Have a shallow open reactngular channel of 6 m width and 2000 m long.Flat bottom but step down of 4 cm after every 500,1000 & 1500 m along channel. Lateral inflow of 0.006 M3/s at each step down. Manning coefficient is 0.0012 and wind velocity opposite to water flow is 5 m/s. Initial flow rate is 0.06 m3/s and water depth of 0.1m

Need know water depth w.r.t. time and space?
