For transport purposes sediments are principally characterized by their size, by constituent composition, and by cohesion. 0000162058 00000 n �ҡ����z�u�C ��rk׭ �HE$���|բ�_��d��/��0��չ^��Z���u�����d�h�Vߘǚh-ϭ�d8DT��F c���8Ϻ�d.f��v�X �>�S�2ѯ�����?�q^���8�^�g��v[t]��~�pjE��rY}wG���4b�8�u~Pd�D�఼�p7>���A"�F���p �b� 0000158589 00000 n 1.

Bed-load transport takes place in the area near the bottom and is therefore a very important factor in the shaping of the river bed. The key variable governing the sediment weight is grain size D. �5TI�d\ifx�¹3?��,��1�p��z��6�ѺN��oS9�!J/�3�n��&�'ӷ�������j�F�-�F�k�� Therefore, FT distribution pattern and sediment where g is the acceleration from gravity (9.81 m s21), s is the transport are valid and representative of local field conditions. Lecture Notes - Sediment Transport – The Sediment Problem At the end of the first lecture, we noted that our steep, nonlinear transport model depended on τ*, which is the ratio of the bed shear stress τ to the weight of the sediment grains per unit bed area. �c�G���Vfs�sa�1Qծ�#P�R�}���+ �MM�� ��X�Gn���I]A��f�G��J®?�*69�S�����ͅ����Gj�ByҤM �J���� bj,����'�YS���+�Ɗ`��� Q�C����oW$Wsw+?�[]P���f< ���E.
