The tutorial is prepared to use the J2000 hydrological model for hydrological system analysis of a river catchment. A test catchment and dataset of the Dudh Kosi river basin has been provided with the detailed description to prepare those dataset. The statement of problems, motivation, objectives and methodological apporach for the study area and the rational of using the J2000 model in the study area are also presented. The users can use the data to get familiar with the model application. At the same time, users can prepare their own dataset to understand the hydrological system dynamics of any river basin.

The example dataset presented here is from the Dudh Kosi river basin in the Himalayan region. The model application was used as a part of the PhD research study which can be accessed from the following link: PhD Thesis

The information provided here is largely based on this study.

Who can use the tutorial

The tutorial is prepared in such a way that the J2000 hydrological model can be used independently without any techtical support from the model developers. Therefore, it can be used by students, model developers and researchers for the hydrological system analysis of a catchment.

The requirement of the data to run the J2000 hydrological model is discussed in detail which is a pre-requisite and important step. Two types of data are required i) model parameter files and ii) meteorological input data. The first one is prepared and quantified inside the GIS environment and known as model parameter files (Section ). The parameter files and their values are static in the modelling application. The detailed descriptions to derive the parameter files are provided below:
