Jp. Syvitski et al., HYDROTREND - A CLIMATE-DRIVEN HYDROLOGIC-TRANSPORT MODEL FOR PREDICTING DISCHARGE AND SEDIMENT LOAD TO LAKES OR OCEANS, Computers & geosciences, 24(1), 1998, pp. 51-68
HYDROTREND is an ANSI-standard FORTRAN-77 numerical model that creates
synthetic river discharge time series as a function of climate trends
. As a drainage basin simulator, the model provides simulation of dail
y discharge hydraulics at a river mouth, including the sediment load p
roperties. Model outputs may provide direct input to lake or shelf cir
culation and sedimentation models. HYDROTREND accepts direct input fro
m meteorological station data or global circulation model output (mont
hly statistics of temperature, precipitation and evaporation and their
interannual variations), and input of basin characteristics (attitudi
nal temperature gradients, topography, glacier equilibrium line altitu
des, and sediment transport and erosion coefficients). HYDROTREND appl
ied to the temperate Eel River drainage basin provides a test of the m
odel's handling of rare hood events brought on decadal, centennial or
longer climatic events. The USGS observations on the Eel River include
the decadal storms and the 400 y-return 1964 flood event. HYDROTREND
captures the range in magnitude and return interval of peak discharge
events and their sediment loads. (C) 1998 Elsevier Science Ltd. All ri
