In catchments adjacent to the Great Barrier Reef World Heritage Area, there is growing concern that sediments and nutrients being exported from the land are having a detrimental effect on coral reef communities. Monitoring programs have been initiated in the Burdekin catchment to determine rates of sediment runoff and to provide important base line data against which to evaluate any future effe...

Bestari Jaya, former tin mining catchment covers an area of 2656.31 hectares comprised of four hundred and forty-two different-size lakes and ponds. The present study area comprise of 92 hectares of the catchment that include four large size lakes. Arc GIS version 9.2 used to develop bathymetric map, Global Positioning System (GPS) for hydrographical survey and flow meter was utilized for water...

In low nutrient alpine lakes, the littoral zone is the most productive part of the ecosystem, and it is a biodiversity hotspot. It is not entirely clear how the scale and physical heterogeneity of surrounding catchment, its ecological composition, and larger landscape gradients work together to sustain littoral communities. A total of 113 alpine lakes from the central Pyrenees were surveyed to ...

maharlou-bakhtegan catchment in the southern part of iran is faced with water scarcity.this problem is exacerbated by environmental degradation, climate change effects, mismanagementof water resources, along with a major dependence of water demand supplies on the limitedgroundwater resources. in this study, a combined approach of dpsir model along with the scenarioanalysis was employed to deriv...

The RAIN and CLIMEX experiments at Risdalsheia, southernmost Norway, together cover 17 years (1984-2000) of whole-catchment manipulation of acid deposition and climate. A 1200 m2 roof placed over the forest canopy at KIM catchment excluded about 80% of ambient acid deposition; clean rain was sprinkled under the roof. A climate change treatment (3.7oC increase in air temperature and increase in ...

The purpose of the study was to determine the role of land use, seasonality, and hydrometeorological conditions on the relationship between stream water potassium (K+) concentration and discharge during different types of floods-short- and long-duration rainfall floods as well as snowmelt floods on frozen and thawed soils. The research was conducted in small catchments (agricultural, woodland, ...
