Abstract
Social, economic and political development of a region is dependent on the health and quantity of the natural resources. Integrated approaches in the management of natural resources would ensure sustainability, which demands inventorying, mapping and monitoring of resources considering all components of an ecosystem. The monitoring of hydrological and catchment landscape of river resources have a vital role in the conservation and management of aquatic resources. This paper presents a case study Venkatapura river basin in Uttara Kannada district of Karnataka State, India based on stream hydrology and land-use analyses. The results revealed variations in dissolved oxygen and free carbon dioxide according to the flow nature of the water and increased amount of phosphates and coliforrn contamination in streams closer to anthropogenic activities.
