Abstract
Sedimentation at the Krutynia River inflow to Lake Kujno was closely related to hydrological regime. The highest sedimentation rates, recorded in spring, decreased during summer by two orders of magnitude. Granulometric segregation of settling seston along the inflow zone was related to differentiation of phoshorus content. Smaller particles were richer in P, producing a gradient of increasing P concentrations in the settling material. A substantial loss of P from polyphosphate and various organic fractions was found after settlement of river suspensoids. Mechanisms of P losses are discussed and possibilities of P retention within the inflow zone are considered.
