CONTENT OF PHYSICAL GEOGRAPHY The object of physical geography is to understand the natural environment at the human rather molecular scale. We are concerned to explain the formation and occurrence of phenomena of the natural environment and the general area aspects of their dispersion, pattern and interrelations. In practice because the field is so large and because certain subjects are more central to other specialised disciplines, we limit our activities to the physical and biological landscapes and to considerations of soil, water and climate. These are the elements of the natural environment that have most direct influence upon mankind. We also analyse the impace of man on the environment and study the application of geographical principles to conservation and planning For the purposes of teaching and research, physical geography is broken down into its component parts of geomorphology, hydrology, climatology, biogeography and pedology. Work in these subjects involves the following: 1. Geomorphology The focus of our interest is on the development and spatial organisation of landforms. While the historical evolution of physical landscape is important, modern emphasis is on quantitative analysis and process-response study. 2. Hydrology Rivers and their valleys, lakes and estuaries are intergral parts of the landscape; thus we examine their organisation, operation and development. Consideration is given to both surface water and groundwater networks. This branch of physical geography is closer to fluvial geomorphology than to hydraulics. 3. Climatology Elements of Climate, such as energy, moisture and wind, are studied collectively as components of the natural environment. The subfields of "applied climatology" and "amospheric resource assessment" deal with relationships between the atmospheric environment and socio-economic aspects of recreation, agriculture, health, comfort, clothing, architechure, commerce, and industry. 4. Biogeography Living organisms, particularly plants, are an important aspect of landscapes; thus our interest embraces distribution, characteristics and interrelations of biota in space, including modifications wrought by man and climatic change. Emphasis is primarily on area, pattern and the geography of biota, rather than on the biota per se. 5. Pedology Soils clothe the landscape and are the by-products of climatic, biologic and geomorphic processes. They therefore form an integral part of our area of enquiry, being worthy of study in their own right as well as for the light they shed on spatial distribution of environmental processes. A knowledge of soils and their potential is also of great importance for land evaluation and agricultural geography. Thw study of all aspects of physical geography is necessary for a full appreciation of human geography. Thus apart from being independent subjects of intrinsic academic merit, these branches of natural science provide an important service to the rest of geography. The applications of physical geography should also be noted, for expert knowledge of geomorphic, climatic, hydrologic, biologic and pedologic processes has clear relevance for environmental management, whether in the fields of land evaluation and development, erosion control, water supply or education. .
