous proposals and studies concerning Qattara power projects and gives some details about a new concept, which aims to produce hydropower like all previous proposals, and also extra electric power and fresh water via a site specific solar-pond-chimney system. Sea water from the Mediterranean Sea and re-used water from the end of Rosetta branch would feed an artificial lake in the Qattara...

Groundwater conditions and hydrogeochemistry of the shallow Benin Formation aquifer in the vicinity of Abraka, Nigeria
Shallow borehole and dug well data are used in describing groundwater conditions in the vicinity of Abraka in the Nigerian coastal plain. Drill cuttings from ten boreholes show that the Abraka area is underlain by reddish brown unconsolidated sands, followed by a succession of grey- off-white medium grained sands of the Benin Formation. Hydraulic conductivity estimated from grain size analysis of cuttings obtained from...

Strategies and techniques of providing adequate and affordable potable water in rural areas of Nigeria
Water is next to air in importance. The World Bank declared water as an economic good while endorsing the international demand for water supply. Human health depends on having access to safe, adequate and reliable water supply. In Africa, and of course in Nigeria, one half of the entire continent’s people (particularly in rural areas/communities), suffer from one or more of the six main diseases associated with...

Integrated water resources management in Iran: Environmental, socio-economic and political review of drought in Lake Urmia
In recent years Lake Urmia, the largest saline lake in the Middle East located in northwestern Iran has undergone severe environmental changes. As a result of drought and anthropogenic impacts, the area of the Lake has been shrunk and the water level has been dropped. In this article the environmental, political and socio-economic impacts of drought in Lake Urmia basin has been reviewed and the obstacles regarding...

Assessment of discharge and sediment transport from different forest cover types in lower Himalaya using Soil and Water Assessment Tool (SWAT)
The present study was carried out to examine the applicability of Soil and Water Assessment Tool (SWAT) in estimating daily discharge and sediment delivery from mountainous forested watersheds and to assess the impact of forest cover types on stream discharge pattern and sediment load. The study watersheds namely Arnigad and Bansigad, comprising of dense Oak forest (80%) and degraded Oak forest (83%) respectively, are...
