Correct Estimation

Abstract Suspended sediment load (SSL) time series have three principal inherent components (autoregressive trend, seasonality and stochastic terms) and the overall performance of an SSL modeling tool is associated with the correct estimation of these components. In this study, novel developments of artificial neural network (ANN) models, emotional ANN (EANN) and hybrid wavelet-EANN (WEANN), are employed to estimate the daily and monthly SSL of two rivers (Upper Rio Grande and Lighvanchai) with different hydro-geomorphological conditions. The overall results obtained via autoregressive models, the ANN and EANN, specify the supremacy of EANN (with a few hormonal parameters) against ANN due to the EANN better training the model versus extreme conditions. Also, the obtained results exhibit that the WEANN model could improve the SSL modeling up to 42% and 14% for daily modeling and up to 141% and 87% for monthly modeling in the Upper Rio Grande and Lighvanchai Rivers, respectively.

Point Type

Paleoindian occupations across the Southwest are known largely from surface artifact collections because relatively few in situ sites are known. Clovis is the exception, with one of the world’s highest concentrations of Clovis mammoth kills occurring in southeast Arizona (Murray Springs, Naco, and Lehner). Otherwise Clovis is thinly scattered across New Mexico, Chihuahua, and Sonora. Folsom is the most common Paleoindian projectile point type in the Southwest in terms of numbers, but is largely concentrated in the basins of the Upper Rio Grande valley in New Mexico and Colorado. Unfluted Paleoindian artifact styles are widely scattered throughout the region, but most are concentrated along the Upper Rio Grande valley.
