Sam is an environmental hydrogeoscientist and a researcher whose work focusses on modeling of watershed water storage and release dynamics. The timing characteristics of watershed water storage and release is particularly important for the assessment of fertilizer application rates in agricultural fields, nutrient loading and eutrophication dynamics in nearby streams, and the response of watersheds to climate changes. Sam employs mainly environmental tracers (e.g., stable isotopes of water) in the calibration of his models. Sam’s novel research works have been published in distinguished hydrology journals such as Water Resources Research and Hydrological Processes. He has presented his research work at many international conferences and participated in several international workshops.
Sam’s service to the profession includes serving as a reviewer for some Geoscience Journals, e.g., Journal of Hydrologic Engineering, Journal of Earth Systems Sciences and a few others.
Sam holds a BSc. (Hons) degree in Geological Engineering from the Kwame Nkrumah University of Science and Technology in Ghana. He earned his MSc. degree in Hydrogeology from the Illinois State University in the USA. His PhD degree in Geological Sciences - with a specialization in catchment transit time and water age modeling - was obtained from the University of Manitoba, Canada.
