Preparing Curve Number Map of Run-off and Investigating its Precision Using Hydrological Model (Case Study: Navdar Catchment) [PDF]

جغرافیا و پایداری محیط, 2013
Curve Number (CN) is one of the required parameters for runoff calculation using SCS method. Considering spatial variability of factors affecting this parameter, different values of CN is expected within different parts across a catchment.

Proximal Steric Shielding Unlocks High Solid‐State Luminescence in Quinoxaline‐Fused Pyrene Heteroacenes

Chemistry – A European Journal, EarlyView.
Proximal steric tuning of quinoxaline‐fused pyrene heteroacenes enables soluble derivatives that exhibit solid‐state photoluminescence quantum yields (PLQYs) up to 82%, surpassing previous benchmarks. This work reveals key structure–property relationships for next‐generation, processable organic emitters in advanced optoelectronic applications ...

Application of GIS-based SCS-CN method in West Bank catchments, Palestine

, 2010
Among the most basic challenges of hydrology are the prediction and quantification of catchment surface runoff. The runoff curve number (CN) is a key factor in determining runoff in the SCS (Soil Conservation Service) based hydrologic modeling method ...

Two‐Coordinate 13‐Electron PdI Complexes Stabilized by the Bulky DIMeIHeptCl NHC Ligand

Chemistry – A European Journal, EarlyView.
Bulky N‐heterocyclic carbene (NHC) ligand DiMeIHeptCl stabilizes rare two‐coordinate 13‐electron PdI species. These monomeric complexes are directly observed crystallographically and by electron paramagnetic resonance (EPR) spectroscopy, and display unusual structures and radical‐type reactivity, forming Pd0(NHC) via Pd─X bond homolysis or ...

Distributed Estimation of the Curve Number (CN) in Continental Ecuador Using Machine Learning, Official Geo-Pedological Data, and Field-Based Hydrological Validation

Hydrology
The Curve Number (CN) remains one of the most widely applied parameters for estimating direct surface runoff. However, its conventional application based on watershed-aggregated tabulated values conceals hydrological variability in regions with ...

Review of CFD modelling techniques for single‐phase and multiphase flow in static mixers

The Canadian Journal of Chemical Engineering, EarlyView.
This review synthesizes computational fluid dynamics (CFD) approaches for static mixers, linking hydrodynamics to pressure drop, particle/droplet distributions, mixing metrics, and heat‐transfer performance to guide modelling choices and design decisions. Abstract Static mixers enable compact and low‐energy intensification.

Geospatial estimation of soil moisture in rain-fed paddy fields using SCS-CN-based model

Paddy fields are characterized by standing water and saturation condition during the entire crop growth period. However, in sub-humid and semi-arid areas, scarce rainfall and intermittent dry spells often cause soil moisture depletion resulting in ...
