Description
In this paper, solar shading effects using NDVI and discharge estimation correction are considered for refinement of a stream order network model which can predict basin-wide distributions of stream temperatures. As a result, the network model is able to take into account seasonal variations of the shading effect by vegetation and also improved the accuracy of hydrological quantities in river discharge and stream width estimations. Comparison of the network model prediction with the observed stream temperatures in the Ibo River Basin in Japan showed very good agreement for the temperature distribution structures along the river network for almost all seasons, excluding an autumnal month. More considerations for higher accuracy in this month and sensitivity analyses of the model parameters are needed in the future research work.
