Water conservation is the use and management of water for the good of all users.Soil conservation is defined as the control of soil erosion in order to maintain agricultural productivity. 0000007459 00000 n 0000009167 00000 n Protecting the Soil from Water and Wind Erosion Cover crops can provide surface protection for the soil (Pimentel and Kounang, 1998), especially during peri-ods when the soil is not being used for a cash crop. There are four basic principles of erosion control and properly implementing all of them is the only way to ensure effectiveness. The best choice of plants to prevent soil erosion are herbs, wild flowers and small trees. 0000009998 00000 n 0000002589 00000 n Observe basic principles such as: 1) Preserve existing vegetation as much as possible; 2) Mulch or seed bare soil immediately for the best and cheapest erosion protection; 3) Use silt fences, brush barriers, or other approaches to pond and filter sediment from runoff; 4) Install silt check dams made of rock, brush, or other products to prevent trailer << /Size 263 /Info 167 0 R /Root 169 0 R /Prev 113058 /ID[<14220e47df108c0e1cec02dfaa2cd264><14220e47df108c0e1cec02dfaa2cd264>] >> startxref 0 %%EOF 169 0 obj << /Type /Catalog /Pages 155 0 R /JT 166 0 R /PageLabels 153 0 R /PageMode /UseOutlines /ViewerPreferences << /HideToolbar false /HideMenubar false /HideWindowUI false /FitWindow false /CenterWindow false >> /OpenAction 170 0 R /Outlines 172 0 R >> endobj 170 0 obj << /S /GoTo /D [ 171 0 R /FitH 792 ] >> endobj 261 0 obj << /S 404 /O 615 /L 631 /Filter /FlateDecode /Length 262 0 R >> stream 0000006795 00000 n /A 198 0 R /Next 195 0 R /Prev 199 0 R /Parent 172 0 R >> endobj 198 0 obj << /S /GoTo /D [ 113 0 R /XYZ 0 456 null ] >> endobj 199 0 obj << /Title (Objective 6:) /A 200 0 R /Next 197 0 R /Prev 201 0 R /Parent 172 0 R >> endobj 200 0 obj << /S /GoTo /D [ 101 0 R /XYZ 0 341 null ] >> endobj 201 0 obj << /Title (Objective 5:) /A 202 0 R /Next 199 0 R /Prev 203 0 R /Parent 172 0 R >> endobj 202 0 obj << /S /GoTo /D [ 83 0 R /XYZ 0 236 null ] >> endobj 203 0 obj << /Title (Objective 4:) /A 204 0 R /Next 201 0 R /Prev 205 0 R /Parent 172 0 R >> endobj 204 0 obj << /S /GoTo /D [ 83 0 R /XYZ 0 523 null ] >> endobj 205 0 obj << /Title (Objective 3:) /A 206 0 R /Next 203 0 R /Prev 207 0 R /Parent 172 0 R >> endobj 206 0 obj << /S /GoTo /D [ 67 0 R /XYZ 0 218 null ] >> endobj 207 0 obj << /Title (Objective 2:) /A 208 0 R /Next 205 0 R /Prev 209 0 R /Parent 172 0 R >> endobj 208 0 obj << /S /GoTo /D [ 67 0 R /XYZ 0 734 null ] >> endobj 209 0 obj << /Title (Objective 1:) /A 210 0 R /Next 207 0 R /Prev 211 0 R /Parent 172 0 R >> endobj 210 0 obj << /S /GoTo /D [ 45 0 R /XYZ 0 472 null ] >> endobj 211 0 obj << /Title (Interest Approach.)

When land is cleared of protective covering, it is much more susceptible to erosion. The bulletin outlines factors that influence soil erosion from water, including rainfall and runoff intensity, soil erodibility, cropping and vegetation, slope length and gradient, and tillage practices. Soil erosion includes the processes of detachment of soil particles from the soil mass and subsequent transport and deposition of those soil/sediment particles. 3. Conversion of 137Cs data to soil loss values 31 7. Eroded topsoil particles contain a higher percentage of clay minerals, organic matter and nutrients than the remaining (sub-) soil itself. 0000003233 00000 n PRINCIPLES OF EROSION CONTROL ON CONSTRUCTION SITES 3.1 Planning Phase Controls 12 A practical way of combating erosion is to plan control measures before work starts on a project. $�"Lp��0��]4�V��'��]�N^�c�E #6H�,��^>�3��3��3��W�_d�32P�j��)��(��k�Ԗ�~��T՞��:�S�p�{�(��]��e�{�m�|��y�6�cL�.- _�2�j��_��U0��&c� �B4��i��U�&��1��d�Fn%&��Q�ES�v�M��vN]�S��4�VK(�P�yT*�P��N��꡾�1��ԝ�Zt�&�>"�.Ц�� @�� 0000006041 00000 n 0000003211 00000 n GENERAL DESIGN PRINCIPLES For an erosion and sedimentation control Figure 2.2. 0000003694 00000 n 2 7KH VRLO HURVLRQ SURFHVV EHJLQV E\ ZDWHU IDOOLQJ DV UDLQGURSV DQG ÀRZLQJ RQ the soil surface.
