RECTIFICATION OF THE RIO GRANDE-MEXICO. FEB. 1, 1933. 1631 ment are continuing to aggravate this situation, and until P!Oper grades and hydraulic conditions are introduced by artificial works, there are no means for carrying off these deposits which are en- croaching upon the carrying ca- pacity of the channel. The con- sensus of opinion of engineers who have studied the situation is that the correction lies in the plan proposed of straightening and confining the channel. One of the principal requirements to permit such artificial rectification IS the equitable adjustment of the areas which would be necessarily detached from one side of the river and attached to the other in the straightening J?rocess. The plan evolved, of haVing each Gov- ernment acquire the private titles to these equal areas for later ex- change, provides a feasible solu- tion. These areas to be acquired are generally seeped and water- logged, and so shaped and situ- ated as to be unsusceptible of proper irrigation and drainage. (7) The benefits to be derived from the straightened and recti- fied channel plans are mutual to the two Governments in affording flood protection and in permitting cultivation, improvement and set- tlement of even larger areas ad- joining the Rio Grande than are now possible under the meander- ing nver conditions. It is of ut- most importance that the Govern- ments own and control the flood channel in order that private en- croachments be defuiitely pre- vented and eliminated. Such ownership and control will also be of great assistance in the en- forcement of national immigration and customs laws of both coun- tries. (8) In giving consideration to the determination of proper and justifiable proration of costs be- tween the two countries, condi- tions other than gross and irri- gated areas are necessarily in- azolve sigue agravando ]a situa- MlDuteNo.1211olID· • • ternatloDal BOUDcla&7 Cl6n, y no es poslble lograr el CommlsaioD-CODt4. acarreo de estos dep6sitos que reducen notablemente la capaci- dad del cauce, sino hasta que se modifiquen las condiciones hi- draulicas y ]as pendientes en fonna adecuada, mediante obras arificiales. En opini6n general de los Ingenieros que han estudiado el problema, la so1uci6n consiste en rectificar y canalizar el cauce, gue es 10 que se propone hacer. Uno de los requisltos principales para realizar esta rectificaci6n artificial es el de hacer un ajuste equitativo sobre ]as parcelas que forzosamente tienen que segre- garse de un lado del Rio y pasarse al otro lado al hacer la rectifica- ci6n. Esto se logra mediante la adquisici6n por cada Gobierno de los titulos de propiedad particular sobre los terrenos por segregar, que son iguales en extensi6n, y que se canjearan al hacer las obras. Estas parcelas son terre- nos ensalitrados r pantanosos, y por su forma y sltuaci6n no pue- den regarse ni drenarse debida- mente. (7) Ambos Paises se benefi- ciaran por las ventajas que re- suJ taran a] rectificar y canalizar el Rio, pues asf se defiende ]a regi6n de las inundaciones, se aumentan las extensiones cultiva- das, las mejoras materiales y las posibilidades de colonizaci6n en las orillas del Rio, 10 que no es posib]e en las actuales condiciones divagantes de la corriente. Es de capital importancia que los Go- biemos sean dueiios del cauce mayor del Rio y tengan control sobre el a fin de evitar definitiva- mente su obstrucci6n u ocupaci6n por intereses privados. Siendo los Gobiernos dueiios del cauce, so facilitara la vi¢lancia de la fron- tera y el cumplimiento de las leyes aduanales y de migraci6n de ambos Parses.
