2     Elevated levels of suspended matter                                                           Sediments entering Basin water resources, which is contributed to by:
                                                                                                       (a) the following land management practices:
                                                                                                            (i) inappropriate frequency, timing and location of cultivation;
                                                                                                            Example: Cultivation taking place at times of the year when the risk of erosion is high (e.g. during the high rainfall season), excessive frequency of cultivation, and cultivation of steep slopes.
                                                                                                            (ii) overgrazing of catchments and grazing of riverbanks and floodplains;
                                                                                                            Example:  The riparian zone along watercourses kept in permanent vegetation can effectively mitigate the movement of sediment within farmlands and from farmlands.
                                                                                                            (iii) poor soil conservation practices;
                                                                                                            Example: Practices that fail to use management strategies that prevent soil erosion, acidification, salinisation or other chemical soil contamination, or fail to adopt proven soil conservation technologies such as the construction of contour banks.
                                                                                                            (iv) practices that over the long‑term cause decline of stream morphology, leading to near stream processes of gully erosion, side wall cut and head migration; and
                                                                                                       (b) the following water management practices:
                                                                                                            (i) rapid drawdown of water within a surface water resource;
                                                                                                            Example: Rapid drawdown of water in a dam.
                                                                                                            (ii) the volume or manner of release of water, resulting in back or bed erosion; and
                                                                                                       (c) wave wash (for example, that caused by speedboats).
