An Overview on High-Resolution Globalscale Hydrological Model
|
Abstract:
In this paper,an overview on High-Resolution Globalscale Hydrological Model(HRGHM) is presented from review of models,summary of general model structure and characteristics,advances in model data set and introduction of problems involved in the model development.HRGHM provides hydrologist an opportunity to look the hydrological properties and variabilities consistently in a global manner.Besides,it also plays a significant role in settling the relevant environment problems,simulation of future climate,water resources management,etc.Despite the plentiful development in global database related with model development,data scarcity is still the biggest problem to HRGHM.Other problems include nonlinear problem,scale problem and uncertainties in the model construction and model practice.
