The influences of climate change on water resources availability in Jinjiang Basin, China, were assessed using the Block-wise use of the TOPmodel with the Muskingum-Cunge routing method (BTOPMC) distributed hydrological model. The ensemble average of downscaled output from sixteen GCMs (General Circulation Models) for A1B emission scenario (medium CO2 emission) in the 2050s was adopted to build...
This paper focuses on the integration of basin sediment transport with a physically-based hydrological model that links the water budget model WaSiM (Water Simulation Model) to the erosion model AGNPS__5. The results of the water budget simulation are then incorporated into the AGNPS_5 model to calculate sediment transport. The surface runoff calculated in WaSiM replaces the SCS curve number ru...
An Ensemble Kalman filter (EnKF) is used to assimilate airborne measurements of 1.4 GHz surface brightness temperature ðTBÞ acquired during the 1997 Southern Great Plains Hydrology Experiment (SGP97) into the TOPMODEL-based Land–Atmosphere Transfer Scheme (TOPLATS). In this way, the potential of using EnKF-assimilated remote measurements of TB to compensate land surface model predictions for er...
مدلهای رقومی ارتفاعی (DEMs) به علت دارا بودن ساختار بسیار ساده و کارایی بالا جهت انجام محاسبات در مدلهای ریاضی بارش و رواناب، مورد توجه بسیاری قرار دارند. در حال حاضر روشهای مختلفی جهت درونیابی دادههای توپوگرافی و ساخت مدل ارتفاعی رقومی وجود دارد. در این تحقیق برای ساخت DEM از 6 روش مرسوم نظیر IDW، کریجینگ و کوکریجینگ در محیط ARCGIS استفاده به عمل آمده است. پس از تهیه DEMهای مورد نظر، از ...
Ten years after the Predictions in Ungauged Basins (PUB) initiative was put forward, known as post-PUB era (2013 onwards), reducing uncertainty hydrological prediction ungauged basins still receives considerable attention. This integration or optimization of traditional regionalization approaches is an effective way to improve river discharge simulation basins. In Jialing River, southwest China...
Flood management is an important topic worldwide. Precipitation the most crucial factor in reducing flood-related risks and damages. However, its adequate quality sufficient quantity are not met many parts of world. Currently, near real-time satellite precipitation products (NRT SPPs) have great potential to supplement gauge rainfall. NRT SPPs several biases that require corrections before appl...
