LUPWY: land use planner for water yield for environmental change analysis
- 70 Downloads
Sustainable land use of watershed is an important aspect for the development and conservation of nature. Unconcerned use of the resources may lead to irreversible consequences and overall misbalance. The main aim of the research was to create a software, which could be useful for estimation of the catchment’s nature conditions and assessment of changes on the basis of which the prediction of possible consequences can be made. In the given work, the influencing factors have been considered: precipitation and temperature analysis and land cover change over the last 30 years. With the help of the developed model based on the provided data, the representation of changes in climate, land cover and water dynamics were calculated. As a result, the software establishes the characteristics of the catchment area and makes it possible to see the changing pattern of the selected factors. The primary and secondary outcomes of the model provide precise calculation of surface runoffs, interception losses, and transpirations. In order to assess the effectiveness of the model, the results of the model and the river discharge were compared with estimation of the possible error rate. Different territories with similar characteristics can implement developed software for daily use on the local level. However, for successful applying in a new area the model has to be localized. Further evolvement is necessary in order to make the model applicable to any different location with specific features which can be different from the original example provided.
