Factors Influencing Rainsplash Erosion and Runoff in an Arid Watershed
نویسندگان
چکیده
Rainfall simulation experiments were. conducted in the Fifteenmile Creek drainage basin of north-central Wyoming to identify nonpoint sources of suspended sediment, A portable drop-forming rainfall simulator was chosen for reasons of l o w cost and low water requirements. drops from a height of 7.5 feet ( 2 . 3 meters) with an intensity of 3 inches ( 7 . 6 cm) per hour. The simulated storms were applied over 73, 2 ' x 2' (.6 x .6 meter) plots for the duration of one hour. These storms, with a kinetic energy of 456 joules, were chcsen as being representative of intense convective storms that occur over the basin in the summer months. Experiments were designed to generate 3 . 2

Kinematic runoff and erosion model efficiency assessment for hydrological simulation of semi-arid watersheds
Hydrologic modeling of semi-arid watersheds is imperative for the development of appropriate water and soil conservation plans. In the current study, the efficiency of Kinematic Runoff and Erosion model-version 2 (K2) model was used to evaluate water discharge and sediment load simulation of Bar watershed, located in the north-eastern part of Iran. The K2 model relies on the kinematic wave appr...
متن کاملRunoff and sediment yield modeling using WEPP in a semi-arid environment (Case study: Orazan Watershed)
Water erosion is a major environmental problem in many parts of the world. Majority of semi-arid countries are concerned because of their specific climate and soils sensitivity, but also because of the recent intensification of human activities and agricultural practices. Accurate estimation of water erosion for various land-use and climate scenarios is so an important key to define sustainable...
متن کاملEffect of natural land covers on runoff and soil loss at the hill slope scale
Erosion plots were selected for characterizing the effects of main natural factors on runoff and soil loss in a semi-arid region. These erosion plots with an area of 40 m2 are located in the Kakhk experimental watershed in Gonabad County of Khorasan-e Razave Province in the north-eastern Iran. Data acquired from 2008 to 2015 include slope, aspect, soil texture and land covers (canopy...
