the management of sedimentation problems in rivers and reservoirs depend greatly on the sediment yield from the catchment land surface. in this research the effects of biological measures and ranges enclose on suspended load in two sub-catchments of kakhk experimentalwatershed in gonabad has been studied. this catchment contains both control and experimental sub-catchments. these sub-catchments...
The rivers sediment load is determined using hydrologic methods. In the statistical methods, by measuring the rivers discharge and suspended sediment load in a long-term period, the relationships between the suspended sediment load and discharge is obtained. The aim of this study is to compare different estimation methods of suspended load and select the most appropriate relationship for the pr...
in this paper a performance analysis is presented for a cable-suspended parallel manipulator. experimental results from some first tests are presented and discussed to validate the theoretical calculation of load carrying capacity. the load-carrying capacity during a given trajectory is obtained. this computational technique is tested on a typical planar cable suspended manipulator. the experim...
Extended abstract 1- Introduction The phenomena of erosion, sediment transport, and sedimentations have tremendously destructive effects on the environment and hydraulics structures. In general, the sediment transportation depends on river discharges, but the proposed equations inherited serious errors. The estimation of suspended sediment load (SSL) is one of the most important factors in r...
This study is aimed at estimating suspended sediment load in watersheds using hydro-climatic factors with the intent to determine spatial and temporal variations of sediment yield in Qarah Su drainage basin, Ardebil Province. For this study, data from seven rain gauge and hydrometric stations during a 22-year period were used. The research was based on statistical regression analysis between va...
Elastically-suspended loads can reduce the energetic cost of legged robot locomotion over flat ground. In this paper, we studied the effect of elastically-suspended loads on the mobility of legged robot locomotion over rough terrain. The power input and speed of a simple hexapod robot running over rough terrain with an elastically-suspended load and a rigidly-attached load was compared. On aver...
abstract lateral intake is a hydraulic structure which is used for diversion of some portion of water from a river for the purpose of irrigation, storage and industrial. most of lateral intakes from canal are installed at canal with inclined banks which has not received the attention of the researchers in the past. since the flow discharge and sediment which enters the intake canal depends on t...
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...
