چکیده

Environmental and ecological statistics is poised for dramatic growth both for reasons of societal challenge and information technology. It is becoming clear that environmental and ecological statistics is demanding more and more of non-traditional statistical approaches. This is partly because environmental and ecological studies involve space, time and relationships between many variables, and require innovative and cost-effective monitoring, sampling and assessment. Also, environmental and ecological statistics methodology must satisfy environmental policy needs in addition to disciplinary and interdisciplinary environmental and ecological research imperatives. And all of this is true of research and policy issues involving water and watersheds for disciplinary and cross disciplinary research, such as: (i) a need to develop an enhanced predictive understanding of the processes and mechanisms that govern the dynamics and properties of surface and subsurface water and watershed ecosystems; (ii) a need to identify and research indicator variables, analytical methods, and other tools for determining waters and watersheds at risk and reducing the uncertainties of extrapolating information across broad spatial and temporal scales; and (iii) a need to interpret relationships between populations and communities of organisms and the quality and quantity of water, particularly as these relate to ecosystem processes, land use patterns, and landscape structure.

Modeling of monthly flow duration curve using nonlinear regression method for un-gauged watersheds of Ardabil Province

The flow duration curve (FDC) represents the frequency distribution of water flow over a period of time, which is widely used in hydrology to evaluate different ranges of river water flow applications. Therefore, it is necessary to develop a suitable estimation model and method in un-gauged watersheds. To this end, in the present study, a modeling method based on nonlinear regression, for the p...

Performance comparison of land change modeling techniques for land use projection of arid watersheds

The change of land use/land cover has been known as an imperative force in environmental alteration, especially in arid and semi-arid areas. This research was mainly aimed to assess the validity of two major types of land change modeling techniques via a three dimensional approach in Birjand urban watershed located in an arid climatic region of Iran. Thus, a Markovian approach based on two suit...

واسنجی و تحلیل عدم‌قطعیت یک مدل نیمه‌توزیعی در یک منطقه ‌نیمه‌خشک

Application of conceptual hydrological models is an important issue in watersheds for researchers, especially in arid and semi-arid regions. The hydrological behaviors are complicated in such watersheds and their calibration is more difficult. In this article, the conceptual and semi-distributed SWAT model is used for a semi-arid Nishabour watershed with 9350 km2 area. Streamflow simulation is ...

Identification of critical sediment source areas across the Gharesou watershed, Northeastern Iran, using hydrological modeling

In this study, the process-based watershed model, Soil and Water Assessment Tool (SWAT), was used for simulating hydrology and sediment transport in the Gharesou watershed and for identifying critical areas of soil erosion and water pollution. After model calibration and uncertainty analysis using SUFI-2 (Sequential Uncertainty Fitting, ver. 2) method, the outputs of the calibrated model were u...

Study of relationship between spatial variation of sediment yield and disrtribution of landform components (Case study: Qarasu watershed)

Extended abstract 1- Introduction Erosion and sedimentation in watersheds has caused many problems in healthy and sustainable use of water and soil resources, and is considered as one of the major threats to global economic and environmental sustainability. The increase of sediment yield in watersheds has consequences such as dam filling, river diversion, conductivity capacity reduction of wa...
