A watershed management program is usually based on the results of watershed modeling. Accurate modeling results are decided by the appropriate parameters and input data. Precipitation is the most important input for watershed modeling. Precipitation characteristics usually exhibit significant spatial variation, even within small watersheds. Therefore, properly describing the spatial variation o...

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...

Extended abstract 1- Introduction Soil erosion and sediment production include fundamental limitations in the use of soil and water resources. The sediment yields watersheds in addition to the loss of soil fertility, causing water quality reduction. Therefore, evaluation processes that govern their behavior to better understand and assess the systems of watershed management practices are imp...

1. INTRODUCTION As watershed models become increasingly sophisticated and useful, there is a need to extend their applicability to locations where they cannot be calibrated or validated. It is only natural that as watershed models, computer technology and hydrometeorologic data sources continue to evolve, there will be an ever increasing need to apply watershed models where streamflow data is u...

Ecological flow (E-flow) determination is an essential component of stream management and the preservation aquatic ecosystems within a watershed. E-flow should be determined while considering overall status watershed, including hydrological cycle, hydraulic facility operation, ecology. The purpose this study to determine by watershed through coupled modeling with SWAT PHABSIM. was calibrated en...

[1] Environmental models have become increasingly complex with greater attention being given to the spatially distributed representation of processes. Distributed models have large numbers of parameters to be specified, which is typically done either by recourse to a priori methods based on observable physical watershed characteristics, by calibration to watershed input-state-output data, or by...

The land-use change, cutting forest trees and the grasslands conversion to agricultural lands destroyed natural ecosystems and also current or future production capacity reduce and these are harmful effects on the soil physicochemical characteristics. This study taken with aim, checking the role of forest-land change on some soil physical-chemical characteristics and then identify some effectiv...
