Simulation models are powerful tools in support of watershed analysis and assessment of management scenarios at the watershed scale. This paper integrates geographic information systems (GIS) and agricultural nonpoint source pollution model (AGNPS) to analyze the effect of land use change on nonpoint source pollution in a study watershed. ArcView nonpoint source pollution modeling (AVNPSM), an ...
Watershed management and planning is a complex decision-making process, which not only involves deliberation using one or more watershed models, but also requires collaboration among multiple stakeholder groups with different ideologies, interests, and demographics. Web-based decision support tools have great potentials to enhance the transparency and participation of such decision making proce...
The tenets of watershed management – a focus on the land area linked to the water body, the incorporation of sound scientific information into the decision-making process and stakeholder involvement throughout the process – are well-suited for the management of cyanobacterial harmful algal blooms (C-HABs). The management of C-HABs can be viewed as having two main areas of focus. First, there is...
Quantifying the effects of forest changes on hydrology in large watersheds is important for designing forest or land management and adaptation strategies for watershed ecosystem sustainability. Minjiang River watershed, located in the upper reach of the Yangtze River basin, plays a strategic role in the environmental protection and economic and social well-being for both the watershed and the e...
Nowadays watershed catchments have been introduced as the main point of permanent development in many management discussions. Watershed catchments ecological power assessment and their rankings according to different Ethological criteria is one of the important factors in watershed catchments planning and management. Taxonomy method is one of the most comprehensive planned systems for assessing...
Integrated watershed management is considered as a new principle for development planning and management of water and soil resources emphasizing on socio-economic characteristics of the region to sustainable livelihoods without vulnerability for plants and the residents of an area. This research, in line with the objectives of integrated management, has been carried out for modelling and evalua...
The upsurge of interest in watershed management and planning has increased the need for user friendly, interactive methods that decision makers can use to evaluate the economic and environmental consequences of alternative land use/management practices (LUMPs). Knowledge and information from several disciplines are integrated into a functional computer-based watershed management decision suppor...
Soil erosion, due to intensive agricultural practices, has been and continues to be of significant concern in the Whitewater Watershed, a coldwater tributary of the Mississippi River, in southeastern Minnesota. Conservation efforts, in the form of best management practices (BMPs) have been underway for many years and a number of residents have enrolled in various government programs designed to...
in order to determine hydrological behavior and water management of sepidroud river (north of iran-guilan) the present study has focused on stream flow prediction by using artificial neural network. ten years observed inflow data (2000-2009) of sepidroud river were selected; then these data have been forecasted by using neural network. finally, predicted results are compared to the observed dat...
An approach to developing and using Bayesian networks to model watershed management decisions is presented with a case study application to phosphorous management in the East Canyon watershed in Northern Utah, USA. The Bayesian network analysis includes a graphical model of the key variables in the system and conditional and marginal probability distributions derived from a variety of data and ...
