Accelerated soil erosion is the most important degradation factor of soil and water resources. Typically, soil erosion involves the detachment and transport of soil particles by rainfall, shallow surface flow or the interaction of these two factors. Therefore, understanding the motion threshold of sediment particles and temporal variation of sediment concentration in flow-induced can provide a detailed cognition of the processes inducing soil erosion and sediment transport and their eventual interactions. It is also important for increasing the accuracy of soil erosion models. In this study, the particle motion threshold and temporal variation of sediment were studied for a sandy sample at three slopes; 3.1, 5.9, 8.9% and-dunder three flow
Rainfall-induced erosion involves the detachment of soil particles by raindrop impact and their transport by the combined action of the shallow surface runoff and raindrop impact. Although temporal variation in rainfall intensity (pattern) during natural rainstorms is a common phenomenon, the available information is inadequate to understand its effects on runoff and rainfall-induced erosion processes. To address this issue, four simulated rainfall patterns (constant, increasing, decreasing, and increasing - decreasing) with the same total kinetic energy were designed. Two soil types (sandy and sandy loam) were subjected to simulated rainfall using 15 cm ? 30 cm long detachment trays under infiltration conditions. For each simulation, r
Soil erosion, as a complicated natural phenomenon, is a global challenge threatening soil and water resources. Therefore, accurate understanding of soil erosion and sediment transport processes and their interactions is necessary for prediction of soil erosion. To distinguish between the dominant processes involved in soil loss, soil erosion has been classified into rill and interrill erosion. Rainfall-induced detachment and transport of sediment have a fundamental contribution to interrill and sheet erosion. Instead of the observation of natural rain showers, simulation of rainfall is widely used for better understanding of processes involved in soil erosion and their interactions. Rainfall intensity is variable during a natural rain showe
In this research, MIKE SHE distributed hydrologic model and MIKE NAM lumped hydrologic model has been used for simulation of mean daily flow discharge in Gharasoo river basin in Ardebil province (Iran). Generally in the distributed models, the whole watershed is divided to small elements and the amount of each effective parameter on watershed for each element is considered separately. While in lumped models, watershed is considered as an integrative unit and effective parameters on watershed are considered with their intermediate quantity. Progressed and comprehensive hydrological models for more accurate calculation of flow discharge in watershed have been highly applied in recent years and progresses performed in the development of distri
The term ‘Tracerhydrology’ is used as a short expression for the use of tracers in hydrology. It is understood as an advanced method that allows for an integrative investigation of the hydrologic system (Leibundgut et al. 2009). Environmental and artificial tracer can be used for investigating the movement of water in the hydrological cycle. Artificial tracers are described as those elements deliberately injected into the hydrologic system (Luhua et al. 2010). By studying the motion of the injected particles, one may measure some physical processes of hydrologic system such as the escape of water from a reservoir (Evans 1983). There are more than 1,000 isotopes known for about 92 chemical elements. Most of these isotopes ar
This paper evaluates the efficiency of using surface water simulation results to improve the accuracy of groundwater simulation due to improving the accuracy of its input boundary conditions. The three most important data sets of boundary conditions in groundwater flow simulation are groundwater recharge, evapotranspiration rates and their regional distributions that little information is usually available about them. Moreover, the incorrect definition of these values can lead to uncertain groundwater modeling that is not applicable for groundwater resources management. In the most of previous studies done in Iran, percentage of the average regional precipitation and the local pan evaporation data (available from local weather stations) are
In this research, two scenarios of drought forecast were studied. In the first scenario, the time series of monthly streamflow were converted into the Standardized Hydrological Drought Index (SHDI), a similar index to the well‐known Standardized Precipitation Index (SPI). Multi‐layer feed‐forward artificial neural network (FFANN) was trained with the SHDI time series to forecast the hydrological drought of Karoon River in southwestern Iran. In the second scenario, the time series of monthly streamflow discharge was forecasted directly and then converted to the SHDI. Principal component analysis (PCA) and forward selection (FS) techniques were applied to remove dependency of inputs and reduce the number of input variables, respectivel
The moment-curvature envelope describes the changes in the force capacity with deformation during a nonlinear analysis. Therefore, the moment-curvature envelopes for columns, beams and shear walls form an essential part of the analysis. The program IDARC now provides an option for users to input their own cross-section properties directly, and the moment-curvature is computed internally. Since IDARC is most practical and well-known software in damage analysis and the value of Park damage index depends strongly on the ultimate curvature, truth of IDARC's results in section analysis is so highlighted. In IDARC, the moment-curvature analysis is carried out on the cross-section by dividing the concrete area into a number of strips or fibers. Th
The purpose of this study is to survey the impact of climate change on the runoff of Gharehsoo River in northwest of Iran. In this research the outputs of monthly precipitation and temperature data of PRECIS model, which is a regional climate model with 50? 50 km resolution on the basis of B2 scenario, have been utilized for base (1961-1990) and future (2071-2100) periods. The output results of PRECIS model show that the average temperature of watershed increased up to 2 C-5 C. In addition, future precipitation is more than the base precipitation on January, February, March, September and December. The observed data of 1996-2002 used for calibration of HSPF model and the data of 2003-2004 were used for HSPF validation. The present monthly p
Using of hydrological models for realization hydrological processes in watersheds has been highly developed in recent years and a lot of research has been reported on this topic. The HSPF Model, Hydrologic Simulation Program Fortran, is a US EPA program for simulation of watershed hydrology and water quality for both conventional and toxic organic pollutants. The HSPF model uses information such as the time history of rainfall, temperature and solar radiation; land surface characteristics such as land use patterns; and land management practices to simulate the processes that occur in a watershed. The result of the simulation by this model is a time history of the quantity and quality of runoff from an urban or agricultural watershed. Flow r
Introduction:Precipitation and temperature patterns have especial role in the accuracy of hydrologic models. future patterns of rainfall and temperature can lead to better hydrological predictions. Hence, according to their importance, we try to derive the future rain and temperature patterns of the Gharehsoo River’s watershed. This watershed is in the northwest of Iran in the Ardebil province and it has high amount of agriculture productions. Interpolation schemes are utilized in this study to determine rain and temperature patterns. The utilized software package is ArcGIS software.
Water distribution in soil is important for the design, operation, and management of irrigation system for arid and semi-arid regions. The present paper has attempted to estimate the wetted radius and vertical depth from Buried porous clay capsule irrigation using fuzzy model. A fuzzy reasoning algorithm is used to define the relationship between the saturated hydraulic conductivity, discharge, porosity, water volume applied and hydrostatic pressure head and the surface wetted radius and vertical depth. Singleton fuzzyfier, minimum Mamdani inference engine and centriod defuzzyfier are selected to determine soil water distribution using observed data of calcareous soil with clay loam texture in TMU. To obtain porous clay capsules with differ
This paper presents a simple method for including elevation into spatial interpolation of annual rainfall in a 4000 km2 region located in Ardebil province in the North-West of Iran. We considered an elevation factor in calculating distance in three-dimensional Inverse Distance Weighting (IDW) method. The effects of using various amounts for this factor on obtained distributed annual rainfall map have been evaluated.
