The annual storage in broad river watershed is 0 cm/y. annual precipitation is 100 cm/y and evapotranspiration is 50 cm/y. the sandy loam soil in the watershed has an infiltration rate of 5 × 10-7 cm/s. the area of the watershed is 40 km2. calculate the annual flow at the outlet of broad river. what is the runoff coefficient for this watershed?

Afoot bridge is made as a simple deck, 4 m long, with a cross section 2 m (wide) and 20 cm thick, and made of wood. the deck is supported at the two ends. the maximum load allowable on the bridge is 10 tons, provided it is uniformly distributed on the deck. to sense this load, a strain gauge is placed at the center of the bridge and its resistance is monitored. if the sensor has a nominal resistance of 350 s2 and a gauge factor of 3.6, what is the reading of the strain gauge at maximum load? the modulus of elasticity for the wood used in the construction is 10 gpa.
