However, this target is still far from being achieved. In 2009 the average domestic water tariff in Malaysia was Ringgit (MYR) 0.65/m3 (US$0.18/m3). There are 14 different regional water tariffs in Malaysia, each corresponding roughly to one state. The lowest domestic tariff is in Penang (MYR0.31/m3), while the highest is in Johor (MYR0.98/m3).
The topographic wetness index (TWI), also known as the compound topographic index (CTI), is a steady state wetness index. It is commonly used to quantify topographic control on hydrological processes. [1] The index is a function of both the slope and the upstream contributing area per unit width orthogonal to the flow direction.
Peninsular Malaysia experienced unusually hot and dry weather in early 2014, with a lack of rainfall in key catchment areas from which the water supply was sourced. [1] Early speculations linked the dry weather to the El Niño effect, but no El Niño emerged in 2014.
The National Water Quality Inventory Report to Congress is a general report on water quality, providing overall information about the number of miles of streams and rivers and their aggregate condition. [65] The CWA requires states to adopt standards for each of the possible designated uses that they assign to their waters.
Despite its growing importance, the issue of water quality has long been nearly absent from water coverage assessments, since few countries could afford regular water quality surveillance. Instead, it is assumed that certain types of water sources categorized as 'improved' are likely to deliver drinking water of adequate quality for basic ...
Drinking water quality standards describes the quality parameters set for drinking water. Water may contain many harmful constituents, yet there are no universally recognized and accepted international standards for drinking water. Even where standards do exist, the permitted concentration of individual constituents may vary by as much as ten ...
Diagenesis (/ ˌ d aɪ. ə ˈ dʒ ɛ n ə s ɪ s /) is the process of physical and chemical changes in sediments first caused by water-rock interactions, microbial activity, and compaction after their deposition. Increased pressure and temperature only start to play a role as sediments become buried much deeper in the Earth's crust. [1]
