Resumo: The concept of runoff inducement for agricultural purposes is discussed in detail, its implications to the Northeast Brazilian conditions and necessity for additional research is explained. An exaustive review of the research at various places in the world is included. The latest work being carried out at the Centro Nacional de Pesquisa do Trópico Semi-Árido (CPATSA/EMBRAPA) (Center of Agricultural Research for Semi-And Tropics) is explained in detail. This work included development of eight small watersheds varying in size from 1.0 ha. to 2.7 ha, for hydrologic evaluation of various simple low cost runoff inducement methods under natural "caatinga" conditions on shallow to medium deep Latossols. The various methods of runoff inducement include combinations of intensified grassed waterways, strip cleaning of caatinga, narrow based channel terraces (or graded bunds) for soil conservation, salt treatment on cleared strips and complete clearing of caatinga with grass cover.

Inclui-se uma revisão exaustiva das pesquisas em vários países. É apresentado o trabalho mais recente atualmente conduzido no Centro de Pesquisa Agropecuária do Trópico Semi-Árido (CPATSA/EMBRAPA). Este trabalho inclui a criação de oito pequenas bacias hidrográficas variando de 1,0 ha a 2,7 ha, para a avaliação hidrológica de métodos simples e de baixo custo de indução do escoamento superficial da água de chuva em condições de caatinga natural e de latossolos rasos a medianamente profundos. Os vários métodos estudados incluem a combinação de linhas de drenagens como gramíneas, faixas desmatadas das caatingas, terraceamento, tratamentos com sal, total desmatamento e cobertura com gramíneas.Pesquisa Agropecuaria BrasileiraPesquisa Agropecuária BrasileiraSharma, Prem N.Alonso Neto, Faustino B.Porto, Everaldo R.Silva, Aderaldo de S.2014-04-16info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdfhttps://seer.sct.embrapa.br/index.php/pab/article/view/16013Pesquisa Agropecuaria Brasileira; v.19, n.8, ago. 1984; 1011-1019Pesquisa Agropecuária Brasileira; v.19, n.8, ago. 1984; 1011-10191678-39210100-104xreponame:Pesquisa Agropecuária Brasileira (Online)instname:Empresa Brasileira de Pesquisa Agropecuária (Embrapa)instacron:EMBRAPAenghttps://seer.sct.embrapa.br/index.php/pab/article/view/16013/10158info:eu-repo/semantics/openAccess2014-04-16T19:26:20Zoai:ojs.seer.sct.embrapa.br:article/16013Revistahttp://seer.sct.embrapa.br/index.php/pabPRIhttps://old.scielo.br/oai/scielo-oai.phppab@sct.embrapa.br || sct.pab@embrapa.br1678-39210100-204Xopendoar:2014-04-16T19:26:20Pesquisa Agropecuária Brasileira (Online) - Empresa Brasileira de Pesquisa Agropecuária (Embrapa)false
