Variation of Dissolved Material Concentration during Storm Event in a Small Watershed
Abstract
In the analysis of dissolved material concentration - discharge relationship, the use of the dilution model is common. The dilution model explaining the solute transport is usually based on data derived from various samples which are characterized by low frequency of sampling. The range of frequencies covers infrequent samples on a monthly, weekly or daily basis. Therefore, the usual rating curve of dissolved material concentration - discharge relationship ignores the condition of flow (rising or falling stage, low or high base flow) at the time of sampling. Data from recent higher frequency events raises a question as to whether the simple model is suitable for explaining solute transportation during storm events.References
