DESCRIPTION:Where does the mud go? Insights into processes that impact the 
 transport and deposition of fine sediment through the fluvial to marine tr
 ansition.\n\nKyle Strom\nAssociate Professor in Civil and Environmental En
 gineering at Virginia Tech\n\n \n\nAbstract \n\nRivers deliver fine muddy 
 sediment eroded from upstream landscapes to coastal regions. Upon arrival\
 , mud can deposit in or move through the rivers\, bays\, estuaries\, marsh
 es\, and deltas of the region. Being able to forecast the movement and eve
 ntual resting spot of this sediment has important implications for society
 . For example\, evaluating the effectiveness of river diversion projects a
 imed at using sediment deposits to build deltaic landscape is dependent on
  being able to accurately model the movement of mud from a high-energy riv
 er to a low-energy embayment. The same is true for developing water qualit
 y models of coastal waterbodies and evaluating how mud deposits shoal wate
 rways and impede vessel navigation. While its importance is known\, modeli
 ng mud movement through coastal waters is complex and difficult. The outco
 me of this complexity is that the predictive power of current methods rema
 ins poor. Part of the complexity is due to the flocculation process whereb
 y mud particles form aggregates\, or flocs\, which grow or shrink in size 
 and density depending on turbulence levels and other water column properti
 es (see figure below). When flocs grow or shrink in size\, the rate at whi
 ch they settle out of the water changes\, creating dynamic settling speeds
  that are difficult to model. Furthermore\, estuarine zones and river mout
 h plumes can be stratified\, with positively buoyant freshwater suspension
 s of mud flowing over clearer saltwater. \n\nThis talk highlights recent w
 ork designed to better understand the vertical flux of muddy cohesive sedi
 ment in the fluvial to marine transition. The talk specifically focuses on
 : (1) the response of flocs sizes to changing shear and concentration cond
 itions\; (2) improvements to simple modeling of floc size in turbulent flo
 ws\; and (3) the effective settling rate of mud in the presence of settlin
 g-driven interfacial instabilities and shear at the contact point between 
 overlying muddy freshwater suspension and underlaying clear saltwater.\n\n
  \n\nBio\n\nKyle Strom is an associate professor in Civil and Environmenta
 l Engineering at Virginia Tech where he teaches and conducts research in t
 he field of environmental hydraulics and sediment transport. Strom receive
 d his BS and MS degrees from Washington State University and a PhD from th
 e University of Iowa. His research focuses on fluid and sediment dynamics 
 of natural systems such as rivers\, estuaries\, fans\, and deltas over a r
 ange of spatial and temporal scales. The underlying motivation for his gro
 up’s work is the understanding of fundamental processes for better forwa
 rd and backward prediction of river and landscape system evolution in time
  under natural and anthropogenic influences. Learn more about Strom.
