3.Watershed-it is the total area of a region which contribute to the same outlet runoff or the entire geographical area drained by river and its tributaries. The flow stream will be contributed from highest elevation point of the region to the outlet runoff. 4 .A grab sample is a sampling technique which is a single sample or measurement taken at a specific time or over a short period as feasible. Grab sample provides an immediate sample and are thus preferred for some tests. It is also known as catch sample or individual sample. Composite sample is sample whereby multiple samples are combined, thoroughly homogenised and treated as single sample. 5.Alkalinity-it refers to capability of water to neutralise acid. The alkalinity can be due to presence of carbonate, bicarbonate and hydroxides etc in the solution. Alkalinity is important for fish and aquatic life because it protects or buffer against rapid Ph change. Also alkalinity neutralises acidity in our body which is root cause of inflammation or disease in the body.
