English Abstract
Soil erosion is worldwide environmental problem.
Assessment of soil erosion is very important for decision maker to make a Plan for soil conservation and watershed management.
This investigation is intended to estimate the annual soil loss in Iraq Sub_watershed by integration between geographic information system and Revised Universal Soil Loss Equation(RUSLE) model.
The study provides two methods for the assessment of soil erosion: The conventional method (soil erosion map), and The interactive tool method.
For the first method, input maps representing the five RUSLE parameters m (R, K, LS, C, and P)were prepared in Arcmap.
The soil erosion map was generated by overlaying the input maps.
The average soil erosion rate was(85) t/ha/year.
The annual soil loss values were between (0 - 38,000) t/ha/year.
The estimated annual soil loss rates were divided into five erosion risk categories.
Approximately 35%of the study areas falls within the tolerable category of (0-2 )t/ha/year, The low (2-4)t/ha/year, moderate (4-20)t/ha/year , high (20-50)t/ha/year and severe ( >50)t/ha/year comprises 6, 20, 14 and 25% of the study area, respectively.
In the second method interactive tool named RUSLE JORDAN was developed by python programming language.
Initial erosion values displayed for each parcel in Iraq Sub_watershed depend on the RUSLE parameters values defaulted from the conventional soil erosion map.
The RUSLE JORDAN tool can be applied on any watershed in Jordan.
The tool consist of many comoboxes related with C, P, and LS factors, while the K and R factors calculated inside the model.
The tool provides the option to choose the appropriate practices, intervention, and real reading of slope and length of slope for reduce erosion value.
Ten scenarios were implemented on randomly selected parcels of Iraq Sub- Watershed.
The results of scenarios shows the impact of the different intervention and management practices on the erosion rate values, thus the tool provides the decision make with the information for the soil selection of soil conservation practices
