Abstract > Observations and a numerical model are used to characterize sediment transport in the tidal Hudson River. A sediment budget over 11?years including major discharge events indicates the tidal fresh region traps about 40% of the sediment input from the watershed. Sediment input scales with the river discharge cubed, while seaward transport in the tidal river scales linearly, so the tidal river accumulates sediment during the highest discharge events. Sediment pulses associated with discharge events dissipate moving seaward and lag the advection speed of the river by a factor of 1.5 to 3. Idealized model simulations with a range of discharge and settling velocity were used to evaluate the trapping efficiency, transport rate, and mean age of sediment input from the watershed. The seaward transport of suspended sediment scales linearly with discharge but lags the river velocity by a factor that is linear with settling velocity. The lag factor is 30–40 times the settling velocity (mm?s ?1 ), so transport speeds vary by orders of magnitude from clay (0.01?mm?s ?1 ) to coarse silt (1?mm?s ?1 ). Deposition along the tidal river depends strongly on settling velocity, and a simple advection‐reaction equation represents the loss due to settling on depositional shoals. The long‐term discharge record is used to represent statistically the distribution of transport times, and time scales for settling velocities of 0.1?mm?s ?1 and 1?mm?s ?1 range from several months to several years for transport through the tidal river and several years to several decades through the estuary. </abstract> </span> <span class="z_kbtn z_kbtnclass hoverxs" style="display: none;">展开▼</span> </div> <div class="translation abstracttxt"> <span class="zhankaihshouqi fivelineshidden" id="abstract"> <span>机译：</span><Abstract Type =“main”XML：Lang =“en”> <标题类型=“main”>抽象</ title> >观察和数字模型用于在潮汐哈德逊河河流中的沉积物运输。超过11？多年的沉积物预算包括主要放电事件，表明潮汐新鲜区域捕集到流域的大约40％的沉积物。沉积物输入鳞片与河流放电立方体，而潮汐河的海上运输线性地缩放，因此潮汐河在最高放电事件期间积聚沉积物。与放电事件相关的沉积物脉冲散发出海面并滞后河流的平流速度为1.5至3.使用范围的放电和稳定速度的理想模型模拟用于评估诱捕效率，运输率和平均年龄流域输入的沉积物。悬浮沉积物的海上运输线性地排出，但河流速度滞后于具有稳定速度的线性。滞后因子是沉降速度的30-40倍（mmΔs 1 </ sup>），因此运输速度从粘土（0.01ΩΩ01ΩΩ0.01ΩΩ0.01ΩΩ0.01ΩΩ0.01？ >）到粗淤泥（1？mm？s 1/1 / sup>）。沿潮汐河沉积在稳定速度上强烈取决于沉降速度，并且简单的平坦反应方程代表沉积浅层沉降引起的损失。长期排放记录用于统计上的传输时间分布，并且稳定速度为0.1ΩΩ·s Δ1和1Ω·s ？1 < / sup>从几个月到几年到几年来，通过潮汐河流，几年到几十年来通过河口。 </ p> </ abstract> </span> <span class="z_kbtn z_kbtnclass hoverxs" style="display: none;">展开▼</span> </div> </div> <div class="record"> <h2 class="all_title" id="enpatent33" >著录项</h2> <ul> <li> <span class="lefttit">来源</span> <div style="width: 86%;vertical-align: text-top;display: inline-block;"> <a href='/journal-foreign-34664/'>《Journal of geophysical research.
