Changes in Rainfall Characteristics at Huai Kog-Ma Watershed, Chiang Mai Province

Rainfall characteristics in term of number of storms, number of rainy days, amount, duration, intensity and 30 minute maximum intensity were investigated from 3 tipping bucket automatic recording raingage located at Huai Kog-Ma Watershed, Chiang Mai Province during 1997-2013. Non-parametric and parametric test were employed to detect rainfall characteristics trends. The results reveal that mean annual rainfall of Huai Kog-Ma ... Read More »

Mathematical Models for Estimating Evapotranspiration of a Hill Evergreen Forest in Kog Ma Watershed, Doi Pui, Chiang Mai Province; 1. Model Formulation, Calibration and Verification

An application of a mathematical model was studied coupling the Penman, Penman-Monteith and Rutter’s models to estimate the evapotranspiration of a hill evergreen forest at Huai Kog Ma, Doipui, Chiang Mai province, northern Thailand.  The results obtained from the coupled model were compared with those measured from the Eddy-Correlation method.  To calibrate and verify the results from the model, Nash ...
