Precipitation Resource Potential in Mountainous Areas in Hebei Province Analysis
The climatic conditions of Hebei Province cause this area shortage of water resources, man-made factors lead it more serious. In March 2007 in Hebei , 37 mountain counties got samples of soil and corn, conducted indoor tests, through analyzing Hebei rainfall and soil moisture and corn yield in mountains, using potential resource calculated model to precipitation, they analyzed and evaluated pre...
متن کاملMapping Snow Cover in Alpine Areas with Envisat/sar Images
RESUME It has been established that optical and near-infrared sensors can monitor the seasonal variations of snow cover in alpine areas in cloud free conditions. However, only microwave sensors are able to acquire data independently of day light and in adverse weather conditions. The effects of dry snow on currently available C-band SAR data are rather small and difficult to detect. On the cont...
متن کاملDownscaling Snow Cover Fraction Data in Mountainous Regions Based on Simulated Inhomogeneous Snow Ablation
High-resolution snow distributions are essential for studying cold regions. However, the temporal and spatial resolutions of current remote sensing snow maps remain limited. Remotely sensed snow cover fraction (SCF) data only provide quantitative descriptions of snow area proportions and do not provide information on subgrid-scale snow locations. We present a downscaling method based on simulat...
متن کاملشبیه سازی سطح پوشش برف و رواناب ناشی از ذوب آن در حوزه آبخیز هرو - دهنو در استان لرستان
Given the importance of snow, it seems necessary to predict its resultant runoff for optimized usage. In addition, due to snowbound regions cloudiness in winter season, the notice of snow cover area (SCA) using satellite images is difficult. Hence, to help better water resources managing in mountainous areas using supplementary methods for simulating the SCA is necessary. As a case study, Horo-...
