Calibration and evaluation of water infiltration models in different soil textures
Accurate estimation of water infiltration into the soil is important for the design of irrigation systems. Therefore, calibration of different models is necessary to estimate the permeability in different regions. The aim of the present study was to calibrate and evaluate the models of Kastiakov, Kastiakov modified, Philip, SCS, Novell, and Horton in different soil textures. To evaluate the acc...
متن کاملDetermination of Main Agents Affecting Soil Erosion in Rainfed Land of Kermanshah Province Using Rainfall Simulator
In recent decades, low-yielding rainfed farms have become known as the main sources of sediment production and soil erosion in the country. Therefore, more research is needed on the factors affecting erosion and sediment production in these areas. This research was carried out with the aim of studying the effects of slope and rainfall intensity on erosion between rainbow trout in test farms in ...
متن کاملSoil water infiltration observation with microwave radiometers
Experiments were conducted using truck-based microwave radiometers operating at 1.41(L-band) and 2.65-GHz (S-band) horizontal polarization to observe small plots during and following sprinkler irrigation. These experiments were conducted on a sandy loam soil in 1994 and a silt loam in 1995. Sandy loam soils typically have higher infiltration capabilities than clays, and in our studies, we were ...
متن کاملStudying the Relationship between Environmental Factors, Runoff Characteristics and Infiltration Depth Using Rainfall Simulator in Northwestern Rangelands of Iran
Runoff leads to the leaching of soil nutrients, transports the topsoil particles and deposits the sediments in water reservoirs. Recognition of different environmental factors affecting the runoff properties and water infiltration depth has a great importance concerning soil for the integrated management of watershed and the distinguishment of complex hydrological processes. Thus, this research...
متن کاملEstimation of Soil Infiltration in Agricultural and Pasture Lands using Artificial Neural Networks and Multiple Regressions
Common methods to determine the soil infiltration need extensive time and are expensive. However, the existence of non-linear behaviors in soil infiltration makes it difficult to be modeled. With regards to the difficulties of direct measurement of soil infiltration, the use of indirect methods toestimate this parameter has received attention in recent years. Despite the existence of various th...
