Abstract:
At a site ~2 km south of Hobbs Brook reservoir, Hobbs Brook converges with Stony Brook, which flows into Stony Brook reservoir, and then via an 18 km aqueduct feeds Fresh Pond in Cambridge, location of the water treatment plant. The convergence site, similar to an example provided for a stream flow measurement exercise described in Marie Morisawa's Geomorphology Laboratory Manual (John Wiley, NY, 1982), allows students to measure width, depth, and velocity to calculate discharge for the three streams. Given that precipitation in New England is fairly evenly distributed throughout the year, students must explain the flip-flop in summer and winter seasonal discharge data between Hobbs and Stony Brooks, along with the peak flows in early spring. Students can also compare their discharge data for Hobbs Brook with two remotely operated hydrographs by the City of Cambridge. Finally, students invariably find that the sum discharge of the two streams does not equal the discharge below the convergence, which also must be explained.
