Estimating Unsaturated Hydraulic Functions for Coarse Sediment from a Field-Scale Infiltration Experiment
Conglomeratic alluvial sediments (sand–gravel–cobbles) are common in fluvial, periglacial, and tectonically active regions but have received little attention with respect to unsaturated flow, specifically moisture–tension–conductivity relationships, due to difficulty in making measurements in the field or laboratory and lack of agricultural value. We used a field-scale infiltration experiment, ...
متن کاملUncertainties in Evaluation of the Sediment Transport Rates in Typical Coarse-Bed Rivers in Iran
Flow and sediment transport processes are different and more complex in coarse-bed rivers than in sand-bed rivers. The main goal of the present study is to evaluate different modes of sediment transport using different hydrometric and hydraulic methods, and to address the major uncertainties. Four river reaches were selected as representatives of coarse-bed rivers in the Northwest of Iran. A se...
متن کاملAssessment of Corrective Methods for Estimating Suspended Sediment Load for Rivers with Debris Sediment Flow Regime in Khorramarood River - Golestan Province
In the present research, changes in sediment regime in two statistical periods of "natural flow" and "modified / debris flow" were evaluated. In order to determine the significant difference between two mentioned periods (1966-1992) and (1993-2015), the significance test was used. In order to determine the most suitable method of Sediment Rating Curve and correction coefficients, the result...
متن کاملThe most Appropriate Statistical Method for Suspended Sediment Estimation of Rivers (Case Study: Roodak Station of the Jajrood Basin)
The sediment load that is transported by rivers can create numerous problems such as sedimentation in the reservoir and storage capacity reduction, developed load in the rivers, destruction of structures along the river and transfer of pollution. Therefore, an accurate estimate of the sediment load in rivers is absolutely essential for river engineering, reservoir design, sediment transportatio...
متن کاملIn situ colloid mobilization in Hanford sediments under unsaturated transient flow conditions: effect of irrigation pattern.
Colloid transport may facilitate off-site transport of radioactive wastes at the Hanford site, Washington State. In this study, column experiments were conducted to examine the effect of irrigation schedule on releases of in situ colloids from two Hanford sediments during saturated and unsaturated transientflow and its dependence on solution ionic strength, irrigation rate, and sediment texture...
