Water Quality Hydrology Coursework 2 Question 1: seed periodical Stimulation Model: Mass Balance for a artificial lake for each time t is: Change of depot (t) = Inflows(t) Outflows(t) Where at any time t, St+1 - St = Qt - Rt - At - Lt where 0?St ?C With, St = generator memory board book of account at time t. At t=0, S0= 14 St=1= root storage volume at time t+1. Qt = river influx during period t, its the volume of water flowing from the river into the generator. Rt = reservoir release during period t (includes environmental flows and spill). Rt= 3 mm3. At = abstraction during period t. At is 1 mm3 except from may to September when its 3 mm3. Lt = evaporation and seepage losses during period t. Lt : 2% per calendar month. C = maximum storage capacity. C = 20 mm3. The table 1 of results below shows the calculations of storage, moolah storage and spill for the following months: . * exclusively the values argon rounded up to two decimal fraction places * Equations and formulas use: 1. For Losses: 2/100 of the actual storage 2.

scratch line Storage: St+1 - St = Qt - Rt - At - Lt and function used in excel is IF(F3>20,20+B4-C4-D4-E3,F3+B4-C4-D4-E3) for each value (changing the values from a month to another) 3. Actual Storage : IF(F4>20,20,F4) because maximum storage is 20 Mm2 4. decline : IF(F4>20,F4-G4,0) which represents the difference between the Net Storage and the Storage interpret 1 repr esents the volumes of Inflow, Abstraction, R! elease, Losses, Storage, Net Storage and Spill against time: 2.a) Verifiying that the create block hydrograph is uniform with a 1 cm pelting: For a unit hydrograph of a catchment, rainfall is uniform all over an area for a period of time in this strip 10 minutes. For the habituated data: * Total time = 130 min * Total outpouring = 37.71m2 /sec * The Volume of water for...If you want to get a mount essay, order it on our website: OrderCustomPaper.com
