Daily values of discharge and sediment loads were measured and estimated at U.S. Geological Survey gaging station 12046260, on the Elwha River at the diversion near Port Angeles, Washington. Daily data are reported from September 15, 2011 to September 30, 2016. Specific data include (1) date; (2) discharge; (3) suspended-sediment concentration and one standard-deviation bounds; (4) percentage of fine-grained particles (silts and clays) in suspension; (5) loads of total suspended-sediment, fine-grained particles in suspension, and sand in suspension; (6) gauged bedload for particles between 2-16 mm and greater than 16 mm; and (7) estimated bedload for particles smaller than 2 mm.

A numerical model was developed using MODFLOW-NWT and FloPy to simulate groundwater flow and demonstrate a practical method for incorporating repeat microgravity observations (i.e., small changes in the acceleration due to Earth’s gravity) as a new type of calibration target for groundwater-flow models. The single-layer, 250-m cell size model was kept relatively simple to focus on the value of repeat microgravity data in the East Mesa area of the Imperial Valley, in the vicinity of the All American Canal, southeast California, USA. The method is demonstrated with repeat microgravity data collected over a 10-year period following the lining of the All American Canal with concrete. This lining of the canal resulted...
