Physical principles of climate mathematical modelling
Hydrological processes and water resources in the face of global climate change
Atmospheric circulation ; Climate ; Climatic variability ; Forecast ; Global change ; Human impact ; Mathematical model ; Model
In this paper the nature, state and variability of the climate system are described briefly. Of particular importance in open systems such as components of the climatic system is feedback. Mathematical models provide a new way to not only understand

Morphogenetic classification of river valleys developing in formerly glaciated areas for the needs of mathematical and physical modelling in hydrotechnical projects
Applied hydrology ; Catchment area;Watershed ; Classification ; Fluvial erosion ; Fluvial processes ; Human impact ; Hydrological regime ; Meander ; Model ; Poland ; River bed
This paper deals with proposals of natural models of river valley evolution useful for physical and mathematical modelling in hydrotechnical projects. Such models are known from investigations of numerous valley reaches of the Wisla (Vistula) River

The purpose of this paper is to develop a simple mathematical model of ground flow so as to permit computing the long term steady state flow in rivers as the runoff component of the hydrological cycle.

Hydrology : the changing paradigm

Hydrology : the changing paradigm
Applied hydrology ; Concept ; Drought ; Global change ; Human impact ; Hydrology ; Model ; Research ; Water cycle ; Water management ; Water resources
Hydrology is an established twentieth-century environmental science, whose content is necessarily interdisciplinary (biology, physics, chemistry, geomorphology and, increasingly, the social environmental sciences such as planning, economics
and political conflict resolution). The 1980s and early 1990s saw debates concerning the scientific credentials of hydrology. While some argued that the nature and pace of human modification of the water cycle, together with the enormous expansion
in the technologies of data capture and manipulation, were enough to warrant a change in philosophy within the subject, others emphasized caution and the need to retrench around core basic science, and to reduce reliance on mathematical modelling.

Modelling alluvial fan morphology

A mathematical model which estimates the scale-independent sediment surface profile of alluvial fans has been developed. This model utilizes a diffusive sediment transport model and an unsteady, radial flow, conservation relationship. The model

Mathematical modelling in the case of the main Czech rivers is based on simulation of water movement in the river bed and on consequent modelling of diffusion of pollutants. It makes possible to calculate a continuous longthwise-profile of water

Steady-state flows occur in a variety of geophysical processes. Their mathematical treatment is usually based on either the dynamic-wave equations or their approximations: kinematic wave (KW) and diffusion wave (DW). Furthermore, when doing
hydrologic modeling it is not evident if the KW and DW approximations are valid for the entire length of the channel or a portion thereof. The objective of this study is to derive, under simplified conditions, errors for the kinematic-wave (KW
