A spatially distributed analysis of erosion susceptibility and sediment yield in a river basin by means of geomorphic parameters and regression relationships
Papers published in Hydrology and Earth System Sciences Discussions are under open-access review for the journal Hydrology and Earth System Sciences Abstract In the present work, an application of statistical regression relationships utilising ge-omorphic parameters is attempted in a spatially distributed mode, in order to predict the amount of river sediment supply at varying sections of the d...
متن کاملSediment yield mapping in a large river basin: the Upper Yangtze, China
A number of studies have mapped sediment yield at global or regional scales using sediment load measurements from rivers. However, the suitability of the limited mapping methods has not been fully addressed, particularly for large river basins where the sediment load data were obtained from a hierarchical river network. This study examines some of the issues related to the mapping approaches us...
متن کاملANN-based sediment yield models for Vamsadhara river basin (India)
Most universally accepted feed-forward error back-propagation artificial neural network models, supported by batchand pattern-learning, daily, weekly, ten-daily and monthly sediment yield were developed for the Vamsadhara River basin of India. The fast gradient descent optimisation technique improved with variable learning rate (α) and momentum term (β) was used for optimisation. In the process...

متن کاملGeographic information system and process-based modeling of soil erosion and sediment yield in agricultural watershed
BACKGROUND AND OBJECTIVES: The study explored the capability of the geographic information system interface for the water erosion prediction project, a process-based model, to predict and visualize the specific location of soil erosion and sediment yield from the agricultural watershed of Taganibong. METHODS: The method involved the preparation of the fou...
