Ambitious new pollution targets needed to protect Lake Erie from massive 'dead zone'（图）
dead zone pollution targets Lake Erie
2014/3/20
ANN ARBOR—Reducing the size of the Lake Erie "dead zone" to acceptable levels will require cutting nutrient pollution nearly in half in coming decades, at a time when climate change is expected to mak...
Experimental investigation on steady granular flows interacting with an obstacle down an inclined channel: study of the dead zone upstream from the obstacle. Application to interaction between dense snow avalanches and defence structures
Experimental investigation steady granular flows the dead zone upstream dense snow avalanches defence structures
2009/12/9
An experimental investigation with dry granular flows passing over an obstacle down a rough inclined channel has been performed. The aim is to improve our understanding of the interaction between dens...
Fuzzy rules based model for solute dispersion in an open channel dead zone
Fuzzy rules based model solute dispersion open channel dead zone
2009/12/4
A method has been developed to estimate turbulent dispersion based on fuzzy rules that use local transverse velocity shears to predict turbulent velocity fluctuations. Turbulence measurements of flow ...
Adaptive Fuzzy Control for Unknown Nonlinear Systems with Perturbed Dead-Zone Inputs
Adaptive control fuzzy systems dead-zone
2009/9/9
Adaptive fuzzy control is used to control a class of unknown nonlinear systems with perturbed dead-zone inputs in this paper. A new dead-zone actuator model which contains time-varying and perturbed a...
Extension of the QUASAR river water quality model to incorporate dead-zone mixing
water quality dead-zone mixing QUASAR river
2009/6/5
A modification to the well-known water quality model "Quality Simulation Along River Systems" (QUASAR) is presented, extending its utility to real-time forecasting applications such as the management ...
Longitudinal dispersion in natural channels: 3. An aggregated dead zone model applied to the River Severn, U.K.
Channels ispersion dead zones tracers
2009/3/24
An Aggregated Dead Zone (ADZ) model is presented for longitudinal dispersion of tracer in river channels, in which the channel cross-section is divided into two parallel regions: the bulk flow and dea...
