Webmeasuring pollutant concentration (e.g., milligrams per liter), and calculating pollutant loads (multiplying discharge times concentration over the time frame of interest). Since concentration and flow vary with time, the key challenge in measuring loads is to determine when to sample to obtain the best estimate at least cost.

WebApr 8, 2024 · If we assume the flow weighted average SiO 2 concentration equals [SiO 2] eq, then we can solve Eq. (19) for pCO 2 in each watershed for T 0. For the parameters and assumptions utilized in this calculation, we observe that the calculated pCO 2 values increase linearly with increasing HI (R 2 = 0.38; p < 0.01; Fig. 9).
