Abstract
Sediment graph (SG)
is a graphical presentation of sediment fluxes with respect to time. The SG
facilitates hydraulic structure designers, planners and decision makers to have
a proper and sound idea about the temporal variation as well as total amount of
sediment yield passing from a control point. The effective and compatible
design of hydraulic structures and management can be therefore made using the
accurate evaluation of sediment yield obtained through applying SGs. There are several ways viz. continuous sediment
sampling, unit SG, conceptual approaches and empirical models to gain SG out of
which models based on accessible discharge data as well as watershed physical
characteristics are more applicable in countries where lack of sediment data exist. In the present paper, an attempt has been therefore made to
present some techniques for development of SGs two of
which have been satisfactorily applied to the Khanmirza
watershed in
