4 二水系流域及其特徵 1. (River system) (divide) (1) (Topographic divide) (2) (Groundwater divide)

5 三流域特性 1. ( ) (Planimeter) 2. (Mean elevation) (1) (Contour-length method) (2) (Grid method)

6 3. (Mean slope) (1) (2) (Horton) 4. (Length of main stream) 5. (Mean basin width) 6. (Basin perimeter) 7. (1) ( ) (2)

7 3. (1) (Horton) (2) (Strah190ler) (3) (Shreve) 4. ( ) (partial saturated areas) (Zero order stream) (valley head slope)

8 一水位 (Water level or stage) 1. (Staff gauge) 2. (1) (2)

9 二流速 (current velocity) 1. (1) (V, m/sec) (m) (sec) ( 0.85) (2) (3) 2. (1) ( ) (2)
