Phosphate transport variation in sand column
Groundwater pollution by human activities has been reported severally. Movement of leachate is identified as a major process of the phenomenon. Analytical work to replicate the process has been partially successful in soils. The objective therefore was to investigate the one dimensional (1-D) transport of phosphate at the side and centre of a sand column, verify and calibrate the model derived. Phosphate of known...

Validation of the rainfall-runoff SCS-CN model in a catchment with limited measured data in Zimbabwe
An evaluation of available opportunities to revive irrigation on a long abandoned irrigation scheme in a dry region of Zimbabwe is presented by assessing water availability at catchment level. The aim is to enhance the livelihoods, income and nutrition of the communities that depend on the irrigation scheme through a sustainable management of revitalised irrigation infrastructure and ensure food...

Hydrological assessment and suspended sediment loading of the Chini Lake catchment, Pahang, Malaysia
Hydrological evaluation and sediment loading of the Chini Lake catchment was investigated. Sediment loads and water discharge from seven selected feeder rivers were measured over a period of one year (January to December 2006). Suspended sediment concentration was measured by the standard method. The annual rainfall from 1984 to 2006 at the Chini Lake catchment ranged from 1487.70 mm (1997) to...

Application of Geographic Information System (GIS) in sustainable groundwater development, Imo River Basin Nigeria
There is proliferation of shallow substandard private water wells, poor distribution of public water wells, poor planning, and poor management of public wells in the Imo River basin Nigeria. Over 60% of water wells developed in the basin is either abortive or not functional. To investigate this, 110 vertical electric soundings (VES), 50 down-hole logs, and 44 pumping test data have been integrated into...

Influence of Nambul River on the quality of fresh water in Loktak lake
The major and trace elements in the water samples of Loktak lake and Nambul river, the most polluted river draining into the lake were determined by using Energy Dispersive X-ray Fluorescence (EDXRF) technique. The physico-chemical parameters as well as the concentration of trace elements so far detected were compared with that of WHO limits for both cases and a comparative study were done to investigate the...

A study of physico-chemical characteristics of three fresh water springs of Kashmir Himalaya, India
The present study was carried out on the physico-chemical analysis of three fresh water springs in district Pulwama of Kashmir Valley viz: Sandyasar naag (Ladhu), Batenaag (Khrew) and Sonaraaz naag (Shar).The samples were collected on monthly basis from January to June 2011. The various parameters were analyzed after APHA (1992) and Gupta (2004). The determined values of the three springs depicted slight...

Neotectonic belts, remote sensing and groundwater potentials in the Eastern Cape Province, South Africa
The Eastern Cape Province is surrounded by three major neotectonic belts (south, east and north). Each one of these neotectonic belts has its own particularities. This study aims at characterizing and targeting potentially high yield aquifers in the neotectonic zones in the Eastern Cape Province. The methods used in this study include a comprehensive literature review, examination of digital elevation models and...

Satellite remote sensing and geographic information systems (GIS) to assess changes in the water level in the Duhok dam
The use of satellite remote sensing (RS) has salient progress in water budget calculation and it performs in watershed management. An RS technique can properly enhance hydrogeologic surveys. Moreover, to have an intimate understanding of the changes in water level fluctuations, it is also important to relate them to the surrounding eomorphic, structural, climatic and geologic factors. This research serves...
