Studying on water quality of Dai Lai reservoir by one year of field investigation and data collection

Abstract

    Water eutrophication is a type of decreasing water quality, which is often happened to the lake and reservoir water. It is a process of enrichment of nutrient to lake water (mainly from nitrogen and photphorus components) causing boomming of water plants (periphyton, algae, macrophytes, water hyacinth...). As a result, suspended substance, organic matter were increasing thus decreasing water quality and make difficulties for economy development.

    Observation results from Dai Lai reservoir release that water quality of the reservoir is quite good; the reservoir water is not eutrophic by phophorus, disolved oxygen of water is high and satisfied the level for dometic use of Vietnamese standards level. Nitrogen concentration of the water is quite high. The observed data will be uesd as input parameter to test a built software at next step.
