ASSIGNMENTS

No. DescriptionAssigned Due
 
01 Choose one of the the types of hydrology listed in Facets and write a short essay (100-200 words) on it. 220822 220829
02 Calculate the psychrometric constant γ at an elevation of 2,000 m above mean sea level and air temperature T = 15°C at 0% relative humidity. 220907 220914
03 Write a short essay (200 words or less) explaining why the runoff curve number method is effectively a surface runoff curve number method. How does this affect, or limit, the applicability of the method? 220912 220919
04 What is the main conceptual difference between the runoff curve number method and Horton's infiltration formula? 220914 220921
05 (a) Derive Eq. 2-51 of D1 of the Syllabus. (b) How do we know for sure that the kinematic wave produces the fastest response in overland flow dynamics? Explain in a less-than-200-word statement. 220921 220928
06 Can the local (and eventually, regional) climate be subject to change by anthropogenic vegetation/ecosystem management? What is the controlling factor? Explain in a less-than-200-word statement. 220928 221005
07 Prove Eq. 11-40 in item F07 of the Syllabus. 221019 221026
08 What was Creager's contribution to flood hydrology? How does it relate to runoff diffusion? Describe in a less-than-200-word statement. 221026 221102
09 Explain the difference between Clark's original unit hydrograph (1945) and Ponce's version (1989). Which version results in a lesser peak? Why? 221102 221109
10 Prove that Eqs. 10-10 and 10-11 in item G13 of the Syllabus are equivalent. 221107 221114
11 Explain the difference between kinematic, diffusion, and dynamic waves. What is grid independence in the context of numerical modeling? What flood routing method is demonstrably grid independent? Why? 221114 221121
12 Explain why the solution of the St. Venant equations, commonly referred to as the "dynamic wave", requires a knowledge of a looped downstream rating curve for the solution to be consistent with the differential equation. How may this difficulty be resolved in practice? Why is it commonly not done? 221121 221128
