Principles of Construction Erosion Control Prevention of urban erosion is best. The best choice of plants to prevent soil erosion are herbs, wild flowers and small trees.

When land is cleared of protective covering, it is much more susceptible to erosion. Conversion of 137Cs data to soil loss values 31 7. 2.1 Types of Erosion Soil erosion is the process by which wind, ice, water and gravity wear away the land’s surface. 0000006385 00000 n In agriculture, soil erosion refers to the wearing away of a field's topsoil by the natural physical forces of water and wind or through forces associated with farming activities such as tillage. Soil erosion is the washing or blowing away (by water or wind) of the top layer of the soil. Wind erosion of sandy coastal soils is often overlooked and can be a major source of sediment leaving a construction site. /A 196 0 R /Next 193 0 R /Prev 197 0 R /Parent 172 0 R >> endobj 196 0 obj << /S /GoTo /D [ 113 0 R /XYZ 0 377 null ] >> endobj 197 0 obj << /Title (Review/Summary.) ���[�| ��/������x��E(.�+p�^�[_���8=�H[Wm��`U����.d�`qv� 6ܜYbe� � �zCVKs3Z-z�c� �2B�� Soil Erosion The Greatest Challenge For Sustainable Soil Management. waterlogging and erosion risks, soil texture, depth and stoniness) reflected in the 0000014318 00000 n An erosion and sediment control program is based on the following principles: • Assess the erosion potential of the site before work starts. 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. Effects of Soil Erosion The most serious problem of Ethiopia’s land resources is soil erosion (Paulos, 2001). 0000006107 00000 n This helps ensure that the soil is held in place against erosion that can often lead to a loss of small particles like clay 0000006279 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. prevents soil erosion and sediment discharges. This handbook explains the causes, processes, and consequences of soil erosion and depletion, and describes the major soil- and water-conservation measures which, when applied to the land in correct combinations, will greatly reduce or prevent soil erosion, improve fertility, and increase yields. The basic soil types determine many of the inherent soil-related constraints (e.g. The actual art of soil conservation is based on certain basic principles which include: ADVERTISEMENTS: (i) Protection of soil from impact of rain drops (ii) To slow down the water from concentrating and moving down the slope in a narrow […] ?&�V�E�� ���Y�"����= Soil Erosion Soil erosion is a naturally occurring process that affects all landforms. 1 / 4 Introduction to Conservation Agriculture: principles and benefits Source Conservation Agriculture in FAO Keywords Soil erosion, no tillage, plants, land, soil Country of first practice Brazil ID and publishing year 7413 and 2012 Sustainbale Development Goals Zero … ���X�0UL*.P!%�4�[Z� 34 L���4(�;$�d?cP5���d�Q|�3�`�`8���`�P�}�M�p3�a������B�`���x���$��nN�� |@��a�@�>�H+�� 1!�FQ ���� Good construction management for soil conservation requires an understanding of the following basic principles: Soil Erosion Control – The First Line of Defense . 0000008617 00000 n 0000008337 00000 n Plants prevent wind and water erosion by covering the soil and binding the soil with their roots.

Wind erosion is controlled by reducing the wind erosion forces on erodible soil particles and/or by creating aggregates or soil surfaces more resistant to wind erosion forces. 0000009518 00000 n 0000005586 00000 n HF��߮ �^C���dD�9b6�!��@�\�Dkg2���0,�ܧe�ۍ�d�*7zk���v� @2p�8�a�3�����(ye֍�Ba�����a�UQ/v�絏g��u��9��A*f�n5��g%M^9��|T���_ �A�R!N���mg����ܦN;�f��h�,�@u\�����4�reGF����谿�ؽ:LI�p��q�e���� ��&�|ݔe��!P�H Erosion is caused by many different weather factors, such as wind, water, and glacial move-ment. 0000037417 00000 n 0000015719 00000 n 0000021827 00000 n �kO�3�'�������>OvmME�9�ũ��p��.�$!�8S�u�2��N�U1�=��5��]l�% �د�2���t��U�V�� ��>`v^��ؙ����P8���>n}r�4�f2$�n;H��)�gg���R�$�FA�Fi������1!�;���a��ۿ��P$��:��p=_x�T�©������'o>y��pZ�k]���e��Sh�A 3h�ψ��]o�� �*�*�;E &�,�gx?��. /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.)
