For the prior problem, determine the location and value of the lowest DO concentration in the river and assess whether this water body is safe from eutrophication.(prior problem: An action will release DO and BOD to a large low velocity river at a location where the existing conditions of the river have already been determined. Assess the impacted conditions (as a result of this action) at a location 10,000 m down‐river from where the action releases the pollution.River:Q=2m3/s,A=1m2, T=15degC,L=5mg/L,DO=DOsat Source1: Q = 0.5 m3/s, T = 25 degC, L = 100 mg/L, DO = 1 mg/L)Please solve number 1
