DYPTOP: a cost-efficient TOPMODEL implementation to simulate sub-grid spatio-temporal dynamics of global wetlands and peatlands
global wetlands peatlands
2014/12/19
Simulating the spatio-temporal dynamics of inundation is key to understanding the role of wetlands under past and future climate change. Earlier modelling studies have mostly relied on fixed prescribe...
利用GLUE方法不同算法分析TOPMODEL模型不确定性

以丹江的西峡流域为研究对象，采用ＧＬＵＥ方法探讨ＴＯＰＭＯＤＥＬ模型不确定性。分析不同似然函数算法、调节
参数、模型参数和结果预测区间的不确定性，结果表明不同算法的似然函数值既有差异又有相似性，值变化会引起不同
似然函数分布的变化，也影响模型参数与似然值的关系。分析不同阈值的９０％置信区间的实测值覆盖率、预测区间宽度
及预测区间对称性等特征，结果说明阈值越小，预测区间的可靠性越高，但不确定性...

By using topographic indices as derived from a Digital Terrain Models (DTM), it is possible to represent the heterogeneity within a landscape. This heterogeneity can reflect both long term evolutiona...
Simulating typhoon-induced storm hydrographs in subtropical mountainous watershed：an integrated 3-layer TOPMODEL
typhoon-induced subtropical mountainous watershed storm hydrographs
2009/4/27
A three-layer TOPMODEL is constructed by integrating diffusion wave approach into surface flow, soil moisture deficit into inter flow and exponential recession curve function into base flow. A subtrop...
Digital terrain analysis of the Haute-Mentue catchment an scale effect for hydrological modelling with TOPMODEL
digital elevation model topographic index
2009/3/24
It is widely recognised that topography plays an important role in the generation of runoff. The scale of a digital elevation model has been found to have some impacts on the results of hydrological m...
用TOPMODEL模拟流域径流的应用研究
2007/12/14
摘要介绍了TOPMODEL模型的结构及其产汇流计算原理，分析了地形指数在TOPMODEL模型中的意义，并介绍了地形指数的计算方法。将TOPMODEL模型应用在修河水系的万家埠流域的径流模拟中，DEM分辨率取为500 m×500 m，时间步长为6小时，并与新安江模型作了比较分析。
