Recently, a manuscript was published with the objective to complete a multivariable and multisite calibration and validation for the Soil and Water Assessment Tool (SWAT) model on the Motueka River basin by Cao et al. (2006). Physically based distributed parameter models, such as SWAT, have become a preferred tool to predict watershed response not only at the watershed outlet, but also at inter...

A common theme in recent landscape studies is the comparison of riparian and watershed land use as predictors of stream health. The objective of this study was to compare the performance of reach-scale habitat and remotely assessed watershed-scale habitat as predictors of stream health over varying spatial extents. Stream health was measured with scores on a fish index of biotic integrity (IBI)...

Models are necessary tools for watershed management. However, applying watershed models is time consuming and requires technical knowledge, including model selection and validation. The objective of this study is to assess two commonly used watershed models and their parameter sensitivity to reduce model loadings and to gain a better understanding of the model performances. The Hydrological Sim...

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...

Storage routing models are becoming more widely accepted for flood hydrograph synthesis. The network models represent a considerable advance in this direction even though these models are based on many assumptions and empirical relationships. Watershed Bounded Network Model (WBNM) is one such model. This model maintains a good relationship between the hydrological and geomorphological propertie...

Watershed scientists use different computer based modelling tools to model the physical processes around watersheds. In this work we have created a software environment for assisting watershed scientists in their research. This software environment will provide a platform to share different data with fellow scientists and run different models in the cloud through web services. It will also prov...

Watershed transform is considered to be an important technique in image segmentation. It is the method for image segmentation in the section of mathematical morphology. Work of watershed segmentation proceeds using the neighboring pixels. We present a critical review of several definitions of the watershed transform and the associated sequential algorithms, immersion models and therefore parall...
