Watershed hydrological model design method based on storage capacity curve and TOPMODEL

The invention provides a watershed hydrological model design method based on a storage capacity curve and a TOPMODEL, which comprises the following steps: calculating surface runoff yield; calculating subsurface runoff yield; calculating evapotranspiration; applying a water balance equation; establishing a convergence mechanism; generating isochrones; dynamically and visually expressing soil moisture; and coupling with a Noah land surface model (Noah LSM). The method has a high simulation deterministic coefficient, is advantageous over a semi-distributed model TOPMODEL, a Xinanjiang model and distributed hydrological models such as an engineering and science summer institute (ESSI) model, a hydrologic engineering center hydrologic modeling system (HEC-HMS) model and a soil and water assessment tool (SWAT) model in the simulation of a daily runoff process and the simulation of a flood process, and overcomes the drawback that the conventional watershed hydrological model is usually inapplicable to hydrological process accurate simulation under large-scale, arid and semiarid conditions. The model of the invention can be successfully coupled with Noah LSM and improves the rainfall, soil moisture and runoff broadcasting capacity of a service weather research forecast mode, namely global/regional assimiliation prediction system (GRAPES)-mesoscale(MESO).

Optimized high-speed magnetic resonance imaging method and system using hyperpolarized noble gases

A system and method for using hyperpolarized noble gases together with an appropriately designed and optimized magnetic resonance imaging pulse sequence to rapidly acquire static or dynamic magnetic resonance images. The strong magnetic resonance signal from hyperpolarized gases, combined with the present magnetic resonance imaging technique, presents the opportunity for the imaging of gases with both high spatial and high temporal resolution. One potential application for such a method is the direct, dynamic visualization of gas flow, which would be extremely useful for characterizing a variety of fluid systems. In the medical field, one such system of substantial importance is the lung. The system and method provides for visualizing regional ventilatory patterns throughout the respiratory cycle with high temporal and high spatial resolution. The low sensitivity to susceptibility artifacts permits good image quality to be obtained in various orientations. Depending on the application, temporal resolution can be traded for anatomical coverage. Such application of dynamic imaging of the lung using hyperpolarized gases will provide unique information on the physiology and pathophysiology of the lung, and has the potential for many clinically-relevant applications.
