Good day, I am John Harold Cruz, a graduating student of BS Civil Engineering at the University of the Philippines Diliman. I would like to request some meteorological information necessary for my research entitled: "Numerical Investigation on the Effect of the Sediment Yield of Marikina River Basin to Flood Hazard Parameters at Barangay Tumana, Marikina City under Changing Climate Conditions." The following are the data needed for establishing my hydrologic model: 1. Baseline, 25-year, 50-year, and 100-year Rainfall Return Periods on Subbasins of Marikina River Basin 2. Climate Change Projection of each rainfall return period for the year 2050 3. Recorded Rainfall Data for Years 2020-2024 for Model Calibration I am also open for further discussion regarding my request. Thank you so much for your consideration.
