Water quality modeling helps people understand the eminence of water quality issues and models provide evidence for policy makers to make decisions in order to properly mitigate water. [1] Water quality modeling also helps determine correlations to constituent sources and water quality along with identifying information gaps. [2] Due to the ...
The earliest examples of irrigation works in Sri Lanka date from about 430 BCE, during the reign of King Pandukabhaya, and were under continuous development for the next thousand years. In addition to constructing underground canals , the Sinhalese were the first to build completely artificial reservoirs to store water , referred to as tanks ...

Dry ponds temporarily store water after a storm, but eventually empties out at a controlled rate to a downstream water body. Sand filters generally control runoff water quality, providing very limited flow rate control. [20] A typical sand filter system consists of two or three chambers or basins.
Some districts of Sri Lanka have epidemic rates of Chronic Kidney Disease of Unknown Etiology (CKDu). [29] Pollution of groundwater by chemical-agricultural runoff is a suspected factor; men are more likely than women to develop the condition. [29] Kidney disease rates are highest in areas that use water diverted from the Mahaweli River. [32]
In fluid dynamics, pipe network analysis is the analysis of the fluid flow through a hydraulics network, containing several or many interconnected branches. The aim is to determine the flow rates and pressure drops in the individual sections of the network. This is a common problem in hydraulic design.
The Mahaweli Development program (Sinhala: මහවැලි සංවර්ධන වැඩසටහන) is known as the largest multipurpose national development program in the history of Sri Lanka and is also considered the keystone of the government's development program that was initiated in 1961.
In 2000, only 25% of the households in Sri Lanka got their water through pipes. Even the water that does come through the pipe from local suppliers is not monitored efficiently. This is why a part of the population does not get clean drinking water. [2] Sri Lanka's wastewater management requires a lot of work.
