Revision as of 13:54, 3 August 2012
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 tutorial should be read in conjunction with other sub-tutorials which has been mentioned in different part of this tutorial.
Description of the test dataset
The test dataset of the Dudh Kosi river basin has been provided along with the tutorial. This dataset has been used for the PhD research and the publications can be download from here. The Department of Hydrology and Meteorology (DHM), Government of Nepal has provided permission to use the data along with the tutorial. The users are expected to use the data to get familar with different aspects of the J2000 modelling system. At the same time, they can also create their own dataset to analyse the hydrological dynamics of a catchment.

Objectives and methods
Preparation of dataset
Model parameter files
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. The parameter files and their values are static in the modelling application. The detailed descriptions to derive the parameter files are provided below:
Soil parameter file
Land cover parameter file
HRUs/Reach parameter file
Hydrological Response Units (HRUs) are the modelling modelling entities for the J2000 hydrological model.
Geological parameter file

Meteorological input data
The J2000 hydrological model requires the input of the hydro-meteorological data as provided in Table below:
